Important Safety Information

Verify Line Voltage Before Use

Your new Citation 5.1 ampli???er has been factory con???gured for a speci???c line volt- age: 110-120 volts for North America or 220-240 volts in most other countries. Connecting the ampli???er to a line voltage other than that for which it is intended can create a safety and ???re hazard, and may damage the ampli???er.

If you have any questions about the voltage requirements for your speci???c model, or about the line voltage in your area, contact your Citation dealer before plugging the unit into an AC wall outlet.

Verify AC Circuit Capacity Before Use

High power output of your Citation ampli???er requires heavy current draw under full load conditions. To insure proper performance, and to avoid potential safety hazards, we recommend that it be connected to a circuit with 20 ampere capacity. Connecting multiple ampli???ers to the same circuit, or connecting it to a circuit used by other heavy power devices such as high wattage lights may cause circuit breakers to trip. It is always a good idea to avoid using any audio equipment on the same AC circuit as equipment with motors, such as air conditioners or refrigera- tors. This will lessen the possibility of power variation and electrical start-up noise affecting your sound system.

Do Not Use Extension Cords

To avoid safety hazards, use only the power cord supplied with your unit. If a replace- ment cord is used, make certain that it is of similar gauge. We do not recommend that extension cords be used with this product. As with all electrical devices, do not run power cords under rugs or carpets or place heavy objects on them. Damaged power cords should be replaced immediately with cords meeting factory speci???cations.

Handle the AC Power Cord Gently

When disconnecting the power cord from an AC outlet, always pull the plug, never pull the cord. If you do not intend to use the ampli???er for any considerable length of time, disconnect the plug from the AC outlet.

Do Not Open the Cabinet

There are no user serviceable components inside this product. Opening the cabinet may present a shock hazard, and any modi???cation to the product will void your guarantee. If water or any metal object such as a paper clip, wire or a staple acci- dentally falls inside the unit, disconnect it from the AC power source immediately, and consult an authorized service station.

Installation Location

???To assure proper operation, and to avoid the potential for safety hazards, place the unit on a ???rm and level surface. When placing the unit on a shelf, be certain that the shelf and any mounting hardware can support the ampli???er. Remember, the Citation 5.1 weighs over 60 pounds.

???High powered audio ampli???ers such as the Citation 5.1 may develop moderate amounts of heat. Therefore, if the unit is installed in a cabinet it is recommended that the rear of the cabinet be left open to permit air circulation. If that is not possible, ventilation holes should be placed at both the top and bottom of the cabinet or enclosure, or at the sides, bottom and top. A minimum of six (6) inches should be provided between each side of the unit and the cabinet, and at least twelve (12) inches above and two (2) inches below the unit. In some cases a fan may be required to provide for air movement within a cabinet. Please consult your dealer or installer for more information.

???Do not place the unit directly on a carpeted surface.

???Avoid installation in extremely hot or cold locations, or in an area that is exposed to direct sunlight or heating equipment.

???Avoid moist or humid locations.

???Do not obstruct the ventilation slots on the top of the unit, or place objects directly over them.

???Speaker wiring, input cables and power cords should be carefully placed so that they do not come in contact with, or intefere with the external heat sinks.

Cleaning

When the unit gets dirty, wipe it with a clean, soft, dry cloth. If necessary, ???rst wipe the surface with a soft cloth slightly dampened with mild soapy water, then a fresh cloth with clean water. Wipe dry immediately with a dry cloth. NEVER use benzene, thinner, alcohol or any other volatile cleaning agent. Do not use abrasive cleaners, as they may damage the ???nish of metal parts. Avoid spraying insecticide near the unit.

Moving the Unit

Before moving the unit, remove any interconnect cords, and unplug it from the AC outlet.

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

CAUTION: To prevent electric shock, do not remove the grounding plug on the power cord, or use any plug or extension cord that does not have a grounding plug provided. Make certain that the AC outlet is properly grounded. Do not use an adapter plug with this product.

Each of the four ampli???cation channels has a separate power supply, which means that it delivers audiophile per- formance no matter which con???guration is selected. You may operate the 5.1 in a two, three or four-channel mode, and bene???t from the following array of sophisti- cated features:

???Ultrawide bandwidth design

???Low negative feedback

???Fully complementary bipolar circuitry with over-designed output stage for high reliability

???Low harmonic and intermodulation distortion

???Massive heat sinks for silent convection cooling

???High current power supply design with massive torrodial transformer

???Quad mono power supply

???New, linearized pre-driver stage circuit

???Remote turn on/turn off circuitry with automatic sequencing

Unpacking and Installation

The carton and shipping materials used in protecting your new ampli???er were spe- cially designed to cushion it from the shocks and vibration of shipping. We suggest that you save the carton and packing materials for use in shipping if you move or should the unit ever need repair.

To minimize the size of the carton in storage, you may wish to ???atten it. This is done by carefully slitting the tape seams on the bottom and collapsing the carton down to a more two-dimensional appearance. Other cardboard inserts may be stored in the same manner. Packing materials that cannot be collapsed should be saved along with the carton in a plastic bag.

In order to assure a high level of performance and long life, the Citation 5.1 has been engineered from robust materials. This weight, however, requires, that you pay special attention to unpacking and installation of the unit. First, you may wish to have someone help you remove the unit from its carton and place it in the prop- er location. In addition, when moving the ampli???er, be careful not to set it down on the heat sink edges to avoid damage to their surface or ???nish. Similarly, be care- ful to avoid scratching any contact surface with the heat sinks, as their edges may be sharp.

Make certain that any shelf or stand is capable of supporting the weight of the ampli???er. This is particularly true if you will be stacking multiple ampli???ers on the same shelf.

When positioning the ampli???er in its ???nal location, make certain that it has ade- quate ventilation on all sides, as well as on the top and bottom. Do not place CDs, record jackets, owner???s manuals, or other paper, on top of, or beneath the unit, or between multiple ampli???ers in a stack. This will block air ???ow, causing degraded performance and a possible ???re hazard. If the unit is to be enclosed in a cabinet or rack, make certain that there is adequate air circulation, with a means provided for hot air to exit, and for cool air to be brought in. In some instances, a fan may be required for this purpose. If you are in doubt as to the ventilation requirements, please consult with your dealer or installer.

When stacking multiple Citation 5.1 ampli???ers in a rack or cabinet, place the unit which will power front and/or center channel speakers at the bottom of the stack. Next, place the ampli???er used for surround speakers in the center. The unit which will be used to power subwoofers should be at the top of the stack.

Rear Panel Connections

Bridged/Normal Switches: These switches control the output configuration of a pair of channels. Switch them down for normal use. Switch them down to ???bridged??? to combine amplifier channels for higher power output. See page 13 for more information on channel configuration and bridging.

Power Cord Connector:

Connect the AC power cord here.

Audio Input Connections: See page 13 for information on proper connections and input configurations.

Speaker Connection Binding Posts: Connect the wire running to your speakers to these binding posts. See page 11 for information on channel configurations connections. See page 17 for information on connecting speaker wire to the terminals.

8

Power Control Connections

The Citation 5.1 ampli???er features a built-in system that will automatically turn on the ampli???er when another device in the system is switched on. To activate this system, the 5.1 must be used in conjunction with a Citation Surround Controller or Processor, other Citation Power Ampli???ers, and other approved devices.

Remote Turn On With a Citation Controller or

External Trigger Control Device

The ???rst connection is to link your ampli???er to the controlling device. Connect the ???PWR??? Trigger output at the rear of a Citation Processor or an approved control device to the ???Remote DC IN??? connection on the rear panel of your 5.1. Make certain that the controlling device sends a 4.5 VDC to 12 VDC signal whenever it is turned on. If you are using a Citation 7.0 Controller, be certain to use the ???PWR??? control trigger, not one of the numbered programmable trigger outputs.

Figure 1 Remote Turn On Connections

9

If this is the only remote controlled ampli???er in the system, no further connections are needed. If multiple remote controlled ampli???ers are used, connect the ???Remote DC OUT??? jack on one ampli???er to the ???Remote DC IN??? on the next unit in the system.

Finally, make certain that the ???manual/remote??? switch on the rear panel is in the ???remote??? position to activate the remote control circuits.

If the ampli???er is to be controlled manually, the toggle switch should be in the ???manual??? position, and power will be switched on and off using the master power switch on the rear panel.

Remote Turn On Using External AC to DC Power Converter

If the 5.1 is not used with a compatible Citation Controller/Processor or other approved external device that is capable of generating turn on control voltages, it is still possible to activate the unit for automatic turn on.

To control the ampli???er in this fashion you will need a small AC to DC power converter, capable of delivering a 4.5 to 12 volts DC signal at 100 milliamperes. The DC voltage should terminate in a standard mini plug with the positive voltage going to the tip and the negative voltage going to the ring. This type of converter may be obtained at Radio Shack stores as catalog #273-11454.

Plug the AC adapter into a switched outlet that will be activated when you wish to have the ampli???er(s) turn on. This may be the switched outlet at the rear of an AC receiver or other audio equipment, an AC outlet that is part of a current sensing control unit that is activated by a preamp or surround processor, or a switched AC wall outlet.

The DC output jack should be connected to the ???DC IN??? jack on the rear of the 5.1 ampli???er. If there are additional ampli???ers in the system, they may be connected by running a cable from the ???DC OUT??? jack on the ???rst ampli???er to the ???DC IN??? jack on the second, and so on.

Before turning on the ampli???ers, be certain that the ???manual/remote??? switch on the rear panel is in the ???remote??? position.

The ampli???ers will now turn on in sequence when power is applied to the AC out- let where the converter is plugged in. The ???rst unit will turn on, and then each suc- cessive unit will come on following a short pause.

10

Channel Con???gurations

The Citation 5.1 may be used in a variety of con???gurations. Consult your dealer or installer for advice on which may be best for your system and listening requirements.

Four-Channel Operation

In multi-channel use such as a home theater system, the four channels may be allocated in a variety of ways. In some applications, they will be used to drive the left, center and right channel front speakers, with the fourth channel devoted to a subwoofer. Although you may wish to power each subwoofer with a separate, or even bridged ampli???er channel, the exceptional power supply capability of the 5.1 will also permit you to power the three front speakers as well as a pair

of subwoofers, provided that they are no less than 6 ohms each and they are connected in parallel.

For systems using Citation or Fosgate???Audionics brand Dual Drive??? surround dipole speakers, the 5.1 may be used to power all four rear channels with a single ampli???er.

Three-Channel Operation

For installations where higher power is desired for a center channel speaker, the 5.1 may be operated in a three-channel mode. Left and right front channel feeds are run through two unbridged channels, while the center channel is operated in a bridged mode. This allows the greater output demands of a center channel to be met, while still delivering power with headroom to spare for the left and right channels.

In systems with conventional surround speakers, a three-channel application may be to feed the two rear channels in an unbridged mode, while the remaining two ampli???er channels are bridged together to power a subwoofer.

Two-Channel Operation

The immense power capability of the Citation 5.1 allows it to be used in a dual bridged mode as a conventional stereo ampli???er. For critical music listening, this will permit you to drive virtually any full range speaker in the largest home acousti- cal and physical space, delivering classic two-channel stereo sound at its ???nest.

For home theater applications, the Citation 5.1 may be operated in a dual-bridged mode to power two subwoofers in large room-size installations.

Caution: When used in the dual-bridged mode, the Citation 5.1 is capable of very high peak current outputs. Please make certain that your speakers are capa- ble of handling this level of power before using the ampli???er in this mode.

11

System Connections

Note: When making connections between any source components or proces- sors or preampli???ers and the Citation 5.1, or when making any connections to speakers, be certain that both the input device and the ampli???er are turned off. To assure that there will be no unwanted signal transients that can damage equipment or speakers, it is always best to unplug all equipment before making any connections. Modern electronic products often have a ???standby??? mode that may be activated even though the product may appear to be turned off.

As a general rule, avoid running any input signal or speaker wire connections in parallel with each other, or with AC power cords. This can result in undesired hum or other interference that will greatly degrade signal performance.

When making connections with ???RCA??? type plugs on interconnect cables, make certain to gently, but ???rmly insert the plug into the jack on the back of the Citation 5.1. Loose connections can cause intermittent sound and may damage your speak- ers. The barrel assembly of some high quality RCA plugs may be very tight, and it is important to assure a proper connection between the interconnection cable and the input jack.

12

Input and Bridging Connections

The RCA jacks and bridging switches on the unit???s rear panel are used to connect your surround processor or preampli???er to the ampli???er, as well as to select the channel con???guration. Once you have determined what the channel con???guration will be, connect the output of your system to the ampli???er as follows:

Citation 7.0 Controller

Figure 2 System Connections

13

Four-Channel Operation:

Using high quality interconnect cables, connect one output of your processor to an ampli???er input channel. There is no special priority as to which speci???c channel (i.e. left, right, center, etc.) is connected to which ampli???er channel when all four channels are used individually. You need only remember what the channel is, so that the proper speaker may be connected to the correct output.

Make certain that both bridging switches are in the ???normal??? position. The toggle switches should be pointing up for both inputs.

Connect the wire running to each speaker to the appropriate output channel as shown on the speaker icons to the right or left of the speaker connection binding posts. (Figure 2A) The ???+??? or ???positive??? connection goes to the top binding post with the red barrel. The ???-??? or ???negative??? connection goes to the bottom binding post with the black barrel.

TO PROCESSOR

Figure 2A Four-Channel Operation with Dual Drive Dipoles

Three-Channel Operation:

When one high-powered channel and two medium-powered channels are required, the three-channel mode is used. Using high quality interconnect cables, link the output of your processor or preampli???er for the moderate powered channels (left/right front or surround channels) to the input connectors marked ???Channel One??? and ???Channel Two???. Be certain that the bridging switch on the left side of the rear panel, above the inputs for Channel One and Channel Two, is in the ???Normal??? position with the toggle switch pointing up.

Connect the output from your processor or preamp which is to be connected to the higher powered ampli???cation channel (center or subwoofer channels) to the input connector marked ???Channel Three??? on the rear of the Citation 5.1. The input connection for ???Channel Four??? is not used in this con???guration. (Figure 2B)

14

TO PROCESSOR

Note: Switch on left (ch. 1 & ch. 2) is in the ???Up??? or ???Normal??? position.

Switch on the right (ch. 3 & ch. 4) is in the ???Down??? or ???Bridged??? position.

Figure 2B Three-Channel Operation

To bridge the two channels, put the switch between the two input connectors in the ???Bridged??? position with the toggle switch pointing down.

In this con???guration, connections to the speakers receiving the normal power feed from the unbridged channels should be made to the connectors for Channels One and Two in the normal fashion. That is, connect the wire running to each speaker to the appropriate output channel as marked. The ???+??? or ???positive??? connection goes to the top binding post with the red barrel. The ???-??? or ???negative??? connection goes to the bottom binding post with the black barrel.

The connection for the higher power, (bridged) channel should be following the connection diagram between the speaker connection binding posts for Channel Three and Four. Connect the ???+??? or positive connection going to the binding post marked ???+??? for Channel Three to the ???+??? or ???red??? terminal on the speaker. The connection going to the negative terminal on the speaker should be connected to the binding post marked ???+??? for Channel Four. (Figure 2B)

To complete the bridging of the circuits, use one of the jumpers packed with the 5.1 to make a connection between the Negative (???-???) speaker connection terminals for Channel 3 and Channel 4 as shown in Figure 2B.

WARNING: The jumper connection should not be made when the ampli???er is turned on. This connection must be made before operating the ampli???er in a bridged mode.

Two-Channel Operation:

In this mode two high-powered channels are provided for subwoofer use, or for high-powered conventional stereo applications. Using high quality interconnect cables, connect one output from your preamp or processor to the input connector marked ???Channel One???, and the other to the input connector marked ???Channel Three???. The input connectors for channels Two and Four are not used in this con- ???guration. (Figure 2C)

15

TO PROCESSOR

Note: Both switches should point Down to the ???Bridged??? position.

Figure 2C Two-Channel Operation

For two-channel use, make certain that BOTH bridging switches are engaged by switching them down, to the ???bridged??? position.

In the bridged mode, the connections to your speakers should be made using only the top row of binding post connections. Follow the connection diagram that is between the speaker connections. For the speaker connected to the Channel One input, connect the ???+??? terminal of the Channel One output to the wire going

to the ???+??? or red colored connection on your speaker. Connect the ???+??? terminal of the Channel Two output to the wire going to the ???-??? or black terminal of your speaker.

Repeat this procedure so that the input signal connected to the Channel Three input connector is connected to your speaker using the ???+??? speaker output con- nector of Channel Three as the ???+??? or ???red??? wire, and the ???+??? speaker output connector of Channel Four as the ???-??? or ???black??? wire.

To complete the bridging of the circuits, use the jumpers packed with the 5.1 to make a connection between the Negative (???-???) speaker connection terminals for Channel 1/Channel 2, and Channel 3/Channel 4 as shown in Figure 2C.

WARNING: The jumper connections should not be made when the ampli???er is turned on. This connection must be made before operating the ampli???er in a bridged mode.

Note: When using the 5.1 in a dual-bridged con???guration, particularly with 4 ohm speaker loads, it will probably be necessary to provide additional cooling using a small fan. This cooling will also be needed in the dual-bridged mode if the ampli???er is enclosed in a cabinet. Consult your dealer or custom installer for more information.

16

Speaker Wire Preparation and Connection

Once the proper hookup has been selected using the previous section, make the physical connection using the following instructions.

Cables or Connecting Wire

To assure that the high quality signals produced by your Citation ampli???er are car- ried to your speakers without loss of clarity or resolution, we recommend that you use high quality speaker cable. Many brands of cable are available, and the choice of cable may be in???uenced by the distance between your speakers and the ampli???er, the type of speakers you use, personal preferences, and other factors. Your dealer

or installer is a valuable resource to consult in selecting the proper cable for connections between your ampli???er and speakers.

Regardless of the brand or type of cable selected, we recommend that you use a cable constructed of ???ne, multi-strand copper with a AWG of 14 or larger. Remember, that in specifying cable, the lower the number, the thicker the cable.

Cable with an AWG of 16 may be used for short runs of less than ten feet. We do not recommend that you use any cables with an AWG equivalent of 18 or higher due to the power loss and degradation in performance that will occur.

One way to insure that cables will deliver a predictable level of performance is to use cables that are Home THX?? certi???ed. This certi???cation assures that the cables have met a rigorous set of speci???cations designed for home theater applications.

Cables that are run inside walls should have the appropriate markings to indicate listing with UL, CSA or other testing agency standards. Questions about cables inside walls should be referred to your installer or a licensed electrical contractor who is familiar with the NEC and/or the applicable local building codes in

your area.

Connections to Speakers

Regardless of the channel con???guration used, the ???nal step of the installation process is to connect the ampli???er to your speakers, using high quality cable, as outlined above. A pair of binding posts is provided for each channel output. These posts will accept bare wire, spade lugs or banana-type plugs where permitted by local safety agencies.

If bare wire is used for the connections, strip approximately 1/2 inch to 3/4 inch (20mm) of insulation from the end of each wire and carefully twist the strands of each conductor together. Be careful not to cut the individual strands or twist them off; for optimal performance, all strands must be used.

Then, loosen the knobs of the speaker output terminals, far enough so that the pass-through hole is revealed. Note that one conductor of the speaker cable may have no markings, and the other will have a red line, brand name markings, a black thread, or some other positive indication. Follow the proper connection instruc- tions for your system with regard to which terminals are used. The small speaker

17

icons next to each pair of terminal posts will guide you to the correct connections. When the connections are made, twist the cap back so that the connection is secured, but do not overtighten or use tools, as this may break the delicate wire strands and decrease system performance. Also, make certain that the wire strands connected to one terminal do not contact the other terminal or wires. This will result in a short circuit.

If you are using spade lugs, connect them to the wire using the manufacturer???s instructions, and then loosen the caps on the speaker terminals. Place lugs between the plastic cap and the back of the terminal, as if it were a horseshoe on the game???s post. Be sure to observe proper polarity, using the appropriate speaker hookup icons for your system???s con???guration. Tighten with your ???ngers to obtain a positive contact.

When banana plugs are permitted, connections may be made by simply inserting the jack af???xed to your speaker wire into the hole provided on the rear of the col- ored screw caps on the binding posts. Before using banana-type jacks, make certain that the plastic screw caps are ???rmly tightened down by turning them in a counter- clockwise direction until they are snug against the chassis. This will insure that the maximum surface area of the plug is in contact with the jack. Be certain to observe proper polarity.

Finally, run the cables to the speaker locations. It is highly recommended that the length of cable connecting any pair of speakers is identical. For example, make cer- tain that the cable length connecting left and right front, or left and right rear (sur- round) speakers are identical, even though one speaker may be physically closer to the ampli???er than the other. Do not coil any excess cable, as this may become an inductor that creates frequency response variations in your system.

Finally, connect the wires to the speakers, again being certain to observe proper polarity. Remember to connect your ???negative??? or ???black??? wire to the matching ter- minal on the speaker. Similarly, the ???positive??? or ???Red??? wire should be connected to the like terminal on the speaker.

Note: While most speaker manufacturers adhere to an industry convention of using black terminals for negative and red ones for positive, some manufacturers may vary from this con???guration. To assure proper phase connections, and opti- mal performance, consult the identi???cation plate on your speaker terminals, or the speaker???s manual to verify polarity. If you do not know the polarity of your speaker, ask your dealer or installer for advice before proceeding, or consult the speaker???s manufacturer.

18

Operation

Operation of the Citation 5.1 is simple. There are no controls to adjust once the installation is complete.

After all connections have been made to the ampli???er???s inputs and speaker termi- nals, connect the AC power cord to the socket on the rear panel. Make certain that the master power switch on the rear panel is in the OFF position. Connect the power cord to an AC outlet.

Note that it is not recommended that you connect multiple 5.1 Ampli???ers to the same AC power circuit unless they are used with the remote power turn on and sequencing system. The simultaneous turn on of multiple ampli???ers on the same circuit may cause circuit breakers to trip.

Note: Do not attempt to defeat the grounding plug on the power cord. This will cause a safety hazard. It will also increase the chance of unwanted hum appearing in your system. If a properly grounded AC outlet is not available, contact your installer or a licensed electrician for assistance.

At this point you are ready for listening: First, turn on the source components and processor in your system. It is always a good idea to turn on your ampli???er LAST. This avoids the possibility of any turn on pops or transients from other equipment being ampli???ed and sent to your speakers where they may cause damage. Always start with a low volume level on your controller or preamp to avoid damage to your speakers.

For Manual Operation:

If the unit is not being used with the automatic, remote turn on system, place the ???manual/remote??? toggle switch in the ???manual??? position. Switch the rear panel master power switch to the ON position. The LED below the Citation name on the front panel will illuminate and turn blue to let you know that power is applied. There will be a short pause between the time the power is turned on until power is applied to the speakers. This is intentional, and it protects your speakers from damage as the ampli???er stabilizes. You may also hear a relay click as during start-up. This is also normal.

You are now ready to enjoy the ???nest sonic performance available. All volume and level adjustments are made at your preamp, controller or surround processor.

To turn the unit off, switch the rear panel master power switch to the OFF position.

19

For Automatic Operation:

Make certain that all connections to the Citation Controller or Processor, and to any other Citation power ampli???ers in the system have been correctly made as shown on pages 13 through 16. Switch the ???manual/remote??? toggle switch on the rear panel to the ???remote??? position. Turn the master power switch ON, position. The LED below the Citation name will turn amber to indicate that the unit is in the ???standby??? mode with AC power applied.

Your Citation 5.1 ampli???er will now turn on automatically whenever the processor or controller is switched on. You may verify that your ampli???er has been turned on in response to the control signal by noting that the LED below the Citation name will change from amber to blue. There will be a short second pause between the time the signal is applied and the indicator changes color until power is applied to the speak- ers. This pause is intentional, and it protects your speakers from damage as the ampli- ???er stabilizes. You may also hear a relay click as during start-up. This is also normal.

Once your system is turned on, you are ready to enjoy the ???nest sonic performance available. There are no controls to adjust on the Citation 5.1 ampli???er. All volume and level adjustments are made by your preamp, controller or surround processor.

There is no need to turn the ampli???ers off manually. Simply turn off the Citation Controller or Processor, or the device providing the automatic control voltages and the 5.1 ampli???er will go into a standby mode. Turn off and return to a standby mode may be con???rmed by noting that the LED indicator under the Citation name on the front panel turns from blue to amber.

Important Note: If you will not be using your audio system for an extended period of time, such as a vacation, it is always a good idea to turn the unit off using the rear panel power switch. This will prevent the automatic turn on cir- cuits from accidentally turning the system on during your absence.

20

Input/Output Protection

Under some conditions, such as a shorted speaker wire, DC voltage on an input connection or thermal overload, the Citation 5.1 will place itself in a ???protect??? mode to prevent damage to your speakers. When this happens the power indicator will turn red and no signal will be heard. You may hear a relay ???click??? on as the unit goes into its protection mode.

When this occurs, turn the unit off using the rear panel switch, and correct the problem. Turn the unit back on. If the unit continues to go into a protect mode, contact your dealer or installer for assistance.

Troubleshooting Guide

The Citation 5.1 is designed for trouble free operation. In normal use, most users will not encounter any problems with the unit. However, as with any sophisticated electronic device, there may be occasional problems on initial installation, or during the life of the unit. The items on this list are a brief guide to the minor problems that you may be able to correct yourself. If these solutions do not rectify a problem, or if the problem persists, contact your dealer, installer or an authorized Citation service center for assistance.
