Gooseneck Microphones and Accessories

General Description

Shure MX405, MX410, and MX415 miniature gooseneck microphones are suitable for board- rooms and other sites where aesthetics are impor- tant. Permanently mount them at conference tables or lecterns using the MX400SMP surface mount, or use the MX400DP moveable desktop base, which includes a configurable mute button with logic output. Also compatible with the MX890 wireless desktop base.

Features

???Low profile, aesthetic design

???Choice of bi-color indicator or light ring

???Wide dynamic range and smooth frequency response

???RF filtering with CommShield?? technology

???Logic input for external LED control

Interchangeable Cartridges

Microflex microphones use interchangeable cartridges that allow you

These gooseneck microphones are available in different lengths with a cardioid or supercardioid cartridge and either a bi-color LED status indicator or a light ring.

5-Pin XLR

DIP Switches

Set DIP Switch 1 up to engage the low cut filter, which attenuates frequencies by 6 dB per octave below 150 Hz.

LED Logic

To operate the LED indicator, use the included 5-pin XLR con- nector to wire the microphone to an automatic mixer or other logic device.

MX400DP Desktop Base

The MX400DP moveable desktop base includes a configurable mute button with logic output.

Desktop Base

Note: Over tightening the wing nut reduces shock isolation.

Caution: To prevent bending pins, line up key with notch and seat connector fully before twisting to lock.

Note: Connect the LED IN to the gate output to illuminate the LED when the channel is gated on.

Do not use the relay ports on Crestron and AMX devices. Use the I/O logic ports instead.

The LED logic may not function when connecting to devices that do not have internal "pull-up resistor" logic circuits, such as ClearOne DSP products. External pull-up resistor circuits can be

added for each microphone. Visit www.shure.com/FAQ for detailed instructions.

Cable

The 20 ft. attached cable is terminated with a 3-pin XLR connector. For logic applications, open the XLR connector to access the three unterminated logic conductors.

Caution: Failure to reinstall the setscrew will reduce RF immunity.

Button Configuration

For local mute control operation, use DIP Switches 1 and 2 to con- figure the button behavior.

Toggle: Push and

release to toggle

Local Mute Control

The microphone ships configured for local (manual) mute control (DIP Switch 3 down). In this mode, the PUSH button on the micro-

phone mutes the audio signal at the microphone. Audio is not sent to the audio outputs when muted.

In this configuration, the LED color reflects the microphone state, as controlled by the user with the PUSH button.

the microphone on or off. Mic is mute

when powered on

Logic Mute Control (Automatic Mixing)

Set DIP Switch 3 up to configure the microphone for logic control applications where audio from the microphone is muted by an ex- ternal device, such as an automatic mixer. In this mode, the local mute function of the PUSH button is bypassed (the microphone always sends audio) and the LED does not respond directly from pushing the button.

As required by the installation specifications, wire the SWITCH OUT conductor in the microphone cable to the automatic mixer or other TTL logic device. When the talker presses the button on the microphone, it changes the voltage level at the SWITCH OUT con- ductor, which signals the device to mute audio for that channel or perform some other function.

To control the LED on the microphone, wire the LED IN conductor to the gate output on the automatic mixer (or any TTL logic device).

Button Configuration

For logic control operation, DIP Switch 1 determines the button be- havior (DIP Switch 2 has no effect).

Momentary: When pushed, SWITCH OUT (red wire) falls to 0 V. When released, SWITCH OUT returns to +5 V.

Toggle: Push and release sets SWITCH OUT to 0 V. Push again to toggle back to +5 V.

Controlling the LED Using Logic LED IN

When configured for logic mute control, connect the LED IN con- ductors to an external switch, relay, or a TTL gate (gate out) on an automatic mixer. The MX400DB contains an internal pull-up resis- tor circuit.

???The LED illuminates green/red when the MX396 LED IN is grounded (orange wire connected to the green wire).

???The LED illuminates red/off when LED IN is lifted (orange wire is NOT connected to the green wire).

Preamp Gain

If necessary, the preamplifier gain can be reduced by 12 dB. Contact an authorized Shure service center for information.
