Power plug
To AC wall outlet
Insert the power plug all the way and securely into a power outlet.
CD player etc.
Select the input connectors according to the type of the component connected to it.
The D.AUDIO input is provided with high input gain so that it can accept the input from the headphones out- put of a portable component such as a HDD (Hard Disc Drive) audio player. If the line output from a desktop component such as a CD player is connected to these connectors, the audio is played at a larger volume than when it is connected to the CD or AUX connectors. In this case, however, the audio may be distorted if the listening volume is set too high.
??In case an associated system component is connected, also read the instruction manual of the component.
??Be sure to insert all connection cords securely. If their connections are imperfect, the sound may not be produced or noise may interfere.

In general, the bass adjustment using the N.B. circuit is most effective when using compact speakers because the bass is often insufficient with these kinds of speakers. The N.B. CIRCUIT knob should be set to OFF with a subwoofer.
OFF : Normal playback (The N.B. circuit function is de- activated.)
1 : Enhances the low frequencies around 60 Hz.
2 : Enhances the low frequencies around 70 Hz.
3: Enhances the low frequencies around 100 Hz.
