AUXILIARY INPUT
The AUX input is provided for high level program source. The out-
put from a Satellite Receiver Tuner, Tape Cassette Deck, CD
Player or other high level program source may be directly connect-
ed to this input.
R
AUX INPUT SENSITIVITY ATTENUATOR
The AUX Input is equipped with a Sensitivity Attenuator that
allows the interface of the AUX Input with Devices having a wide
range of Output Levels.

By adjusting the Input Sensitivity to the level that matches the
device used the correct interface with the Amplifier is achieved
resulting in lower overall distortion and better frequency response
characteristics.
TAPE DECK
SETTING THE AUX INPUT ATTENUATOR
Connect a Music Source to the Amplifier.
Turn Attenuator (rear panel) fully counterclockwise.
Turn AUX Front Panel Control to about 2 o' clock.
Switch Amplifier and Music Source ON.
Turn rear panel Attenuator Control clockwise slowly until desired
Output Level is achieved.
Adjust AUX Front Panel Level Control Up-Down as desired.
STEREO SUMMING
Since most Music Source Devices provide a Stereo Output the
Amplifier is equipped with two Jacks for the AUX Input (L and R).
The two Inputs are internally buffered and electronically mixed to
Mono. This system ensures that the Music Device is properly
loaded and that the Stereo Signals are correctly summed (L+R) to
Mono without distortion.
CABLE
To connect the music source devices to the AUX Input use two sin-
gle conductor shielded audio cable terminated in a single prong
phono plug on both ends.
MUTING
The AUX Input can be Muted or not when the VOX is acti-
vated by Paging from the MIC Input or the Phone Input.
The same occurs when the Direct Muting is applied. For
location and Setting of Muting Jumpers see the proper sec-
tion in this manual.
