MULTI-CHANNEL AUDIO MIXING

The R170 receiver offers a unique feature that eliminates the necessity of using an external audio mixer

in multi-channel applications. When using two or three R170 receivers together, the LINE OUT and

AUDIO IN jacks provide "unity gain" mixing of the audio signals. This means that the audio output of

the receivers may be mixed together through these connectors without affecting the volume levels.

Connect the LINE OUT jack of one receiver to the AUDIO IN jack of the next receiver, then connect its

LINE OUT jack to the AUDIO IN jack of the next receiver, forming a "chain" as shown in the illustration.

Up to three (3) receivers may be interconnected in this manner (combining the audio outputs of all

three) so that a single audio output is available from the output of the last receiver in the "chain".

The output level of the LINE OUT RCA jack is not affected by the VOLUME ATTENUATOR control.

The VOLUME ATTENUATOR control on the last receiver in the "chain" will control the combined

volume of all the receiver outputs. In order to control the receiver outputs independently, you will need

to use an external microphone mixer without the "jumper" cords shown below.

MIXING AN EXTERNAL TAPE DECK WITH RECEIVER OUTPUT

A tape player may be connected to the AUDIO IN jack on the rear panel to mix the tape player output

with the receiver output. Adjust the volume of the tape player with the volume control on the tape

player since there is not a separate control for this purpose on the receiver.
