This example is used to simultaneously control the Left and Right
Level Controls from a remote location with a simple connection
on the back of the unit. A 10k pot will provide approximately 0 to
30 dB of attenuation. A 100k pot will provide about 0 to 60 dB of
attenuation. If desired‚ a control voltage can be inserted to
"command" attenuation instead of a pot. This voltage is inserted
into the "C" input and is positive referenced to SHD. Note: The
control voltage should never exceed 11 volts DC.

This example shows the connection for remote selection of the
Channels 7 or 8 input select feature. The selection is done by
connecting a momentary switch between SEL and SHD. Each time
the switch is activated‚ the channel selection is toggled and alternated
between Channel 7 and 8. This remote operation functions in
conjunction with the front panel Select Control. A bi-color LED or 2
individual LEDs may be connected as shown in the diagram for
remote indication of the selected stereo line input. Note: The IND
circuit can supply a maximum of 6 mA for the LEDs.
