Cabling
Audio input and output cabling consists of 3-pin terminal blocks as shown in the audio
input/output detail below. For MONO operation, connect audio to the CH A input only and
use the six monaural outputs. For STEREO operation, connect audio to the CH A and CH
B inputs and use the three CH A and three CH B outputs as shown. Connectors grayed
out are not used for the application.
The 6600R is capable of remote gain control operation. Placing the toggle switch S1 on the
module in the REMOTE position will allow adjustment of the amplifier gain from a
external customer-supplied 10k potentiometer. The potentiometer control connection is
accomplished by utilizing the lowest most output connector for CH B on the particular
input/output group on the 6600 mounting frame. The connections are shown in the
remote gain control detail below.
