Remote Control Switchers
The RGC11, Fig. 1, is an IR Remote Controlled Line Level Gain Control Module. It permits line level gain
control of audio power amplifiers (instead of at speaker level), in multiroom installations, when highest
sound quality is desired. It may also be used in any application where IR remote control of gain is desired,
such as between the pre-out and main-in jacks of integrated amplifiers or receivers that were built without
remote control. Gain control is accomplished by way of infrared commands originating from a Xantech
RC68+ (or RC68) Programmer. The RC68+ commands are "taught" to learning devices and passed to the
RGC11 IR "IN" and "G" terminals via Xantech IR Receivers, Keypads and Connecting Blocks.

FEATURES AND SPECIFICATIONS
• Requires RC68+ (or RC68) Programmer IR codes or the MIRV1 for operation.
• Responds to 16 IR commands: Volume Up/Down Ramping, 12 Fixed Levels, Mute ON and Mute OFF.
• IR Confirm LED lights steady when power is applied and blinks off with RGC11 IR commands only.
• Gold plated RCA type input & output jacks.
• Loop-through jacks (not buffered) for "daisy chaining" multiple RGC11’s.
• Selectable IR code groups. Internal E

PROM can be set to different group codes, allowing different IR
code combinations. This prevents mutual interaction in common IR systems when using more than one
RGC11, or if RGC11's are included with other Xantech products using RC68+ codes.
