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
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.
• Factory preset Group Code number: 30
• 4-terminal plug-in for IR input & power connections, IR IN (= IR Signal), G (= GND), V V= 15VAC. Accepts
wire sizes from 24 to 12 gauge.
• Power Requirements: 15VAC @ 85 mA. (15V AC power supply included).
• Gain: Unity @ Max. V.C.
• Input Impedance: 45 k Ohms
• Output Impedance: 220 Ohms
• Freq. Response: 5 Hz to 70 kHz ± 3 dB.
• THD: < 0.01% @ 2V out.
• S/N Ratio: > 103 dB "A" WTD re 2V out.
• Flanges, plus supplied screws, permits easy mounting to flat surfaces..
• Dimensions: 5-7/8" x 2-3/4" x 1-5/8"

Be sure to set the RC68+ to the same number! It may be necessary to change the RGC11 to a different code group if it is used in a common IR bus controlled system with other Xantech RGC11's, to avoid mutual interaction. - Page 3 Block for control of the source components. 3. Since a common IR bus is used, each of the RGC11's and its connected MIRV1 (where used) must use a different IR Code Group number, so that the volume level in each room can be adjusted independent of the others.
