Speakers & Volume Controls
INSTALLATION INSTRUCTIONS
The MIRV1 is an IR or manually operated volume controller that works in conjunction with the RAT1 Remote
Autotransformer or the RGC11 Remote Gain Control Modules. Together, they allow speaker or line level
volume control in any room, using a standard 3 or 4-conductor Xantech IR bus system. You can also use
two or more MIRV1's in the same room or listening area, for convenient manual operation, or in conjunction
with a Xantech IR receiver for both remote and manual volume operations. Knob mounted indicator allows
visual verification of volume rotation and position and also serves as a system power ON/OFF (status)
indicator.
