IR/MOTORIZED VOLUME CONTROLLER
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.

FEATURES AND SPECIFICATIONS
• Servo action causes multiple MIRV1's to automatically track each other's position and simultaneously
drive the RAT1 or RGC11 volume settings.
• LED in knob blinks with knob rotation and also serves as a system ON/OFF status indicator.
• Requires IR commands from the RC68+ (or RC68) Programmer, or manual rotation, for volume
operations.
• Using the RC68+ Programmer, internal E
operation of MIRV1's in a common IR bus system.
• Factory preset Group Code number is 30.
• Plug-in 4-terminal screw-type connector for IR, STATUS and +12V.
• Recommended wire for 4-conductor bus: 24 gauge solid or stranded wire up to 150', 22 gauge up to 400',
20 gauge up to 1500' and 18 gauge up to 4000' (unshielded OK).
• Power: 12V DC @ 60 mA. Powered directly or from a RAT1.
• Use decorator-style wall cover plate.
• One nut disassembly allows custom painting of Insert Plate.
• Knob and plate are pre-finished in either white (MIRV1-W) or ivory (MIRV1-I).
• Fits standard single gang J-box.
• Depth behind plate: 2-1/8 inches.

- Page 3 NOTE: Mute is released (turned off) when a VOLUME or Preset Level button is pressed, in addition to MUTE OFF. 5. Code Group Numbers. If more than one MIRV1, RAT1, or RGC11 is used in a common IR bus controlled system, or is included with other Xantech products that respond to RC68+ commands, different code groups can be assigned, by the installer, to avoid mutual interaction.
- Page 4 Also, a 780-80 is used to give the added convenience of IR control and a status indicator voltage is supplied. The system is configured as follows: 1. The second MIRV1 and the 780-80 are simply wired in parallel with the first MIRV1 on the same 4- conductor "bus" as shown.
