RAT1

REMOTE AUTO TRANSFORMER

The RAT1 is an infrared remote controlled stereo speaker volume control with impedance matching capability. It allows individual volume control of from one to 16 pair of stereo speakers from one stereo power amplifier, using one RAT1 for each stereo speaker pair. It is controlled with any Xantech IR Receiver or keypad or with Xantech MIRV1 motorized volume controls. The RAT1 maintains correct imped- ance matching between the amplifier and the speak- ers with the use of instant setting S1 to S8 jumpers, located on the unit. This eliminates the need for separate impedance matching devices in multi-room installations.
