into the same faceplate. it connects between the speaker outputs of an amplifier or receiver and a pair of speakers. the 1x setting allows the
volume control to be used as a standard non-impedance matching
control. the 2x 4x and 8x settings allow it to be used as an ultramatch
control. the ultramatch
volume control provides a method of matching the minimum output impedance of an amplifier or receiver in addition to attenuating the
volume. this eliminates the need for a speaker selector or other impedance matching equipment. the
volume is adjusted by adjusting the amplifier signal output of the
volume control to the speakers. all
russound volume controls are manufactured using a high quality autoformer design which provides long life excellent frequency response no heat build-up and maximum power transfer from the amplifier to the speakers. the built-in ir receiver will receive ir signals from a hand-held remote
control and relay this information to the audio/video equipment for operation from another room. additional wiring an ir connecting block (857) ir emitters (845.1 and/or 1584.1) and a 12vdc power supply (846c) and are also required. all
russound volume controls conform to ul standard 1492 first addition and for canada certified to csa standard 22.2 no. 1-m94. this certification assures that
