The ALTx Volume Control is a wall-mounted Decora or Standard style, stereo speaker-level volume control. 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 control. The 2X, 4X, and 8X settings allow it to be used as an Ultra Match control. The UltraMatch volume control provides a method of matching the minimum output impedance of the amplifier or receiver, in addition to adjusting the volume. It eliminates the need for a speaker selector or impedance matching equipment. The ALTx adjust volume level by attenuating the amplifier signal output of the ALTx 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.
