Russound Volume Control with Standard Cover Plate. The ALTx-2 is a wall-mounted,
Standard style, speaker-level, UltraMatch™ 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 non-impedance
matching control. The 2x, 4x, and 8x settings allow it to be used as an UltraMatch™
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.
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 Russound volume controls are designed and tested for safety.
