The ALTx-2D is 
  a wall-mounted, Decora® 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™ 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. 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.
