In-Wall Volume Control: The Russound ALT-126R is an in-wall
volume control that fits into a standard single-gang junction box. It comes with
wall plates and volume knobs in white and almond.
Ultra-Match Technology: The ALT-126R's Ultra-Match technology
allows you to easily match the load of multiple speakers to the amplifier
impedance without the need for a speaker selector or other impedance-matching
equipment. It provides impedance matching for up to 16 pairs of speakers per
Note: To access the the impedance switch, remove knob and front
plate. The front plate is attached to the frame with 4 tabs, use caution to
push the tabs out of the frame.
Performance: This in-wall volume control is designed to
handle up to 42 watts RMS and 126-watts peak power. The built-in precision
autoformers produce high-fidelity sound with excellent frequency response (20Hz
- 20kHz, +1.0/-0.5 dB at rated power). It provides maximum power transfer from
the amplifier to the speakers without heat buildup.
Volume Knob: The ALT-126R has a simple clean design with a
simple knob and standard wall plate. The knob has 11 steps of volume, plus an
off position. The volume control provides a total of 48 dB attenuation.
Connections: The volume control has two 4-pole screw
terminal blocks, one for the input from the amplifier, and one for the output to
a pair of speakers. The terminals allow you to connect up to 12-gauge speaker
wire. The terminals can be unplugged from the volume control for easier wiring.
Speaker Wire Recommendations: For most applications,
stranded 16-gauge speaker wire is recommended. For runs of over 100', 14-gauge
is recommended, while 12-gauge is recommended for runs of up to 200'.
Amplifier Power Ratings: The amplifier should provide a
minimum of 20 watts per channel RMS for each pair of speakers connected.
Speaker Impedance: The ALT-126R is designed for speakers with
impedances of 4, 6, or 8 ohms.
EZB Connecting Blocks: When connecting multiple pairs of
speakers to the system, you will need a Russound EZB-8 (sold separately)
connecting block. The EZB-8 can connect up to 8 volume controls to the
