PRODUCT OVERVIEW
Introduction
The ALT-126R UltraMatch™ Volume Control is a wall-mounted standard or Decora® style stereo
speaker-level 12-step attenuator. It connects between the speaker outputs of an ampli er/receiver
and a pair (or multiple pairs) of speakers. The ALT-126R adjusts volume level by attenuating the
ampli er signal output of the ALT-126R to the speakers. It is manufactured using a high-quality
autoformer design for long life, excellent frequency response, no heat build-up, and maximum
power transfer from the ampli er to the speakers.
The UltraMatch™ designation means the ALT-126R can match the minimum output impedance of
the ampli er/receiver, in addition to adjusting volume. It eliminates the need for a speaker selector
or other impedance matching equipment. When the impedance matching switch is in 1X position
the volume control can be used as a standard control. The 2X, 4X, and 8X settings allow it to be
used as an UltraMatch™ control.
Considerations
Ampli er power rating - Make sure the ampli er has 20 watts per channel for each pair of
speakers to be connected.
How many ALT-126R - An UltraMatch™ volume control should be used for each pair of speakers
(however, up to 2 pairs of speakers can be used on each control).
Speaker rating - A minimum 4-ohm speaker load can be connected to the Output of each
UltraMatch™ volume control.
Impedance matching switch - Each ALT-126R in the system must have the impedance matching
switch positioned correctly (1X, 2X, etc.). Switch must be set BEFORE the ALT-126R is installed.
Installation location - Typical locations for ALT-126R installation include proximity to other wall
controls, near a desk or next to entrances.
Proper impedance matching switch position for UltraMatch™ Impedance Matching - ALT-126R
impedance matching switch position must be choosen to correctly multiply the impedance of the
system to a level that equals or exceeds the minimum impedance of the ampli er.
By determining the impedance capability of the ampli er with a few simple calculations, you can
determine the number of speakers the system can safely operate. The impedance matching switch
position can then be determined by using the charts on the next pages.
