This 10-step plus “off” speaker attenuator allows the volume of a network of 70-volt speakers to be controlled from a remote loca-
tion.The attenuator can handle speaker loads of up to 35W (max.) and fits into a double gang electrical box. Volume reduction takes
place in 3dB increments except for the 2 lowest settings, which provide 6dB reduction increments. A speaker “off” position is also
provided.

Attenuator Installation
1) Cut a rectangular hole 4-1/16” wide and 3-3/4”
high in the sheetrock where the attenuator is to be
mounted.
2) Pull approximately 12” of the amplifier and speaker
cables through the hole.
3) Push each of the separate cables through the elec-
trical box entry holes and pull about 6” of cable
out of the front of the box (see Figure 2).
4) Rotate the two screw-mounted tabs down against
the box and slide the electrical box into the open-
ing until it stops against the wall.
5) Begin to tighten both of the electrical box screws
until the box is held firmly into the wall.The clips
on the screws will rotate into place and clamp the
box against the wall.
6) Make all the necessary electrical connections as
shown in the “Attenuator Wiring” section on the
front of this sheet (see Figure 1).
7) Remove the protective plastic film covering from
the attenuator face plate.
8) Mount the attenuator to the electrical box using
the 4 screws provided. Using a Phillips head
screwdriver, screw the attenuator into place (see
Figure 3).
