VSI45

Impedance Matching Stereo Volume Control

OWNER’S MANUAL

SpeakerCraft

®
Introduction
The SpeakerCraft VSI45 is a wall mounted impedance matching stereo volume control, which connects between
the speaker level output of an amplifier, receiver or speaker selector and a pair of speakers.
Volume Control Placement
When deciding where the volume control will be mounted in the wall, consider the various ways it will be used. The
primary listening area and the ease of running the wire to your chosen location are the important things to keep in
mind. The most common locations to mount volume controls are by the door as you walk into the room, next to
existing wall fixtures, or in the area that you will be listening to music. If you do not understand any part of these
instructions, please contact your SpeakerCraft dealer. Improper wiring could cause damage to your audio system.
Do not put the volume control into the same box as
a 110v AC circuit. (i.e. light switch, electrical
outlet, etc.). Speaker wires can act as an "antenna"
for electrical noise. Locating speaker wires too close
to a light switch or dimmer may cause a buzzing or
popping sound to be heard through the speakers.
If you must locate the VSI45 near electrical devices,
use a separate electrical box.
Once a location has been chosen, you may install
the volume control after you have first installed a
standard single gang plaster ring, or a single gang
electrical box (light switch type).
Wiring the VSI45
CAUTION: Please make sure your amplifier or
receiver is turned off before proceeding.
The VSI45 features a Removable Wire Block Terminal, which allows for
quick and easy wiring. You may find it easier to remove the wire block
terminal from the volume control before proceeding.
For best results, strip the speaker wire no more than
1
4” from the end.
Loosen the screws on the underside of the wire block terminal to allow
the wire to be pushed completely into the opening, then tighten the
screws to secure the wire. (See Figure #1) Once all wires have been
connected, replace the wire block terminal onto the volume control.
If you need to remove the wire, simply loosen the screws on the
underside of the wire block terminal.
Refer to Figure #2 when wiring the VSI45:
1. Connect the amplifier or receiver's left speaker output to the left input
terminals on the removable wire block terminal. Please observe
proper polarity of the connections (+ amplifier to + input on the
volume control).
2. Repeat step 1 for the right side.
3. Connect the wires from the left speaker to the left speaker output
terminals on the removable wire block terminal. Please observe proper
polarity of the wires for correct speaker phase (+ speaker to + output).
4. Repeat step 3 for right speaker connection.
CAUTION: If the input and output connections are reversed, the
minimum setting on the volume control will cause a short across the
amplifier or receiver output terminals, resulting in serious damage
to your amplifier or receiver. Please double check steps 1 through 4.
This volume control cannot be connected in series with another
volume control.
