Connections
1. Pull speaker wires through the
installed J-box for the volume control.
2. Connect wires from the amp speaker
OUT to the FROM AMP terminal on the
volume control.
3. Strip approx 1/4” of insulation from
each conductor. Twist ends so there are
no loose ends that can cause shorts.
4. Insert the bare wires into the

Use the Speaker Wire Gauge Table to determine proper wire gauge.
Installation
1. Mount in an appropriate low
voltage J-box. Do not install in a box
with 110VAC devices. This may be
an electrical code violation in some
areas.
2. Carefully slide the connected volume
control into the J-box. Do not pinch
wires.
3. Secure volume control and wallplate
as shown.
appropriate slot. Maintain proper polarity.
5. Tighten each terminal. Pull to test the connection.
6. Repeat Steps 2-5 to connect speaker wires to the FROM SPEAKERS
terminal.

Connecting Multiple Volume Controls
The VCRI and VCSI are automatic
impedance matching volume
controls. That means multiple VCs
and speaker pair can be connected to
an appropriately powered amplifier.
There are no jumper or switch
settings as long as the overall load
does not exceed the amps capability.
1. Use the same basic instructions
for connecting the VCs to speakers
as described in ‘Connections’.
2. Connect all L+ wires to the L+
terminal on the amp. Connect All
L- wires to the L- terminal on the
amp. Connect all R+ wires to the R+
terminal on the amp. Connect All R-
wires to the R- terminal on the amp.
3. Up to 6 VCRI/VCSI with one pair
of 8 Ohm speakers per VC can be
connected to a 4 Ohm capable amp
as shown in the illustration.
4. Up to 4 pair of 8 Ohm speakers
can be connected in parallel to a
single VCRI/VCSI connected to a 2
Ohm capable amp.
NOTE: In a parallel connection, if all
speakers have the same impedance,
the total impedance is calculated
by dividing the speaker impedance
rating by the number of speakers.
