Strip 1/4" of insulation from the end of each
wire. Tightly twist the end of each wire until
there are no frayed ends. Insert each wire
into the appropriate hole on the connector
blocks; secure the wiring to the connec-
tors by tightening the small connector
screws. Be certain that proper phasing is
observed—connect the positive terminals
on the V-10-50IM to the positive terminals
on the amplifier and speakers; the negative
terminals on the V-10-50IM to the negative
terminals on the amplifier and speakers.
See Figures 2 and 3.
NOTE: THE INPUTS OF THE V-10-50IM ARE THE
CONNECTOR PINS LABELED “IN”. THE OUTPUTS
ARE THE CONNECTOR PINS LABELED “OUT”. BE
SURE NOT TO REVERSE THESE CONNECTIONS OR
THE V-10-50IM WILL NOT FUNCTION PROPERLY.
4. Set the Impedence Magnification Switch as
determined by the IM charts (Figure 5 and 6).
5. Secure the V-10-50IM to the junction box.
Insert the 1-1/4" long device screws into
the oblong-shaped screw holes on the top
and bottom of the V-10-50IM. Note that the
oblong shape of the screw holes allow you
to position the V-10-50IM so that it is vertical.
Position the V-10-50IM so that the screws
are aligned with the threaded holes in the
junction box. Tighten the screws using a
phillips screwdriver.
INSTALLATION
CONSIDERATIONS
Changing the Color of the Knob
and the Decora Insert
The Decora-style insert and knob on the V-10-
50IM are removable, allowing fast and easy
color changes as needed. Inserts and knobs
are available in a variety of colors. To change
the color of your unit:
1. Obtain the appropriate knob and Decora-
style insert in the desired color from your
Jobsite Systems dealer.
2. Pull the knob off the shaft. See Figure 1.
3. Locate the two plastic mounting tabs at the
top rear of the Decora-style insert. Using
two fingers, simultaneously press both
tabs down (towards the center of the in-
sert) and forward (away from you) until the
insert pops free from its mounting slots.
4. Locate the new Decora-style insert. Hold
the volume control facing you. Insert the
two bottom tabs into the bottom slots first,
then the two tabs on the top (see Figure
1). Press carefully on the front of the insert
to snap it into place.
5. Locate the new knob. Align its flat side to
the flat side of the shaft, and push the knob
onto the shaft. Check the alignment of the
knob by turning it through all positions.
INSTALLATION
If you are installing the V-10-50IM into an exist-
ing wall, take time to consider any possible
obstructions which may be hidden inside the
wall, such as wood and metal studs; electrical,
telephone or other types of wiring; plumbing;
conduit; old wall safes; etc.
1. Install the junction box in the usual manner.
2. Run all the necessary wiring to the V-10-
50IM. Label the wires for future reference.
3. Make the connections to the V-10-50IM.
Locate the connectors for the V-10-50IM.

and Decora-style insert.

OPERATION
1. Make sure the amplifier or receiver power
is OFF and set the volume to minimum.
2. Set the V-10-50IM volume to maximum
(fully clockwise).
3. If you are using a Jobsite speaker selection
system, locate the on/off button which
corresponds to the speaker pair you wish to
play. Set it to the on position.
4. Turn on the amplifier or receiver and select a
source, such as the tuner or CD player.
5. Slowly turn up the amplifier or receiver
volume and set it to a comfortable (not
maximum) listening level. Be careful not
to overdrive or “clip” your amplifier. If the
sound becomes muddy or distorted, you have
reached the limit of your amplifier’s volume
capability and should quickly reduce the
volume to avoid damaging
your speakers.
6. Adjust the volume of the speakers to the
desired listening level using the V-10-50IM.
If all the speaker pairs in your system are
equipped with Jobsite volume controls, you
can leave the amplifier or receiver volume set
at one position and use the Jobsite controls
exclusively.
7. You can turn off the speakers by turning
the knob on the V-10-50IM fully counter-
clockwise, or by pressing the on/off button
on your speaker selector.

DO NOT OVER-TIGHTEN. In some instances,
you may need to loosen these screws several
turns to allow the V-10-50IM to fit flush with the
Decora cover plate. See Figure 4.
6. Use the shorter plate screws to fasten the
Decora faceplate to the V-10-50IM. DO NOT
OVER-TIGHTEN THE PLATE SCREWS OR YOU
MAY DAMAGE THE FACEPLATE. Line up all the
screws in the same direction for a finished look.
