PREPARING FOR INSTALLATION
The Speakers/Volume Control cables, Amplifier
cables and 12V DC power supply cable must all reach
the proposed location of the V-T4M distribution
connection terminal. Mark the cables with Wire
labels, describing where the cables originate from,
rather than where they will terminate. Locate a
switched AC outlet on your Receiver or Amplifier to
be used to power theV-T4M power supply.
Calculating the Impedance
Magnification Setting:
To ensure optimal operation of your amplifier or
receiver, your speakers must show it a load that it
can handle safely and effectively. This requires the
use of impedance-magnifying (IM) volume controls.
CAUTION! Every speaker pair in the system must be
connected to an impedance-magnifying volume
control and set to the same magnification.
When you install the V-T4M and connect the volume
controls to it, double-check the DIP-switches on the
volume controls to verify that they are set correctly
for the impedance load of your speakers.
Use the following instructions and the accompanying
charts to select the correct DIP switch setting on the
volume controls for the number and type of speakers
in your system.
Some speakers have selectable impedance. Before
you proceed, please confirm that any selectable-
impedance speakers in your system are properly set
for the system you are installing.
1. Count the number of pairs of 4 ohm speakers and
the number of pairs of 8 ohm speakers you are
connecting. Count pairs of 6 ohm speakers as
4 ohm pairs.
2. Determine whether the amplifier should see a
4 ohm load or an 8-ohm load. You should find this
information in the owner’s manual of the amplifier.
3. Read the correct DIP switch position from the
charts on this page. See Figure 2 if your amplifier
can drive a 4 ohm load. See Figure 3 if your
amplifier must have an 8 ohm speaker load.
4. Set the DIP switches on all of the controls to the
same position (1x, 2x, 4x, or 8x).

INSTALLATION
1. Select an appropriate location for the V-T4M.
2. Run all the necessary wiring to the V-T4M. Label
the wires for future reference.
3. Strip 1/4" of insulation from the end of each wire.
Tightly twist the end of each wire until no frayed
ends remain.
4. Locate the Snap and lock
connectors and remove
them if they are plugged
in. See Figure 4.
5. The four-position
connector plugs are for
speaker wires; the two-
position connector plugs
are for 12V wires.
6. Use a small flathead screwdriver or your thumb to
raise the locking tabs, exposing the holes on the
connectors.
7. Insert each wire into the appropriate hole and
snap down the locking tabs.
8. Insert the smooth side of the connector plug into
the smooth side of the V-T4M socket.
9. Connect the Amplifier to the connector terminal
labeled: INPUT FROM AMP.
10. Connect the Speaker wires to the connector
terminals labeled: OUTPUTS TO VOLUME
CONTROLS.
11. Connect the 12V wires to the connector terminals
labeled: OUTPUTS TO MUTING RELAYS.
12. Plug the 12V DC power supply connector into the
V-T4M socket marked POWER.

INSTALLATION DIAGRAM PROGRAMMING MUTING VOLUME
CONTROLS
You can program individual JobSite Muting Volume
Controls, allowing certain locations (such as the
guest bedroom and porch) to remain muted when
system turns on, while other locations (such as the
kitchen and family room) play music.
Place the volume control in the desired turn-on state
(muted or unmuted) by pressing the mute button.
Then press and hold the mute button for
10 seconds. The LED blinks to indicate that
programming has occurred.
JobSite Muting Volume Controls come from
the factory pre-programmed in the automatic
mute mode.
