OWNER’S MANUAL
SS4VC
4-Pair Speaker Selector with
Impedance Balancing Volume Controls
INTRODUCTION
The SS4VC is a 4-Pair Speaker Selector with Impedance Balancing
Volume Controls which allows the operation of multiple pairs of
speakers when using one amplifier or receiver. Once the speakers
are connected to the speaker selector, individual pairs may be
turned on or off as desired using the push buttons on the front
panel. A separate volume control for each pair allows the ability to
control or limit speaker volume right at the selector.
When engaged, a protection circuit allows the amplifier to
operate safely, even when all selected speakers are playing.
Installation utilizing the Removable Terminal Connectors
makes wiring the selector to your speakers quick and easy.
With a simple turn of a screw, wires are solidly fastened and a
secure electrical bond is created. The process is quick, simple
and eliminates the worry of wires becoming loose.
INSTALLATION
Guidelines
• Use the Speaker Selector only with amplifiers rated at 125
watts per channel or less.
• The Removable Terminal Connectors on the SS4VC accept
wire up to 14 AWG. If you are not sure about the gauge of
the wire you intend to use, please consult your Proficient
installing dealer.
• To avoid possible damage to your amplifier, pay careful attention to the section titled “Operation” on page 3.
• One set of adhesive area labels are included for identifying
the locations of speakers on the front of the Speaker Selector.

• Do not daisy chain (hook the outputs of one selector into the
inputs of another) speaker selectors together.
• Do not connect impedance matching volume controls to the
speaker outputs of the selectors. Standard volume controls,
such as Proficient models VCS60, VC60SL and VC60AW should
be used if separate room control is desired.
Placement
The suction feet securely hold the SS4VC in place when buttons
are depressed.

For best results, use speaker wire that is at least 16 gauge. For runs longer than 75 feet, 14 gauge wire is recommended. For best
results, strip all wire insulation no more than 3⁄8" from the end before inserting into the connector.
1. Remove the Terminal Connectors from their locations on the back of the cabinet. This will make it easier to connect the wires.
(See Diagram 3)
2. Connect the wires from the speakers to the appropriate location under “SPEAKERS” on the removable terminals. Please observe
proper polarity (+, –) of the connections. (See Diagram 3)
3. Insert the wired terminal connector into the appropriate speaker output on the back of the speaker selector.
4. Connect the amplifier or receiver speaker output to the appropriate location under ”AMPLIFIER” on the removable terminal.
Please observe proper polarity (+, –) of the connections. (See Diagram 3)
5. Insert the wired terminal connector into the amplifier input on the back of the speaker selector.
CAUTION: If the ”AMPLIFIER” and ”SPEAKERS” connections are reversed, a short could result across the amplifier or receiver output terminals, which may seriously damage your amplifier or receiver. Please double-check all connections before turning on
your amplifier or receiver.

There is one set of adhesive labels included to be used on the front of the SS4VC. These labels make it easy to identify which area
has been selected when the button is depressed. There are indentations above each button on the front of the Selector. Place
the appropriate label into each of these locations. If you can't find the label you need, you can create your own by writing on one
of the blank labels using a pen or small marker.

OPERATION
Understanding the Protection Circuit
To prevent damage to your amplifier or receiver, the SS4VC features protection circuitry. When engaged, the protection feature
prevents damage from occurring to your amplifier or receiver.
When to Use the Front Mounted Protection Button
The front Protection button (See Diagram 5) should be engaged under the following circumstances to best protect your amplifier
or receiver. Protection is ”ON” when the button is depressed:
Speakers Selected Front Protection Button
1 or 2 pairs of 8Ω speakers OFF
3 or more pairs of 8Ω speakers ON
1 pair of 4Ω speakers OFF
2 or more pairs of 4Ω speakers ON
A combination of 4Ω and 8 Ω speakers ON
PROTECTION
Diagram 5
When to Use the Rear Mounted Protection Switch
On the back of the selector there is a slide switch labeled ”Continuous Protection” (See Diagram 6). When this switch is in the ”ON”
position, it will override the front Protection button and assure that the protection circuitry is always on, no matter what the
position of the front button.
This switch should be placed in the ”ON” position if you are concerned that someone
unfamiliar with the system may fail to properly use the front protection button.

Selecting Speakers
To turn on a pair of speakers, simply depress the button associated with that pair.
Please take precautions to make sure that the amplifier volume is not set at a high
level before you depress the button.
Diagram 6
Using the Volume Controls
1. Select a pair of speakers as described above.
2. Turn up the volume on the receiver or amplifier until it reaches your desired listening level. It should not be so high that your
amplifier sounds distorted, this could harm your speakers.
3. You can now use the knob which corresponds with the speaker pair you selected. Rotating the knob completely counterclockwise
will turn the volume off.
4. Control the volume of the selected pair of speakers or limit the maximum sound output of the selected pair if used in conjunction
with another, non-impedance matching volume control.
