1) Make sure the amplifier or receiver is turned Off, and that the
12 Volt power supply is not plugged in.

4) Using butt connectors, wire nuts or other wire connectors rated
for this application and the size and type of the wire being
used, make connections to the SSVC’s power and data wires as
shown in Figure 2. If several volume controls will be connect-
ed, use Russound EZB-1 and EZB-2 connecting blocks to make
wiring easier. These connecting blocks would be additional to
any connecting blocks used for the amplifier and speaker con-
nections in Figure 1.

NOTE: The EZB-1 and EZB-2 connecting blocks have connectors that are labeled L+, L-, R-, R+. You will need to
make connections to the connecting block using alias names (i.e. 12v=L+, Gnd1=L–, Gnd2=R–, Data=R+).
5) Connect the Smart Select™ Power Interrupter to the EZB-1 connecting block as shown in Figure 2. The +V
connection from the Smart Select™ Power Interrupter should connect to the terminal of the EZB-1 which cor-
responds to the +12V connection of the SSVC. The GND connection from the Smart Select Power Interrupter
should connect to the terminal of the EZB-1 which corresponds to the Gnd1 connection of the SSVCs.
6) To eliminate the risk of damaging one or more components of the Smart Select™ system, make sure that all
connections are correct and that no wires are shorted .
7) Once all connections are made, install the SSVC in the junction box or plaster ring. Insert carefully to avoid
excessive strain on the connector. Taking the time to feed the excess wire out the back of the junction box will
help you with the final assembly. If a junction box will be used, Russound recommends you use plastic junc-
tion boxes, if possible. This is to help ensure that the volume control does not short against the surface of a
metal junction box during installation or removal. The junction box must also have a depth of at least 3 1/8”.
4. Ultra-Match™ Configuration Instructions
With a few simple calculations, Russound Ultra-Match™Volume Controls eliminate the need for a speaker
selector. By determining the impedance of the system, the correct jumper settings for the volume controls can be
calculated to allow safe operation of your system.
1) Determine the minimum impedance capability of the amplifier. Normally, this information can be found near
the speaker output terminals on the back of the amplifier (look for a measurement in OHMS).
WRITE THE AMPLIFIER’S MINIMUM IMPEDANCE HERE:__________
2) Determine the impedance of your speakers. Most speakers have this information printed on the back near the
speaker terminals. Most speakers are 4 Ohm or 8 Ohm.
WRITE THE SPEAKER’S IMPEDANCE HERE:__________
** If you are using speakers of different impedances, you need to determine the average or common impedance.
For example, a pair of 4 ohm speakers can be considered 2 pairs of 8 ohm speakers.
3) Count the number of speaker pairs you intend to connect to the amplifier.
WRITE THE NUMBER OF SPEAKER PAIRS HERE:___________
Now that you have determined all this information you can calculate the settings on the Ultra-Match™Volume
Control. The Ultra-Match™Volume Controls have jumper settings on one side of the circuit board. The jumpers
have settings for 2x, 4x, 8x. These settings are multipliers and must be set according to the number of speaker

pairs you connect.
4) Calculate the system impedance:
EXAMPLE:

=
SYSTEM IMPEDANCE
8Ω SPEAKERS
=

4 PAIRS OF SPEAKERS
5) Since you have determined the system impedance you can now calculate the jumper setting needed to pro-
tect your amplifier.
EXAMPLE:

NOTE: All volume controls in the system should be set to the same jumper setting.
5. Operation Instructions
1) Make sure the amplifier or receiver is turned Off and it’s volume set to minimum.
2) Connect 12 Volt power to the Smart Select System (see Figure 2)
NOTE: The 12 Volt power supply (Russound part No. 1201A) must be connected through the Russound Smart
Select™ Power Interrupter Module (Figure 2). You may also power the SSVC system directly from the Smart AC™
Power Controller (See Smart AC™ instruction manual).
3) The status indicator light should be illuminated red on all volume controls connected. This means that the vol-
ume control is currently in Mute mode, and that the speakers are disabled.
4) Press the function control button once. The status indicator should now blink 3 times and then turn solid
green. This means that the SSVC is now in Active mode, and that the speakers are enabled.
5) Repeat step 4 on all remaining volume controls.
6) Set the Smart Select™ volume to maximum (fully clockwise).
7) Turn On the amplifier or receiver and select a music source, such as tuner or CD player.
8) Slowly turn up the amplifier or receiver volume and set it to a comfortable (not maximum) listening level. Be
careful not to overdrive your amplifier. If the sound becomes muddy or distorted, you have reached the limit of
your amplifier’s or receiver’s volume capability and should quickly reduce the volume to avoid damaging your
speakers and/or your amplifier or receiver.
NOTE: 12 o’clock on most receivers is close to full volume.
9) Adjust the volume of the SSVCs to the desired listening level.
10)To turn Off your speakers, press the function control button once. The status indicator will turn red and your
speakers will be muted again. You may also turn the volume control knob to the full counter clockwise posi-
tion to turn Off the speakers.
6. Smart Select™ Special Features Operation
In addition to On and Off control, the function control button can be used to send system-wide commands to
turn all SSVCs On or Off.
To mute all volume controls (All Off feature)
1) On any SSVC, press the function control button until the status indicator light is red.
2) Press and hold the function control button until the status indicator blinks amber.
3) All connected SSVCs will now be in mute mode.
To enable all volume controls (All On feature)
1) On any SSVC, press the function control button until the status indicator light is solid green.
