3.2 Power and Data Connections (Refer to Figure 2)

IMPORTANT: If you are unsure of any of the installation proce- dures, the products should be installed by a professional custom installer.

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

2)Use 4 conductor, 2 twisted pair wire with shield and drain to make power and data connections (Russound Part No. AW2260AB).

3)Strip 1/4” of insulation from the ends of the power and data wire that will be connected to the SSVC.

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
