SET JUMPERS FOR IMPEDANCE MATCHING

Important: A minimum speaker load of 4 ohms can be connected to

the output of each UltraMatch™ volume control.

The jumper must be set in a position that correctly multiplies the impedance of the system to a level that is equal to or greater than the impedance of the amp.

1. Determine the amplifier's minimum impedance (as listed in its owner’s manual or on its back panel).

2. Choose the correct impedance-matching chart (8 ohm or 4 ohm) shown on the reverse side of this page. If your amplifier is 6-ohm, use the 8-ohm chart.

3. Determine the total number of 4-ohm pairs of speakers (rows on charts).

4. Determine the total number of 8-ohm pairs of speakers (columns on charts).

5. Look up your correct jumper setting and set the jumpers as shown in the circuit board illustrations on the reverse side of this page.

WIRING INSTRUCTIONS

Type of Speaker Wire For most applications, we recommend you use 16 or 18 gauge, stranded

copper speaker wire for the ALTx-WIRi 2D speaker connections. For wiring runs longer than 100 feet, 12 gauge wire is recommended. Using speaker wire larger than 12 gauge for ALTx-WIRi 2D Volume Controls is not recommended as the wire may not fit into the connectors. NOTE: Never use solid-core, aluminum or Romex® type wire with volume controls. When running speaker wires inside walls, most states and municipalities in the U.S. specify that you must use a special type of speaker wire. Usually, the requirement is that the wire has a specific “CL” fire rating, such as “CL-2” or “CL-3”. Consult your Russound dealer, building contractor, or local building and inspection department if unsure about which type of wire is best for your application. If you need speaker wire, we recommend you order Russound AW Series wire. These speaker cables use multi-strand copper wire and high-temperature PVC jackets specially designed for snaking through the walls and for long speaker runs.

Amplifier & Speaker Connections

(Recommended wire use: Russound AW164CL3 (or equivalent) for runs between amp and ALTx; AW162CL3 (or equivalent) for connections between ALTx and speakers.

1. Connect the leads from the amplifier’s speaker outputs to the connector labeled INPUT on the EZB-1 connecting block. Make sure to maintain polarity (+, –) as well as channel identification (Left, Right).

CAUTION: Do not reverse the input and output connections!!

TE: A majority of receivers are designed to operate at a rating of

NO 8 ohms. On receivers that offer A and B speaker outputs, the A and B connections share the same amplifier. It is important to note, due to the way many r

eceiver matching devices, such as UltraMatch™ volume controls, it is recommended to

e all speakers to the A output. If you have any ques-

wir

3. Connect the OUTPUT on each ALTx-WIRi 2D volume control to a pair of speakers.

IR Receiver and Status Line Connections

4. Connect the IR and Status wires to the 857 connecting block as illustrated. The 857 input connector is designed to accept up to 12 AWG wire. If you are using multiple ALTx-WIRi 2D volume controls, use thinner 24 AWG wire and bundle the IR and Status wires together.

5. Use Russound AW2260AB two-pair shielded wire (or equivalent) to extend IR and status wires to the IR connecting block for best results.

INSTALLATION

The total mounting depth from the wallplate/faceplate to the back of the ALTx-WIRi 2D is 2-7/8". You must use a minimum of a standard light switch plaster ring (P-Ring) or a standard 20 cu. in. (or larger) electrical box. Suitable P-Rings and electrical boxes are available from your Russound dealer or a local electrical supply company. Using the P-Ring during new construction is best because it gives you unobstructed access to the full depth of the wall (some building codes require that wall devices be enclosed in electrical boxes; check your local building code).

Do not install the ALTx-WIRi 2D into electrical boxes with 110V devices. Some states or municipalities allow devices such as the ALTx-WIRi 2D to be installed into the same electrical box as 110V devices, provided a “lowvoltage partition” is used between the devices. Russound does not recommend this. Speaker wires can act as an “antenna” for electrical noise. Locating speaker wires too close to a light switch or dimmer switch may cause a “humming” or “buzzing” sound to be heard through the speakers. If you must locate the Volume Control near electrical devices, install it in a separate metal electrical box, ground the box to the electrical system ground, and route the speaker wires several feet away from the electrical wiring.

Install the completed ALTx-WIRi 2D assembly in the electrical box. Insert carefully to avoid excessive strain on wire connections. Taking the time to feed excess wire out the back of the electrical box will help you with the final mounting.

OPERATION

1. Make sure your audio receiver is OFF and set its volume all the way down.

2. Set the ALTx-WIRi 2D volume to maximum

3. Make certain the receiver volume is all the way down. Then turn on the receiver and select a music source, such as tuner or CD player.

4. Slowly turn up the receiver volume and set it to a comfortable (not maximum) listening level. Be careful not to overdrive your receiver. If the sound becomes muddy or distorted, you have reached the limit of your r to avoid damaging your speaker

s volume capability and should quickly reduce the volume

ALTx-WIRi 2D OVERVIEW

The ALTx-WIRi 2D UltraMatch™ Volume Control is a wall-mount stereo speaker-level volume control with built-in IR Receiver. It connects between the speaker outputs of an amplifier or receiver and a pair of speakers. UltraMatch™ is a method of matching the minimum output impedance of the amplifier or receiver, in addition to adjusting volume. It eliminates the need for a speaker selector or impedance matching equipment.

IMPORTANT – Before installation, review the manuals included with each component in your system. If you are unsure of any of the installation procedures described herein or elsewhere, consult a professional electronics installer.

ALTx-WIRi 2D FEATURES

1) Rotary control of volume level and speakers on/off

2) IR receiver

3) LED indicator for source component on/off status

4) UltraMatch™ impedance matching

5) Fits Standard and Decora® faceplates

CONSIDERATIONS

1. Make sure that your amplifier has adequate wattage for the number of speakers. Watts per channel divided by the number of pairs should equal or exceed the individual speaker’s minimum wattage requirements.

2. You must use one (1) UltraMatch™ volume control for each pair of speakers.

3. Every jumper setting must be set on the same setting throughout the system.

4. A minimum speaker load of 4 ohms can be connected to the output of each UltraMatch™ volume control.

RUSSOUND EZB CONNECTING BLOCKS (OPTIONAL)

The EZB-1 and EZB-2 connecting blocks are Russound accessories that simplify connections of multiple volume controls and speaker pairs. The EZB-1 is a neat, compact wiring device capable of connecting four volume controls to an amp’s outputs. The EZB-2 expands the EZB-1 to another 4 volume controls. Multiple EZB-2's can be used to expand the system to 16 volume controls.

RUSSOUND 857 IR CONNECTING BLOCK (OPTIONAL)

The 857 IR connecting block allows IR signals received by the ALTxWIRi 2D to be easily distributed to multiple source components via Russound 845.1 or 1584 IR emitters. The 857 and the Status feature are each powered by the Russound 846C power supply (sold separately).
