User manual RUSSOUND WALTX-2

[. . . ] Determining the Proper Jumper Setting for Impedance Matching The jumpers 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 amplifier. The jumper setting can be determined using the following simple steps 1. Determine the amplifier's minimum impedance. The amplifier's minimum impedance is usually found following Wattage and Frequency Response in the amplifier's specification page of the manual. It may also be listed on the back panel of the amplifier near the speaker terminals. [. . . ] Wiring Instructions 1. Connect the leads from the amplifier's outputs to the connector labeled input. The wires should stay consistent, left + of the amplifier to left + input of the volume control, observing polarity and identification. CAUTION: A majority of receivers are designed to operate at a rating of 8. On receivers that offer A and B speaker outputs, both A and B connections share the same amplifier. It is important to note, due to the way many receivers are wired, that when using impedance matching devices, such as UltraMatchTM volume controls, it is recommended to wire all speakers to the A output. 2. As outlined in step #1, connect the speaker wires to the connector labeled output. Taking the time to feed the excess wire out the back of the junction box will help you with the final assembly.

Select a suitable location for the WALTx-2. The WALTx-2 can be mounted to a hard surface (Fig 4) or can be placed directly onto 3/4" PVC conduit (Fig 5) . Do not permanently mount the WALTx-2 until you have completed steps 2 - 6. Make sure that the WALTx-2 can be accessed easily with the intended mounting position. Wiring to the speakers can be made by branching off the volume control's conduit using T- junctions, or by running a separate line of conduit from the interior of the home. 4. Be sure to test the WALTx-2 and speaker operation before attempting to secure the PVC junctions (see operation instructions below). Also be sure to test the integrity of your wire connections since all of the connections will be permanently sealed in the conduit. 5. Once the system has been tested and you are sure that the connections are secure, seal the conduit using PVC adhesive. Blowing into the open end of the conduit is one way to help find possible leaks. NOTE: Insufficient sealing at any point of the conduit network may cause moisture to build up inside the WALTx-2 Volume Control. 6. If the WALTx-2 is to be mounted to a hard surface, such as an exterior wall, use four screws and appropriate mounting anchors to permanently mount it. Operation Instructions 1. Make sure the amplifier/receiver is turned OFF and the volume is set to minimum. 2. If you are using a Russound speaker selector system, locate the ON/OFF button which corresponds to the speaker pair you wish to play. 4. Turn on the amplifier or receiver and select a music source, such as tuner or CD player. WEATHERPROOF VOLUME CONTROL 5 5. Slowly turn up the amplifier or receiver volume and set it to a comfortable (not maximum) listening level. [. . . ] To return items for repairs, the unit must be shipped to Russound at the owner's expense, along with a written explanation of the nature of the service required. The unit must be packed in a corrugated container with at least 3 inches of resilient material to protect the unit from damage in transit.
