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. [. . . ] 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. If you have any questions contact Russound directly. 2. As outlined in step #1, connect the speaker wires to the connector labeled output. 3. Install the completed assembly in the junction box. 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.

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. 2. Run all outdoor wires through 3/4" PVC conduit. 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. 3. Wire the WALTx-2 as described in the Wiring Instructions section. 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. Be sure that all PVC junctions and terminations are watertight. Blowing into the open end of the conduit is one way to help find possible leaks. If the conduit loses pressure, there is probably a leak. NOTE: Insufficient sealing at any point of the conduit network may cause moisture to build up inside the WALTx-2 Volume Control. This may cause malfunction due to corrosion to occur. 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. [. . . ] 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.
