Considerations
1. Make sure that your amplier 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 impedance matching volume control for each pair of
speakers.
3. Every impedance switch 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 volume control.
Once the impedance setting has been determined, set the
impedance switch to the appropriate positions, either 2X, 4X, or
8X, as shown in the diagram below.
WALTx-2 - Weatherproof Volume Control
Instruction Manual:
Product Overview
The WALTx-2 Weatherproof Volume Control is designed to provide volume
control for outdoor or wet locations and can be mounted on an exterior
wall or hard, at surface, as well as directly on a section of 3/4” PVC
conduit. The WALTx-2 provides superior protection against moisture from
rain, splash or sauna.
The WALTx-2 connects between the speaker outputs of an amplier or
receiver and a pair of speakers. The 1X setting allows the volume control
to be used as a standard control. The 2X, 4X, and 8X settings allow it to
be used when more than one pair of speakers is connected to the same
amplier.
The impedance matching of the WALTx-2 volume control provides a
method of matching the minimum output impedance of the amplier
or receiver, in addition to adjusting volume. It eliminates the need for a
speaker selector or impedance matching equipment. The WALTx-2 adjusts
volume level by attenuating the amplier signal output of the WALTx-2 to
the speakers.
All Russound Volume Controls are manufactured using a high-quality
autoformer design which provides long life, excellent frequency response,
no heat build-up, and maximum power transfer from the amplier to the
speakers.
All Russound WALTx-2 volume controls conform to UL Standard 1492 First
Edition, and for Canada Certied to CSA Standard 22.2 No. 1-M94. This
certication assures that your WALTx volume control has been designed
and tested for safety.
Determining the Proper Impedance Switch Settings
The impedance switch 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 amplier. The impedance switch settings can be
determined using the following simple steps:
1. Determine the amplier’s minimum impedance. The amplier’s
minimum impedance is usually found following Wattage and
Frequency Response in the amplier’s specication page of the
manual. It may also be listed on the back panel of the amplier near
the speaker terminals. Impedance is measured in ohms.
2. From Fig. 1, identify the correct impedance-matching chart
according to your amplier’s minimum impedance. There are two
impedance matching charts, one for 8-ohm ampliers and one for
4-ohm ampliers. Choose the chart that describes your amplier. If
your amplier is 6-ohm stable, use the 8 ohm chart.
3. Determine the impedance for each pair of speakers connected to
the amplier by referring to its manual.
4. Determine the total number of 4-ohm pairs of speakers. (Rows on
charts)
5. Determine the total number of 8-ohm pairs of speakers. (Columns
on charts)
6. Follow the appropriate row and column to determine the
impedance switch setting.

Operation Instructions
1. Make sure the amplier/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. Set the button to the ON
position.
3. Set the WALTx-2 volume to maximum (fully clockwise).
4. Turn on the amplier or receiver and select a music source, such as tuner or CD
player.
5. Slowly turn up the amplier or receiver volume and set it to a comfortable
(not maximum) listening level. Be careful not to overdrive your amplier. If the
sound becomes distorted, you have reached the limit of your amplier’s volume
capability and should quickly reduce the volume to avoid damaging your
speakers.
NOTE: If the volume control’s autoformers get warm or vibrate, turn the
amplier/receiver down. If the amplier is driven to this “clipping” state, it and/
or the volume control may become damaged.
6. You can turn OFF the speakers by turning the knob on the WALTx-2 fully
counterclockwise, or by pressing the corresponding ON/OFF button on your
speaker selector.
Installation Instructions
1. 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 installation
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 o the volume
control’s conduit using T-junctions, or by running a
separate line of conduit from the interior of the home. See
Fig. 5 for typical system wiring.
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). 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 nd possible leaks. If the conduit loses
pressure, there is probably a leak.
NOTE: Insucient sealing at any point of the conduit network may cause
moisture to build up inside the WALTx-2 Volume Control. This may cause
malfunction if corrosion occurs.
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.

Wiring Instructions
(Refer to Figure 3 below)
1. Connect the leads from the amplier’s outputs to the connector labeled input.
The wires should stay consistent, left + of the amplier to left + input of the
volume control, observing polarity and identication.
CAUTION: Do not reverse the input and output connections!
CAUTION: A majority of receivers are designed to operate at a rating of
8 ohms. On receivers that oer A and B speaker outputs, both A and B
connections share the same amplier. It is important to note, due to the way
many receivers are wired, that when using impedance matching devices, such
as WALTx-2 volume controls, it is recommended to wire only 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 included outdoor single-gang junction
box. Insert carefully to avoid excessive strain on the connector.
