Overview: The Russound WALTx-2 Weatherproof Volume Control
is designed to provide volume control for outdoor speakers, or speakers in wet
locations. The WALTx-2 provides superior protection against moisture from rain,
splash, or humidity. It connects between the speaker outputs of an amplifier and
a pair of speakers.
Mounting Options: The WALTx-2 can be mounted on an exterior
wall or hard, flat surface, as well as directly mounted to a section of 3/4" PVC
Ultra-Match Technology: The WALTx-2's Ultra-Match technology allows you
to easily match the load of multiple speakers to the amplifier impedance without
the need for a speaker selector or other impedance-matching equipment. It
provides impedance matching for up to 16 pairs of speakers per system.
Performance: This in-wall volume control is designed to handle up to
42 watts RMS and 126 watts peak power per channel. The built-in precision autoformers
produce high-fidelity sound with excellent frequency response (20Hz - 20kHz,
+1.0/-0.5 dB at rated power). It provides maximum power transfer from the
amplifier to the speakers without heat buildup.
Volume Knob: The WALTx-2 has a simple clean design with a
simple knob and outdoor wall plate. The knob has 11 steps of volume, plus an off position.
The volume control provides a total of 48 dB attenuation.
Connections: The volume control has two 4-pole screw terminal blocks,
one for the input from the amplifier, and one for the output to a pair of
speakers. The terminals allow you to connect up to 12-gauge speaker wire. The
terminals can be unplugged from the volume control for easier wiring.
Speaker Wire Recommendations: For most applications, stranded 16-gauge
speaker wire is recommended. For runs of over 100 feet, 14-gauge is recommended,
while 12-gauge is recommended for runs of up to 200 feet.
Jumper Settings: Each WALTx-2 has two sets of five jumper pins (five
for the left channel, and five for the right) on the back of the volume control.
The jumpers can be set to 1x, 2x, 4x, or 8x, depending upon the number of
speaker pairs being connected in the system. The jumper sleeves should be
configured the same for all speaker pairs in the system before connecting the
Amplifier Power Ratings: The amplifier should provide a minimum of 20
watts per channel RMS for each pair of speakers connected.
Speaker Impedance: The WALTx-2 is designed for speakers with impedances
of 4, 6, or 8 ohms.
EZB Connecting Blocks: When connecting multiple pairs of speakers to
the system, you will need a Russound EZB-1SC (item #
543EZB1SC) connecting block. The EZB-1SC can connect up to four volume
controls to the amplifier's output. An EZB-2SC (543EZB2SC)
is needed to expand the EZB1SC to another four volume controls.
