Russound WALTX-2 126W WEATHERPROOF VOLUME CONTROL.
WALTX-2 - Weatherproof Stereo Volume Control with Impedance Magnification
The WALTx-2 is a weatherproof 126-watt volume control in a surface-mount PVC enclosure. It connects between the speaker outputs of an amplifier or receiver and a pair of speakers.
Designed for outdoor or wet locations, the WALTx-2 can be mounted on an exterior wall or other flat surface, as well as directly on a section of 3/4" PVC conduit. The WALTx-2 provides convenient control of your speakers with superior resistance to moisture from rain, splash, or sauna.
Using Ultra-Match technology, the WALTx-2 allows installers to easily match the load of multiple speaker pairs to the amplifier impedance without the need for a speaker selector or other impedance-matching equipment.
All Russound volume controls are made with precision autoformers for high-fidelity sound, excellent frequency response, no heat buildup, and maximum power transfer from the amplifier to the speakers.
Russound ALTx-series volume controls conform to UL and CSA standards to assure that they’re designed and tested for safety.
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 conduit.
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 speakers.
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.
