Great outdoor volume control

Written by: Jack from Houston, Texas on August 29, 2015

Crutchfield Customer Review (What's this?)

Works great. It was nice to have an outdoor volume control for our outdoor speakers. Although I can control the volume inside the house or with my iphone, I'm usually wet when getting out of the pool or may not have the phone near me, so having this is really useful. I gave it 4 stars, b/c it's a bit pricey. Another retailer has similar devices for cheaper, although I can't comment on the quality of those. The quality of this product although expensive has been quite good.

Pros: 1) seems of good quality. 2) works well.

Cons: 1) expensive compared to some other similar devices on other websites. 2) Mine didn't come with screws to mount plate or to wall. You'd think since it's so much compared to other similar products, it would come with screws. Not to big of a deal, but it's the principle of it all.

Product Research


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 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.

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.
