The Vaiyer VRSSV4 4-channel speaker selector with volume control is designed for those who want precise, safe, and flexible multi-room audio. Unlike basic selectors, the VRSSV4 gives you individual rotary volume knobs for each channel, so you can adjust sound levels in every room independently. Whether you need soft background music in one area or higher output in another, the VRSSV4 makes it possible without extra amplifiers.

This model also supports dual-source input (AMP A and AMP B). You can connect two amplifiers or receivers and choose which one drives each speaker set. Built on a high-power autoformer design, it provides impedance matching to protect your amplifier, ensuring reliable performance even with multiple channels in use.

Installation is simple: connect the amplifier’s outputs to the AMP A and AMP B inputs on the selector, making sure to follow polarity (+ to +, – to –). Then connect your speakers to the selector outputs the same way. The unit accepts 16–22 gauge speaker wire, and the secure spring-loaded terminals make setup quick and reliable. Compact and durable, the VRSSV4 is perfect for homes, apartments, or small businesses that want professional-quality distributed sound with safe amplifier operation.
