Monoprice Inc. 138176 60-Watt Volume Control with A/B Switch

60-Watt Volume Control with A/B Switch

This impedance-matching volume control lets you connect multiple speaker pairs to a single power amplifier or receiver. It presents a safe overall impedance to the amplifier while giving you independent level adjustment. The unit handles amplifiers rated up to 60 watts and mounts in a standard single-gang low-voltage junction box.

A/B zone switching for two speaker sets

The built-in A/B switch selects between two connected speaker zones fed from one source. This replaces the need for a separate speaker selector when you only need to alternate between two rooms or pairs. The jump is worth it when you want simple zone control without adding a multi-zone amplifier or matrix switcher.

Check amplifier power and wiring before ordering

Verify that your amplifier or receiver does not exceed 60 watts per channel into the load this control presents. Confirm you have a single-gang low-voltage box or bracket at the planned mounting location. Ensure your speaker cable runs are terminated for the volume control's terminals and that you only need two zones, as this unit does not support more than an A/B pair.
