Helios Helios In-Wall Volume Control

The impedance matching stereo volume control is a common concept in whole-house audio installation. It is a full range volume control that can be adjusted to meet the requirements of your installation. With a simple change to the impedance matching switch, you can safely connect multiple pairs of speakers to a single amplifier (or receiver). Refer to the charts provided in this manual to determine how to set the switch to ensure the proper impedance level is sent to your amplifier.
