This is a rotary‑type wall plate volume control for speaker systems with power ratings of up to 100 watts per channel and impedance ratings of 4 ~ 16 ohms. This rotary control can be set to one of twelve positions, including the minimum (off) and maximum volume settings.

The wall plate mounts into a standard (available separately) and has inputs and outputs for one pair of stereo speaker wires (4 input connections and 4 output connections). It can accept speaker wire in sizes from 14 ~ 16 gauge and provides a frequency response range of 35Hz ~ 20kHz (+0/‑2db) at the full power rating of 100 watts per channel.

Please note: This volume control does not include a wall mounting bracket.

When setting up the speaker volume controls, it is important to match the impedance of your speaker system with the load rating of your amplifier. This is done by setting the jumpers on the volume control to compensate for the number of speakers you have in a parallel configuration and the impedance level of the speakers.

If using a single pair of speakers rated at the same load level as your amplifier, you don't need to make any changes ‑ just leave the jumper in the default x1 position. However, if your speakers are of a different impedance level and/or you have more than one set of speakers in parallel, please refer to the following chart as a guide for setting the jumpers on the speaker volume control.

Note that for any speakers wired in series, the overall impedance level is the sum of each speaker. So two 4‑ohm speakers wired in series is the same impedance as a single 8‑ohm speaker.
