This slider control can be set to one of twelve positions, including the minimum (off) and maximum volume settings.
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. This is a slider‑type wall plate volume control for speaker systems with power ratings of up to 50 watts per channel and impedance ratings of 4 ~ 16 ohms.

The wall plate mounts into a standard single‑gang, low‑voltage wall bracket (not included) and has inputs and outputs for one pair of stereo speaker wires (4 input connections and 4 output connections).
