120-Watt Slider Volume Control

This 120-Watt slider volume control manages speaker levels with audiophile sound quality and virtually no high-end or low-end roll-off. A non-shorting design prevents amplifier damage during adjustment. The 12-position switch provides 36dB total attenuation across Off, two 6dB steps, seven 3dB steps, and full-on settings. It suits whole-house audio zones or single-room installations.

Solderless Terminals and Inserts

Color-coded, right-angle, solderless speaker terminals allow quick top termination without special tools. The package includes white, almond, and ivory plastic inserts and knobs to match common wall-plate finishes. A standard single-gang electrical box is required for mounting; verify depth before starting. Wiring errors such as reversed polarity or loose strands are the most common installation issues.

Amplifier and Impedance Check

Confirm your amplifier can drive the connected speaker load with this control in the circuit; the non-shorting design protects the amp but does not change impedance requirements. Ensure speaker wiring reaches the wall-plate location with enough slack for the right-angle terminals. The 0.72 weight figure refers to the packaged unit, not a mounting specification.

Questions about this item

How can I verify the volume control is attenuating correctly after installation?

Check each of the 12 positions from Off through the two 6dB steps and seven 3dB steps to full on; the non-shorting design protects your amplifier while you test.

What comes in the box and what must I supply myself?

The package includes white, almond and ivory inserts and knobs plus color-coded right-angle solderless terminals; you only need speaker wire and a standard single-gang wall box.

Which attenuation range suits my system — 36dB total with 12 positions?

The 12-position switch gives Off, two 6dB steps, seven 3dB steps and full on for 36dB total attenuation; choose this model when you need fine 3dB increments up to that range.
