Attenuator for 70/25V speaker lines

This Speco mono attenuator mounts in a standard single-gang, high-cube junction box and handles up to 50W. A set-screw terminal accepts wire up to 12-gauge for secure connections. Nine volume steps plus an Off position give local level control for 70V or 25V constant-voltage speaker circuits. The steel wallplate provides a clean, finished appearance.

Installers needing local volume control

It suits commercial audio installers who need a wall-mounted attenuator for a single 70V or 25V speaker run up to 50W. It is not suited for stereo zones or systems requiring remote or automated level management. Buyers needing more than nine discrete steps or a different mounting format should consider other options.

50W mono power rating

The attenuator is rated for 50W maximum on a mono channel, which determines the loudspeaker load it can safely control. Verify that the total tapped wattage of the connected speaker does not exceed this figure. The unit operates on both 70V and 25V line voltages without additional configuration.

Questions about this item

Should I choose the 70V or 25V setting for my speaker line?

The attenuator supports both 70V and 25V constant‑voltage lines; select the setting that matches the voltage your amplifier uses for the speaker circuit.

What does the 50W rating mean when the control is installed in a real system?

It indicates the maximum continuous power the attenuator can handle on a 70V or 25V speaker line without overheating or signal loss.

What wire gauge does the set‑screw terminal accept, and does that limit the installation?

The set‑screw terminals accept up to 12‑gauge wire, so any solid or stranded conductor of that size or smaller can be secured directly.
