Great for schools
We replaced old units with these in our school corridors. The 30W handling is sufficient for our ceiling speakers, and the teachers love having local volume control.

Professional look and feel
Blends seamlessly with our white walls. The build quality feels solid and fire-retardant as described. Great solution for zone control in our retail store.

Easy installation
Our electrician installed three of these in under an hour. They connect easily to the constant voltage line and provide reliable volume adjustment for each room.

Solid performer
Does exactly what it says. No humming or noise when adjusting volume. The switch click is audible but not annoying. Would recommend for small to medium venues.

Perfect for our office hallway
This unit fits perfectly into the standard wall box. The volume control is smooth and the switch is very convenient for turning off the music during meetings. Installation was straightforward.

Good value for money
Works well with our existing 70V speaker system. The sound quality is clear for background music. Only minor issue is the knob feels a bit stiff initially, but it loosened up after a few uses.
Q: Does the switch cut power completely or just mute audio?
A: The switch disconnects the audio signal path effectively muting the speaker. Since the unit is passive, it does not pass electricity to the speaker when switched off.
Q: What size wall box do I need?
A: It is designed to fit standard 86mm type wall boxes, which are common in many commercial and residential installations globally.
Q: Is this compatible with a 100V line system?
A: Yes, this amplifier controller is designed for constant voltage systems, supporting both 70V and 100V lines commonly used in public broadcast setups.
Q: Can I install this outdoors?
A: This unit is designed for indoor use only. It is not weatherproof and should be installed in dry, protected environments like offices, shops, or schools.
Q: Does it require a separate power supply?
A: No, this is a passive volume controller that operates directly off the constant voltage audio line; it does not require an external AC power adapter.
