Quam Nichols Company QC10 Attenuator 70V Volume Control

Product Description

The QUAM NICHOLS COMPANY QC10 is a 70-volt attenuator with embossed volume positions, designed for use in distributed audio and commercial sound systems. Attenuators in this category allow field technicians and audio system installers to set and control speaker volume at individual zones without returning to the central amplifier. The embossed position markings provide tactile and visual confirmation of each volume setting, improving reliability during installation and routine service.

This attenuator is suited for 70-volt distributed audio installations common in commercial, institutional, and light industrial environments. These systems are standard in facilities such as schools, offices, retail spaces, and warehouses where multiple speakers are driven from a single amplifier across long cable runs. The QC10 is sold individually and is intended for integration into ceiling, wall, or surface-mount speaker assemblies.

Installation Notes

Installation of 70-volt attenuators should be performed by a qualified audio systems technician or licensed low-voltage contractor. Disconnect and de-energize the amplifier before wiring the attenuator into the speaker line. Follow applicable local low-voltage wiring codes and manufacturer wiring diagrams for proper line-level connection. Verify polarity and impedance matching at each zone before restoring power to the system.
