The ATLAS Sound LP AT100-RM is a professional, rack-mountable passive volume control designed for centralized level management in 70V/100V constant voltage or 8-ohm low-impedance distributed audio systems. This unit provides a robust, continuously variable attenuation control for a single audio zone or feed, allowing system operators or technicians to make precise level adjustments from a standard equipment rack location rather than at a wall plate. It is engineered to handle the power levels typical of commercial background music, paging, and sound reinforcement systems, with a power rating of 100 watts, making it suitable for larger zones or systems with higher output requirements.

The attenuator features a high-quality, audio-taper rotary potentiometer that offers smooth, glitch-free adjustment across its entire range, from full output to complete attenuation. Its passive design requires no external power, ensuring reliability and simplicity in installation. The unit is constructed with a durable metal chassis and mounts in a single rack unit (1U) space, featuring a front-panel control knob and a straightforward connection terminal block on the rear for input and output wiring. This centralized control approach is ideal for equipment closets, control rooms, or rack locations where master level control over a specific feed—such as a paging channel, music source, or zone output—needs to be readily accessible and adjustable.

As a component within a larger commercial audio system, the LP AT100-RM provides a dependable and professional method for gain staging and final output trimming. Its rack-mount form factor integrates seamlessly with amplifiers, DSP units, and other rack-mounted equipment, contributing to a clean and organized installation. By offering high-power handling in a passive, no-frills design, this attenuator serves as a practical and essential tool for system integrators managing the final output levels in commercial audio installations.
