AtlasIED AT100RM 100W 70V Rack Mount Volume Control

The AtlasIED AT100RM is a professional 100-watt rack mount volume control designed for use in 70V commercial distributed audio systems. Providing up to 27 dB of attenuation, the AT100RM allows installers and system operators to adjust speaker volume levels from a convenient central rack location.

Ideal for commercial paging, background music, and installed sound applications, this rack-mount attenuator offers a practical solution for controlling audio levels in individual speaker circuits without adjusting the main amplifier output.

The AT100RM features a matte black polycarbonate dial scale overlay with adhesive backing, eliminating the need for a separate decorative mounting plate in suitable installations. A matching skirted black control knob provides a professional appearance and convenient manual operation.

For multi-control installations, up to six AT100RM attenuators can be installed on an AtlasIED ATPLATE-052 rack plate, allowing multiple speaker circuits to be controlled from a centralized equipment rack.

100W Volume Control for 70V Distributed Audio Systems

The AtlasIED AT100RM is designed for commercial audio installations using 70V speaker distribution.

With a 100-watt power rating, the attenuator provides volume adjustment for compatible speaker circuits within its rated capacity.

This makes it useful for installations where different areas require independent audio level adjustment.

Typical applications include:

• Commercial paging systems
• Restaurant background music
• Retail sound systems
• Office and administrative buildings
• Educational facilities
• Hospitality environments
• Industrial public address systems

The AT100RM allows operators to adjust the level of a connected speaker circuit while maintaining centralized amplifier operation.

27 dB Total Attenuation

The AT100RM provides 27 dB of total attenuation, allowing the audio level to be reduced from the incoming amplifier signal.

This functionality is particularly useful in distributed audio installations where individual speaker circuits require different listening levels.

For example, a commercial building may need different volume settings for reception areas, hallways, and occupied workspaces.

The AT100RM provides a straightforward manual control solution for these applications.

Rack Mount Installation with Adhesive Dial Scale Overlay

The AtlasIED AT100RM includes a matte black polycarbonate dial scale overlay with adhesive backing.

The overlay provides a finished appearance when the attenuator is installed through a compatible rack panel.

A matching skirted black knob is included for easy operation.

This design makes the AT100RM suitable for both new equipment rack installations and certain retrofit applications.

For existing installations requiring a compatible replacement dial scale, AtlasIED HX23 overlays may be considered where appropriate.

Multiple Volume Controls in One Rack Panel

For installations requiring several independent volume controls, the AT100RM is compatible with the AtlasIED ATPLATE-052 rack plate.

Up to six attenuators can be mounted on one compatible plate.

This arrangement provides a convenient centralized location for adjusting multiple commercial audio speaker circuits.

The rack plate is a separate accessory and should be ordered as needed.
