Atlasied AT100 100W Attenuator 10-step Volume Control

Product Description

The ATLASIED AT100 is a 100-watt, 10-step rotary attenuator designed for 70V distributed audio systems. It provides precise, stepped volume control at individual speaker zones without requiring active electronics or additional amplifier wiring. The unit is built for permanent installation in commercial and light-industrial audio distribution applications. Licensed audio/video technicians and low-voltage electricians are the typical installers. At 100W power handling and 10 discrete attenuation steps, the AT100 gives installers reliable zone-level control in backgrounds music, paging, and intercom systems.

The AT100 is suited for 70V constant-voltage audio distribution systems commonly found in restaurants, retail spaces, offices, warehouses, and similar commercial environments. In a 70V system, volume controls like the AT100 are wired in series with individual speaker taps on a shared distribution line. Each unit controls a single zone or speaker location, allowing independent volume adjustment across a multi-zone installation without affecting other zones on the same circuit. It is sold as a single unit (EA) and is categorized under 70V volume controls.

Key Features

• 100W power handling for use on 70V constant-voltage audio distribution lines
• 10-step rotary attenuation for precise, repeatable zone volume adjustment
• Stainless steel construction for durability in commercial installations
• Passive design requires no external power or active electronics
• Series-wired installation compatible with standard 70V speaker tap configurations

Compatibility

Designed as an OEM-style volume control for 70V constant-voltage distributed audio systems in commercial and light-commercial installations.

Installation Notes

Installation is typically performed by licensed low-voltage technicians or electricians familiar with 70V audio distribution wiring practices. De-energize the amplifier and distribution line before making any wiring connections to the attenuator. The AT100 is wired in series with the speaker load on a 70V line; ensure total zone wattage does not exceed the 100W rating of the unit. Local codes for low-voltage wiring, such as NEC Article 725, may apply depending on jurisdiction.
