The AtlasIED AT35D is a professional 35-watt Decora-style wall volume control designed for 25V and 70.7V commercial distributed audio systems. Combining dependable speaker volume adjustment with a clean, modern appearance, the AT35D is an excellent choice for background music, paging, and installed sound applications.
Featuring a high-quality autotransformer, the AT35D provides 27 dB of total attenuation through ten make-before-break attenuation steps and a positive off position. This allows users to adjust speaker volume locally without changing the main amplifier's output level.
The AT35D includes both white and ivory Decora-style wall plates with matching skirted knobs, making it suitable for commercial environments where appearance is just as important as functionality.
Designed to fit most standard single-gang electrical boxes, the AT35D offers a practical solution for offices, restaurants, retail stores, classrooms, conference rooms, and hospitality facilities.
35W Volume Control for 25V and 70.7V Audio Systems
The AtlasIED AT35D is engineered for commercial speaker systems operating at 25V or 70.7V.
Its 35-watt power rating makes it suitable for compatible distributed speaker circuits with a combined transformer load within the attenuator's rated capacity.
In a typical commercial audio installation, multiple speakers may share a single amplifier. The AT35D allows the volume of a designated speaker circuit to be adjusted independently while other areas continue operating at their selected levels.
This makes it useful for:
- Commercial background music systems
- Distributed paging installations
- Office and conference room audio
- Restaurant dining areas
- Retail stores and shopping facilities
- Schools and educational buildings
- Hospitality and institutional environments
High-Quality Autotransformer Design
The AT35D incorporates a high-performance autotransformer designed to provide reliable volume attenuation with good frequency response and low insertion loss.
This design helps maintain audio quality as the listening level is adjusted.
Unlike conventional low-impedance speaker volume controls, the AT35D is specifically designed for compatible 25V and 70.7V constant-voltage audio systems.
Its 35-watt capacity makes it a practical option for commercial speaker circuits requiring more power handling than a 10-watt attenuator.
Ten Make-Before-Break Attenuation Steps
The AtlasIED AT35D provides ten attenuation steps plus a positive off position.
The make-before-break switching design maintains circuit continuity while the volume setting is changed, helping minimize switching interruptions.
With 27 dB of total attenuation, the AT35D provides convenient control over speaker levels in commercial audio installations.
Silver-plated switch contacts are designed for dependable operation while minimizing unwanted switching noise.
The positive off position allows the connected speaker circuit to be turned off when audio is not required.
White and Ivory Decora-Style Wall Plates
The AT35D includes both white and ivory Decora-style wall plates, along with matching skirted control knobs.
These options allow installers to select the appearance that best complements the room's interior.
The Decora-style design offers a clean alternative to traditional commercial wall attenuators.
The AT35D is particularly useful in visible installations where the volume control should blend with other wall-mounted electrical devices.
Single-Gang Installation with Removable Terminal Block
The AtlasIED AT35D is designed to fit most standard single-gang electrical outlet boxes.
A removable terminal block simplifies speaker wiring and installation.
This allows installers to connect the speaker circuit before securing the volume control in the wall box.
For proper operation, the connected speaker load should remain within the AT35D's 35-watt rating, and the amplifier's output voltage must match the supported 25V or 70.7V system configuration.
