Atlas Sound AT35D – Deluxe Deco 35W In-Wall Attenuator 3dB Steps

Product Overview

The Atlas Sound AT35D is a 35-watt deluxe Deco-style in-wall volume control attenuator designed for 70.7V commercial distributed audio systems. It features 3dB-step attenuation for precise volume control and is finished in a Deco plate form factor that mounts in a standard single-gang electrical box. The AT35D is well-suited for commercial applications where individual zone volume control is required at the listening position, including offices, conference rooms, and retail environments.

Product Description

The AT35D attenuator provides local volume control for individual zones within a 70.7V distributed audio system, allowing building occupants to adjust speaker levels without requiring access to the central amplifier or control system. The 3dB step attenuation increments offer meaningful volume changes per step, providing practical control in noisy commercial environments where fine adjustments are unnecessary. Rated at 35 watts, this attenuator handles the output loads typical of single-zone ceiling speaker clusters in commercial spaces. The Deco plate design fits a standard single-gang electrical box, making it compatible with common architectural wallplate formats used throughout North America. Available with a matching white finish, the AT35D blends with standard commercial and residential electrical plate finishes. Its wiring connections use screw terminals for secure, code-compliant connections to the 70.7V speaker line. The transformer-based attenuation design maintains the 70.7V line impedance correctly at each step, ensuring stable operation of the amplifier regardless of the attenuator setting. Installers working in multi-zone commercial systems will find the AT35D a dependable, cost-effective wall control solution that does not require low-impedance balancing or additional matching transformers.
