Bogen ATP35 35W Attenuator with Bypass for 25V/70V Speaker Line, Mounts in Standard Single or Double Electrical Box

Take direct control of local speaker levels without disturbing system-wide amplifier settings. The Bogen ATP35 pro audio controller (35W attenuator) delivers reliable, tamper-resistant volume control for 25V and 70V speaker lines, ideal for paging, background music, security, surveillance and monitoring applications. Install the ATP35 in a standard single or double electrical box and use the rotary control’s 10 attenuation steps (plus Off) to set repeatable, incremental level reductions. When an important announcement or alarm must override local settings, the built-in bypass accepts 9–30V DC between D+ and D- to instantly restore full-volume output to the speaker circuit. With pluggable screw terminal connections, compact 4.8" x 4.8" housing, and a 2-year limited warranty, the ATP35 reduces installation time and ongoing maintenance costs for integrators and facilities managers. Specify the Bogen ATP35 for schools, retail, corporate, and security-centric projects where dependable local control and emergency override are essential — contact sales or add to your bill of materials today.
