RDL DS-HPA3 Series 3.5W Wall-Mounted Audio Power and Headphone Amplifier, Stainless Steel

Optimize audio for surveillance, security and paging with the Radio Design Labs DS-HPA3 wall-mounted audio power and headphone amplifier. This compact stainless-steel module combines a 3.5W Class D speaker output and a front-panel mini-jack headphone amp, giving technicians and operators clear, immediate audio access while allowing the speaker to be muted automatically when headphones are connected. The DS-HPA3 accepts balanced line-level inputs (unbalanced compatible) and drives 4 or 8 ohm speakers, making it easy to tie into existing PA, monitoring and security systems.

Engineered for professional environments, the Class D design provides excellent audio clarity with negligible heat, while the 24 Vdc operation and detachable terminal block simplify wiring and power integration in racks, control rooms or field enclosures. Recessed switches let installers set input sensitivity and headphone mute before mounting for a clean, tamper-resistant installation. Ideal for surveillance monitoring stations, guard booths, or small paging endpoints—specify the DS-HPA3 to add reliable, serviceable audio to your security or monitoring deployment.
