RDL DB-HA1A Format-A Stereo Headphone Amplifier with User Level Control, Mini Jack Output, RJ45 Input, Black

Deliver clear, dependable headphone audio where it matters most—guest rooms, security booths and monitoring stations. The Radio Design Labs DB-HA1A Format-A stereo headphone amplifier accepts audio and 24 Vdc power over an RJ45 Format-A connection and provides a high-fidelity stereo output on a standard 3.5 mm mini-jack. A front-panel user volume control lets occupants or operators set comfortable listening levels without compromising system settings.

Designed for easy integration, the DB-HA1A features RJ45 loop-thru so installers can daisy-chain receivers with standard twisted-pair cable, reducing labor and wiring cost. Its high common-mode rejection and low-noise headphone amplifier deliver clear audio for security and surveillance monitoring, while the automatic reset fuse protects the system against transient faults. The low-profile Decora® steel panel and absence of illuminated indicators make it ideal for dark environments such as hotel rooms or dedicated monitoring areas.
