RDL TP-HA1A - Format-A Stereo Headphone Amplifier

The RDL TP-HA1A is a compact stereo headphone amplifier compatible with RDL Format-A twisted pair systems. It receives stereo audio and 24 Vdc power via an RJ45 jack from a Format-A sender, converting the signal to a stereo headphone output on a 3.5 mm mini-jack with front-panel level control.

Delivering 25 mW per channel, the TP-HA1A supports standard headphones with various impedances. Its high common-mode rejection and low-noise, low-distortion performance ensure clear and accurate audio. The front panel is free of illumination, making it ideal for dark environments such as hotel rooms.

Equipped with two RJ45 jacks, the module allows daisy-chaining additional Format-A receivers. The all-metal enclosure mounts to any flat surface, and the base plate design simplifies installation with pre-terminated RJ45 cables.
