The white D-HA1A Format-A Stereo Headphone Amplifier from RDL is a two pair receiver and audio headphone amplifier compatible with RDL Format-A twisted pair products. Each unit receives stereo audio and 24 VDC power through a rear-panel RJ45 jack fed from a Format-A sender. The left and right audio signals received on pairs B and C of the twisted pair cable are amplified and fed to the left and right channels of the output 3.5mm mini-jack.
The front panel provides the headphone output jack and a single-turn user volume control. There are no illuminated indicators that could be distracting in dark locations, such as a hotel room. The audio input circuits feature very high common mode rejection and a high quality stereo headphone amplifier for superior audio fidelity and low-noise performance.
The amplifier is equipped with two Format-A RJ45 jacks. Either jack may be used as the input. The other RJ45 may be used to connect an additional amplifier or other Format-A receiver. Installation is simple and economical. A standard twisted pair cable is used to connect a Format A sender to the amplifier.
The unit features automatic fused power, hum rejection, low noise, and low distortion for designers and installers looking to work with twisted pair products. The D-HA1A is ideally suited to guest room installations with bedside and restroom listening stations. The input is fully compatible with all RDL Format-A senders
