LD Systems HPA 6 Headphone Amplifier, 6-Channel

The LD Systems HPA 6 is a highly flexible 1U 19” rack format headphone amplifier with 6 fully independent channels and comprehensive features for a wide range of professional audio monitoring applications. Each channel provides a 6.3 mm TRS headphone output on the front panel with level control, mono/stereo switching, discrete left/right muting and a 6.3 mm TRS Aux input with Main/Aux balance control for mixing in further signal sources. Four-segment LED meters permit visual output level monitoring, and two 6.3 mm TRS outputs per channel on the rear allow for connecting a total of 18 headphones.
