LD Systems HPA 6 - 19" 6-channel headphone amplifier
LD Systems HPA 6 is an extremely flexible headphone amplifier in a 1U 19“ rack format with 6 fully independent channels and extensive features for a wide range of professional audio monitoring applications.
Each channel features a 6.3 mm TRS headphone output on the front panel with level control, a mono/stereo switch, separate left/right muting, and a 6.3 mm TRS Aux input with Main/Aux balance control for blending in additional signal sources. Four-segment LED meters enable visual monitoring of the output level, and two 6.3 mm TRS outputs per channel on the rear allow you to connect up to 18 headphones in total.
The HPA 6 main section includes a master level control with eight-segment LED metering and a 6.3 mm TRS input for mixing an additional source into all channels. The rear panel houses the main stereo inputs on balanced XLR and 6.3 mm TRS connectors, as well as stereo outputs for daisy-chaining multiple units.
