| Content | LDHPA6 6-Channel Rackmount Headphone Amplifier
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.
The HPA 6\'s main section features a master level control with eight-segment LED metering and 6.3 mm TRS input to mix in an additional source with all channels. The rear panel provides the main stereo inputs on balanced XLR and 6.3 mm TRS connectors and stereo outputs for daisy chaining multiple units.
