LD Systems HPA 6 19-inch Headphone Amplifier

The LD Systems HPA 6 headphone amplifier features six fully adjustable channels and can be mounted in a 19-inch rack to build a professional set-up. Each channel is equipped with a front-fitted TRS jack output, a TRS jack input, an independent volume control, a mono/stereo switch and a left/right mute control, where the channel inputs can be used to mix extra signals in with the master signal. Around the back of the HPA 6, there are two extra TRS jack outputs per channel, setting you up with a total of 18 headphone outputs.
