HB-HD6
Headphone Distribution Amplifier
The HB-HD6 is a professional studio headphone distribution amplifier designed for broadcasting station and recording studio. It provides up to six channel headphone outputs with individual control. Each of the six channels can drive up to three set of headphones for a total of eighteen at the same time. The HB-HD6 also provides Parallel Thru main outputs which allows user to daisychain more headphone amplifiers together.
The HB-HD6 offers a stereo auxiliary input that allows user to sum an additional signal with the MAIN INPUT signal connected at the rear panel. An input mix control and a mono/stereo selector are on the front panel.
EASY OPERATION
The front panel is laid out clearly with six 6.3mm stereo headphone jack outputs with individual volume control and MUTE switch. A clip LED indicates that the headphone output level is too high and should be reduced in each channel. A rotary control can adjust the MASTER LEVEL from -9dB to +9dB with two clip LEDs indicate the left / right master input signal.
The rear panel is equipped with two COMBO inputs to accept XLR or 6.3mm TRS jack balanced line level signals, and two XLRs providing simultaneous line level thru outputs. Two stereo headphone outputs parallel through the front output on each channel.
FEATURES
