The HDA600 is a full featured, six-output stereo headphone distribution system. Parallel balanced XLR and TRS cue and stereo line inputs allow easy loop-thru and connector flexibility. A mic/line cue input is adjustable and selectable into left, right or both internal distribution busses mixed with the stereo line feed. Clipping LEDs monitor cue and line inputs. Six independent, 100mW, high compliance stereo headphone drivers are fed from either the internal distribution busses or from individual rear TRS connectors configurable as stereo unbalanced or mono balanced inputs. Signal presence LEDs monitor each input.
