Mackie HM-800 8-channel headphone amplifier provides versatile headphone amplification for artists, musicians, and engineers monitoring through headphones in live stage applications and home, project, commercial, and mobile-recording studios. It features two stereo main outputs via four 1/4″ jacks and sixteen 1/4″ TRS stereo headphone outputs – two per channel – fed by a customizable blend of inputs.
Two stereo main inputs via four 1/4″ jacks can be combined with a per-channel 1/4″ stereo aux input. Each channel offers stereo/mono mode switching, input selection, and output level adjustments. 7-segment LED meters display main input and per-channel output levels.
