The ATI AUDIO HDA600 is a rugged six-output stereo monitoring system in a one rack-space package with an internal AC power supply, that provides excellent performance driving a wide range of typical 32 to 600 Ohm high-efficiency stereo headphones to levels near 120dB SPL. The HDA600 features both stereo program input plus a mono cue input driving six stereo headphone output drivers. It is made to bridge both balanced and unbalanced program input lines with individual left and right XLR and .25" TRS input connectors. The spare connector set may be used to loop-through the input signal to additional HDAs. Inputs are electronically balanced but will operate properly when an unbalanced 1/4" plug is inserted. The HDA600 includes an internal bi-polar power supply that will operate at 115 or 230V AC by changing internal jumpers.

These headphone amplifiers provide complete a monitoring solution for on-the-air studios, line remotes, houses of worship, production rooms, learning centers, home studios, or state-of-the art recording studios.
