Description

When you need reliable personal monitoring without dragging a rack around, the ART HP-1 clips right to your belt and handles the job. It accepts a locking 1/4″ or XLR combo input, so it plays nice with either a balanced mono feed or an unbalanced stereo source via a simple switch on the unit. Output runs through a standard 3.5mm jack, and a variable volume knob lets each performer dial in their own level on the fly.

Built into a rugged metal extrusion with heavy-duty jacks, the HP-1 is made to survive the bumps of stage use and the daily grind of studio sessions alike. Power comes from two AA batteries (included), rated for over 40 hours of continuous use, so you’re not swapping cells mid-set. With +9dB of gain and up to 105mW of output power, it has the headroom to push most in-ear monitors and headphones to comfortable, detailed listening levels.
