Portable, Battery-Powered Headphone Distribution Amplifier

The compact HX-3 Headphone Distribution Amplifier is the perfect accessory to quickly provide three high-performance stereo headphone feeds with individual level controls from line-level sources. The HX-3 can produce very high headphone levels with extremely low noise and distortion.

Great for radio, television, film, and music production applications, the battery-powered HX-3 accepts balanced XLR line-level inputs or unbalanced 1/4-inch and 1/8-inch stereo inputs. Its 1/4-inch loop-out can connect multiple HX-3's for additional headphone outputs. Headphones are connected to panel-mounted 1/4-inch stereo connectors.

The HX-3 has a durable aluminum chassis to withstand the punishment of field and studio environments. The unit is powered by inexpensive batteries (two-AA) or external 5-18 VDC.

The HX-3 can add headphone outputs to the 442, 302, MixPre, MM-1, and USBPre.
