ART HeadAmp 4 Channel Stereo Headphone Amplifier ARTcessories w/ Power Adapter

I used this unit in my home studio for about 1 year. It’s in perfect condition. No box or manual. Power adapter included. The HeadAmp4 from ART is a high-quality four-channel headphone amplifier great for band rehearsals, home theater, or any application where you need multiple headphone connections. The stackable metal unit has both 1/4" and 1/8" input connectors for receiving a stereo signal from a mixer, tape deck, iPod, etc. Each of the four output channels also has a 1/4" and an 1/8" connector so you can connect up to eight of your favorite set of headphones or in-ear monitors. The front panel has four large knobs for controlling the level of each channel, and a green power LED lets you know that power is reaching the unit. For high-quality, low distortion audio monitoring.
