The ha11.1 from Music Hall is a headphone amplifier. It is designed to provide a detailed, low-noise sonic experience to audio monitored through its frame. Its extruded-aluminum chassis wards off magnetic interference while simultaneously protecting the electronics inside.
The ha11.1 sports two stereo pairs of RCA jacks—one for inputs, the other for outputs. Located on the front of the unit are a 1/4" stereo headphone jack and a volume pot. This unit includes an external power supply and is compatible with most headphones.
