BEHRINGER HA400 AMPLIFIER FOR 4 HEADPHONES

You can use this super-compact stereo headphone amplifier with virtually any type of headphones. For example, you can allow 4 different people to listen to the master mix in your studio while recording is in progress, and each listener can determine his or her own volume level using the dedicated output controls. The MicroAmp HA400 contains 4 high-power stereo amplifiers that maintain the highest sound quality, even at maximum volume levels. Ultra-low noise 4580 amplifiers are included for exceptional audio performance - these are the same op-amps found in "full-size" audio equipment. A 12 Volt power supply is included.
