The Behringer MiniAmp AMP800 4-channel headphone amplifier is an easy and low-cost way to power up to eight sets of headphones. Each headphone channel supports two sets of headphones and gives you the choice of two input sources, with pan and input level control over each source. And if you need to power more than eight sets of phones, use the parallel link output to cascade your source signals to an additional headphone amp. If you need to power multiple sets of headphones without sacrificing control over your audio, you can't go wrong with the Behringer MiniAmp AMP800 headphone amplifier.
