wow...
best budget 4 channel headphone amp for studio, jam rooms theatre etc, even though it's a 4 channel.. actually there is 12 headphone out, 2 monitor out and many inputs.. at this price i wasn't expecting that much quality but after testing even on full volume there is almost no distortion in the audio, reliable and sturdy, as it is black colour you can also hide them easily and make your desk tidy... thanks mackie for an affordable HA... love it.

Use for band as wired IEMs and also feeds wireless IEMs. I send the feed from the mixer's main or from the mixer's sub/aux into the stereo input and can pan accordingly for each individual output channel (up to 3 input channels for each output channel). The amp is very loud - great job Mackie!
