I wanted the rackmount equivalent of the Mini Amp800, and this was it. Two main inputs, independent volume controls for each on all outputs, and aux inputs on every channel.
This adds added possibility of hooking aux inputs on some of the channels, requiring hooking-up the headphones to a different output, but with 8 channels, it leaves me with the possibility of also using this unit as a main monitoring unit on small gigs, guys use either corded headphones or BT transmitters and headsets, with the aux inputs hooked to different mixer outs and mixes...
I'm loving it. I just wish Behringer also had a 6~8 channel model with both two mains and bass/treble EQ on each channel.
That said I believe this unit provides the basics for cheap multi-monitoring outs, and that's already quite good at this price point.
