No rack, a mono, 2 stereo, one in / out tape, all very light and compact.
Not to just a bass and treble EQ on the edge mono (no EQ ...). 100% of basic.
I used to controller the size of my monitor assets and the return headphone musician.

UTILIZATION

Very simple: no need for manual, I did not read.

SOUNDS

Well the preamp is useless to me except as the Talkback.
I never recorded with, it is still down the audio chain.
EQ zero at zero. Not too many breath.

OVERALL OPINION

The least: There's just something I was not able to simply adjust the volume independently headphones / hands out to (the headphone is conditioned by the hand out).
The only solution is to put back on the DAW in RCA Tape in and switch on 1 or 2 switches ... but hey I came out in Jack symmetric sound card and j'e do otherwise.
The more .... I seek.
Sound quality really disappointing. The knobs crack after a few months of use, and in addition, the stereo is not observed when the volume knobs are low .... so it's very average all for the routing of monitoring.
I will change as soon as my priorities have changed ...
