From the seller

In perfect working condition. Includes original box, manual, and power cable. Besides some rack wear, a screw in the back is jammed (see photo, my fault, it was not the right size) but it's still possible to remove the cover to swap the tubes if needed. Each channel comes with gain, output, HPF, PAD and phase which is really convenient. It's possible to drive the signal at the input stage. Eight channels of warm tube preamplification with optical ADAT lightpipe I/O — perfect for expanding your audio interface by 8 channels. Great on drums, vocals, and full-band tracking. Features: . Eight fully featured Class-A tube mic preamps . Eight channels of ADAT lightpipe digital 24 bit audio I/O at 44.1 or 48kHz . Input gain and output level controls on every channel . Input Pad, Phase flip and Low frequency roll off switches on every channel . Two additional front mounted high impedance instrument line inputs . Eight 1/4-inch TRS balanced outputs
