This is an RS5700 4 Channel Module from a Soundcraft K1 mixer.
Item is in well used condition - grubby with scuffs, scratches. A couple of the rotary dial stems are slightly bent/misshapen.
There are no caps for the faders/knobs. Item is exactly as per photo's.
We have no way to test - sold As Is for Spares/Repair/Restoration.
