This looks like the input section of a VR or VRL console- mic pre is nothing special but OK - the gates are decent and the comps can sound pretty nice on rock guitars etc- functional rather than exciting. - Looks like it is actually pulled from a channel though rather than a V-Rack so it would be odd getting it powered up on it's own... but possible I'm sure. Problem with all VR stuff is if a switch breaks they are irreplaceable.
Hope that helps a little.
