From the seller

2 (two) Orban 622B's (that's 4 (four) channels of 4-band parametric EQ) are for sale in this listing. These legendary EQ's have served at many concerts in the S.F. Bay Area. Every knob twists smoothly through it's full range of motion, none are bent. Every switch throws confidently with a distinct click/thud. There is light corrosion/oxidation/rust on some of the terminals as seen in the photos. The power cord jacket on one of the units is nicked (as seen in the picture) but does not short. Both power cord plugs are missing the ground prong. Removing this prong (known as "lifting the ground") was a common practice back in the day to minimize ground loop hum in the audio feed. It was understood to be safe as the chassis were grounded through the rack rail. Both were rack mounted.
