From the seller

KLARK TEKNIK DN 504 QUAD COMPRESSOR/LIMITER from the factory features balanced XLR inputs and unbalanced XLR outputs with standard pin 2 hot. All four channels have been tested and are working. This unit has been sitting in my living room TV rack for the last 18 years and was mounted in a road case rack from the early to mid 90's until 2006 when I retired. I love the sound of this unit...uncolored signal with a punchy-sounding output. There is a cap missing from the first left-hand knob, and an odd screw on the left side of the face plate that somehow rusted when the other four didn't. There's a paint scratch on the bottom surface of the unit but other than that, it's in excellent condition.
