In the shop we have a lightly used Behringer Ultragraph Pro Rack EQ!

This unit is working and does not include original box. 

Here's more from Behringer:

Professional audio engineers have known for decades that a good EQ makes all the diff erence in how a performance is perceived. Although multi-band graphic equalizers have been around for a long time, they have changed very little… until now! The ULTRAGRAPH FBQ-PRO FBQ3102 takes the graphic equalizer a giant leap forward technologically, providing robust feature sets and our proprietary FBQ Feedback Detection System – at a price that makes them a must-have for anyone who records or operates a live sound system.

• Professional 31-band stereo graphic equalizer for live and studio applications 
• Revolutionary FBQ Feedback Detection system instantly reveals critical frequencies and can also be used as audio analyzer 
• Dedicated mono subwoofer output with adjustable crossover frequency 
• Additional sweepable high and low-cut fi lters for each channel remove unwanted frequencies, e.g. floor rumble, hiss etc.
• Highly accurate 12-segment LED input/output metering and input gain controls for easy level setting 
• Ultra-low noise audio operational amplifi ers for highest signal integrity 
• Relay-controlled hard-bypass with an auto-bypass function during power failure (failsafe relay) 
• Servo-balanced inputs and outputs with ¼ " TRS and gold-plated XLR connectors 
• Shielded toroidal power transformer for ultra-low noise performance
