Rives Audio PARC Room Correction EQ

I have two black Rives Audio PARC equalizers with sequential serial numbers (103.0204, 103.0205) for sale that were recently pulled out of a very clean job site. They both pass audio flawlessly on both RCA and XLR connections, and all front panel functions are without issue. I have not been able to test the Link and Comm ports, but have no reason to believe they don't function. Owners manual is a PDF. For those who are not familiar, the PARC is a stereo, 3-band, parametric equalizer for use in correction of low-frequency room modes. The audio path is entirely analog, and features both balanced and unbalanced inputs and outputs. Accepted input voltages are 100, 120, 220, and 240 VAC, at 50 or 60 Hz. Each of the bands is adjustable between 16 and 350 Hz, independent per band and channel, with 0-18 dB of attenuation at Q factors between 1 and 11. Asking price is per unit. Feel free to ask me any questions you may have, and I will certainly do my best to answer. Thanks!
