Super quality design. Similar to DBX160XT except 2 channels with noise gate. Heavy duty design. Very sophisticated gain ranging design with very accurate calibrated panel controls. Full in/outs for side chain use and phone XLR. Channel calibration within 1 db over 70 db dynamic range!!! Modification to RMS Detector to lessen RMS detector leakage into audio and nicer max compression effect for bigger sound. Low use, all cleaned, minor scuff on top and face. condition #9-
