Pair of Collins 356E I recently racked for a client. These have all the factory options brought to the front panel - Mode switch, Threshold/Ration control, and posts for threshold voltage measurement. In addition, the client requested high pass filtering for the side chain circuit and there is a three position selection for this as well as a compressor off position. The release switch includes 5 positions that cover the factory settings plus additional positions that offer different attack and release times covering a much wider range. There is also link switch for stereo operation. T-Pads for input and output attenuation.
