The DPR-404 is a compact and professional four channel compressor and deesser. Based on the well established BSS subtractive gain reduction principle, it offers you four independent channels of high quality, musical compression and high frequency de-essing, with the minimum of operator controls. Designed to be quick and easy to operate by both skilled and novice engineers alike, it makes a compact economical alternative to the fully featured DPR-402 model. The DPR-404 is the natural complement to the well established DPR-402 unit and will find many applications within professional audio where ease of operation is considered important along with lower cost without sacrifice to quality and musicality. Some of the important features to be found on each channel of the DPR-404 are: 30dB of gain reduction using BSS proprietary subtractive approach. Fully adjustable soft knee ratio up to 20:1 hard limit. Automatic adjustment of time constants with two user definable ranges. Output gain adjustment control with LED clip indicator. BSS proprietary activity meter showing below threshold signal level, gain reduction and usable range. Bypass in/out switching with LED indicator. Independent high frequency deesser threshold control and tuneable filter allows selective de-essing simultaneously with compression. Twin LEDs show de-ess activity. Link switching allows adjacent channels to be linked for accurate stereo working. One DPR-404 can be selected to process two stereo channels, or one stereo channel and two independent mono channels, or four independent mono channels. Compressor side chain insert on rear panel 1/4" RTS jack. Electronically balanced inputs and outputs with optional transformer balancing.
