The BSS DPR-404

The DPR-404 is a compact and professional four channel compressor and de-
esser. 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
