The RP583 is a clean, delightfully warm sounding  
compressor/limiter designed for a variety of uses. It  
can lightly compress a vocal track, or an overall  
program mix, or it can act as a ceiling for the audio  
allowing only a designated level of signal pass. All  
this is accomplished via optical isolated gain reduc-  
tion and tube circuits to maintain a pristine full-  
bodied sound.The RP583 has all the necessary  
features like analog metering, variable threshold,  
ratio, attack and release times, and a stereo link  
switch which combines the channels and makes  
Channel Two the master.  
harshness and brittle sound created by the recording  
medium.Tube based compressors have the added benefit  
of a natural, even harmonic compression which adds a  
smooth and warm characteristic to the sound.  
The Bellari RP583 provides all the compression param-  
eters necessary for complete control over the dynamic  
process, and it does it all with new and innovative tube  
circuit technology.
