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.

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.

FEATURES:
• All tube gain circuitry with proper high-voltage plate
  voltages
• Solid state input and output buffering only
• 1/4” and XLR inputs and outputs
• Calibrated, accurate meters
• Smooth, lively tube sound
• Side Chain for direct access to detector circuits

WHY A TUBE COMPRESSOR / LIMITER?
With the recent explosion of the digital recording
world, tube based preamps and signal processors
have become popular to overcome the inherent
