RP533
Studio Tube Multi-Processor
Bellari is a division of
ROLLS Corporation

Salt Lake City, UT 84107
The Bellari RP533 is a versatile studio tool for signal
amplification, compression and spectral enhance-
ment - all through the use of innovative tube circuitry.
The unit features our highly acclaimed mic preamp
circuits for pristine preamplification. The compressor/
limiter section contains new, carefully designed
dynamic gain reduction circuitry for subtle, natural
compression. Finally, the sonic exciter section of the
RP533 restores material clarity and adds distinction
and character to the final signal. The meter can be
switched in the circuit path to show the input level,
output level, or compressor gain reduction.
FEATURES:
• Warm, silky tube preamplification
• Smooth, natural compression
• Sonic Exciter, frequency enhancement
• All tube gain circuitry with proper high-voltage plate
voltages
• Transformer balanced input
• 1/4” and XLR inputs and outputs
• Calibrated metering - switchable in the circuit path
• +48 Volt Phantom Power
• Side Chain for direct access to the compressor's
detector circuits
