RG Pro 16 Dynamic Processor Expander

• Dynamic Expansion: It makes quiet signals even quieter while leaving loud signals untouched, effectively increasing the difference between soft and loud sounds.
• Noise Reduction: Ideal for cleaning up vinyl records or analog tape by electronically scrubbing out background noise, scratches, and tape hiss.
• Automatic Control: Features automatic attack and release times that adapt to the music, re-controlling dynamics for balanced reproduction.
• Controls: Typically includes controls for expansion level (dB), and often switches for different modes or types of expansion.
• Metering: Large front-panel meters (twin levels) help users visualize the expansion effect.
• Vintage Appeal: Known for its classic look, often with walnut wood sides (PRO-16W) or a metal rack-mount (PRO-16B).
