The Audion™ 4 amplifier is a 4-channel amplifier with expansion. It has four independent controls for compression ratio, compression threshold, expansion threshold, MPO (Maximum Power Output),and compression time constants. It features standard compression adjustment.
- 4-Channel Wide Dynamic Range Compression with Dynamic Contrast Detection™
- Patented Adaptive Feedback Cancelling
- Layered Noise Reduction™
- Expansion – Gain Reduction for Low-Level Sound
- Output Limiting – Wide Band Output Limiting (MPO) with Adjustable Thresholds
