The Audion™ 4 amplifier is a 4-channel amplifier with expansion. It has 4 independent controls for compression ratio, compression threshold, expansion threshold, MPO (Maximum Power Output), and compression time constants. It features standard compression adjustment.
- Four-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
