Description
A 4 channel compressor with high frequency de-essing.
Each channel includes:
- Threshold control
- Below threshold metering
- Ratio control
- A gain reduction meter
- A clip LED
- Gain control
- Linking
- High frequency de-esser.
Attack and release time constants are automatically and continually regulated by dynamic and harmonic content of program material.
The unit features electronically balanced inputs and outputs.
