What U73b Compressor does
Compression is set with program-dependent and fixed release times, three of each to choose from, and an additional high-pass filter switch moves the sound between vintage and modern behavior. External sidechain input is supported, and an optional automatic output level control is available.
Key features
- Tube circuit model. The circuit of the original broadcast unit is modelled to reproduce its analog tube behavior.
- Release time selection. Three program-dependent and three fixed release times can be chosen, so the recovery can follow the material or stay constant.
- High-pass filter switch. A switch adds a high-pass filter that changes the character between a vintage and a modern sound.
- Sidechain input. An external sidechain input lets the compressor respond to a signal other than the one it processes.
- Automatic output level. An optional automatic output level control adjusts the output gain after processing.
- Crack, keygen and serial variants. Queries often pair the name with keygen, serial key and iLok emulator, and a working serial is the string most often typed.
