6.3. De-Essing 

 

A special type of saturation problem often encountered in recording is the sibilant (Ssss) sound of the 

human voice. The solution is frequency-dependent limiting, which is easily accomplished with the unit. 

By inserting an equalizer into the detector patch point and boosting the equalizer at high frequencies 

in the vicinity if the sibilant, the limiter’s detector circuit becomes more sensitive to this particular range 

of frequencies, and so will limit the bothersome sibilants more than other frequencies. 

6.4. Altering instrument texture 

 

Compression can be used to help bring out a lead vocal or instrumental solo in a cluttered mix. The 

compressor is also a great corrective tool when working with singers whose own dynamic control is 

less than perfect. Experimentation is highly recommended. 

6.5. Voice-Over Compression (Ducking) 

 

The unit can be used to reduce music to a background level when an announcer is speaking. The 

detector is connected to respond only to an announcer’s voice. 

6.6. Stereo operation 

 

On the unit, pressing the stereo tie switch combines the detector outputs so that the loudest channel 

controls the limiter action of the other channel. This allows true stereo imaging to be preserved 

regardless of which channel is in gain reduction.
