CEQ

 is an

 analog 3-band Equalizer and Compressor module in 4HP. 

What is a 3 Band Equalizer?

CEQ has 3 equalization controls, which allow the user to 

adjust the tonal balance

 

of the input audio signal: 

high, mid, and low

Each control adjusts the level of a specific frequency range in the audio signal and 
can be used to 

boost or cut

 the level of the corresponding frequency range, 

which allows the user to adjust the tonal balance of the audio signal to their liking.

And a Compressor?

One-knob compressors

 are a type of audio processing tool that simplify the 

process of applying 

dynamic range compression

 to an audio signal. 

The basic principle behind a one-knob compressor is to automatically 

reduce the 

level

 of the audio signal when it exceeds a certain threshold, and then 

gradually 

increase

 the level as the signal decreases. This helps to even out the dynamic 

range of the audio, making quieter sounds louder and louder sounds quieter.

One-knob compressors can be especially 

useful for beginners

 or less 

experienced audio engineers who may not be as familiar with the intricacies of 
more complex compression.
