3-Band Stereo EQ with Mid Frequency Control

Stereo EQ is a classic 3-Band EQ with Frequency Range Control over the Mid Band.

The HIGH band can boost or reduce the signal by +/-8db at around 5khz to 20khz.
The MID band has a dedicated MID FREQ control that sets the frequency to be changed. It has a pretty narrow range that increases or decreases the singal by +/-5db from 500hz up until 2.2khz depending on the MID FREQ knob setting. The LOW band may change frequencies from 20hz to 300hz by +/-10db.

The signal volume can be set with the INPUT potentiometer.

STEREO EQ has a similar design like the STEREO SUM CHANNEL modules. If you want to have a more detailed EQ control over your mix STEREO EQ is a perfect addition to your STEREO SUM Mixer.
