compressor or limiter. Placing the graphic equaliser after dynamics could cause the compressor or limiter to react to frequencies not audible in the output, creating unusual undulations in volume not associated with the program material.

The second reason for placing the graphic equaliser before dynamics occurs where the dynamics processor is being used to safeguard PA systems or digital recorders. As the equaliser can create changes in volume (both with EQ and input gain), placing it after a limiter or compressor, may cause increases in gain beyond safe limits.

4.2. A word of caution

Sadly, graphic EQs can’t cure every problem you’re likely to encounter as an engineer. Not only that, but it’s highly unlikely that you’ll ever get a truly flat room response without calling in some builders. Consequently, a compromise must be struck between technical perfection, sonic quality and, very often, the time taken to reach such a balance.

There are three things worth remembering when using your graphic EQ: Avoid extreme settings unless for an effect; they will most likely sound unnatural and may exacerbate balance problems. Boost tends to sound more obvious to the ear, so cut troublesome frequencies rather than boosting nice ones. And finally, remember that while the legend and calibration markings on your EQ231G-SP are a useful guide, they are just that, a guide so be sure to trust your ears.
