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.
