ons as a general studio equalizer, it is particularly effective
at treating stereo programme material - either at the mixing
stage or during post-production. The special characteristics
of the Optimizer allow you to add weight and punch to the
bass end of a mix or to lift harmonic detail out of the top
end of a mix, without inadvertently adding harshness or
muddiness to the sound. In this respect, the Optimizer can
produce results every bit as dramatic as those achieved using
sub-bass synthesizers or harmonic generators, but without
adding distortion to the original signal.
Where more subtle treatments are required, the
Optimizer’s exploitation of psychoacoustic principles ena-
bles it to significantly improve the focus, tonal balance and
general clarity of detail within a mix, with the bare mini-
mum of processing. This is particularly important when a
client wants to improve the sound of a mix but doesn’t want
to make any significant change to the overall tonal balance.
Even filter Cut/Boost settings of less than half a dB can bring
about significant changes in the perceived quality of the mix
being treated.
The more specialized equalizer modes are most likely to
be used for treating individual signals to create special effec-
ts. There is virtually no limit to the number of equalization
effects you can create through combining the various filters.
Common studio effects such as ‘telephone’ or ‘transistor
radio’ sounds can be set up in moments, while the Notch fil-
ters can attenuate mains hum and rumble, reduce the level
of lighting buzz or even recreate vintage phasing effects.
Proportional-Q and Roll-Off will help processing without any
side effects. You also can use the Notch filters to synthesize a
pseudo stereo signal from a mono source, by placing not-
ches at different frequencies in the left and right channels.
The Optimizer can produce
results as dramatic as sub-
bass synths or harmonic
generators, but without side
effects.
