removed without upsetting the rest of the frequency spectrum, or a single frequency
needs to be boosted to create a particular unique sound. A proven technique for
identifying frequencies is to set the Q control to its minimum (narrow) position, apply
a reasonable amount of boost in that EQ band, and then sweep the Frequency
control around until the problem (or desired) frequency is found (since boosting will
make the frequency prominent). Cut (rather than boost) can then be applied if the
frequency is troublesome, and if necessary the Q can be widened to take out a
broader band of frequencies.
Intermediate Q settings, say 1 to 3, are generally used to enhance or reduce a
broader range of frequencies, typically to make an instrument or vocal stand out - or
recede - into the mix. Finally, low Q values (down to about 0.7 on the 5052, which
roughly corresponds to 1.4 octaves) provide gentler contouring, or “sweetening” of
the response.
4.26 Shelving EQ.
The LF and HF sections offer either ‘peaking’ or ‘shelving’ equalisation by means of
a dedicated switch. In peaking mode the EQ band will cut or boost a fixed band of
frequencies either side of the selected centre frequency (a little like a parametric
section but without a variable Q control) – in this mode the Q is fixed at 1.5. In
shelving mode the band will process any frequencies below the selected frequency (in
the LF band) or above the selected frequency (in the HF band) with a slope of
12dB per octave. Shelving EQ can be used to “roll-off” low or high end frequencies
or to boost all frequencies above or below the one selected by the variable
frequency control. This can be effective for “warming up” the low frequencies or
adding brightness or “air” to the top end frequencies.
4.27 EQ On.
The ‘EQ On’ switch allows the EQ section to be activated or bypassed for
comparison of the equalised and original, unprocessed signal.
4.28 EQ Pre.
The ‘EQ Pre’ switch places the equaliser ahead of the compressor section in the
signal path. This enables more flexibility in sound, since the compressor will become
more sensitive to any frequencies that have been boosted by the EQ section. The
effect may be compared by toggling the EQ Pre switch.
