OPERATION

How do you use a parametric equaliser? The answer could not be sim-
pler, merely listen! This might sound obvious but only a parametric
equaliser with its continuously variable control of all parameters allows
you to zero in on exactly the sound you want.
Try the unit out with programme material. Switch all but one section
out on one channel and try out the following on the section you have
left switched in. Set the bandwidth control central and apply about
12dBs of boost.
Sweeping the frequency control you can now easily select the frequen-
cy you wish to equalise. once you have found the centre frequency the
amount of boost or cut can be varied and the range of the equalisation
can be altered with the bandwidth control.
Wide bandwidth settings give conventional sounding equ alisation. Nar-
row bandwidth boost produces a ringy effect, whilst narrow bandwidth
cut removes a particular frequency without being audible in the pro-
gramme.
Phasing effects are produced when sweeping the frequency controls,
the type of effect produced depending on both the equalisation and
bandwidth control settings.
The input gain control is used to compensate for overall changes in
level due to equalisation. The overall In/Out switches bypass the chan-
nel gain controls and therefore allow either direct comparison of
straight and equalised programme or switching in of pre-set equalisa-
tion during mixdowns etc.
