Operating the Signature Three
To use either equaliser channel, first make sure that all of the boost and cut controls (top row of knobs)
are in their mid or flat positions. You should feel a small click at the mid position which denotes the 'flat',
i.e. no boost or cut position.
Depress the ‘IN’ pushbutton which will illuminate to indicate that the equaliser channel is now in circuit.
Select a frequency via one of the six way selector switches (lower row of knobs).
Turn the boost / cut control (upper row) for that frequency clockwise or anti-clockwise, depending on
whether you wish to amplify or attenuate the chosen frequency.
Repeat to your liking with the other sections / bands.
Note that the frequencies of the four bands of each channel are overlapping. So it’s perfectly possible to
boost a frequency at one band, and also boost the frequency right next to it on another band.
This can result in extreme EQ settings, so use caution because it is quite possible to overload the input
of the device to which the Signature Three is connected.
The
Signature Three is designed to operate at zero gain.
Whatever level is present at the input will also be present at the output, providing all boost/cut controls
are in their mid position. If a large amount of accentuation (boost) is used either on one section or more,
it may be necessary to reduce the input of the device to which the equaliser is connected.
Similarly, if a large amount of
attenuation (cut) is used on one or
more sections, it may be necessary to
increase the input of the device to
which the equaliser is connected.
Alternatively, you could decrease or
increase the output of the device
which is connected to the input of the
Signature Three.
Use of the 'IN' switch allows
comparison of the signal for both
difference in sound and level before
and after the equaliser section.
