3. Operating Instructions
3.1. Controls
1.
EQ faders
allow high-resolution control over EQ gain at 31 ISO frequencies.
The frequency is indicated on the front panel, as are the amounts of cut and
boost, between –12 and +12 dB. Each fader has a centre detent, which allows
you to quickly return it to its inactive (0dB) position.
2.
Graphics ON switch
allows the graphic filters to be taken out of circuit for
comparison checks. The adjacent LED illuminates when the filters are IN circuit
(i.e. the graphic is functioning).
3.
Gain control
adjusts gain at the input stage; ranging from -
∞
to +6dB. The
centre detent allows the unit to quickly be set to unity gain (0dB).
4.
Peak LED.
This
illuminates when the audio signal is within 2dB of clipping
(+18dBu) at the output. When this light is on, there is a good chance that boost
applied in the equaliser’s filters will cause clipping. To combat this, reduce the
input gain or the source’s output level.
