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. ‘On’ switch allows the graphic filters to be taken out of circuit for comparison
checks. The adjacent LED's illuminate 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. Thisilluminates 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.
5. High-pass filter bypass switch allows the filter to be taken out of circuit. This
allows you to hear its effects when compared to the unfiltered sound, and also
to allow low frequencies to pass unaffected.
