4. CONTROL ELEMENTS
EQUALIZATION
Y ou have three EQ control for each mono and stereo input
channel each providing +/-15dB of boost and cut (-MID is
+/-12dB). The signal will be unaffected when the controls
are on center position. Y ou may use an external equalizer
to make up a mix properly but a master equalizer will not
have effect on a single channel and you may overload the
signal easily. Individual EQ will give you a much better
control on single tracks.
5 HI
If you turn this control up, you will boost all the
frequencies above 12kHz (shelving filter). Y ou will
add transparency to vocals and guitar , and also
make cymbals crispier . Turn the control down to
cut all frequencies above 12 kHz. In such way,
you can reduce sibilances of human voice or
reduce the hiss of a Tape player .
6 MID
This is a peaking filter and it will boost/cut frequencies with their center at 2.5kHz.
This control will affect especially upper male and lower female vocal ranges and also
the harmonics of most musical instruments.
7 LOW
If you turn this control up, you will boost all frequencies below 80Hz. Y ou will give
more punch to bass drums and bass guitar; and you will make the male vocalist
more "macho". Turn it down and you will cut all the frequencies below 80Hz. In this
Way, you can avoid low-frequency vibrations and resonance thus preserving the life
of your woofers.
8 AUX
This control is used to adjust the level of respective channel signal sent to the
Auxiliary Bus. The configuration is post-fader so the signal sent to the AUX Bus
will be affected by the LEVEL control of that particular channel. In this typical
compact unit, the channel signal is not only assigned to external effect or
processor equipment directly but also to internal digital multi-effect.
NOTE: There is the possibility to configure this AUX control as Pre-fader as we
will explain later in this manual.
