4. CONTROL ELEMENTS
EQUALIZATION
The MIC channel is provided with 2 bands of equalization each one providing for up to
15dB of boost and cut. There will be no signal change with the EQ control in centre
position (0).
5 HI EQ
This is a shelving filter operating on frequencies
above 12kHz. It means that all the frequencies
above this level will be boosted or cut depending
on the rotation of this control. If you want to
reduce the sibilance of human voice or reduce
Tape noise, turn the knob down. Y ou can make
cymbals crispier or add transparency to
vocals and guitar if you turn the knob up.
6 LOW EQ
This is also a shelving filter operating on frequencies
below 80Hz.Turn the control down to reduce
unwanted hum or low frequencies resonance. Turn it
up to add more punch to your bass drums and give
more body to a Bass Guitar .
7 PAN/BAL
It stands for Panoramic/Balance. For the
MIC channel and with the control on (0)
position the signal is sent equally to the
Left and to the Right side of the main
mix. T urn the Control all to the left and
the Signal will be sent only to the left
side of the Main Mix and vice versa. In
case of the stereo channels the BAL
control is pretty much like a balance
control in your home stereo. T urn the
control left and the right channel will be
attenuated and vice versa.
8 LEVEL
This is the master level control for the relative
channel. If the MIC TRIM is set correctly,
as well as the output level of the instruments
plugged into the line-level channels, the
LEVEL control will be positioned in between (0) and 3 o' c lock. If you have to
turn the LEVEL control further up, it means that the TRIM ( and the instruments
output level ) is set too low and vice versa.
