Channel controls
6.
GAIN
This control adjusts the input level to match lower output sources to
suit the channel line level. Increase for lower output sources
(e.g.) microphones or reduce for higher output sources (line level)
If the PEAK LED (below) is lighting constantly, the GAIN set too high.
The METER select button enables visual monitoring of the MAIN OUT
or PHONES out, which is useful to check if overall levels are too high.
7.
HIGH EQ
This control can boost or cut the
high frequencies by ±15dB
(12 o’clock
position is zero)
8.
LO EQ
This control can boost or cut the
low frequencies by ±15dB
(12 o’clock
position is zero)
9.
PAN/BAL
“
PAN
”
is short for Panoramic, meaning the position that the signal appears in the
stereo field. Moving the control clockwise fades the signal over to the right-hand
output and moving the control anticlockwise fades the signal over to the left-hand
output.
“
BAL
”
is short for Balance and applies only to the stereo channel L+R ratio.
10.
VOL
“
VOL
”
is short for Volume. Turning this control clockwise increases the level of the
channel signal sent to the output section.
11.
Peak LED
The peak LED will light when the channel is overloaded. Take care to only allow this
to happen very briefly on the loudest parts of the audio or not at all. If this LED lights
continually for any length of time, reduce the GAIN, channel volume or EQ until it
only lights momentarily.
