COURSE GAIN Pot:
This is the rotary potentiometer immediately below the MIC/LINE switch.
The scale around the pot is meant for an approximate guide and is in dB.
When turned fully clockwise the level of the channel is increased by 30dB.
When turned fully anticlockwise the gain of the channel is reduced by 10dB.
‘Nominal Settings’ The following are an approximate guide:
If a professional mini disc is connected then turn the pot to 0.
If a non professional cassette recorder is connected then turn the pot to +10.
If a microphone is connected then turn the pot to +20.
LF CUT SWITCH (Low Frequency):
This is the 3 position switch below the course gain pot. It affects how much
low frequency audio is allowed to pass through the mixer. In the centre
FLAT position it does not affect the low frequencies. In the left 80 position
any audio below 80Hz is reduced by passing through a 12dB per octave
filter. In the right 160 position any audio below 160Hz is reduced by passing
through a 12dB per octave filter.
FADER:
This is the channels audio level adjustment that affects how much audio from
that particular channel ends up in ‘mix’ (output) and can also be used for
‘fine’ gain of the audio level. The printed scale to the right of the fader is in
dB, is approximate and meant as a guide. In it’s closed position (furthest
away from the LF switch) no audio will pass through the channel to the mix
output. The further open the fader is (the closer to the LF cut switch) the
more audio that will go to the mix output. The average position to set the
fader is marked on the scale as 0, when used in this postion an extra 10dB of
gain is available by opening the fader fully and if needed the level can be
reduced by slightly closing the fader.
PPM OUTPUT LEVEL METER
This is the 14 LED column on the top panel. It provides a visual indication of the level of audio
at the outputs of the mixer. It has a Peak Program Meter (PPM) characteristic. Each LED covers
a 2dB range. Zero dB (the normal line up level) is marked on the scale to the left of the LEDs at
4 (or the first of the yellow LEDs). The normal program level that should go to the output is
+8dB (or the first red LED).
