Note: The channels have essentially
the same controls with some minor
variations between Channels 1-8, 9-16,
17-20, and 21-24. The five different
channel types are shown here.
1.
Mic Input: Connect a microphone
or line-level device to these inputs
with an XLR cable.
2. Line Input: Connect line-level
devices to these inputs with 1/4"
cables.
3. Insert: Use a standard 1/4" TRS
cable to connect an external
processor (such as a compressor,
limiter, external EQ unit, etc.) to
this jack. The signal will be taken
after the channel's gain control
and returned before the channel's
EQ controls. The tip of the TRS
connection is the send, and the
ring is the return.
4. Gain: Adjusts the channel audio
level (pre-fader and pre-EQ gain).
Adjust this so that the Signal LED
lights up.
5. Peak LED: The LED will flash if
the signal is clipping. If this
happens, decrease the setting of
the Gain knob.
6. Compressor: Adjusts the amount
of compression on the channel,
applied by the mixer's built-in
compressor. The LED next to the
knob will light up when the
compressor is on.
7. Low Cut Filter: When this button
is depressed, that channel's
audio will be sent through a 75 Hz
low-frequency filter with a slope
of 18 dB per octave. This is useful
for reducing low-frequency noise
when using microphones.
8. Hi EQ: Adjusts the high (treble) frequencies of the channel.
9. Mid EQ: Adjusts the mid-range frequencies of the channel.
10. Mid Freq: Adjusts the mid-range frequency band (100 Hz – 8 kHz) affected by the Mid
EQ knob.
11. Hi-Mid EQ: Adjusts the high-mid-range frequency (3 KHz) of the channel.
