NOTE: Either the MIC or the LINE input of a given channel can be connected at one time. Never connect both
simultaneously to the same channel.
3. INSERT
These mono channels are equipped with insert jacks to connect external signal processors such as
compressors, noise suppressors or effect devices, to the individual input channels. Insert points are useful
for adding dynamic processing or equalization to a channel or the mix. Unlike reverberation, which is
usually added to the dry signal, dynamic processing is normally applied to the entire signal. These jacks
can also be used as a direct output by sending the signal from the ring. To do so, insert a ¼" plug halfway
into the jack so the tip of the plug connects to the ring of the jack.
4. TRIM
The TRIM control adjusts the input sensitivity (channel gain) of the MIC and LINE inputs on the mono input
channels. This control can be adjusted to accommodate input signals from a wide variety of sources, from
the high outputs from keyboards or drum machines to the small signal outputs of microphones. This wide
range eliminates the need for MIC / LINE switching. The best S/N balance and dynamic range will be
achieved if you adjust the TRIM control on each channel separately so that the PEAK LED (11) for that
channel lights occasionally.
NOTE: This control should always be turned fully anticlockwise whenever you connect or disconnect a signal
source to one of the inputs.
5. EQUALIZER
All mono input channels are fitted with three-band EQ. The upper (HIGH) and lower
(LOW) shelving controls have their frequencies fixed at 12kHz and 80Hz respectively.
The midrange control has a peaking response, with Q fixed at 2 octaves and the
frequency at 2.5kHz. All three bands have up to 15dB of cut and boost with a centre
detent for "off".
6. AUX SEND 1, 2
Both AUX SEND 1 and 2 are mono and post EQ, and control the level of the signals
sent to the AUX buses.
• AUX SEND 1 is pre-fader and the signal sent to the AUX 1 bus will be unaffected
by the channel fader setting.
• AUX SEND 2 is post-fader and the signal sent to the AUX 1 bus will be affected
by the channel fader setting.
For almost all effects send purposes you may want to use the post-fader AUX 2 so that when a fader level
is adjusted, any reverb sent from that channel follows the fader. Otherwise, when the fader is pulled down,
the reverb of that channel would still be audible. You can also use the AUX SEND 2 to feed inputs to a
multi-track recorder or any unbalanced line level application. On the other hand, for cueing purposes and
monitor amplifiers, use the pre-fader AUX 1.
8. FX Control
This control alters the signal level sent to the FX send outputs and the built-in digital
effects processor. The FX send signal can be used in conjunction with external signal
processors (this signal of which can be returned to the mixer via the AUX return
input), or simply as an additional auxiliary output.
9. MON Control
The MON control is designed for feeding a separate monitor mix to the musicians
onstage via the MON output jack.
10. PAN Control
The channel PAN positions the output of the channel in the stereo field of the main mix if the L-R selection
switch (13) is depressed). Its constant power design ensures there are no level discrepancies whether the
signal is hard-panned, centre-staged or somewhere in between. The channel PAN also determines the
stereo position of any signal routed to the G1-2 bus when the G1-2 bus is selected with the G1-2 switch
(14).
