Channel Operation
Setting levels (mic/line channels). Plug the cable into the appropriate input jack. If you
are using a microphone or an instrument with a low output level (such as an acoustic guitar),
pressing the +30dB switch will give you an extra measure of pre-amplification. After this is
set properly, control the volume of the input with the LEVEL knob.
Setting levels (dual-line channels). Plug the cable(s) into the appropriate input jack(s).
After this is done, control the volume of the input with the LEVEL knob.
Effect level. Dial in the desired amount of effects (reverb, chorus, etc.) using the EFFECT
knob. The effects are post-fader, which means that as the input level is increased, the
amount of signal being sent to the effects will also increase. If you want to increase the level
of the instrument, you may need to turn down the EFFECT knob.
If you want to use an external effect device, plug a cable into the Effect Send jack. (This will
disable the built-in digital effects of the GigaMix.) Then connect the outputs of the external
device to the Effect Return jacks on the GigaMix.
Monitor level. To control the amount of a given channel being sent to the Monitor
Output jack, use the MON knob.
Equalizer controls. There are three knobs in the EQ section for each channel: HI, MID,
and LO. These give you the ability to shape the sound of each channel individually before it
is sent to the outputs.
Operating the Effects Section
Selecting the effects program. The GigaMix has 100 different effect programs from which
to choose. They are arranged into categories for ease of location. To select a new program,
turn the knob next to the PROGRAM display. When you reach the desired number, push
the knob to call up the new program.
Bypassing the effects. To hear what the mix sounds like without effects, press the
BYPASS button. The yellow LED will light to indicate that the effects are bypassed. To
bring the effects back in, press the button again.
Note: You may also use a footswitch to bypass the effects. To do so, plug a footswitch into
the EFFECT BYPASS/FOOTSWITCH jack at the bottom middle area of the front
panel.
Effects Clip/Signal LEDs. If you are using the built-in effects, make sure the combined
effect settings of each channel are lighting the green LED (Signal) but not lighting the red
LED (Clip). If the signal into the effects is clipping, reduce the setting of the EFFECT
knobs for one or more channels.
