GIGAMIX 4CD OWNER’S MANUAL
Before making any power connections, make sure the GigaMix’s power switch is turned off.
• Plug the female end of the power cable into the GigaMix’s power socket.
• Plug the male (plug) end into a properly grounded power outlet.
Making Audio Connections
Start by making sure the GigaMix’s power switch is turned off. Then use either 1/4” or XLR
cables to connect your instruments and microphones to the GigaMix. After this, you may
connect speakers to the GigaMix. There are several ways to do this:
• Main (house) speakers. Connect two cables from the GigaMix’s two rear outputs to a
matched set of speakers. For optimal power output, the total rated load of the speakers
attached to these outputs should be 4 ohms.
Note: You may daisy-chain several speakers, if necessary, as long as the total rated load of
the speakers attached to this output is no lower than 4 ohms.
Note: the front panel Main Output jack is not powered. It may be used to run the Main
mix into another mixer for recording purposes.
• Unpowered monitors. If you want to use an external amplifier to power your monitors,
connect a cable from the GigaMix’s front-panel Monitor Output jack to a high-quality
amplifier. Then connect the output of that amplifier to one or more monitor speakers
according to the instructions in the amplifier’s manual.
Connecting a Tape Player
To connect a tape player or other device, plug the left and right audio outputs of your source
device into the 2-Track Return jacks. Control the level of the music with the 2-
TRACK/CD LEVEL knob in the Main section.
Note: Plugging cables into the 2-Track Return jacks will disable the built-in CD Player.
To capture the performance on a recording device, connect two cables from the 2-Track
Send jacks to the audio inputs of the destination device. Adjust the recording level using the
destination device’s input controls.
Connecting External Effects
To use an external effects device such as a reverb or chorus, connect an audio cable from
the Effects Send jack of the GigaMix to the input of the external effects device. Then run
an audio cable from the output of the effects device to one of the Effect Return input jacks
on the GigaMix. If your external effects device has stereo outputs, use two cables to connect
the left and right outputs of that device to the Effect Return jacks on the GigaMix.
The level sent to the external device is controlled by each channel’s EFFECT knob. The
amount of external effect coming back to the GigaMix is controlled by a combination of the
controls on the external effects device and the EFFECT RETURN controls for the Main
and Monitor sections of the GigaMix.
Note: Plugging a cable into the Effect Send jack will disable the built-in digital effects of the
GigaMix.

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.

The Main Section
Controlling the master volume. The MAIN MIX knob is used to boost or reduce the
overall level being sent to the Main outputs of the GigaMix.
The graphic equalizer. In addition to the three bands of EQ possessed by each channel,
the Main section of the GigaMix has a 9-band graphic equalizer. This affects the overall
sound of the mix before it is sent to the Main outputs.
Controlling the master effects level. Use the EFFECT RETURN knob to adjust the
level of the effects for the entire mix.
Adjusting the CD/Tape volume. To raise or lower the volume of the incoming pre-
recorded music, use the 2-TRACK/CD LEVEL knob.
Phantom power. If you are using microphones that require phantom power, press the
PHANTOM POWER button. This will not affect microphones that do not use phantom
power.
Rumble filter. If you are experiencing excess microphone-handling noise or other low-
frequency noises bleeding into your microphones through the mic stands, for example, press
the RUMBLE FILTER button. It will reduce all frequencies below 75 Hz (which also can
help to reduce ground hum).
The Monitor Section
Controlling the monitor volume. The MONITOR MIX knob is used to boost or reduce
the overall level being sent to the monitors.
Controlling the monitor effects level. Use the EFFECT RETURN knob to adjust the
level of the effects for the entire monitor mix.
Adjusting the CD/Tape volume. To raise or lower the volume of the incoming pre-
recorded music, use the 2-TRACK/CD LEVEL knob.
