Alesis 6FX, 8FX owner manual Channel Operation, Operating the Effects Section

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.

Pan position (GigaMix 8FX only). Set the stereo placement of the input device using the PAN 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. If the Power Amp Mode button is set to MAIN-MON(up), this signal will be sent to the Speaker Output 2 jack on the rear panel as well.

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.
