Stereo Effects Processor
The Mackie Running-Man 32-bit internal effects pro-
cessor is a mono-in, stereo-out effects processor, with
16 presets. It is fed by adjusting the aux FX control [27]
on each channel. The FX master knob [52] adjusts the
overall level entering the FX processor, and the OL LED
[53] shows if the level is too high.
The output from the processor can be added to the
main mix by adjusting the FX return fader [46]. Its
output can also be added to the monitor mix by adjust-
ing the FX to mon [54] knob.
49. PRESET DISPLAY
This display shows the number of the currently
selected effects preset, as shown in the list of presets
silkscreened to the left of the display.
50. PRESET SELECTOR
Rotate this knob to increase or decrease the number
of the preset. It will fl ash in the display [49] until you
press this selector inwards to select the preset.
Scrolling back to the current preset or selecting a new
one will stop the fl ashing.
The available presets are shown in the table on the
next page, and are marked on the panel silkscreen.
(Only one preset can be selected at a time.)
51. INTERNAL FX MUTE and LED
When engaged, the internal effects processor is
muted. Its output will not appear in the main mix or
monitors, and the adjacent LED will come on. The
footswitch connection [16] becomes disabled, and you
will not be able to use the footswitch to mute or unmute
the effects.
If this switch is not engaged, then the internal effects
can be muted or unmuted with your footswitch.
52. FX MASTER
Use this knob to control the level of the signals going
into the internal effects processor. Adjust it carefully,
with your inner magical eye on the adjacent OL LED
[53] to prevent overloading the effects processor.
Fully down is off, 12 o'clock is unity gain, and fully up
is 15 dB of gain.
It also affects the level going out of the FX send out-
put [14].
53. OL LED
This LED illuminates when the effects processor is
being overloaded with too strong a signal (OL). Turn
down the FX master [52] if it is.
The signals going into the processor are affected by
the channel aux FX controls [27], and the channel fad-
ers [31]. Check the LED if you alter these controls.
54. FX TO MON
This knob allows you to add the output of the internal
FX processor to the stage monitor mix. Fully down is off,
12 o'clock is unity gain, and fully up is 15 dB of gain.
