Stereo Effects Processors,
Headphones, Talkback, Main
and Groups Mix*
There are two identical Mackie Running-Man 32-bit
internal effects processors. They are mono-in, stereo-out
effects processors, with 24 presets each. Signals to these
effects processors come from adjusting the FX1 and/or
FX2 aux send [29] on each channel and the FX masters
[61].
The stereo output from each processor may be added
to the main mix using the 'FX to main' knob [62]. The
stereo output from each processor may also be added to
aux 1 and/or aux 2 by adjusting the 'FX to aux' control
[62].
* Affectionately referred to as the 'meat 'n potatoes'.

Or the FX returns may be routed to the stereo input
channels[23/24 on the 2404 VLZ3, 31/32 on the 3204
VLZ3], using the the FX1 and/or FX2 switches [44].
This allows for way more flexibility. For example, you
can EQ the FX and send them to any aux, group, or
main. Just remember to turn the 'to aux 1', 'to aux 2'
and 'to main' knobs [62] fully counter-clockwise to
avoid double-bussing.
The talkback feature allows the engineer to
communicate with the talent either through the phones
output [17] or the aux 1-4 send outputs [13] using
an external talkback microphone. This saves a lot of
shouting over the audience's heads as you set up the
talented one's stage monitors to their peculiarly-picky
satisfaction.
61. FX1 and FX2 SEND MASTER
These knobs control the level of the signals going into
each internal effects processor. Adjust them carefully,
keeping an eye on the adjacent sig/ol LED [63] to
prevent overloading the effects processor.
62. FX1 and FX2 TO AUX 1/AUX 2/MAIN
These knobs route the effects output to aux 1, aux
2 and mains independently. Use aux 1 and aux 2 to
provide effects to monitors. Slowly add effects to the
monitors by turning the 'to aux 1' and 'to aux 2' knobs
clockwise. Use the aux master to monitor the amount
sent. The FX output to the mains will be heard directly
from the PA.
63. SIG/OL LED
These dual-LEDs illuminate green when the signal
level going into each effects processor is within a good
operating range (sig). They illuminate red if the effects
processor is overloaded with too strong of a signal (ol).
Turn down the send master levels [61] and check the
channel sends if these light red regularly.
The signals going into the processors are affected by
the channels' aux 5/6 sends [29], the channel gain [23],
EQ [31-36], and channel faders [43], as well as the FX
Send Master [61].
64. PRESET DISPLAY
These displays show the number of the currently
selected effects preset, as shown in the list of presets
silkscreened above. Rotate the preset selector knob
right or left to change a preset.
A new preset will be loaded approximately 1/4 of a
second after you stop turning the knob, and it will be
stored into the FX memory after about one second.
When the VLZ3 4•Bus mixer is turned on, the FX
section will load up the last-used preset.
