VLZ3 4•Bus
PREMIUM FX MIXER

2404 and 3204
VLZ3 4•Bus
The VLZ3 4•Bus takes the world-renowned Mackie 4•Bus
Series mixers to a whole new level, inluding the addition of
improved XDR2™ mic preamps, a redesigned mix bus, and
optimized active EQ on every channel. Additionally, USB
Recording and Playback, onboard dual RMFX+™ engines
and eight individual compressors come standard on every
VLZ3 4•Bus mixer.
The 2404-VLZ3 is equipped with 20 mono mic/line channels
while the 3204-VLZ3 comes standard with 28 mono mic/line
channels. Both mixers have two stereo channels with 4-band
equalization, four group outputs and inserts, and XLR and
TRS stereo and mono main outputs and inserts.
Each mono channel has an input Gain control with 60 dB of
gain, a sharp 18 dB/octave, 100 Hz Low Cut filter, a 3-band
EQ with sweepable mid, six Aux Sends, Pan, Mute, Solo,
assign switches, a 60mm fader and a Channel Insert jack for
connecting an external processor.
Other features include phantom power, mono and stereo
monitor outputs, a stereo tape input and output, a ¼-inch
stereo headphone jack, a dedicated talkback XLR jack,
stereo 12-segment LED meters, a BNC lamp socket, and six
Aux Sends and Inserts.
Aux Sends 1-2 are pre-fader. Aux Sends 3-4 have a switch on
each channel for selecting pre- or post-fader send, whereas
Aux Sends 5-6 are a fixed post-fader send, perfect for effects
loops. Auxes 1-6 have a master level control and all six
Auxes are post-EQ. There are four stereo returns with various
routing options for each return.
The VLZ3 4•Bus packs a unique 4x2 USB recording and
playback function, 2-Track Return selection, and features two
of Mackie’s patented Running Man FX processors (RMFX+™)
featuring 24 “gig-ready” effects, the returns of which may
be routed into the last two stereo channels for maximum
flexibility.
