2404VLZ4 and 3204VLZ4
In pursuit of the ultimate “do-it-all” Live Sound Mixer, we
threw in the kitchen sink and packed this bad boy with a full
set of processors allowing you to travel “rack free” while still
making professional sounding mixes.
For starters, we added not one, but TWO, of our patented
Running Man FX processors (RMFX+™) featuring 24 “gig-
ready” effects right into the board. This does not include
useless effects such as “the warbler” or the “insanity delay”,
but rather a suite of quickly accessible and useable reverbs,
choruses and delays that make coloring your mix a breeze.
Additionally, both FX processors feature a tap delay,
typically only available on an outboard rack. Delays may
easily be sync’d with the song at the tap of a finger. And
because we love flexible routing (hehe), the processed
signal may be sent direct to the mains and monitors from
the effects section or re-routed to the two stereo channels
to bring them through the EQ and aux section, utilizing the
60mm fader to draw them into the mix.
But wait, there’s more! The VLZ4 4•Bus has eight (yes,
eight!) single knob compressors to stop the dynamic signals
from poking out of the mix. Four compressors are located
on the last four mic inputs so that the most critical signals
(such as vocals, snare drum, the occasional jaw harp
or mountain goats) may be addressed. Plus, there are
single knob compressors on each of the four subgroups
so that grouped signals (such as a drum set or a choir
of didgeridoos) may be blended together for paramount
smoothness.
The VLZ4 4•Bus Series Mixers also feature a 4x2 USB
recording and playback function. This means that up to
four signals may be recorded simultaneously and a stereo
mix returned to the mixer for playback.
Bottom line? You have an awesome mixer with VLZ4 sound
quality, “built-like-a-tank” build quality and a recording and
processing feature set that is unparalleled. Congratulations...
and happy mixing!
APPLICATIONS:
Live sound mixing, houses of worship, clubs, gymnasiums,
banquet halls, conference rooms, boardrooms, multitrack
studio and field recording, video post-production,
multimedia applications, broadcast and many, many more.
