STUDIO

The compact-but-luxurious Lexicon® 4x4 for studio or live terrain.

Plug-in programming & recall with
the power of Lexicon hardware.

You want the rich, luscious sound that’s defined studio reverb for
three decades: a genuine Lexicon hardware processor. But you also
want the flexibility of programming high-quality effects right inside
your DAW program…without bogging down your
CPU or resorting to expensive processing cards.

Have it all with the MX400. All parameters
of every reverb, delay and dynamic effect in this
powerhouse quad processor are available inside any
VST® or AU compatible DAW program. Just link
your computer to the MX400 with a USB cable
and control all automation and recall parameters
exactly as you would with any software plug-in
— while enjoying the sonic benefits only Lexicon
hardware can provide.

Along with our unique “hardware plug-ins”
for PC and Mac®, we’ve also included MX-Edit™
Librarian software so you can store and recall
custom programs or pull up your choice of 223
genuine Lexicon settings including 25 dedicated
Surround Programs.

At its heart, the MX400 is everything you would
expect from the company that invented digital
reverberation. Seventeen Lexicon reverbs, delays
and modulation effects plus dbx® compression and
de-essing. A generous LCD display and big comfy
knobs you can get
your hands around.

your Lexicon dealer.
And then get on the
road to creating a hit.

Meet the most Lexicon power ever offered in a super-affordable

1RU effects processor. Perfect for band PAs, churches and clubs.

We know you need to be able to make changes quickly, so we

designed the MX400’s intuitive front panel to
be a bare minimum of knob tweaks away from
any adjustment or effects change. For example,
three individual, assignable parameter controls
mean you don’t have to page through menus to
fine tune a reverb tail.

Because you can use its built-in dbx® com­pression and de-essing in tandem with reverb,
the MX400 is the perfect tool for taming
problem vocalists.

Finally, you can rely on the MX400 for years
to come, through countless load-ins and load­outs — although its sound is A-studio-quality,
we designed the MX400 to withstand dust,
moisture, shock, power surges and all the other
rigors of live sound use.

The first time you ever heard reverb on

an album track, chances are you were hearing
Lexicon. We invented digital processing.
And we’ve been perfecting it for thirty years.
