JimboSpins's review"You can use it in a studio too"

Lexicon MX400
The Lexicon MX400 is a dual stereo style reverb. It is a rackable unit that will only take one rack space and it has an LCD screen so you can create the reverb you want to work with. It is easy to set up but could take a little time figuring out the navigation and sub menus. The special thing about this unit is that you will have full control over your reverb; all of the parameters can easily be edited and changed at the turn of a single knob.


There are 17 different reverbs total and a handful of delay and modulation effects. Right out of the box you will be able to do some cool stuff just by messing around with the reverbs and seeing how they sound. This unit is very fun to work with and it can be used in a professional manor too for your live set. You will be able to get the exact style of reverb and sound you want with minimal effort.


The MX400 is MIDI capable with MIDI in and MIDI thru. There are also XLR and TRS ins and outs on the back of the rack. The sounds you will get with vocals using this unit are truly amazing and you will love all of the variations of reverbs that you can create. For many of our live shows we have to have reverb and some of the speakers and processors that we work with do have reverb built into them but it is nothing like using the MX400 because you will not have full control nor will you have a lot of options to work with.


This is the best unit for the price, which you can work with to get the reverb you are looking for. You can use it in a studio recording too and add some solid reverb to your vocals and almost anything you want to add reverb too. This unit is very versatile and well built.

Available effects: reverb, delay, compression ... in short, a multi effects.

Effects are editable on PC via USB connection.

Model 19 "rack unit. Two independent effects processors can be connected in parallel with two effects on each stereo pair, or series.

Digital technology (no lamp)

Connection jack or XLR models according to what I've seen on the web.

Audio interface, USB and PC for editing MIDI IN OUT.


The general configuration is simple.
Setting effect is made with three rotary knob.

For its size and price, this multi is rather pretty, should be satisfied with a limited quality, who personally that I was satisfied up to certain limits.
I could see the limits on voice recording mixed in very acoustic pieces. And finally I sold this multi because I find the quality of the reverb Dasample GlaceVerb better (in nuendo use VST).


Disappointed by the quality of the reverb that does not sound quite natural. We feel the digital side "fake" and sometimes, as happened for which deteriorates the sound.

Effects rather to use for most prod electro, prog rock ... a summary of everything that does not require sound very natural and acoustic.


Used for a few months puisrevendu to continue my quest for rack does not deteriorate the signal by adding a numeric result too!

I have not tried other model rack, just tested and VST Dasample GlaceVerb is my favorite!

The choice of rack depends on what you want to do, it can be perfect for those who want a compact rack and work sounds way more electro for the live example. A friend is typed with a good guitar and delusions low!

Lexicon MX400
characteristics are very easy to find on the internet, so I will not dwell on ...
t ^ I liked about the workability and quality of the camera ...


Then, from the standpoint of ergonomics, I find it rather nice shape. in 10 minutes I had gone around the device and understand how to operate it.
besides, I do not usually change much effect during the concert, and there, no worries. Even in the dark. machine inspires confidence, is clear, even very clear. you know what changes, there comes more quickly in two or three rounds of buttons. ditto for saving a preset. 2 buttons in my backup was saved and the sound engineer of the next group could make its balance quietly and change everything he wanted.

Briefly, the machine is clean, intuitive, and easy access.


there, I'm a little less packed. from lexicon, I was expecting a little better.
Obviously, it sounds good, but it sounds artificial, a little mail. for the delay, nothing to say. it works pretty well, but they are not breathtaking (compared to machines 10x the price of course ...).

So I will say frankly that has for its money, the effects are fine (I have not tested the compression), but it is not yet the best I've seen (if we ignore the factor € course).
basically, if I had a budget of +-500euro and that I would like to buy a reverb to the live, I would certainly this one.


* For how long have you been using it?
used to rent 2x

* Did you try many other models before getting this one?
it is not mine ... cons but I've tried a few others still ...

* Knowing what you know now, would you make the same choice? ...
if I had to buy one in the budget, it would be this one.

* What thing do you like most/least about it?
maneuverability, ergonomics, design

* What is your opinion about the value for the price?
good, even very good.

Lexicon MX400
- Full of reverb, multiple delay, phaser, pitch shifter, chorus ...........

- Editable via a small program (plugged in usb to pc) allows you to configure the faster multi-effects: you set the mouse, the values ​​change in real time on the machine, the software is a remote control is very practice, it allows its settings to appoint more quickly is more clear.

This rack-2 processors, each processor can handle either 1 or 2 effects. We can therefore with two processes have 2, 3 or 4 effects. Each process' has a dual input mono (or stereo), if we choose 2 effects per proc, one can either choose to chain the two effects (AC comes in, then the other) or to split the (IN L in effect, IN R in the other end. STEREO OUT effects common to both) When you use two effects per proc ', we have LOTS less settings available, but the main settings.

I personally use sound systems in the MX400 often split analog (4 mono 4For effects, two stereo returns - one for each proc'-) and for my home studio in digital stereo (a stereo reverb sound via SPDIF in and out ) and AC Roulle!
REMEMBER TO SET UP WELL IN 'ROUTING' THE MX400 to match your config.

2in/2out-connector audio jack in proc sym symmetric, MIDI (never used), SPDIF (very convenient! And no loss in conversion N / AA / N for a config computer music AC syncs easily, y ' diode has a witness, in short you can not fool her)
the PSU is integrated (Schuko)


easy operation. be careful though each process is independent, that is to say that we need in a backup (or load) save the two processes one by one.
Otherwise I personally had problems with my screen.
But I bought OCCAZ .......... ah the OCCAZ ........'"&"} ¤ é # @!


I think it works very well.
the reverb slightly shiny but not "hard", they are fine but bright, airy. It's really good, "small hall" on a group of batteries and you take a good slap! I find it really clean, there's the flat, hall, bedroom ... Brief lot more or less normal. (Reverse reverb too! For fx)

live it doing very well! I think it breaks-old standards-spx, m-one company (so it explodes on the M300-M350 and other multi-effects to 150 € / 200 €)

in a home studio, connected in spdif it surpasses software reverbs (reverence, GlaceVerb ...) and being able to configure it in real time via real knobs (encoders finally!) gives the changes a lot! the work of the reverb is very interesting in general.


used for about a year ...
it's expensive (even for OCCAZ at 280 € it's expensive! do not forget!) but it works.
A problem with the screen does not convince me to dwell on the quality, but the processors work well, the machine is clean, solid, logical, Lexicon is the pioneer brand of digital reverb, it's pro and the rest AC even in models such as this not as pro as the PCM (but much prettier!).

To conclude, I find this very convenient ring road: 4 effects in one unit, it works. Other effects are not negligible, the chorus works very well (on analog synth, acoustic guitar, etc. ...), the delays are clean. Different routing to adapt the multi-effects to a lot of different configs.

Had I not had this problem of screen (very random) I certainly pushed the praise! I must admit that the AC slows me a bit.
But yes very good machine! advisable.
