Lexicon MX400 overview

  • 1Description

The MX400 from Lexicon is a stereo/surround multi-FX processor offering rich, luscious reverbs, delays and modulation effects in a hardware unit with the flexibility of DAW VST/AU plug-in integration and without bogging down your CPU or resorting to expensive processing cards. The quad processing unit is equipped with four 1/4" inputs and outputs, two digital RCA (S/PDIF) inputs and outputs, and a USB cable, which provides control of all automation and recall parameters as you would with a software plugging, but with the sonic benefits that only Lexicon hardware can offer.

Also included with the "hardware plug-ins" for Mac and PC (32-bit only) is a copy of MX-Edit Librarian software, which allows you to store and recall custom programs or pull up your choice of 223 genuine Lexicon settings including 25 dedicated Surround Programs. There are seventeen Lexicon reverbs, seven delays and eight modulation effects plus dbx compression and de-essing available. For non-computer operation, the unit provides a generous LCD display with large knobs for quick navigation and easy programming. The MX400 ships with a power cord, USB cable, and a MX Edit/USB driver CD.

    Lexicon MX400 reviews

    MX400 Dual Stereo/Surround Multi-FX Processor with DAW Integration (1/4" Connectors) is rated 4.7 out of 5 by 3.
    Rated 5 out of 5 by from Great bang for the buck Recently replaced my older Lexicon unit with the MX-400, and have not been disappointed. Dual stereo processing, dbx compression, de-esser, hardware plug-in technology...hard to complain. Thus far I have stuck mainly with the reverbs -- hall, plate, & room all are of the typical high-quality one has come to expect from Lexicon. Interface is also very nice: when manually tweaking FX on the unit itself, Lex has included enough buttons and knobs on the front to offer the user the ability to make changes in a fairly quick and intuitive way. Tweaking FX from a computer workstation couldn't be easier, and all changes are stored the same way as software based FX plug-ins (instant recall from within a sequence!). Highly recommended.

    Rated 5 out of 5 by from For those who want a Lexicon! This is a great reverb unit. In fact, 2 units for the price of one. Two independent processors. I mostly dont use the delays, choruses and compressor, but the reverbs are really pro! And the VST capability is a great thing, so you dont have to manually tweak the controls. Totally recommend!

    Rated 4 out of 5 by from No PCM96 but good for the price Don't be fooled by the name Lexicon on the front panel. This is no Lexicon PCM96S. However, at its current heavily discounted price, it doesn't need to be one either. The first algorithm I tried was Large Hall. People familiar with Lexicon higher end offerings will see it has some of the parameters of the Random Hall algorithm on their high-end units. It's possible to edit the hall size, and like the PCM90 and other high-end units, changing the size affects the reverb time. The maximum size for Large Hall is smaller than it is on the PCM90, 36 instead of 39.44 meters, and the maximum reverb time is shorter too: just under 20 seconds instead of over 60 seconds long. Other features from the Random Hall algorithm are here: It's possible to adjust the shape and spread of a swell that the sound begins with, diffusion can be adjusted (like it can on a lot of other mid-to-high end reverbs), and there is a simplified single tap early reflection (ER) delay, which, like in the PCM90 Random Hall, is a delay signal passed through the diffuser. Unlike the PCM90 random hall, there is not a second delay line with feedback, and both stereo channels are forced to share the same ER delay time on the MX400. More disappointing is that there are no spin and wander values that high end Lexicons have, and I really miss it, especially with a long 20 second reverb. While the MX400's large hall with a 20 second decay can sound good with a percussive sound with a lot of harmonics, a fairly mellow synth pad sound ended up, with a 20 second decay, having a really unpleasant reverb tail with a lot of frequencies ringing. I was able to get that mellow pad sound to sound good in the MX400's reverb, but I had to change the algorithm to chamber and have a reverb tail that was only a couple of seconds long; in this setup, the sound nicely thickened the mellow synth pad and any ringing in the reverb's tail was almost inaudible. There are low cost computer-based VST plugins which sound better than the reverb on this unit. On the other hand, the MX400 has some really nice non-reverb algorithms. Its chorus is subtle, but thickens up a sound. For something more obvious, its phaser is really nice on synth pads. The detune algorithm is also good for thickening up sounds. One really nice thing about the MX400 is that it has 1/4 connectors. Furthermore, it's possible to tell the MX400 to accept a mono signal on just the left channel, which it then routes to both stereo inputs before processing it. It allows me to add some basic signal processing and thicking to my synthesizers which do not have built in effects, even when recording two synths at the same time. So, while it's no PCM96S, or even a good VST computer reverb, it is the perfect unit for adding effects to keyboards without their own built in effects.
