The ease of plug-in control merges with Lexicon hardware processing power.

The Lexicon MX400 is a single-rackspace, 4-in/4-out unit combining an intuitive front-panel design with Lexicon's "Hardware Plug-In" technology, a unique USB connection, and a VST/AudioUnits interface for use with software recording platforms.

Studio pros will be glad to know that the units also feature a wide array of the rich, complex reverb algorithms, delays, effects and dbx dynamic effects that have made Lexicon a favorite for recording.

The USB Hardware Plug-In format gives you complete plug-in control over your MX400 within any VST or AudioUnits software environment, enabling you to control all automation and recall parameters exactly as you would with a software plug-in while enjoying the sonic benefits Lexicon firmware provides.

Equally at home for live applications, the MX400 supplies the FOH/live sound engineer intuitive front panel control with a backlit LCD screen for parameter displays. 4 in, 4 out 1/4" TRS balanced I/O. Also offers 4-channel surround algorithms.

    this unit is unbelievable. where do i start? i know that lexicon are know for their reverbs, which are, of course fantastic, but the chorus, in my opinion, is by far far the best i have ever heard, period. i'm not big on presets, on any unit, for that matter, so i really don't bother with them because the effects are adjustable in just about every way, which really is the point, isn't it? i just can't get over how sweet the chorus sounds. i also have the mx200, which is use for delay and the "desser" and that combined with the mx400 is just about perfect. and the icing on the cake? $300??? it's a steal as far as i'm concerned. if you are looking for a multi effects processor with everything you need, look no further, you WILL be happy. thanks lexicon

  • AWESOME!!!

    As reviewed by James Kreamier on 1/2/2010

    Alright, first off, the disc that came with this unit to use it as a VST plug for Cuebase was not compatable with Vista. This proved to be no problem as the download for Vista is on the lexicon web site. Secondly, Cuebase or other recording software will try to assign the mx400 as a midi device, and you will need to disable this function in your recording software for it to open the mx400 as a VST plug in. This was also a minor issue. If used as a VST plug in, the sound must be ran through the S/PDIF Digital Input/Output to your computer as the USB connection is not set up to run sound. Third, the mx400 has the best vocal effects I have ever heard. The presets are absolutly awesome and I dont forsee that I will ever have to make a custom setting. To utalize the full surround sound of this unit you will need a mixing board with aux 1 and 2 sends and 4 returns or a usb adapter that has at least 6 plug ins. Don't let any of this scare you, as this unit is awesome and well worth the few tiny issues I have ran into. If you are interested in taking your recordings to the next level or you just need an awesome live sound, the mx400 is the BOMB!

    As reviewed by Aurelius the Ace of Cats on 5/11/2010

    I had a few other effects units in my studio racks, not to mention the occasional stone-age sampler or whatnot i still use for certain dirty effects... my main verb unit was an T.C. M one xl. nice unit, used still for large verbs(drums& whatnot)... I like a variety of effect colours...Deal is, nobody knew much about this one, so after about 3 months of dancing around it i just ordered one... Seriously, if you've been skeptical about the price vs. features, its not too good to be true. The effects are clean, not opverly sterile, easy like butter to edit and save, gain stageable, and none of that b.s. digital noise i've encountered with other units. tons of wonderful reverse effects, not to mention tons of routing options. plug-ins are for cats who can't afford rack gear, or sissies who are too afraid to commit to coloured tracks, so needless to say, i'll probably never use it "in" the daw, but this may work well for someone else who needs that. as far as a harwired piece its got the gravy all over it! get one, you seriously can't beat it for the price.
