## Description

desertcart.com: Lexicon MX400XL 4-in/4-out Reverb/Effects Processor with USB "Hardware Plug-In" Capability and XLR : Everything Else

Review: The sheer flexibility of the MX400 is pretty astounding at this price point - Ok, so you're looking for a reverb/effects unit but don't necessarily want to step up to the $1000 price range for a spx2000 or similar units... Well, look no further. The sheer flexibility of the MX400 is pretty astounding at this price point. You are essentially getting 2 stereo processors with a great range of reverb, delay, phaser, detune, de-esser, etc. options at your fingertips. It really is a very intuitive menu setup if you have worked with other outboard gear before, with a fairly mild learning curve if you haven't. Parameter editing is right there for you with the A/B/C knobs affecting the most common parameters of a particular effect, and further detailed editing is 2 clicks of the page/select button away. The in/out setup and mix routing offers a way to really blend all kinds of different effects together, do 4 channel surround, or even run 4 mono effects. Now I haven't delved into the usb portion of the unit itself as I run Protools, and would prefer to set it up as an "analog" in/out for my purposes, but if you're running a VST compatible DAW then it might be something that helps sell you on ease of use for the unit. It does only accept 16 or 24 bit 44.1k or 48k digital signals, so if you normally "oversample" to a 96k or some such this might be cause to run it as analog in/out only. As most home studio users do 24-bit 44.1k or 48k in their sessions nowadays anyway, it's not that big of an issue. With all that being said, this unit is GREAT for adding space or mild effects, but not something to create wild affectation of the original audio. Factory programs are decent but not pro studio amazing, however user programs are very easily stored and brought back with just a few button presses. I do wish it had a few more LED's for input monitoring, but at this price not something to complain too much about. Overall, best unit for sub $1000 money (blows out TC Electronic units for sound quality) and fits a ton of uses in your rig! I highly recommend checking out the manual at http://www.lexiconpro.com/en-US/products/mx400/downloads_and_docs for a real look into the huge amount of options this unit will give you!

## Questions & Answers

**Q: What's the range of the input gain? i'm wondering if it can boost a -10 dbv guitar amp effects loop send up to +4 dbu or thereabouts.**
A: No, the nominal levels for both input and output are +4 dBu, so you will not have any appreciable gain.

**Q: How’s the pitch shifter I’m a singer looking for a harmony pedal that I don’t have to set the key to every song or have it plugged into an instrument**
A: Try a Boss VE-8

**Q: these effact machine better than effect build in allen & heat zed10fx ? i'm looking for good effect for my home karaoke . any suggestion . thanks**
A: While the effects in your Allen & Heath are pretty good.  The Lexicon is a step up.  Plus add the feature of designing your effects and save them for instant recall.  It comes in handy.  Remember this is a duel engine unit.  This allows you the ability to have independent control over two separate effects at one time.  It is worth the money.  I have used Lexicon effects for decades in high end recording studios.  There is a pretty impressive pedigree behind the name...

**Q: how long is the usb cable? does it come with one?**
A: It does not come with a USB cable.

### ⭐⭐⭐⭐⭐ Lexicon. Just that one word says it all. Lexicon. The best in the business.
*by H***N on April 15, 2018*

Lexicon. Just that one word says it all. Lexicon. The best in the business. As a professional musician and sound engineer for over thirty years, I have never heard a reverb better than or equal to Lexicon. Often, when a company invents something (in this case digital reverb), another company comes along at some point and either improves or equals the product. This can not be said for Lexicon. There is a specific depth and clarity to Lexicon reverbs, and I'm pleased to say they can be found within this incredible unit. The chorus effects are outstanding also. I could go on and on with praise. I've worked with a couple of the PCM units in the past so I'm very familiar with the Lexicon sound. In short, if you want the most incredible lush reverb on this planet, get a Lexicon. You will absolutely not be disappointed with the MX400.
