Ideal for musicians, podcasters, and home studios, it features premium op-amps for crystal-clear sound, a space-saving footprint, and comes ready to use with a 12V power adapter included. ## Description From the manufacturer MX400 Ultra Low-Noise 4-Channel Line Mixer Ultra-compact 4-channel line mixer Highest sonic quality even at maximum output level Input Level control for each channel Power adapter included MICROMIX MX400 Despite its ultra-compact size, the MICROMIX MX400 4-channel line mixer is really big on features! Providing the highest sonic quality at all output levels vs. the competition, the MX400 features ultra low-noise 4580 operational amplifiers for outstanding audio performance – the same chips as the ones found in its much bigger brethren. Connections Expanding on the capabilities of standard-size mixers is where the MX400 works its magic, for instance when it is used as a sub-mixer. If you are running short on available channels on your “big” mixer and need to add 3 more keyboards to your mix, just connect them to the MX400, dial-in the mix – and connect MX400’s output to a single input on your main mixer. This is just one example of how the MX400 can add versatility to your current setup – just imagine the possibilities! Small and Superb The MX400 is the ideal solution for mixing multiple line-level signals on a budget. Sure, it’s as cute as a button – but you’ll want to own one because of what it brings to your performance. And the MX400 is so very affordable. Check one out at your Behringer dealer, or place an online order today! Review: Nice little mixer - Needed this because my guitar amp only had one input. Ended up plugging in a few guitars a mic and my looper. Easy to set up and balance, do get a very slight hum but not so you would notice and no impact on the sound. I think it is more the fault of my aging amplifier than this mixer. Overall, small, neat and very capable for people like me that don’t have too much to spend. A great asset to my setup that has given me good flexibility with both guitars and mic for a low price. Review: Excellent piece of kit, but please look at what it is you're buying! - This is very impressive indeed, especially at the price, but quite a few people seem to be having problems simply because they don't know quite what they're buying, so here's a quick introduction to mixer technology...... Firstly of course, it's clearly sold as a "4 Channel Mono Line Mixer", so I really don't understand why so many are complaining that it isn't stereo :~) A line mixer is a specific thing, it's function is to provide a sub-mix of line level signals, in this case mono signals, and to output a single line level signal. The output has to go to a device that will take a line level signal (amplifier, main mixer, some effects pedals, etc....) It won't directly drive a speaker. You might get a quiet or distorted sound out of a pair of headphones, but extended use will probably damage the unit as, because of the impedance mismatch, the circuitry will be drawing far too much current All audio equipment, no matter how good or expensive, generates some background noise, this is known as the noise floor. Although they don't give any figures, I've measured it and the noise floor is ridiculously low, and running at the levels it's designed for any noise is, for practical purposes, non-existent. Although not designed for it, the unit is versatile enough to work with much lower level signals from guitars and even some microphones, but in that case you have to be careful with levels otherwise some background noise can become audible. Any background noises you get other than a hiss are down to dodgy output stages on whatever you've got plugged in (Phones, tablets and cheap laptops are notoriously bad!). At the other end, if the signals going in are too high it will eventually distort. If so , you just have to turn everything down! I originally got mine for general studio duties - temporary hook-ups of odd bits of equipment, but within an hour it found a permanent home attached to a Behringer RD-8 which has separate outputs for each drum sound. I can now route some of them out for effects processing, recombine them, and either back into the return socket on the RD-8 or to a second main mixer channel. Looks like I'll have to buy another one...... ;~) ## Features - MONO MIXING MASTERY: The MX400 is designed for mono signal summing, perfectly blending up to four audio sources like microphones, synths, or drum machines into a single, powerful output. Ideal for streamlining your setup before recording or amplifying. - ULTRA-LOW NOISE PERFORMANCE: Experience crystal-clear audio blending thanks to premium 4580 op-amps. This mixer maintains the highest sonic integrity, ensuring your mixed signal remains pristine and noise-free, even at maximum output levels. - SIMPLE & PRECISE CONTROL: Each of the four channels features its own dedicated level control knob, allowing you to perfectly balance the volume of each input source for a professional and cohesive final mix. - COMPACT & VERSATILE SOLUTION: Its incredibly small footprint saves crucial space on your desktop or pedalboard. The perfect tool for home studios, live keyboard rigs, podcasting setups, and blending multiple guitar effects loops. - READY TO USE: A reliable 12V DC power adapter is included in the box for immediate operation. Please note: The included power plug may be a EU standard type; a UK plug adapter will be required for use in British sockets. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B000KGYAYQ | | Audio Input | Auxiliary | | Best Sellers Rank | 5,949 in Musical Instruments & DJ ( See Top 100 in Musical Instruments & DJ ) 2 in Unpowered Audio Mixers | | Brand | Behringer | | Brand Name | Behringer | | Connectivity Technology | 1/4" TS Connectors | | Connectivity technology | 1/4" TS Connectors | | Country of Origin | China | | Customer Reviews | 4.2 out of 5 stars 2,554 Reviews | | Global Trade Identification Number | 04033653020633 | | Item Dimensions D x W x H | 103D x 46W x 103H millimetres | | Item Weight | 0.01 Ounces | | Item weight | 0.01 Ounces | | Manufacturer | Behringer | | Manufacturer Part Number | MX400 | | Model Number | MX400 | | Noise Level | 16 Decibels | | Number of Channels | 4 | | Number of channels | 4 | | Output Connector Type | Jack 3.5 mm | | Power Source | DC Power Supply | | Power source | DC Power Supply | | Product Warranty | Community.

In THEORY - YES, but in practice, not advised. You'd need to feed pc1 left into input 1, pc1 right into input 2, pc2 left into input 3 and pc2 right into input 4. You'd then get 1 output (consisting of a mono output of left AND RIGHT channels from both pc's on a single socket - as I said, less than satisfactory. Far better use the Xenyx 502, which will support stereo outs! **Q: Does it work on 240 volts?** A: The power input is for 12 volts, but in the UK it comes with an adaptor so it can run off the mains supply (which is nominally 230 volts).The information on the adaptor states that it can handle voltages from 100 to 240 volts and draws 300 milliamps.Output is 12volts Direct Current - 150 mA. **Q: Would this work between a low impedance mic to an active speaker like most bands use now?** A: I use it for line level instruments into a guitar amp, which works fine. It has quarter inch inputs, not cannon, so any mics would need to use quarter inch cables. There is no gain or eq, so I would probably go for a mixer with more controls for a band. Saying that, it’s only £20, so if it doesn’t work as you want, you can always use it to chain four more inputs into a larger mixer. **Q: Since its mono, I'd only hear a signal through one speaker or do I hear same signal through both of my speakers? My speaker only has one 3.5 mm cable.** A: Depends on your cable. I assume your 3.5 mm cable is stereo, this will produce sound in 1 speaker. use a stereo>mono adapter to get same sound in both speakers. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice little mixer *by N***0 on 3 October 2021* Needed this because my guitar amp only had one input.

It is spec'd at 12V but works OK with 9V with the specially made power cable converter. It does come with an appropriate 12V power supply if you want to use a separate mains plug to power it. ## Frequently Bought Together - Behringer MICROMIX MX400 Ultra Low-Noise 4-Channel Line Mixer, Black - Behringer MICROAMP HA400 Ultra-Compact 4 Channel Stereo Headphone Amplifier - Cable Matters 5-Pack Headphone Adapter, Headphone Jack, 3.5mm to 6.35mm, 6.35mm to 3.5mm Adapter --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/48215608-mx400-micromix-4-channel-mono-line-mixer-for-guitar-synth](https://www.desertcart.co.za/products/48215608-mx400-micromix-4-channel-mono-line-mixer-for-guitar-synth) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-06-08*
