Thanks to MOTU's Hybrid interface technology, the Audio Express connects to any current Mac or PC via FireWire or high-speed USB 2.0. Connect your mic, guitar, keyboard, and digital input, and you are ready to make pro-quality recordings in your personal studio. It lets you quickly glance the levels of your mic, guitar, keyboard, and a S/PDIF device, right from the front panel. Each instrument has its own volume control. Route inputs directly to any output pair, each with its own unique mix: main outs, line outs, S/PDIF out, and phones.

Simplicity by design
Connect your powered speakers. Plug in your instruments. Adjust their volumes with the front panel knobs. Double-click to install the drivers. What could be easier? The Audio Express is designed to be simple to use, so you can focus on your music and performance.

Studio-grade sound
The Audio Express delivers MOTU's renowned, award-winning audio interface technology to your personal studio with the pristine audio quality, advanced engineering, and rock-solid performance that MOTU interfaces are known for worldwide.

You can use the Audio Express 8-bus digital mixer on stage for live performance, in your personal studio without a computer, or together with your host audio software as a low-latency monitor mixer. It gives you immediate, hands-on control of your mix using the front-panel knobs and status LEDs. To adjust the volume of an input, just turn its knob. The Audio Express lets you control mix volume independently from the input's trim level, so you never have to sacrifice sound quality for a balanced mix.

A separate mix for each output pair
The Audio Express mixer takes signals from its six inputs and mixes them to an output pair, such as the main outs. You control the volume of each input. Better yet, you can adjust input volumes differently for each output pair. In other words, each output pair can have its own unique mix. For example, you might create a balanced mix going to your PA via the main outs, but bring up the guitar for the mix going to your stage monitors via the line outs, so you can easily monitor your guitar sound. You get a separate mix for main outs, line outs, S/PDIF digital out, and phones.

As a live mixer
Because immediate volume adjustments are always within reach, the Audio Express serves as the perfect compact, portable live mixer, with or without a computer. Even without a computer, the Audio Express gives you complete control over all four mix busses with direct access to volume, mute and solo for each input.

As a studio mixer
Back in your personal studio, you can, of course, use the Audio Express to connect your mic, guitar, and other inputs to your computer. Sometimes, however, you just want to play your instruments without the computer. The Audio Express continues to serve as your studio mixer, even when your PC or Mac is turned off.

As a monitor mixer
When recording into your computer, host audio software can sometimes introduce a slight delay (latency) in what you hear as you track. You can use the Audio Express mixer, instead of monitoring through the software, to completely eliminate this delay.

On-screen mixing with CueMix app
CueMix FX gives you comprehensive graphic control over your mix and other settings in the Audio Express. CueMix FX can be operated side by side with any host audio software for Mac or Windows, and it can be controlled from the Mackie Control Universal Pro automated worksurface.

Hybrid Firewire/USB 2.0 connectivity
FireWire has long been recognized as a reliable, high-performance connectivity standard for professional audio interfaces. Meanwhile, high-speed USB 2.0 has also developed into a widely adopted standard for connecting audio devices to personal computers.

To fully support both formats, the Audio Express hybrid audio interface is equipped with a FireWire jack (400 Mb/sec) and a high-speed USB 2.0 jack (480 Mb/sec). This gives you maximum flexibility and compatibility when connecting to today's ever-expanding universe of Mac and Windows computers.

If your computer doesn't have FireWire, you can use USB. If it has both, then the choice is yours and may depend mostly on other peripherals you have.

Mic/guitar inputs
The Audio Express combo mic/guitar inputs are equipped with pristine, transparent preamps and offer individually adjustable 48V phantom power and -20dB pad. The 1/4" guitar jack provides high-impedance load characteristics suitable for passive and active pickups alike. For even more authentic feel and response when using virtual guitar amp and cabinet plug-ins, use a ZBox guitar impedance adapter.

Digitally controlled analog trim
The Audio Express's analog trim circuits deliver clean sound, combined with the precision of digital control. Trim is adjusted at the input, before the mixer, so it applies to all mixes. Mix levels are controlled separately from trim, so you never sacrifice sound quality for a balanced mix.

The Audio Express provides MIDI input and output featuring sample-accurate timing with supporting software. Connect a MIDI keyboard, sound module, or control surface, and you are ready to go. The FireWire or USB connection to the computer carries both MIDI and audio so you don't need to connect an additional USB cable for MIDI.

Connect any standard momentary footswitch to trigger hands-free punch-ins during recording, or map the footswitch to any keystrokes you wish in your host audio software.

SMPTE time code sync
You can resolve the Audio Express directly to SMPTE time code without a dedicated synchronizer via any analog input. The Audio Express provides a DSP-driven phase-lock engine with sophisticated filtering that provides fast lockup times and sub-frame accuracy. This technology represents the very latest in extremely high-performance, yet cost-effective digital audio clocking. DDS also allows the Audio Express to maintain an extremely stable clock while resolved to incoming clock sources that have substantially more jitter than the Audio Express itself.

SMPTE Console software
The included MOTU SMPTE Console software (for Mac OS X and Windows) provides a complete set of tools to generate SMPTE for striping, regenerating, or slaving other devices to the computer. Like CueMix FX, the synchronization features are cross-platform and compatible with all audio sequencer software that supports the ASIO2 sample-accurate sync protocol.

Add another Audio Express (or other MOTU audio interface) as your needs grow via a standard Firewire or USB 2.0 hub. The Audio Express provides driver-level support for resolving multiple interfaces with each other so that their audio streams never drift apart over time during recording or playback.

CueMix FX
The included CueMix FX software for Mac OS X and Windows gives you graphic, on-screen control of the Audio Express's on-board audio mixer, with up to four separate stereo mixes (a separate mix for output pair). For example, you can mix all the inputs to the main outs, but also mix them to the line outs with completely different levels than the main outs. Advanced features include a tuner, oscilloscope, FFT/spectrogram, and phase analysis tools.

The Audio Express includes AudioDesk, the workstation software for Mac OS X, which provides advanced recording, editing, mixing, processing, and mastering. AudioDesk delivers the power of modern digital audio workstation technology in an easy-to-use, inspiring multitrack recording experience. Together, AudioDesk and the Audio Express are a complete, professional recording studio for your computer desktop.

Outstanding Audio Interface for PC


from Fountain, CO

Comments about MOTU Audio Express 6 x 6 FireWire/USB 2.0 Audio Interface:

I have gone through many different audio interfaces and each of them have let me down for one reason or another... but this little sturdy box is something all together different. Different because there is no latency, different because there is no noise, different because it setup immediately without any hassels (running Pentium D 3.0MhZ, 2GB Ram, with Windows XP). It interfaces and is recognized by my Propellerhead RECORD and REASON, also by CUBASE. It is also different because it has an ON/OFF switch (right on front). It is different because you can use physical knobs to alter settings or use the software interface that easily resides with any of the DAWs I've used. My typical setup - inputs two keyboards and on sound module (via the TRS balanced inputs and SPDIF). Also, this is a solid little number with tough case and easily readable LEDs. I highly recommend this audio interface. Mike

Forget the Ap*gee, this is the best interface if you're on a mac!

By Joshua Pacada

from NYC

Comments about MOTU Audio Express 6 x 6 FireWire/USB 2.0 Audio Interface:

Just got my Mark of the Unicorn Audio Express. Had the AudioFire 4 (junk) returned it and it was between this, the Focusrite Saffire 24 DSP or the Presonus FireStudio mobile. Glad I went with the MOTU. Using an early-08 Perryn MBP, driver suite is intense and integrates so perfectly with mac, the keyboard volume controls work. Audio quality is clear and performance is stable (largely dependent on your system of course) and the unit is made in USA - it is of UPMOST quality - I'd travel with this piece! Overall very pleased with purchase, audiodesk DAW software a bit outdated though.

Good product


from Round Rock, TX

Comments about MOTU Audio Express 6 x 6 FireWire/USB 2.0 Audio Interface:

I had no trouble setting this up and getting it to work. Sound quality is very good. I'm new to digital audio interfaces and don't have anything to compare it to but I'm happy with the way it's performing. I have it on a PC right now but am planning on purchasing a Mac.

This thing bleeds quality. Low latency, great sound.

By aaron fabbri

from portland, oregon

Comments about MOTU Audio Express 6 x 6 FireWire/USB 2.0 Audio Interface:

I've used about four different audio interfaces over the last 5 years, and this thing is by far the best. I'm extremely happy so far. Likes: - Low latency on my mac. First time I've been able to software monitor (with effects!) and not notice much of a delay. (I use Ableton). This opens up brand new possibilities for live performance. This is why I'm so happy. (And there is always direct monitor if your machine is not keeping up). - Solid midi support. With the very low latency, again, opens up new live performance possibilities. - Driver. Along with the hardware, the quality of the OS driver is extremely important. The performance of the Mac driver is amazing. My macbook air 13" just flies with this thing. I can run the buffer settings very low without any drops or glitches. No hangs or crashes. - Solid build. Metal case. Made in USA. - Preamps. My recordings are sounding great under a variety of conditions. Decent headroom, super low noise, good sound. - Documentation. They invested in a decent manual. - Intuitive controls. Of course the half-rack form factor makes for cramped front panel, but they did a wonderful job fitting an intuitive interface into that small space. Once I learned it, I can remember it because it just makes sense. - Lots of channels for the price and quality. 4 in, 4 out, plus 2x2 digital. I can plug my old EMU USB 0404 into this thing via the SPDIF digital inputs, and add another two quality XLR preamps, and be recording 6 channels simultaneously. Drool. So I'm using my old audio interface, which no longer was supported and thus wouldn't work on newer OSs (win 7 and OS X lion), to get another 2 channels of great analog input. - Price. Really, for the quality of the drivers, the rugged hardware build, and the number of channels, it is a screaming deal. - Lots of independent mixes. Want a four channel headphone amp so everyone in the band can have their own mix? Included! Dislikes: - No major complaints so far. - The half rack form factor makes for a cramped control panel and rear inputs, but I quickly learned the controls.

Forget the rest. If you have a Mac this is the interface for you.

By David Rodriguez

from Orlando, FL

Comments about MOTU Audio Express 6 x 6 FireWire/USB 2.0 Audio Interface:

I've had my eye on this interface for months and finally decide to take my chances and buy it. It was a hard decision between this one and a Focusrite Scarlett 8i6 or NI Komplete Audio 6. And man, did I make the right decision. This has everything the other two lack so honestly it was worth every penny. First, it sounds great. I've tried it with Logic Pro 9 and Ableton Live 8 and set up was easy and quick. I will admit that the interface does take some getting used to since the knobs on the front share different functions, but it only took me about an hour to get used to it. It has plenty of routing options, can be used as a stand alone mixer without a computer, it's hybrid so I can use it with either USB 2.0 or firewire, it's compatible with both Mac & PC, it's portable, and as trite as it sounds it's built like a tank. If I ever got a flat tire I'm sure I could use it as a jack stand without any worries. The Focusrites and Native Instruments interfaces (although good) lacked certain features that make spending the extra cash on this unit worth it. I even feel it's a better deal than the Apogee Duet 2. If you're thinking about buying the Audio Express, stop hesitating. You won't regret it one bit.
