The Most Powerful UltraLite Ever

With 18 inputs and 22 outputs, the MOTU UltraLite-mk4 audio interface packs a lot of I/O for its size. Optimized drivers ensure impressively low latency, while 24-bit/192kHz-quality audio gives rise to excellent-sounding recordings. You'll enjoy large console-style mixing with 48 channels and 12 stereo buses, by virtue of the UltraLite-mk4's powerful DSP mixer. Incredibly flexible matrix routing quickly patches inputs to outputs, or splits inputs to multiple destinations, and onboard 32-bit floating point processing provides you with modeled vintage effects. The MOTU UltraLite-mk4 audio interface can also be controlled wirelessly with your smart device or computer, making it ideal for mobile mixing.

Fantastic sound quality and exceptional routing versatility

One reason the MOTU UltraLite series has been so popular and well loved here at Sweetwater is the fact that these interfaces sound incredible while remaining extraordinarily versatile. You can record up to 24-bit/192kHz-quality audio with impressively low latency, and the UltraLite-mk4 offers a pair of combo mic/line/hi-Z inputs, six line-level inputs, 10 analog outputs, headphone out, S/PDIF, and ADAT for a total of 18 inputs and 22 outputs. Best of all, the UltraLite-mk4's onboard DSP routes signals with no latency and no processor strain on your computer.

Powerful built-in effects and routing

With built-in effects and DSP routing, the MOTU UltraLite-mk4 dials in great headphone mixes without taxing your computer. The effects include British EQ, vintage compression, and classic reverb. Of special note, you'll appreciate the accurate model of the legendary LA-2A optical compressor, which provides vintage, musical automatic gain control. These aren't just ho-hum effects — these are great-sounding tools you can use to create wet headphone mixes while you keep a dry monitor mix. But if you want, you can record your signals wet, so you don't have to waste CPU on effects later down the line. You can also inspect your audio with advanced diagnostic tools, including a real-time FFT display, spectrogram, oscilloscope, X-Y plot, and phase analyzer.

It's great for mobile mixing too

Take the UltraLite-mk4 to your next gig, and use it as a regular mixer, complete with effects. Control its powerful DSP mixer and effects from a connected laptop, or wirelessly with your smart device — or multiple smart devices — on a shared Wi-Fi network with the computer.

I love the new software manager it's verintuitive

Great Product / Great Support

I purchased this interface to support a live multitrack recording setup, using a MacBookPro as the keyboard rig and wanting to route different VI channels in Live to separate analog and digital audio outputs on the MOTU. I encountered two issues, one was clearly an older MBP that couldn't keep up with higher sample rates, the other was a legacy MIDI driver that caused a conflict with the MOTU MIDI driver. In both cases, MOTU support was right there with me making sure I had the info I needed. The MIDI issue was the most difficult, but was resolved in 1-2 days. This is a very solid product, both mechanically and architecturally. On an previous smaller audio interface, I used a pair of analog outputs/inputs and short TRS cables to provide a loopback requirement Now, the MOTU interface permits me to create virtual outputs and inputs and even patch them virtually. As I move the interface from Mac to Mac, those settings are remembered by the hardware - superb. Highly recommended and well though out product.
