MOTU M4 - The NEW 4-In/4-Out USB Audio Interface from MOTU with Studio-Quality Sound!
Excellent engineering is tradition - decades of experience, award-winning development, worldwide top hits, mega-star tours, primetime TV shows and music for blockbuster movies - all part of every MOTU audio interface.

Top-Tier Audio Quality
Equipped with the same ESS Sabre32 Ultra DAC technology used in high-end MOTU AVB audio interfaces, the M4 delivers an astonishing 120 dB dynamic range on its main outputs.
This is made possible by the high-quality ESS converters, which are also used on the headphone output. Crystal-clear preamps produce a measured -129 dBu EIN at the mic inputs. You’ll hardly find better sound quality in this price range.

Speed. Practically Latency-Free Monitoring
The M4 offers latency-free monitoring of live inputs (mic, guitar or line signals). MOTU’s ultra-fast USB driver enables a round-trip latency of 2.5 ms (32 sample buffer at 96 kHz).

Detailed Level Meters
When recording and mixing, nothing is more critical than hitting optimal levels. The M4 is the only audio interface in its class with a 160 x 120 pixel full-color LCD display showing clear, detailed level meters for all inputs and outputs. You won’t find a better or more precise level display.

Loopback
The M4 driver offers a loopback function that lets you route the computer output back into your recording software. Streaming and podcasting have never been easier or better!

Stand-Alone Operation
With a standard USB-C power supply, the M4 can be used as a standalone preamp and basic mixer without a host computer. Simply activate the monitor button for each input (and 48V phantom power if needed) and adjust the preamp as required. Connect the main outputs to any device with line input, such as active speakers or a mixer.
All Included. Ready to Go. Workstation Software, Virtual Instruments and Loops

Connect the M4 to your Mac or PC and create your tracks with the included music production software Performer Lite or Live Lite. Also included are hundreds of loops, one-shots and sounds from leading manufacturers like Big Fish Audio, Lucidsamples and Loopmasters. Just register your purchased M4 at MOTU and download the full pro software immediately. Find the link here
MOTU Performer Lite
Performer Lite offers everything you need for quick and easy recording, editing, mixing and mastering your own music. Connect your mic, guitar and MIDI keyboard and start your own music production with dozens of effect plug-ins, guitar effects and more.

100+ Virtual Instruments

Loops and Sounds
You get over 6 GB of free loops and sample packs from MOTU, Big Fish Audio, Lucidsamples and Loopmasters. Choose from dozens of music styles and drag & drop them into your project - giving you the perfect backing for your recordings.
Includes Professional Stereo Headphones
The KH-238 delivers a full, balanced sound with rich bass and clear highs. It offers plenty of volume yet clean and precise stereo imaging. Naturally, the soft padded, wide headband is length-adjustable. The extension offers 12 steps per side for optimal fit. For even more comfort, the ear cups are mounted on two-axis pivots. The thick, soft padding of the circumaural cups also provides good external noise isolation.
The in-cable volume control is always at hand, making usage with PC or mp3 player easier. The 3.5 mm stereo jack plug delivers excellent transmission properties and a 6.3 mm stereo jack adapter is also included.
The M Series - Best in Class. Audio Quality, Speed and Level Meters!
