32-input Thunderbolt audio interface with 48-channel mixing and AVB networking capability.
MOTU interfaces can be found in studios around the world because of their superb performance record and trusted reliability. The 1248 is MOTU's flagship interface for their next-generation line of high-performance audio interfaces, combining incredible audio and state-of-the-art features.
66 audio channels - All the I/O you need in one rack space
The 1248 provides all of the I/O you need for a well-equipped personal studio, including four mic inputs, two dedicated hi-Z guitar inputs, 8 x 12 balanced analog with separate main and monitor outs, 2 x 8-channel ADAT optical, and RCA S/PDIF (with sample rate conversion), for a total of 32 inputs and 34 outputs. Need more I/O? Expansion possibilities are seamless and virtually limitless.
Superb audio quality - Pure sound, without compromise
The 1248 employs latest-generation ESS Sabre32 Ultra converters, known for their industry-leading performance, together with expertly engineered analog circuits that reflect more than three decades of pro audio engineering expertise. The result? The 1248 achieves actual, measured performance of 123dB dynamic range (A-weighted, 20Hz to 20kHz) on its balanced TRS analog outputs.
Ultra-low I/O latency - State-of-the-art latency performance
Every digital audio workflow has some latency. The only question is, how much? In the case of the 1248, the answer is, not much at all. In the 1248, latency is measured in a handful of samples, from the time an audio signal first goes digital to its arrival somewhere else (to an output the mixer, or the computer). By keeping latency this low in the hardware, the 1248 helps minimize latency introduced by your system.
Thunderbolt technology - Plug-and-play ease with massive bandwidth
Thunderbolt lets you connect displays, hard drives, and other peripherals to your computer, along with the 1248, and the Thunderbolt bus won't even break a sweat. But more importantly, Thunderbolt gives you an astonishing 256 channels of computer I/O (128 in and out). You can use them to route audio to the physical inputs and outputs on the 1248, plus the 48-channel mixer inside the 1248, plus audio network streams. The 1248 is one of the first and only interfaces to combine Thunderbolt I/O connectivity with AVB audio networking.
Audio class compliant USB 2.0 - Broad compatibility with future-proof connectivity
Don't have a Thunderbolt-equipped computer yet? Hi-speed USB 2.0 provides across -the-board compatibility with pretty much all laptops and desktop computers. The 1248 is USB audio class compliant, which means you enjoy OS-level USB compatibility and support, including iPad support (works with camera connection kit, sold separately). Since USB 2.0 devices are compatible with USB 3.0-equipped hosts, your 1248 interface is a future-proof investment in your studio.
48-channel digital mixing - Control up to 12 separate stereo mixes
The 1248 is equipped with a 48-channel digital mixer designed just like a large format mixing console. The 48 inputs can take signal from anywhere; the physical inputs on the 1248 interface itself, audio channels from host software on your computer, audio network streams, or even mixer outputs. The mixer provides 7 stereo aux busses, 3 groups, a reverb bus that can alternately serve as a 4th group, a Main Mix bus and a separate Monitor bus that can serve as a solo bus. In essence: capable and transparent mixing.
Modeled analog EQ and compression - Vintage processing with 32-bit floating point precision
British analog mixing consoles are renowned for their musical EQ profiles. The 1248 meticulously models these classic EQs to give you the very same, magical EQ response found on these coveted desks. Each input channel also provides a classic compressor module with optional peak/RMS operation. Groups and the Main Mix bus are equipped with MOTU's Leveler, an accurate model of the legendary Teletronix LA-2A optical leveling amplifier, known for its unique and highly sought-after Automatic-Gain Control (AGC) characteristics.
Matrix routing and splitting - Put the ultimate patch-bay at your fingertips
With one click on the 1248's routing grid, you can route any source signal to any destination. Sources can be analog or digital inputs on the interface, computer channels, mixer bus outputs, or audio network streams from other devices on the network. Destinations include interface outputs, host software inputs, mixer inputs, or any other device (or computer) on the AVB network. You can even split any single input (or stereo pair) to unlimited multiple output destinations.
System expansion and audio networking - Expand your system with more I/O and Wi-Fi control
The 1248 network port introduces AVB Ethernet, the new industry standard developed by the IEEE for professional audio networking. Add a second MOTU AVB interface (1248, 8M or 16A) with a simple Cat-5e or CAT-6 Ethernet cable.
Connect up to five MOTU interfaces using a MOTU AVB Switch (sold separately)
Build a network with multiple interfaces, computers, and AVB switches using standard network cabling, with ultra-low network latency, even over long cable runs (hundreds of meters). Stream hundreds of audio channels among devices and computers on the network.
Web app control - Control everything from your laptop, tablet, and smart phone
The software that you use to control the 1248 doesn't' reside on your hard drive. It's a web app served from the hardware itself. This means you can control the 1248's on-board DSP, mixing, device settings, and network audio routing from the web app software running on your favorite web browser on a laptop, tablet or smart phone connected by wire or Wi-Fi to your local area network. Use any web client on any platform - Mac, Windows, Linux, iOS, Android - as long as it shares the same network.
Comprehensive metering - View all I/O activity at a glance
The large backlit 324 x 24 LCD lets you view all signal activity at a glance with detailed metering for all analog and digital I/O. Access hardware settings from a simple and convenient menu.
Quick setup presets - Completely transform your MOTU interface with one click
The 1248 is so flexible, it can serve many roles - in the studio, on stage, and throughout an installation. The Quick Setup menu lets you instantly reconfigure the 1248 for many common situations, from operation as a standard audio interface to serving as a network "snake" from one location to another. Once a preset is chosen, you can easily customize the routing grid and mixer settings to further suit your specific needs - and then save your own custom presets.

Comments about MOTU 1248 Thunderbolt Audio Interface:
I've had my 1248 for about 3 months. I replaced a more "high end" interface with the 1248 -- ie the best interface used at our recording studio. I needed something with less noise and which would operate with a greater number of modern systems.
The pres are usable, the noise is extremely low, and the convertors are very clean. Overall, very transparent sounding. This was a bigger upgrade than I expected.
The 1248 also has very low latency, is easily expandable to include additional AVB interfaces, and has been super reliable.
MIDI would have been nice and sure, I can list a few minor things I would like to be different but the bottom line is this is a tool that doesn't fight me and always does its job well. Sounds great and works reliably. Keep up the good work, MOTU!
