The 1248 provides all 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.

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 123 dB dynamic range (A-weighted, 20 Hz to 20 kHz) on its balanced TRS analog outputs.

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 host software.

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 the first and only interface to combine Thunderbolt I / O connectivity with AVB audio networking.

Don't have a Thunderbolt-equipped computer yet? Hi-speed USB 2.0 provides across-the-board compatibility with pretty much all laptops and desktops. The 1248 is USB audio class compliant, which means you enjoy OS-level USB compatibility and support, including iPad support (with a camera connection kit). Since USB 2.0 devices are compatible with USB 3.0-equipped hosts, your 1248 interface is a future-proof investment in your studio.

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.

British analog mixing consoles and renowned for their musical EQ profiles. The 1248 meticulously models these classic EQs to give you the very same, magical EQ response found on there 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 levelling amplifier, known for its unique and highly sought-after Automatic Gain Control (AGC) characteristics.

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.

The 1248 network port includes 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.

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 in your favourite 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.

Connect an Apple Airport or other Wi-Fi router directly to the 1248 with a standard Ethernet cable and control the 1248's powerful mixing and DSP effects from your smart phone or tablet, without a computer. Great for live sound mixing.
