MOTU 1248 Audio Interface
32x34 I/O with 4 mic in, 8x12 TRS, 48-ch mixing, DSP and AVB-TSN networking

The 1248 is the flagship interface for a new line of high-performance audio interfaces that combine superb audio quality and state-of-the-art features. 

66 audio channels. All the I/O you need in one rack space. 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 

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 123 dB dynamic range (A-weighted, 20 Hz to 20 kHz) 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 host software. Over Thunderbolt, round trip host latency is an impressive 1.4 ms, from analog in, through the host, to analog out (@ 96 kHz with a 32-sample host buffer). 

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 the first and only interface 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 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.
