MOTU 16A Audio Interface 
32x32 I/O with 16x16 TRS analog, 48-ch mixing, DSP & AVB-TSN networking

The MOTU 16A is one of several new high-performance audio interfaces from MOTU that combine superb audio quality, large console style mixing, and state-of-the-art features. Featuring 64 Audio Channels. It is a feast of analog and digital I/O. Sixteen balanced/unbalanced TRS analog inputs and outputs, plus 2 x 8-channel ADAT optical ports, deliver a total of 32 inputs and 32 outputs. Use the 16A for expanded analog I/O for your computer, or as a flexible, comprehensive patchbay and mixer. Or both! Superb audio quality. Pure sound, without compromise. The MOTU 16A 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 16A 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 16A, the answer is, not much at all. In the 16A, 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 16A 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 16A, 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 16A, plus the 48-channel mixer inside the 16A, plus audio network streams. The 16A 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 16A 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 16A interface is a future-proof investment in your studio.

48-channel digital mixing. Control up to 12 separate stereo mixes. The 16A 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 16A 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 & Compression. Vintage processing with 32-bit floating point precision. British analog mixing consoles are renowned for their musical EQ profiles. The 16A 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 16A'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. Connect up to five MOTU interfaces using a MOTU AVB Switch (sold separately). The 16A 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. Build a network with multiple interfaces and computers using standard AVB switches and 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 16A doesn't reside on your hard drive. It's a web app served from the hardware itself. This means you can control the 16A's on-board DSP, mixing, device settings, and network audio routing from the web app software running in 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. 

Stand-alone mixing with wireless control. Control everything from your iPad or iPhone. Connect an Apple Airport™ or other Wi-Fi router directly to the 16A with a standard Ethernet cable and control the 16A's powerful mixing and DSP effects from your smart phone or tablet, without a computer. Great for live sound mixing! 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 16A 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 16A 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.
