The 112D is a flexible digital audio interface, router, format converter, and stand-alone mixer, with connectivity to a host computer through ultra-fast Thunderbolt technology, AVB Ethernet, or class compliant, high-speed USB 2.0 (compatible with USB 3.0 and iOS). The 112D provides 24 channels of AES/EBU digital I/O, 24 channels of ADAT optical digital I/O and 64 channels of MADI for a total of 112 simultaneous digital I/O channels. With near-zero latency, send any input to any output, or multiple outputs. Freely route all 112 audio channels to and from the computer over Thunderbolt, plus any devices on the AVB network. Convert any format to any other: AES/EBU, optical, MADI, AVB, and computer audio (Thunderbolt or USB). Powerful DSP delivers large console style mixing with 48 channels, 12 stereo busses, and 32-bit floating point effects processing, including modeled analog EQ, vintage compression and classic reverb. Use the 112D as a stand-alone mixer and control everything from the 112D's innovative web app running on your iPad, iPhone, tablet, smart phone, and laptop. Connect a second MOTU AVB interface (such as a 1248, 8M, 16A or 112D) with a simple Ethernet cable. Add more I/O with the MOTU AVB Switch (sold separately). Build an AVB audio network with multiple switches and sub-millisecond latency, even over long cable runs. Stream hundreds of channels among devices and computers on the network. From studio to stage, the 112D delivers flexible digital routing/conversion, state-of-the-art operation, and reliable performance.
