The 8M Thunderbolt audio interface provides industry-leading dynamic range and large console style mixing. With 50 channels of audio I/O (24 ins and 26 outs), the 8M also supports USB 2.0 audio class compliant connectivity that is USB 3.0 compatible. Eight mic preamps are equipped with individual gain, pad and 48V phantom power, plus optional hardware-based V-Limit overload protection, which adds 9 dB of headroom above digital zero to prevent overs. 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. The unit's extensive routing grid patches ins to outs, or splits inputs to multiple destinations. Use the 8M as a stand-alone mixer and control everything from the 8M's innovative web app running on your iPad, iPhone, tablet, smart phone, and laptop. Connect a second MOTU AVB interface (1248, 8M or 16A) 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 initial tracking to final mastering, the 8M delivers superb sound quality, state-of-the-art operation, and reliable performance.
