The Motu 8M Thunderbolt Audio Interface offers flexible connectivity to a computer via its built in ultra-fast Thunderbolt technology or class compliant hi-speed USB 2.0. The 8M features 18 channels of perfect analog I/O combined with 32 channels of digital I/O which makes a total of 50 simultaneous audio channels. Motus 8M is perfect for studio use or even on stage. The Motu 8M Thunderbolt Audio Interface provides high quality sound to studios on a budget and a much more. The 8M produces a minuscule -110dB THD+N of self noise the 8M offers you some of the cleanest and crispest audio around. The 8M includes 8 incredibly transparent and crystal clear microphone preamplifiers that include Motus V-Limit protection which offers a 9dB buffer to prevent digital clipping. An extra 16 channels of digital I/O via ADAT optical ports brings your complete channel count to 24 x 24. To go with this collection of high-quality I/O Motu provided the 8M Interface with ultra-fast Thunderbolt connectivity (as well as USB 2.0) so you get incredible low system latency. Motus 8M Audio Interface features an onboard DSP mixer which offers a number of advantages that will be useful in a variety of scenarios. This digital mixer supports up to 48 inputs (via AVB expansion) and 12 stereo busses which allows you to set up complex routing schemes completely independent of your computer. If connected to a wireless router the 8M can have all of its internal mixing functions including effects and processing accessed via an app on your iOS device allowing your 8M to function perfectly as a standalone mixer. Also included is DSP EQ compression gate and reverb which will serve many purposes in the studio or on stage. The Ethernet connection within the 8M can link more Motu AVB equipped audio interfaces to it. This can be done directly via a simple Ethernet cable or as part of an audio network via one or more Motu AVB Switches. If you use a single Ethernet cable you can easily link a second 8M or other AVB ready device directly to your first one. With Motu AVB Switches you can create an audio network of up to five units potentially linking hundreds of channels of I/O across multiple rooms. And since its all over standard Cat-5e Ethernet cable latency or cable runs arent any kind of issue.
