Description Introduced at NAMM in January 2000, EMI 2|6 was the first USB-based multi-channel audio interface. EMI in conjunction with Logic Audio formed a tightly integrated system: an affordable one-stop solution for the traveling musician. Mobility was the key aspect here: laptop, EMI, software, go!
At the time the project was started, no suitable solutions existed to build a USB audio interface featuring more than two channels of audio and external synchronization. Therefore, the solution was customized with Cypress‘ EZusb chip to interface with USB plus an FPGA implementing the complete audio data path. In addition to the hardware development, we had to teach the major OS vendors how to implement external synchronization with USB, as no other device did that before. As before with Audiowerk, the concept was good enough to be closely copied by big brands in the MI market.
Between 2001 and 2003, more than 20.000 units of EMI have been sold, again a very welcome success for Emagic. Customers reached beyond musicians: DJs, home theatre users, multi-media presenters and all those users looking for a mobile audio solution.

- mechanical switch to select input (analog/ digital)
- USB 1.1 (12Mbps) interface, bus-powered
- drivers for Windows 9x/ Millennium/ 2k/ XP, Mac OS 9, Mac OS X
As a spin-off the EMI 6|2m was created. Main differences: 6 analog inputs, 2 analog outputs. Digital ports configurable as either SPDIF or MIDI I/O. Built-in USB hub. 8-in-4 mixer to create separate mixes for main outputs and phones. By moving even more functionality into the FPGA, the additional features could be implemented at roughly the same cost.
