1. Introduction
Thank you for choosing the ESI ESU1808.
ESU1808 shows the latest audio interface technology for external usage on notebook and desktop
computers. The USB 2.0 Hi-Speed audio interface for Mac & PC shows what is really possible with
USB 2.0. ESI's new USB 2 Xtreme technology boosts USB audio to a new level, providing better
performance for better results.
The 1U rack unit comes with not less than 18 input channels, 2 of them are high quality microphone
preamps with balanced XLR inputs and +48V phantom power, 2 of them allow a direct connection
of instruments (Hi-Z), 4 line inputs on the front for unbalanced and 8 line inputs on the rear for
balanced signals and there is a coaxial S/PDIF input. There are 8 balanced analog output channels,
one channel pair is also provided as coaxial S/PDIF output. Last but not least ESU1808 comes with
a MIDI I/O port providing 16 input and 16 output channels.
All this makes ESU1808 a product that defines new standards for USB audio for professional
applications. Never before you have seen this number of I/O channels on a USB audio product in
this price range.
