1 Introduction
Thank you and congratulations on your purchase of the Emagic
EMI 2|6. You now own an innovative audio device that equips
your Macintosh or Windows PC with high-quality analog and
digital audio connectors.
The EMI 2|6 connects to any of your computer’s USB ports. Its
addition to your system doesn’t require opening the computer,
nor does it require an external power supply, as power is sup-
plied by the Universal Serial Bus (USB) itself. These features
make the EMI 2|6 an ideal audio interface for Windows lap-
tops, Powerbooks or iBooks, and also very convenient when
used with desktop computers.
As all electronic circuitry is physically placed outside the com-
puter, the risk of undesirable electronic interference is drasti-
cally reduced. This ensures exceptionally clear and clean sound
from the EMI 2|6 and maximizes the potential of its high-qual-
ity 24 bit converters.
In addition to its hardware design, we have taken great care
with the EMI 2|6 driver software. This ensures that latency is
minimal, making the EMI 2|6 an ideal audio interface for tasks
such as the realtime monitoring of software synthesizers, for
example.
This manual explains the set up procedure for the EMI 2|6 and
offers some application examples. Please read it carefully in
order to make the most of your EMI 2|6.
As this manual is cross-platform, much of the information
applies equally to both Windows and Macintosh systems.
Where information is Macintosh or Windows-specific, it will be
indicated by the topic or section header, or by use of the icons
shown to the right.
We wish you years of fun and productive work with the
EMI 2|6.
