1.1 INTRODUCTION
Thank you for purchasing the PreSonus EASERA GATEWAY. PreSonus Audio Electronics
has designed the EASERA GATEWAY utilizing high-grade components to insure optimum
performance that will last a lifetime. The EASERA GATEWAY is the most powerful record-
ing interface of its size, with the ability to record and playback four inputs and six outputs
simultaneously at 24-bit/96K sample rate.
Loaded with four analog inputs, including two PreSonus microphone preamplifiers and two
line inputs, six balanced analog outputs and MIDI I/O, the EASERA GATEWAY is ready to
go out of the box for professional-quality computer recording. For further flexibility, the
EASERA GATEWAY can be bus-powered by a six-pin FireWire connector or externally
powered by the included power supply. The EASERA GATEWAY is the perfect computer
recording system that gives you the power for professional quality recordings in the palm
of your hand.
We suggest that you use this manual to familiarize yourself with the features, applications
and correct connection procedure for your EASERA GATEWAY before trying to connect it
to your computer. This will hopefully alleviate any unforeseen issues that you may
encounter during installation and set up.
Thank you, once again, for buying our product and we hope you enjoy your EASERA
GATEWAY!
5.1 MICROPHONES
The EASERA GATEWAY works great with all types of microphones including dynamic, rib-
bon and condenser microphones. Dynamic microphones and ribbon microphones are gen-
erally lower output devices and require no external power source. Condenser microphones
are generally more sensitive than dynamic and ribbon microphones and typically require
external 48V phantom power.
NOTE: If you are using a ribbon microphone, please check the manual for the mic before
applying phantom power. Applying phantom power to some microphones could cause dam-
age to the microphone.
6.1 TROUBLE SHOOTING
Please note that many technical issues can arise when converting a standard computer
into a DAW (Digital Audio Workstation). PreSonus will only provide support for issues that
directly relate to the EASERA GATEWAY interface. It may be necessary to contact the
manufacturer of the computer, operating system and/or software to obtain additional techni-
cal support. PreSonus does not provide support for issues in regards to operating systems,
additional hardware or software.
Please check the PreSonus website,
www.presonus.com
regularly for software information
and updates, firmware updates, and technical support. Also, technical assistance may be
received by calling PreSonus at 225-216-7887 between the hours of 10 am and 8 PM
Central Time.
Pops and Clicks
The light on the front right panel of the EASERA GATEWAY is a clock (sync) indicator. It
lets you know if your unit is receiving word clock correctly. Word clock is the manner by
which digital devices sync frame rates. Proper word clock sync prevents digital devices
from having pops, clicks, or distortion in the audio signal (due to mismatched digital audio
transmission).
If the symbol is solid blue, this indicates that your unit is in sync with the computer.
If the light is solid red, this indicates that the EASERA GATEWAY does not have sync from
the computer and that the unit might not be connected properly.
If the unit is flashing red and blue, the unit is not receiving external sync. \
The three different light modes are repeated on the next page.
