We STRONGLY recommend that you read this document in

its entirety before installing your Lexicon Studio Core2.

Before installing Version 1.20 of the Lexicon Control Software, visit the
Lexicon Studio download area of our web site at
http://www.lexicon.com/downloads/studio/download.htm
to insure that you are installing the most updated version of this product.
(All driver updates are free of charge.) We continue to enhance Core2
with new features and fix problems that arise with updates for most audio
software applications and highly recommend you install our latest drivers.
Also, be sure to check the Lexicon Studio areas of our Support Knowledge
Base in the Support area of the web site
http://www.lexicon.com/kbase/kbase.asp. The Support Knowledge Base
is reviewed and updated on a regular basis.

Please follow the Installation Instructions included inside the Core2 box for
proper installation of the Core2 PCI card and software drivers.

When working with your Core2 card or other cards in your computer, be
sure to use the anti-static wrist strap included with your Core2 and follow
all anti-static precautions noted in your Owner's Manual or Installation
Instructions.

We highly recommend that you familiarize yourself with your computer.
Identify the other cards in your system and make a list of them and the slot
numbers that they occupy. Be sure to install your Audio application soft­ware prior to installing the Lexicon Studio Core2 drivers.

NOTE: This document is available on your V1.20 CD-ROM as "Lexicon
Release Notes V1.20.PDF".

Lexicon Studio Core2 Tips & Troubleshooting

Low Latency Option

Note: This option may limit the number of busses you can enable simulta­neously, and will create a higher CPU load on your audio application. You
must reboot your computer after enabling this option.

Clock Restoration Time

Note: In some circumstances, Core2 may take some time to re-acquire lost
or rapidly switched clock sources.

Note: Any changes made in the Core2 I/O should be made when an
audio application is not running. If the Core2 I/O needs to be changed
during an audio session, save your work and quit the application. Make
the changes in the Core2 I/O then re-launch the audio application.

No Audio Through Punch Record

Note: For any channel that you wish to use in Punch Mode, you must
enable it in a running audio application as well as selecting it in the Punch
record panel of the Lexicon Core2 Control Panel.

Routing buttons are disabled in the Lexicon Core2 Control Panel

Note: Lexicon Studio software does not allow you to change your I/O
setup while an audio application is running. To change your I/O setup, quit
your audio application, run the Control Panel by selecting it from the
Control Panels menu, make your I/O changes, and re-launch your audio
application.

Mac Core2 V1.20 Application Notes

ASIO-compatible only; not Sound Manager-compatible

Logic Audio (Emagic)

Sample Rate changes
Issue: Distortion may occur after switching from 44.1 kHz to 48 kHz.
Solution: Logic Audio opens all available streams. If you get distortion

after changing from 44.1 to 48 kHz, you may need to reduce the number
of channels in the Core2 I/O or configure Logic Audio to use fewer audio
streams in the "Audio Hardware and Drivers" dialog.

Logic Audio has a number of issues that you should be aware of that are
not Core2 related:
A. In some earlier versions, Logic Audio did not support audio files at 48KHz
sampling rate.
B. Scrolling quickly through windows in Logic can interrupt audio and
cause performance problems.

Peak 2.10 (BIAS)

While it is possible to play audio from Peak 2 through the Core2, at this time
Peak 2.10 does not record audio with the Core2. However, audio files can
be imported, edited and, played back. Future updates of Peak 2.10 will
address this issue.
Note: At this time the output labels have an extra odd digit next to each
output pair. This is simply a cosmetic issue.

TC Spark (TC Works)

Spark is not certified to be compatible with the Core 2 card. This will be
addressed in a future version.
