The Lucid ADA8824 (ADAT) Audio Interface is an eight-channel, 24-bit, A/D and D/A converter
intended for use with digital audio workstations. [For clarity the ADA8824 (ADAT) will be referred
to as the 8824 throughout the rest of this user’s guide.] The 8824 provides ADAT lightpipe connec-
tions, eight analog I/O channels, and eight AES/EBU digital I/O channels.
Designed specifically for Alesis lightpipe (fiber-optic) connections, the 8824 provides a plug and play
audio interface between your studio’s audio gear and the Apple Macintosh or Windows computers.
Created in a strategic partnership with Alesis Corporation, the 8824 delivers the flexibility and
performance you need for leading-edge audio production by providing eight channel digital transfers at
24-bit resolution. Digitally controlled attenuation of analog input and output levels and high-resolu-
tion LED metering help you realize the maximum dynamic range from your digital audio system.
Alesis pioneered the use of fiber-optic connections for digital audio transfer through its proprietary
format. The Alesis PCR card works on Macintosh and Windows computers and is compatible with
products from a wide range of vendors. The growing popularity of ADAT-equipped gear and the
introduction of the 8824 make it even easier for you to stay in the digital domain throughout most of
the production process.
The 8824’s analog I/O channels are equipped with XLR connectors, which accept or deliver either
balanced or unbalanced signals. The AES/EBU digital I/O channels use XLR connectors and the
lightpipe connections use TOSLINK connectors. The 8824 operates at +4dBu, -10dBV, and
intermediate signal levels.
We recommend that you read this manual from cover to cover. Somewhere between the confines of
the two covers you should find the answers to most of your questions, both technical as well as
musical. Please feel free to contact us if you have questions, comments or suggestions.
