M-AUDIO Lagoon - Manual (Page 4)

Introduction
Congratulations on your purchase of a LAGOON PCI Digital Audio Card! With this card,
high-quality digital audio processing becomes possible with your PC. The card offers
optical digital I/O and an ADAT Sync connector (standard Alesis 9-pin DB connector).
The optical digital I/Os may be software-configured to S/PDIF or ADAT mode while
supporting Full Duplex for simultaneous record and playback (e.g. simultaneous
recording from ADAT and playing back over S/PDIF is possible) The S/PDIF mode
supports several sample rates and sample resolutions up to 24 Bit at 96 kHz. Using ADAT,
you may record and play back simultaneously 8 channels of digital audio at up to 51 kHz
and 24 Bit. Using the ADAT Sync, synchronization to your ADAT recorder is easy. If this
is not needed, this connector can alternately be used as a MIDI In/Out interface by simply
plugging in the included MIDI adapter cable.
Beyond these versatile interfacing possibilities the Motorola 56301 DSP used on this card
offers 80 MIPS of DSP computing power. Combined with 768 kBytes of fast EDO
DRAM, a variety of audio effects may be run on this system with simultaneous digital I/O
operation.
