The LS-ADAT is a full-function ADAT interface that provides two ADAT lightpipe inputs and outputs and an ADAT Sync In Port for the LynxTWO and Lynx L22 professional PCI cards. Operating at a sample rate of 48 kHz, the LS-ADAT I/O channel capacity is 16. Higher sample rates are supported using S/MUX technology: 8 channels at 96 kHz and 4 channels at 192kHz.

The ADAT Sync In port feeds on-board time code control logic that provides two methods of sample-accurate synchronization. In systems using ASIO compatible audio applications, the LS-ADAT utilizes Steinberg's ASIO Positioning Protocol for synchronization to ADAT time code. Alternatively, synchronization using the LS-ADAT's cue point capability initiates recording or playback with sample period resolution. The LS-ADAT can also transmits time code via MTC for general compatibility with many applications.

The LS-ADAT offers a wide variety of sample clock synchronizations options. Its sample clock source can be derived from a word clock or composite video received by the LynxTWO. In addition, either lightpipe input or the Sync In port can also be selected as the clock source.
