Mytek Digital Stereo 96 ADC (VER.7/sep 2010) - Manual (Page 11)

6. Synchronize the destination either to digital input sync or to
wordclock sync, depending on system configuration. The quality of
recorded signal does not depend on how the digital destination is
synchronized with Mytek AD converter.
7. Record- adjust input level by adjusting level at the source. Unless you
are printing final CD master, we do not recommend recording too hot.
There is no sonic benefit of pushing the level up to 0dBFS. A healthy 1-
2-3 dBs headroom allows more freedom in later processing and mixing
of recorded tracks. The red peak light is triggered digitally when 1 or
more samples are overload. It's not recommended to peak frequently
although occasional overloads might be acceptable.
