11.8TAPE OFFSET

This function is intended for offsetting individual M20s or ADATs from each other within a multi-ADAT system only, not for setting an offset from an external SMPTE time code master. For setting a SMPTE offset see section 11.6a.

This offsets (shifts in time) the master ADAT (ID1) compared to the slave ADATs, or individual slaves compared to the master. The offset can be referenced to ABS time code or between two locate points.

An offset-enabled slave is offset by the specified amount from the master machine. With offset enabled on the master, it is offset by the specified amount from all slave units (i.e., all slaves are offset by the negative amount compared to the master unit).

In Edit Tape Offset mode, the Up/Down buttons choose between (ABS) Time Code and Location.

If Offset Mode = Time code, the reference counter displays the offset amount (up to ±24 hours) in hours, minutes, seconds, frames, and subframes. (To edit the Samples field, select the Subframes field, then press the Cursor Right button.)
