Connect a time code source to the reader input, the time code sup-
plied should be between zero and forty five minutes. Put a format-
ted tape in the first ADAT transport and press the AI-2 ONLINE
Key. Now start the time code source, the ADAT will cue to the
reader time code position, go into play and lock.
Press the DISPLAY key until the position error is displayed, an
L and 0.00 will be displayed indicating that the ADAT transport is in
perfect synchronization with the reader time code. Rewind the time
code source, the ADAT will follow the time code, provided that the
AI-2 has received time code in wind.
4.5 SETTING AN OFFSET
An offset is used when the ADAT tape time is not coincident with
the time code that it must lock to. As it is unlikely that program
material on an ADAT tape will have the same time as the master
code, the AI-2 offset register can be used to compensate for the
difference between the two time codes.
There are three ways of setting an offset. The offset can be manu-
ally entered, captured or read from the ADAT tape header if it has
been previously saved to tape.
If the time code offset is known then use Set/Hold mode to manu-
ally enter it. Press the SET/HOLD key, the frames digits will start to
flash, press the SET/HOLD key again to select the required pair of
time code digits, then use the DOWN and UP keys to enter the
offset.
To capture an offset, play the ADAT transport to a known cue point
and press the STORE and SET/HOLD keys together. The AI-2
automatically calculates the difference between the reader input
and the ADAT tape time and enters it in the offset register. If
required Set/Hold mode can be used to enter or adjust a reader
time code position to a known value before using capture.
To set an offset from cue times stored on tape, set use times to on
in the AI-2 Cue menu and then select a cue number, the offset will
be calculated by subtracting the ADAT Tape time from the Cue start
time. See Using Cue Times, for more information on using cue
times.
