3.5 TIME CODE CHASE INTERFACE
The AI-2 has a high resolution bi-directional time code reader that
has been specifically designed for time code chase applications.
The reader can read all time code types, at any rate, including
discontinuous high speed code. The AI-2 thereby ensures that
ADAT tape recorders can be integrated into a system when only a
time code feed is available. The AI-2 reader has a wide input range
and an adjustable flywheel option to cater for bad time code. The
reader input can also be selected as the system reference when it
is necessary for the ADAT to lock to unreferenced or off speed
code.
Connect the RDR IN connector in the reference section of the AI-2
rear panel to the reference or master time code with a standard
mono or stereo jack plug cable.
In time code chase mode an optional video sync or word clock
reference may be connected. If an external reference is supplied,
the AI-2 will resolve the ADATs to the reference, while using the
time code input as a numerical reference only.

CAUTION: TO PREVENT ELECTRICAL SHOCK DO NOT REMOVE COVERS. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE
HARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPTERATIONS.
Similar precautions apply, when using an external word clock, as
for the previous methods of operation. The word clock must be
locked to either the video reference, if used, or to the time code
which is being fed to the reader input.
