DIGITAL CLOCK SYNCHRONISATION
When clocking the D62 from an external, master clock source, there are two possible
methods of termination. When using the TEAC
® TDIF-1 Digital Interface protocol, which
uses a 25 pin D-sub connector system, or ADAT
® optical system, the Input Select button
should be in the Out position. Alternatively, external synchronisation may be achieved
via the 75Ω BNC connector, in which case the Input Select button should be set to its IN
position. The operation of the D62-A version is identical, except that the multitrack
interface is ADAT. When the unit is suitably connected, observe the Input Select LED
status to confirm the following clock conditions:
z The LED will illuminate brightly and steadily if a reliable and compatible clock
source is recognised.
 The LED will blink when External Clock is selected on the front panel, but no
external clock is detected.
' The LED will flicker dimly if the clock signal is inadequate due to problems such
as level matching or signal corruption. Typical causes of such problems are: the
connected cable is too long or of an incorrect type; the external clock signal has
deteriorated in quality to a point where it cannot be read reliably.
When External Clock is selected on the front panel, a reconstituted version of the input
word clock is available at the Word Sync Output BNC connector.
