Understanding the "System Sampling Rate and External Sync Indicator" When Using the
External Clock
The "System Sampling Rate and External Sync Indicator" is the box of five LEDs
immediately to the left of the display. The top four
LEDs indicate the status of
the system sampling rate:
Solidly lit: When one of the top four LEDs is solidly lit, the system sampling
rate is exact (+/- 0.05%) (the LED corresponding to the system sampling rate will
illuminate ).
Blinking: When one of the top four LEDs is blinking, the system sampling rate
is between one of the fixed rates (the LED corresponding to the nearest sampling rate will
blink ).
Use the "
Sample Rate" field on the clock
menu page in the SETUP area to see the actual
sampling rate (e.g., 48001Hz in the example to
the right).
The bottom LED, EXT, has two possible states:
Solidly lit: When the bottom LED is solidly lit, all of the routed digital inputs are locked
and all is right with the world.
Blinking regularly: When the bottom LED is blinking regularly, at least one (and maybe
more than one) routed digital input is unlocked (i.e., not synchronized to the external
clock). Use the right-hand side of the clock menu page in the SETUP area to see which
digital inputs are in fact unlocked.
To check which digital inputs are routed, consult the routing menu pages discussed in Routing Configuration
on page 53.
