If the words slipping or unlocked are in parentheses (as shown above for the ADAT
inputs), this means that the respective inputs are not routed (not connected to any inputs
and hence unused) and that the indication can be ignored.
Understanding the "System Sampling Rate and External Sync Indicator" When Using the
Internal 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
).
Of course, if you select one of the fixed rates (44.1 kHz, 48 kHz, 88.2 kHz, or 96 kHz),
the LED corresponding to your selection should light solidly.
The bottom LED, EXT, has four possible states:
Not lit at all: When the bottom LED is not lit at all, none of the digital inputs are routed.
This would happen only if the DSP A and DSP B inputs and the main outputs were
either unconnected or only connected to the analog inputs - no digital signals whatsoever!
Solidly lit: When the bottom LED is solidly lit, the sampling rates of all routed digital
inputs are locked to the internal clock rate and all is good. This should be the normal
state.
Blinking regularly: When the bottom LED is blinking regularly, at least one (and maybe
more than one) routed digital input is unlocked.
Use the right-hand side of the
clock menu page
in the SETUP area to see which digital inputs are
in fact
unlocked. As before, you can ignore
those in parentheses ( ).
Blinking irregularly: When the bottom LED is blinking irregularly, at least one (and
maybe more than one) routed digital input is "slipping" relative to the internal clock. Use
the right-hand side of the clock menu page in the SETUP area to see which digital inputs
are in fact slipping.
