Master clock frequency display
Indicates the frequency (44.1 kHz or 48 kHz) of the currently-selected master clock. If
the unit is not synching to the master clock, “UNLOCK” will appear.
NOTE
• If sample rate pull-up/down has been specified in the Dante
Controller application, this area indicates the change in the
sample rate as a percentage, such as -4.0%, -0.1%, +0.1%, and
+4.1667%.
• To change the master clock when sample rate pull-up/down has
been specified, disable the pull-up/down in the Dante Controller, change the master clock, then
specify pull-up/down again.

Master clock select buttons
Use the buttons to select the clock source that you want to use as the word clock master
from the following options:
• INT 48 k
• INT 44.1 k
The QL console internal clock (sampling rate 48 kHz or 44.1 kHz) will be the clock
source.
• WORD CLOCK IN
The word clock supplied from the WORD CLOCK IN jack on the rear panel of the console
will be used as the clock source.
• DANTE 48k
• DANTE 44.1k
The word clock supplied from the Dante jack on the rear panel of the console will be
used as the clock source.
NOTE
With QL V1.07 and later, if you initialize the console to factory settings, the default value for the
word clock is set to DANTE 48k. This allows you to synchronize word clock even when using
multiple CL and QL consoles at their default settings.
• SLOT 1–2
The word clock supplied via a digital I/O card installed in a console slot will be used as
the clock source. Word clock can be selected in pairs for each slot.
3
Clock status Indicator
Indicates the console's status as a master or a slave in the Dante audio network.
NOTE
When
is displayed and the specified word clock is not synchronized
with a device acting as a Dante master, the audio might cut out.
4
Clock status display
Indicates the status of synchronization with the master clock for each clock source. Each
indicator is explained below:
• LOCKED (light blue)
Indicates that a clock synchronized with the selected clock source is being input. If an
external device is connected to the corresponding connector or slot, input/output is
occurring properly between that device and the QL series console. If the sampling
frequency is close, this status may be displayed even if not synchronized.
• LOCKED, BUT NOT SYNC’ED (yellow)
A valid clock is being input, but is not synchronized with the selected clock source. If an
external device is connected to the corresponding connector, input/output cannot
occur correctly between that device and the QL series console.
• SRC ON (green)
This is a special status that applies only to SLOT1–2, indicating that the corresponding
channel’s SRC (Sampling Rate Converter) is enabled. This means that even if the signal
is not synchronized, normal input/output with the QL series console is occurring.
• UNLOCKED (red)
A valid clock is not being input. If an external device is connected to the corresponding
connector, input/output cannot occur correctly between that device and the QL series
console.
