SYS/W.CLOCK function
Here you can select the word clock on which the PM5D
will operate. You can also view and edit settings for cards
installed in slots 1–4.
A MASTER CLOCK SELECT
As the master clock to use, you can select the internal
clock or an external clock input from a connector or
slot. This setting determines the sampling frequency at
which the PM5D will operate. You can select the fol-
lowing items.
The operational status of each clock is shown by the
color of the symbol at the left of each button. Each
color has the following significance.
• LOCK (blue)
This indicates that a clock synchronized with the
source selected in (
2) is being input. If an external
device is connected to the corresponding connector or
slot, input/output is occurring normally between that
device and the PM5D. If the sampling frequency is
close, this status may be displayed even if not
synchronized.
• UNLOCK (red)
A valid clock is not being input. If an external device is
connected to the corresponding connector, input/out-
put cannot occur correctly between that device and the
PM5D.
• LOCK, BUT NOT SYNC’ED (orange)
A valid clock is being input, but is not synchronized
with the clock source selected in (
2). If an external
device is connected to the corresponding connector,
input/output cannot occur correctly between that
device and the PM5D.
• UNKNOWN (yellow)
This indicates that the clock status cannot be detected
because no external device is connected or because
there is no valid clock input. You will be able to select
this connector/slot, but successful synchronization can-
not occur until a valid connection is established.
• SRC ON (green)
This is a special status only for SLOT 1–4 and 2TR IN
2TR IN D1–3, indicating that the corresponding chan-
nel’s SRC (Sampling Rate Converter) is enabled. This
means that even if the signal is not synchronized, nor-
mal input/output with the PM5D is occurring.
Note
• Noise may occur at the output jacks when the word clock
setting is changed. In order to protect your speaker system,
be sure to turn down the power amp output before changing
the word clock setting.
• If you attempt to select a channel whose SRC is on as the
word clock master, a message will appear, warning you that
the sampling rate converter will be disabled.
B Fs (Sampling frequency)
This indicates the sampling frequency at which the
PM5D is operating. This will indicate “UNLOCKED”
while synchronization is lost (such as immediately after
switching the master clock).
