When you change the word clock settings, noise may
be heard from the output jacks of the CS1D and AO8,
particularly if an MY8-AT digital I/O card is installed
in the DIO8. To protect your speaker system, you
must turn down the power amp output before
changing the word clock settings. Such a change in
the word clock settings can occur not only when
PM1D system internal settings are changed, but also
when the word clock setting is switched on an exter-
nal device (e.g., a CD player or a recording device).
Hint
In the case of one console and two engines connected
in a Mirror configuration, there will also be an
Engine B select button, allowing you to make set-
tings. However, the settings of engine A and engine B
will be linked.
• ENGINE A (DSP1D-EX {DSP1D})
INT 48 k
Internal clock of engine A (48 kHz)
INT 44.1 k
Internal clock of engine A (44.1 kHz)
W.CLOCK IN
Word clock supplied to the WORD CLOCK IN
connector of engine A
• ENGINE B (DSP1D-EX {DSP1D})
INT 48 k
Internal clock of engine B (48 kHz)
INT 44.1 k
Internal clock of engine B (44.1 kHz)
W.CLOCK IN
Word clock supplied to the WORD CLOCK IN
connector of engine B
If the ADVANCED button is on, the clock source
can be selected from the following devices, as well
as from engines A/B listed above.
• UNIT
ENGINE A
CH 1/2, CH 3/4, CH 5/6, CH 7/8
The word clock included in the input signal for
each channel of the digital input/output unit
(DIO8) connected to engine A.
ENGINE B
CH 1/2, CH 3/4, CH 5/6, CH 7/8
The word clock included in the input signal for
each channel of the digital input/output unit
(DIO8) connected to engine B.
The only clock source that can be selected as the
master is the clock that is extracted from the digital
I/O card installed in slot number 1 of unit
number 1.
If the digital I/O card type is MY8-AE (AES/EBU
format), you can also use the 1/2–7/8 buttons to
select the input channel.
If the type of digital I/O card is MY8-TD (Tascam
format) or MY8-AT (ADAT format), operation will
be the same regardless of which of the four buttons
you select. In the case of an analog card such as the
MY8-AD or MY4-AD, the status will always be
UNLOCK, and operation will not be correct even if
you select this.
• CONSOLE
INT 48k
Internal clock (48 kHz) of the console (CS1D)
INT 44.1
Internal clock (44.1 kHz) of the console (CS1D)
W.CLOCK IN
Word clock supplied to the WORD CLOCK IN
jack of the console (CS1D)
2TR IN
Clock extracted from 2-TRACK IN DIGITAL AES/
EBU jack 3 of the console (CS1D)
3 WORD CLOCK INPUT SELECT (displayed only if
ADVANCED level is selected)
For each device within the PM1D system, you can
specify the jack that will supply the word clock used
for synchronization.
This button will be displayed only for a unit that is
connected or virtually connected. Buttons for a unit
that cannot be controlled will be grayed out, and the
setting cannot be changed.
For each device, you can select one of the following
three settings.
• If the AUTO button is on
A valid word clock will automatically be detected in
the priority order of the WORD CLOCK IN connec-
tor of that device → the 68 pin D-sub connector con-
nected to the engine, and the connector that receives
the word clock will be specified accordingly. How-
ever if, while the unit is operating on the word clock
supplied from the 68 pin D-sub connector, a word
clock valid for synchronization begins to be received
from the WORD CLOCK IN connector, the word
clock source will automatically switch to the WORD
CLOCK IN connector.
Hint
This automatic detection is always enabled. This
means that even if one of the clocks should be inter-
rupted, the clock source will be switched immedi-
ately to re-establish synchronization.
• If the W.CLOCK button is on
If this button is on, the WORD CLOCK IN connec-
tor of that device will be selected.
