SYS/W.CLOCK function
220 PM5D/PM5D-RH V2 / DSP5D Owner’s Manual Reference section
Note
•For the DSP5D, you cannot select 2TR IN D1–D3 or SLOT
3–4. For CASCADE IN, you can choose either the D-sub 68-
pin connector or the RJ-45 connector.
•If you make cascade or other connections using the
DCU5D’s CASCADE OUT (RJ-45) connector, it will not be
possible to synchronize to the word clock from the DCU5D’s
CASCADE OUT (D-sub) connector. In this case, you’ll need
to provide a separate connection for the word clock.
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.
BFs (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).
CSlot number / Card type
This area shows the type of digital I/O card installed in
slots 1–4.
DINPUT FORMAT (Input signal format)EOUTPUT FORMAT (Output signal format)
Select one of the following as the method by which sig-
nals will be exchanged with a digital I/O card installed
in the slot when the PM5D is operating at a high sam-
pling rate (88.2/96 kHz).
• SINGLE
This setting allows transmission/reception of the nor-
mal number of channels when existing equipment that
operates at 44.1/48 kHz is connected. The sampling
rate will be converted for each channel of the digital I/
O card, and transmitted/received at half the sampling
frequency (44.1/48 kHz) of the PM5D. (This setting
can be selected only for slots in which a digital I/O card
that does not support 96 kHz is installed.)
• DOUBLE SPEED
This setting allows high sampling rate audio signals to
be transmitted/received without change when equip-
ment that operates at a high sampling rate (88.2/96
kHz) is connected. (This setting can be connected only
for slots in which a digital I/O card that supports 96
kHz is installed.)
• DOUBLE CHANNEL
This setting allows high sampling rate (88.2/96 kHz)
audio signals to be handled when existing equipment
that operates at 44.1/48 kHz is connected. Two chan-
nels of signals at half the PM5D’s sampling frequency
(44.1/48 kHz) are transmitted/received together as a
high sampling rate monaural signal. (The number of
usable channels will be half.)
FFREQUENCY (Sampling frequency)
This indicates the sampling frequency of the signal
being input to each channel of the digital I/O card, in
sets of two channels.
GSRC (Sampling Rate Converter)
This button switches the Sampling Rate Converter on/
off, in sets of two channels. This is available only for
slots in which a digital I/O card with a built-in sam-
pling rate converter is installed.
HEMPHASIS STATUS
This indicates whether emphasis is applied to the input
signal, in sets of two channels. This is available only for
slots in which a digital I/O card is installed.
