EFFECT GEQ SCENE MIDI/GPI/TC • If both buttons are off The 68 pin D-sub will be selected. 4 Status The symbol at the left of the button indicates the clock status that is being input to that connector. This indicates the result of selecting the connector, and whether audio signals of that status are being correctly input/output between the various devices. The various statuses have the following significance. • LOCK (blue) A clock synchronized to the source selected in 2 is being input. If the clock of the selected connector displays this status, the device to which that connector belongs is correctly performing input/output within the PM1D system. This status may be displayed even when unsynchronized, if the sampling frequency is close. • UNLOCK (red) A valid clock is not being input. If the clock of the selected connector has this status, the device to which that connector belongs is unable to function with that clock. As a result, that device is operating with its own clock, and therefore unable to input/output correctly within the PM1D system. A clock that is synchronized with the source selected in 2 must be input to the selected connector. • LOCK, BUT NOT SYNC'ED (orange) A valid clock is being input, but is not synchronized to the source selected in 2. If the clock of the selected connector has this status, the device to which that connector belongs is unable to correctly perform input/output within the PM1D system. A clock that is synchronized with the source selected in 2 must be input to the selected connector. SYS/W.CLOCK (system/word clock) function • UNKNOWN (yellow) This indicates that the clock status of that connector cannot be known, because it is a virtual connection or is unconnected. Although it is possible to select this connector, valid synchronization with the PM1D system cannot be established until an actual connection is made. • SRC ON (green) This is a special status belonging only to 2-TRACK IN DIGITAL connector 3. The clock status is "LOCK" or "LOCK, BUT NOT SYNC'ED", but since an SRC (Sampling Rate Converter) is provided on the audio input section, the audio is being input normally into the PM1D system by virtue of this function, even if it is actually not synchronized. In order for the PM1D system to operate correctly, the status of the selected connectors must all be in the LOCK (blue) state. If the 2-TRACK IN DIGITAL connector 3 SRC is on, and you attempt to select this connector as the word clock master, a message of "Selecting 2TR IN 3 will turn off SRC. Are you sure?" will be displayed. When you click the OK button, the SRC will be defeated. When using an MY8-AT card to handle ADAT format signals, synchronization may tend to be lost easily, depending on the device that is connected. For more reliable synchronization, we recommend that the word clock for the combination of digital audio equipment you are using be taken from other than the ADAT format connector.

SYS/W.CLOCK
SYS/W.CLOCK (system/word clock) function
55
If both buttons are off
The 68 pin D-sub will be selected.
4
Status
The
symbol at the left of the button indicates the
clock status that is being input to that connector.
This indicates the result of selecting the connector,
and whether audio signals of that status are being
correctly input/output between the various devices.
The various statuses have the following significance.
LOCK (blue)
A clock synchronized to the source selected in
2
is
being input.
If the clock of the selected connector displays this
status, the device to which that connector belongs is
correctly performing input/output within the PM1D
system.
This status may be displayed even when unsynchro-
nized, if the sampling frequency is close.
UNLOCK (red)
A valid clock is not being input.
If the clock of the selected connector has this status,
the device to which that connector belongs is unable
to function with that clock.
As a result, that device is operating with its own
clock, and therefore unable to input/output correctly
within the PM1D system. A clock that is synchro-
nized with the source selected in
2
must be input to
the selected connector.
LOCK, BUT NOT SYNC’ED (orange)
A valid clock is being input, but is not synchronized
to the source selected in
2
.
If the clock of the selected connector has this status,
the device to which that connector belongs is unable
to correctly perform input/output within the PM1D
system.
A clock that is synchronized with the source selected
in
2
must be input to the selected connector.
UNKNOWN (yellow)
This indicates that the clock status of that connector
cannot be known, because it is a virtual connection
or is unconnected.
Although it is possible to select this connector, valid
synchronization with the PM1D system cannot be
established until an actual connection is made.
SRC ON (green)
This is a special status belonging only to 2-TRACK
IN DIGITAL connector 3.
The clock status is “LOCK” or “LOCK, BUT NOT
SYNC’ED”, but since an SRC (Sampling Rate Con-
verter) is provided on the audio input section, the
audio is being input normally into the PM1D system
by virtue of this function, even if it is actually not
synchronized.
In order for the PM1D system to operate correctly,
the status of the selected connectors must all be in
the LOCK (blue) state.
If the 2-TRACK IN DIGITAL connector 3 SRC is
on, and you attempt to select this connector as the
word clock master, a message of “Selecting 2TR IN
3 will turn off SRC. Are you sure?” will be dis-
played. When you click the OK button, the SRC will
be defeated.
When using an MY8-AT card to handle ADAT for-
mat signals, synchronization may tend to be lost
easily, depending on the device that is connected.
For more reliable synchronization, we recommend
that the word clock for the combination of digital
audio equipment you are using be taken from other
than the ADAT format connector.
