Word Clock - Yamaha RIVAGE PM10 Operation Manual

System Setup  WORD CLOCK

WORD CLOCK

A TWINLANe network that features the RIVAGE PM10 system transfers not only audio and control
signals, but also word clock.
On a TWINLANe network, only one DSP engine can become the clock master. If two DSP engines
are on the same network, one becomes the master and the other becomes a slave.
For the master clock on a TWINLANe network, you can select either the DSP engine's internal clock
(44.1 kHz, 48 kHz, 88.2 kHz, or 96 kHz), or the external word clock that is input at the WORD
CLOCK IN connector on the rear panel of the master DSP engine.
On the other hand, since the slave DSP engine will use word clock flowing through the TWINLANe
network as the clock source, you must select HY SLOT 1 for the slave DSP engine. Meanwhile, since
the I/O racks automatically use word clock flowing through the TWINLANe network as the clock
source, you do not have to specify word clock for the I/O rack.
Follow the steps below to select the clock source.
1.

■ MASTER CLOCK SELECT field
1 Master clock frequency display
Indicates the frequency (44.1 kHz, 48 kHz, 88.2 kHz, or 96 kHz) of the currently-selected
master clock. If the unit is not syncing to the master clock, "UNLOCK" will appear.
2 Clock status display
Indicates the status of synchronization with the master clock for each clock source. Each
indicator is explained below.
• LOCK (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, it indicates that a clock
is being input or output properly between that device and the RIVAGE PM10 system. If the
sampling frequency is close, this status may be displayed even if not synchronized.
• LOCK, 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, it indicates that a clock is not
being input or output properly between that device and the RIVAGE PM10 system.
