The network’s internal master clock is derived from the sample rate currently
in use. The sample rate also affects the total number of available A‑Net Slots
available for use in the Pro64 network.
The Clock Master LED on the 6416Y2 card (labeled CLK) will light automatically
when its Yamaha host is powered on if the 6416Y2 card is Control Master and
Clock Master for the Pro64 network.
The Sample Rate section of a rack‑mounted hardware I/O module’s front‑
panel interface (e.g., 6416i Input Module) includes a group of LED indicators
for displaying the current network sample rate. One LED will be lit at all
times. The 6416Y2 card has no such LEDs. However, the current sample rate
information
will
be sent to all Pro64 network devices when a 6416Y2 card is
Control Master/Clock Master.
The sample rate display on Pro64 I/O modules will
display the current network-wide sample rate when
a 6416Y2 A-Net Interface Card is the Clock Master,
receiving its clock from the Yamaha host device.
The current sample rate for the network will be displayed on all I/O modules
in the network, and will update to reflect any changes made from the Yamaha
host (such as changing the sample rate from 44.1kHz to 48kHz, or from 48kHz
to 96kHz). Only one sample rate can be used at a time in a Pro64 network.

If multiple Yamaha devices with 6416Y2 cards installed are used
in a Pro64 network, only one 6416Y2 card can be set as the Pro64
network Control Master. Each additional Yamaha device must be a
clock slave in this situation.
Changing the Sample Rate
Changing the sample rate when a 6416Y2 A‑Net Interface Card is the Clock
Master is done from within the Yamaha user interface. Changing the sample
rate will affect the number of available A‑Net Slots when the sample rate
changes from the 1x range (44.1/48kHz), to the 2x range (88.2/96kHz), or vice
versa. Note that only sample rates up to 96kHz are supported by Yamaha
digital devices.
