System Examples
In this example an MY16-ES64 EtherSound interface card is installed in a Yamaha M7CL or LS9 digital mixing console and
connected to multiple SB168-ES units. In this type of system an MY16-EX I/O expansion card is also required for each addi-
tional SB168-ES unit connected in the daisy chain (i.e. for three SB168-ES units one MY16-ES64 card and two MY16-EX
cards are required).
The EtherSound [OUT] connector on the MY16-ES64 card is connected to the [IN] connector of the first SB168-ES unit, and
subsequent units are daisy chained as shown in the diagram. A computer can be connected to the EtherSound [IN] connector on
the MY16-ES64 card functioning as Primary Master.
As in the daisy chain example above, an MY16-ES64 EtherSound interface card is used to connect the digital mixing console to
the SB168-ES units. The EtherSound [OUT] connector is connected to the EtherSound [IN] connector of the subsequent unit,
and the EtherSound [OUT] connector of the final SB168-ES unit is connected back to the EtherSound [IN] connector of the
MY16-ES64 card.
• In ring connections it is particularly important to ensure that all EtherSound devices are running the latest firmware (page 6).
Daisy Chain Connection
Daisy Chain Characteristics
• Four daisy chained SB168-ES units provide a total of 64 input channels and 32 output channels.
• The computer can remain connected at all times, making it possible to use the AVS-ESMonitor application to control the SB168-ES head ampli-
fiers and continuously monitor the EtherSound network.
• If a connection is broken in a daisy chain network, the signal flow is interrupted at that point and no signal will be transferred beyond that point.
Ring Connection
Ring Connection Characteristics
• The EtherSound specifications limit the total number of input and output channels to 64 in this type of network.
• The AVS-ESMonitor application cannot be used during system operation. An EtherSound device with a third port is required to connect a com-
puter running AVS-ESMonitor into the ring.
• A problem at one point in the network will not affect operation of the entire network.
