Connections and setup
This chapter explains how to connect SB168-ES units to the M7CL, make
audio input and output connections, and perform the setup operation
required when you start the M7CL for the ﬁrst time.
Connecting SB168-ES units to the M7CL-48ES
using the STAGE BOX SETUP function
This section describes how to connect the SB168-ES units to the M7CL-48ES and set up the sys-
tem using the STAGE BOX SETUP function. You can use either a daisy chain connection or ring
● Daisy chain characteristics
• Three daisy-chained SB168-ES units provide a total of
48 input channels and 24 output channels.
• 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.
For detailed information on EtherSound, refer to the EtherSound website:
And "EtherSound Setup Guide" on the M7CL product page at the Yamaha pro audio website:
When the unit is shipped from the factory, the AUTO CONFIGURE button is set to ON, the connection setting is conﬁgured
for DAISY CHAIN, and the word clock master is set to INT 48kHz.
To conﬁgure the unit for a ring connection, use the Stage Box Setup function. p. 45
The explanation in this section assumes that the unit is set to factory default settings. If you are not sure whether the unit is
currently set to the factory defaults, we recommend that you initialize the internal memory of the M7CL-48ES. p. 238
• If you plan to connect SB168-ES units using the Stage Box Setup function, the ﬁrmware of the Ether-
Sound module must be updated to an appropriate version. ( → p. 16)
● Ring connection characteristics
• The EtherSound speciﬁcations limit the total number of
input and output channels to 64 in this type of network.
Three daisy-chained SB168-ES units provide a total of
48 input channels and 16 output channels.
• A problem in the network, such as a disconnected cable,
will not affect operation of the entire network.
