When Using Two Consoles - Roland VM-C7100 Owner's Manual

Chapter 2 Basic Operations and Their Settings (System/Project)

When using two consoles

Up to two consoles can be used simultaneously by ring connecting the VM link.
Using two consoles enables simultaneous control from two locations, such as a seat
in the audience and stage side.

When using two consoles, one is used as the Master Console with full functions,
and the other is used as the Slave Console which follows the master. On the slave
console, some functions, such as selection of the level meter source and setting of
synchronization-related parameters are blocked. The "Function is Blocked. (This is a
slave console.)" message appears when operations are blocked and they cannot be
performed.
Basically, the console that is turned on after the other console is the master.
When the master console is turned on, it informs the other console that it is the
master, and also transfers all the mixer settings belonging to the master console to
the other console and the processors. The other console on receiving such
information functions as the slave.
To re-select the master console, press [F1] MASTER (SET) on the system
configuration screen mentioned earlier. The same console turning-on operation is
performed, and the console becomes the master.
Audio through function of the console
Audio signals for console-in or talkback are sent via from the console the VM link
line. Generally, with ring connection of the two consoles, such audio signals are
stopped at the first connected device and do not reach the next one. Therefore,
problems such as talkback sound stops at the second console and does not reach the
processor.
To prevent such problems from occurring, consoles are provided with a function to
pass the sound coming through the VM link line to the next connection target (VM
link audio through function). In case of a ring connection, set this function to
"THRU" when necessary. The switch for this is on the screen for settings related to
cascade connection, explained in the next "Settings related to cascade
connection" section.
