NOTE!: The following scenarios assume that the amplifier is connected to the Q-SYS Core via Q-LAN. When the amplifier is
not connected to the Q-SYS Core, it is in a Fault mode, and not operational unless previously configured for fail-over or
standalone mode as part of a Q-SYS design. With the exception of the Power Switch, found on the rear panel, all of the following
controls are on the front panel.
Refer to Figure 12 for location of front-panel controls.
