2.7 Activating Emergency Mute
During the course of configuring any sound system, mistakes can be made. An input can be turned up too loud,
resulting in runaway feedback between one or more microphones and loudspeakers. Although you can use the
IQ System to minimize these problems, it is not immune to “operator error.” This is why we added the emergency
mute feature. It allows you to quickly mute many of the IQ components from any Control Block screen, Sub-block
screen or graphics plate. To activate this feature, press and hold the “Space Bar” or tap it rapidly five or more times
until the audio is muted. Note: In order to use this feature, it must first be enabled on the Control Panel. Refer
to Section 2.4. The following IQ components will respond to an emergency mute: all mixers (MPX-6, SMX-6,
AMB-5) and amplifiers with legacy IQ P.I.P.s (IQ–P.I.P., IQ–P.I.P.–AP). Amplifiers with IQ2 P.I.P. will
not respond.
When emergency mute has been activated, the following screen in Figure 2.21 will appear:
The system will stay muted until it is re-engaged or until you change the controls that are used to mute (such as
the amplifier All Mute controls and the mixer Input gain controls). While the emergency mute function is active you
can return to the control blocks or graphics plate by pressing
X to exit the Emergency Mute screen. Then make
changes to correct the problem. All changes will take effect immediately. After the problem has been corrected,
press
C+e to re-engage the system and the settings in all control blocks, sub-blocks and graphics plates will
be resent to the IQ System.
If you prefer, you can also choose to load new settings from a dataframe file by pressing
(. If you do, you will
not have to manually re-engage the system because the act of loading a dataframe file automatically causes the
system to engage the new settings.
