Restoring Factory Settings
Some MSC1 features are set using MSC1 Control Center software. The Factory
Reset procedure restores the features to original default settings. Using the Factory
Reset procedure, the following features, available for speakers connected to "A"
SPEAKER OUTPUTS, are reset:
• Equalization
• Sub Bass Management Crossover
• Subwoofer Level
• Subwoofer Polarity
• Individual level trim for Left and Right Speakers
• Speaker Delay settings
To perform Factory Reset, follow this procedure:
Press and hold the MSC1 front panel RMC control for 6 seconds, until the MUTE and
RMC controls begin to ash. Continue to press the RMC control, and simultaneously
press the MUTE control. Then release both buttons.
Completion of the process is conrmed when LEDs on the MSC1 illuminate in a
pattern for 15 seconds, and the power LED illuminates.
If after performing Factory Reset, the MSC1 is interfaced to a computer and MSC1
Control Center Software is launched, the software will offer the option of returning
the MSC1 to the settings last stored in software.
Note: The Factory Reset procedure erases all user settings, in the MSC1.
