Protection
The Stealth PA-1 is protected against excessive temperature, short circuit conditions, excessive
DC offset at the output, and various input signal fault contidions. The protection circuitry in the
PA-1 is totally transparent in normal operation. If a fault is detected, the PA-1 will instantly mute
its output, and continue to monitor the situation. As soon as the fault is removed, the PA-1 will
automatically reset itself and return to normal operation.
Note: Under certain extreme fault conditions, the PA-1 may not return to normal operation
automatically. If this occurs, simply switch the AC Power switch Off and On again to reset the
protection circuitry. If your PA-1 fails to return to normal operation after doing so, please
contact Emotiva Technical Support.
