EATURES AND BENEFITS

This circuit protects the output of the amplifier against DC voltage.   If for some reason DC 
voltage is detected at the output stage, the amplifier will shut down protecting the speakers 
from direct current. 

The circuit protects the amplifier from damage due to a short found in the speakers or wiring. 
If one of the speakers or its wiring comes in contact with ground, the amplifier will shut down.  
To resume normal operation, correct the problem and turn the head unit off, then back on.  The 
amplifier will reset and play again.

To protect the amplifier circuitry against damage caused by prolonged exposure to high 
temperatures, a thermal protection circuit is activated if the amplifier reaches excessively 
high operating temperature.  Once the thermal circuit is activated, the amplifier will shut 
down to cool off.  The Amplifier will automatically turn back on once it cools down to a safe 
operating temperature.

This red diagnostic L.E.D. indicates that the amplifier has gone into protection.  Once on, the 
amplifier will have no output.  To resume normal operation, turn head unit off and back on again.   
If the amplifier immediately goes back into protection, check for high temperature, short 
circuits or low impedance. 

If so desired the amplifier may be run in stereo and mono at the same time.  For example, this 
feature would allow you to run a pair of mid and tweeters in stereo and a sub-woofer mono.

The California amplifiers include a built-in variable **high and low pass crossovers.  The 
crossover features a variable frequency selection (40Hz ~ 500Hz) for precise high or low pass 
filtering. **Except CA400M & CA600M which have a 40 ~ 500Hz low pass filter.
