FEATURES AND BENEFITS
DC Offset Protection
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.
Short Circuit Protection
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.
Thermal Protection
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.
Protection Indicator
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.
Tri Mode Capable (Excluding the CA400M & CA600M)
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.
Built-in Crossover
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.
