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.
