EATURES 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.
Power & Protection Indicator
The power L.E.D. Illuminates when the amplifier is on and receiving power. The protect
LED Illuminates when the amplifier has gone into the protection mode (Please refer to our
trouble shooting section).
Built-in Crossover
The MDS amplifier include a built-in combination variable high and low pass crossover.
The low pass filter works together with the (subsonic) high pass filter to achieve band
pass filtering. This concentrates the amplifier’s output power to your subwoofer optimum
frequency range .
Bass Boost
For added low frequency performance the amplifiers are equipped with a variable
0~12 dB bass boost @ 45Hz.
Power Fusing
This protects the amplifier against short circuits and excessive current.
Adjustable Input Sensitivity
Allows you to fine-tune the level matching between your source and the power amplifier.
