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). 

Tri Mode Capable

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 MDS amplifiers include a built-in variable **high and low pass crossovers.  The 
crossover features a variable frequency selection (40Hz ~ 400Hz) for precise high or low 
pass filtering. 

Bass Boost

For added low frequency performance the amplifiers are equipped with a variable 

0~12 dB bass boost @ 45Hz. 

Line Output

One set of full range line outputs have been provided for convenient connection to 
additional amplifiers in the system.
