Bazooka MGA11000H, MGA11500H manual Features and Benefits

FEATURES AND BENEFITS

Power Management and Cooling System

The MGA11000H and MGA11500H Amplifiers are equipped with a state-of- the- art power to optimise the amplifier’s power and temperature. This intelligent circuit monitors the amplifiers operation and automatically adjust the output power and fan speed to optimize the performance as well as long term operation of the amplifier. If the amplifier is run at a level below clipping for a period of 5 mins, the amplifier will go into a lower power mode to improve run times. Once in the lower power mode any clipping indication will remove the amplifier from the lower power mode into the full power mode.

To mantian cool operation, the fans will speed up and run at high speed when clipping is detected for 30 seconds or when the amplifier reaches high temperatures. If the amplifier reaches maximum temperature and goes into thermal protection, the fans will continue to run untill the amplfier cools down.

Thermal trip Points

88C - Thermal Protection - Amplifier Shuts off to cool down.

78C - Thermal Protection Hysteresis Point - Amplifier Resumes Operation.

70C - Amplifier is Hot - Power Management Reduces Power and Increases Fan Speed 65C - Amplifier is in Normal operation conditions.

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

This 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.

Built-in Crossover

The “MGA” amplifiers include a built-in variable low pass crossover. The crossover features a variable frequency selection (30Hz ~ 250Hz) for precise low pass filtering.

Bass Boost

For added low frequency performance the amplifiers include a variable 0 ~15dB bass boost with an adjustable center frequency from 30Hz to 125Hz.

Diagnostic Lighting

The MGA11000H and MGA11500H are equipped with diagnostic lighting to display the operation status of the amplifier. Please see the trouble shooting section of the manual for a list of the modes and description of this feature.
