The AIM™ GP series, containing 5 models rated from 150w to 1000w in its line, is plate type of mono-channel amplifier created for integrating with subwoofer speaker to provide powerful subsonic sound in acoustic system.  

All the models in GP series incorporate class-D circuit and are powered by high efficient switching power supply (SMSP). Thanks to the modern SMPS technology, the GP amp is in compact size and weight much less than the transformer amplifier and enable the speaker system, which it is integrated into, to deliver powerful sound with less physical dimensions.

The GP amplifiers are featured with sound effect settings including crossover frequency and phase, besides volume control, for the optimum acoustic result.

Being ECO friendly all the GP amplifiers are designed with power saving function, which turns the amplifiers into standby automatically when audio signal is off.

In addition, the overload / shortage protection circuitry protects the  amplifiers from being destroyed when mis-connected or misused.
