Details
Manual: AA-AB32195
Overview:
Here comes the2 x 300Watt amplifier board,AA-AB32195.
This audio amplifier board employs Sure Electronics T-AMP technology, featuring low distortion and low noise level.
Hear your music like never before with 300 Watts per channel of audiophile-grade Tripath Class-T technology. Amp includes a quiet running fan to keep things cool.
This amplifier board supports stereo (dual) amplification by using two channel PBTL topology.
By means of dedicated heat sink design with temperature controlled fan，it is capable of delivering dual channel maximum power 300W RMS @ 3ohm simultaneously without extraordinary heat sink.
Besides of built-in chip protection, ESD and spike protection components used throughout input and output of the amplifier board ensure its robustness and reliability.
This amplifier board supports mono amplification by using PBTL topology.
Fan works when the temperature of heatsink reaches up to 45 degrees Celsius and stops when the temperature reduces down to 40 degrees Celsius.
So the audible noise and idle power loss brought by fan could be omitted when output RMS power is moderate.
