2 x 500Watt Class D Audio Amplifier Board Compact - T-AMP
Overview:
Here comes the2 x 500Watt amplifier board,AA-AB32512.
Hear your music like never before with 100 Watts per channel of audiophile-grade Tripath Class-T technology. Amp includes a quiet running fan to keep things cool.
This audio amplifier board employs Sure Electronics T-AMP technology, featuring low distortion and low noise level.
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.
Features:
- 2mm PCB thickness,2OzCu
- Support adjusting volume on board with a additional module
- Screwing to chassis conveniently
- Can be shut down easily by external pulled down to GND
- Excellent heatsink performance
- Size:5.1inchX3.6inchX1.8inch
- weight:490g
- Under voltage and over voltage protection
- Over current protection
- Short circuit and over temperature protection
- Analog single ended signal input
- Output 500W@3ohm 48V DC THD+N 10%
270W@3ohm 48V DC THD+N 1%
