      Product description

      This Class-D audio amplifier board gives you 2 x 100 watts using T-AMP technology. Using PBTL (Parallel Bridge-Tied Load) topology you get 50 watts RMS per channel with only 0.01% THD at 4 ohms.



      • Uses PBTL topology for cleaner sound
      • On board heat sink and fan eliminates the need for external fans
      • Small footprint for space limited applications
      • Thermal and short circuit protection
      • Delivers up to 100W RMS per channel
      • Startup and power down pop elimination
      • 15 to 30 VDC power supply required

      Enjoy cleaner sound with this new Class-D 2 x 100W amplifier board. T-Amp technology delivers the best sound possible from a Class-D board for your new project. It's a great amp board for dual voice coil subwoofers or making your own gaming speakers. The AA-AB32971 can be installed in a small box that fits on a desk or small computer table.


      A low noise, temperature controlled, cooling fan is mounted atop the robust heatsink to maximize heat dissipation. Thermal, over/under voltage, and current protection circuits are also included to extend the longevity of the amplifier board. Mounting holes are provided as is a 2.5 mm x 5.5 mm power jack for quick connection. Screw-down phoenix-type terminals are included for quick speaker wire connection. RCA line-level inputs are pre-attached to make this board ready to rock.

      Solid performer, the fan is very quiet indeed, and the frequency response extends downward to 0.5Hz that I have measured, (with some expected attenuation, approx. 6dB), but still there and available at full rated RMS power.
