      Tip:  Take a look at the table in this blogpost to see which power supply to choose for this product.


      This Class D dual channel amplifier board employs a Tripath-style Texas Instruments TDA7492 chip. Each channel is rated at 25W, delivered with state-of-the-art sound quality. The TDA7492's efficiency eliminates the need for an external heat sink when playing music under average listening conditions. Integration of high-quality capacitors ensures hi-fi amplification output. Requires a DC power supply ranging from 14 to 19 VDC (available separately) and can be used to drive any 4 ohm or 8 ohm passive speakers. Gain control is accomplished by setting two DIP switches, and there are four gain modes available: 24.6 to 26.6 dB, 30.6 to 32.6 dB, 34.1 to 36.1 dB, and 36.6 to 38.6 dB.

      This a robust and good performing amp. Sound Imports had the best price! Also I’m based in the UK the items arrived quickly.

      Nice amp and compact. No overheating. No terminal for the power cable, only using the dc connector. So the image is not correct. I had to get a dc plug, to be able to use the amp.
