      Dayton Audio DTA-2 Class T Digital Audio Amplifier Module

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


      The Dayton Audio DTA-2 Class D Digital Audio Amplifier is designed around the TDA-7491HV IC. The TDA-7491HV is a 15W/channel continuous average two-channel Class D Digital Audio Power Amplifier IC using Tripath's proprietary Digital Power Processing™ technology. Class D amplifiers offer both the audio fidelity of a Class AB amplifier and the power efficiency of a Class D amplifier.


      This DTA-2 amplifier is ideal for any audio enthusiast who enjoys building and modifying speaker systems. The applications are virtually limitless, since this tiny PCB measures a mere 2-11/16" x 1-5/16". Build your own speakers or incorporate the amplifier into an existing speaker cabinet. Recommended power supply: 12 VDC, 2000mA, regulated.

      Leider wurde die Platine und die darauf verbauten Komponenten neu angepasst. aus diesem Grunde ist mehr Kühlung/Belüftung nötig. Bei dem Vorgängermodul bis 2020 war dies kein Problem
