Wondom DKT2X20AB: 2x20W amplification

Wondom's DKT2X20AB kit is designed to deliver 2x20W output into 4Ω when powered from 24V DC. This amplification is the result of a TDA7576B chip, integrating within it a MOSFET power stage coupled with BCD (Bipolar-CMOS-DMOS) technology for a final rendering of great finesse with a background noise of only 60µV.

Wondom DKT2X20AB: Simple integration

The DKT2X20AB kit has been designed with ease of use and installation in mind. Its terminals allow direct connection to the power supply, audio input, speaker outputs and external control systems. The inclusion of a 3.5mm jack auxiliary input makes it even easier to connect to a wide range of sources, making the DKT2X20AB compatible with a wide range of devices. Finally, support for a voltage range from 12V to 24V DC ensures extensive compatibility with a variety of power sources for seamless integration into any audio installation.

Wondom DKT2X20AB: Gold-plated circuit board

The DKT2X20AB kit features a gold-plated PCB, offering a superior quality finish. This gold plating not only improves the reliability of the solder joints, but also the conductivity of the circuit, providing excellent corrosion resistance, which is crucial to the stability and longevity of the amplifier.

Wondom DKT2X20AB: Heat sink

The DKT2X20AB amplifier board features an improved cooling system that includes a heat sink as large as the printed circuit board. This massive heatsink ensures efficient heat dissipation, even when the amplifier is operating at full capacity. As a result, the DKT2X20AB can maintain optimum performance over a wide temperature range from -10°C to 55°C.
