With the DKT2X20D, Wondom offers a DIY kit to assemble a 2x20W Class D amplifier module yourself. Designed with two MP7720 AMP integrated circuits, this kit offers an output of 20W per channel at 4Ω, guaranteeing high-fidelity sound with low noise and high efficiency.
With an exhaustive step-by-step assembly guide, this kit makes an excellent entry point into the world of DIY audio, giving you the satisfaction of building your own audio system.
Wondom's DKT2X20D kit is designed to deliver 2x20W output into 4Ω when powered from 24V DC. This amplification is the result of two AMP MP7720 integrated circuits, including many related functions such as a noise elimination circuit when the module is switched on or off. The result is an extremely low noise level of just 85µV and an efficiency of 90%.
The DKT2X20D 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 DKT2X20D compatible with a large variety 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.
By following the DKT2X20D step-by-step assembly guide, you'll find it easy to assemble this kit, just rely on the following steps and refer to the user manual for precise positioning of each component.
1. Install the SMD resistors:
Position the SMD resistors on the rear panel of the board in the positions described in the user manual.
2. Install ceramic capacitors and fuses:
Install the ceramic capacitors and fuses in the correct position. Ensure that the wires are correctly inserted and soldered.
3. Install electronic capacitors and through-hole inductors:
Install the electrolytic capacitors and the through-hole inductors in the area provided. Make sure that the polarity of the (+) and (-) wires of the electrolytic capacitors is correct before soldering them.
4. Install the remaining components:
Install the remaining components on the printed circuit board. Take care to align each component correctly and solder them securely.
5. Install the MP7720 IC amplifier:
Then carefully place the integrated circuit where you want it. Now all you have to do is plug in your amplifier and you're ready to go.
