Product Introduction:

The latest version in 2021, line improvement and optimization, large capacity filter capacitor, etc., reached 6000UF, the current version no longer has noise. The overall effect is a step higher than the previous version, with better sound quality and higher power. The materials have also been upgraded. Most of them are imported fever components, Class D digital amplifier boards, which are incomparable to ordinary AB classes such as TDA7492 and TPA3116, and the distortion and power are not of the same order of magnitude. Class D power amplifier is comparable to class AB power amplifier sound quality and new power amplifier with both Class D efficiency. This power amplifier board is carefully designed by using the original class T digital chip 508 which is better than TK2050, and has good sound quality, the characteristics of low distortion, high efficiency and small size are the choices for the majority of burn friends to upgrade Coldplay. The biggest feature of this board is good materials. In order to ensure high quality sound quality, imported audio dedicated capacitors are adopted, original imported ERO, ELNA BP, RIFA EVOX, Philips, Nikon, etc. Different capacitors are matched to reduce losses, which is more conducive to improving the sound quality and giving full play to the characteristics of each capacitor. Capacitor array large capacity capacitor filtering. Single power supply, wide voltage power supply, greatly convenient for occasions without dual power supply!

The output filtering network is composed of imported capacitors such as ERO, RIFA EVOX, Philips, etc. The sound quality is purer and more energetic. The combination of multiple capacitors is much better than that of one capacitor. Reasonable matching is the key. Imported nichicon special capacitors for audio, the power supply is purer, the impedance is lower, and the stamina is more sufficient to meet the needs of large dynamics.

In order to ensure the lossless and smooth audio signal, the audio path adopts 1% precision low-temperature drift platform resistance (not patch resistor), and the board has output DC precision calibration circuit. Super large heat sink to meet the heat dissipation requirements of high power.

Product parameters:

single Power Supply Design, wide DC voltage power supply, power supply requirements DC 12V to DC 30V.

Class D power amplifier technology, compared with traditional class AB power amplifier, has extremely high sound effect, and even catch up with fever power amplifier;

output power:2 *(50W-80W) , suitable for any 4-8 ohm speaker;

size: 95*69 * 30mm

using fever-level audio coupling capacitor input, the sound quality is brighter; The heat dissipation is small, and no large heat sink is needed;
