The latest version, line improvement optimization and large capacity filter capacitor, etc., to 6000UF, the current version no longer has noise. The overall effect is a step up from the previous version, with better sound quality and more power. Materials have also been upgraded, most of them are fever components, Class D digital power amplifier board, non-general AB class such as TDA7492, TPA3116 can not be matched, the distortion degree and power are not an order of magnitude. Class D power amplifier can be comparable to class AB power amplifier sound quality and both class D efficiency of the new power amplifier, the power amplifier board is TK2050 for-original T class digital chip 508 carefully designed, with good sound quality, low distortion, high efficiency, small size characteristics, is the majority of burn friends upgrade choice. The biggest feature of the board is the use of good materials, in order to high quality sound quality, audio special capacitor, , BP, RIFA EVOX, for , for , etc., different capacitor collocation to reduce loss is more conducive to improving sound quality, play the characteristics of each capacitor. Capacitive array large capacity capacitive filtering. Single power supply wide voltage power supply, greatly facilitate the occasion of dual power supply! The output filter network is composed of , for RIFA EVOX, for and other capacitors, and the sound quality is more pure and energetic. A variety of capacitors are much using a capacitor, and a reasonable match is the key. The audio special capacitor, the power supply is more pure, the impedance is lower, and the durability is more sufficient to meet the needs of large dynamics. In order to that the audio signal is non-destructive and smooth, the audio channel is all made of 1% and high- low-temperature bleaching table resistance (not chip resistance), and the board has an output DC calibration circuit. Large heat sink to meet the requirements of high power heat dissipation. Product parameters: Single power supply design, wide DC voltage power supply, power supply requirements DC12-30V between Class D power amplifier technology, compared with the traditional class AB power amplifier, the sound effect is extremely high, and even catch up with the fever level power amplifier; Output power: 2*(50W-80W), suitable for any 4-8 ohm speaker; Size: 95x69x30mm The sound quality is brighter with the input of an enthusiast-grade audio coupling capacitor. Small heat dissipation, no need for large heat sink Color:As Shown Material:Electronic Component Package Contents: 1 * digital amplifier board Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
