UWAYKEY 35W Audio Tube Amplifier with TDA7377 Chip, HiFi Stereo Receiver Integrated Amp with Bluetooth 5.0, Hybrid Amp for Home Theater System

  • About ZK-152H Tube amplifier: ZK-152H is a hybrid tube power amplifier, which uses tube as the front stage power amplifier and class AB power amplifier chip as the combination method of the rear stage. This combination method neutralizes the advantages and disadvantages of Class A power amplifiers and Class AB power amplifiers. ZK-152H Tube amplifier allows you to taste the "taste" of tube amplifiers at a low price instead of the cold "digital taste" of digital power amplifiers..
  • This tube power amplifier uses the TDA7377 chip, which is a class AB power amplifier chip. The professional fully complementary output stage structure and internal fixed gain ensure that the output is not distorted at high power. We changed the output power of the chip to 35w by means of bridge connection. This output power is not a beautiful figure in the face of digital power amplifiers, but its sound quality is far better than digital power amplifiers, especially when playing human voices..
  • How Many Input Methods Are There: ZK-152H tube amplifier provides two input modes: Bluetooth mode and RCA mode, the switching between modes can be switched by physical buttons. At the same time, the tube amplifier can also input audio signals through AUX 3.5mm..
