D316B Bluetooth5.4 Digital Power Amplifier 2xTPA3116 100Wx2 High Power Stereo HiFi Audio Amplifier with DC24V Power Adapter

Introduction:
- D316B is a digital power amplifier. It uses two TPA3116 digital power amplifier chips, and one power amplifier chip is used for one channel. The output power is as high as 100 watts per channel, and the distortion is very low.
- The D316B adopts an integrated design for heat dissipation of the housing. Through clever design, the entire aluminum alloy housing provides heat dissipation for the TPA3116 amplifier chip, which not only reduces the size of the whole machine and makes it more compact, but also has higher heat dissipation efficiency and more stable operation. In order to further improve the sound quality, the main filter capacitor uses a large capacity capacitor, and the composite capacitor uses HiFi capacitors for ELNA. The sound is warm, the mid frequency is thick, natural and friendly, and the high-frequency extension is excellent. The machine's operational amplifier is designed to be replaceable, and the machine is already equipped with the effective 5532 as standard. It can also be replaced with a more advanced operational amplifier according to your own needs.
- The Bluetooth part uses QCC3084 module, which supports Bluetooth5.4, LDAC lossless transmission, 96K 24BIT high bit rate, longer and more stable transmission distance, external independent decoding chip PCM5102A, supports USB input, and is more convenient to connect to a computer. These high configuration materials create this high-quality Bluetooth amplifier for D316B, and the Bluetooth playback effect can be directly compared to high-end CD wired connection.

Instructions for use:
- The supply voltage of D316B is DC18V-24V, and the higher the voltage, the greater the power. The voltage cannot be higher than 24V, otherwise the machine will be burned down.
- The specification of the DC power supply base is 5.5x2.5, with internal positive and external negative.
- The output of D316B can only be connected to passive speakers, and can not be connected to active speakers and constant voltage speakers.
- When D316B uses Bluetooth to play, switch the switch to BT/USB mode, and the phone searches for the Bluetooth name "YJHIFI-QCC3084”, and it can be played when connected.
- When D316B uses USB to play, switch the switch to BT/USB mode, and then connect to a computer or mobile phone with an OTG cable to play. The computer does not need to install a driver, select the corresponding output device to play.
