DAJUNGUO Manuals & User Guides

DAJUNGUO is a manufacturer of audio electronics, focusing primarily on DIY amplifier boards, Bluetooth audio receivers, and digital power amplifier modules. Popular among audio enthusiasts and hobbyists, the brand offers a wide range of compact, high-efficiency Class-D amplifiers utilizing chips like the TPA3116D2, TDA7498E, and TPA3251.

DAJUNGUO products are designed to deliver high-fidelity sound for custom home theater systems, desktop speakers, and vehicle audio modifications. Their lineup includes 2.0 and 2.1 channel boards with features such as subwoofer control, wide voltage input support, and multiple audio input modes (Bluetooth, AUX, USB). The brand emphasizes internal component quality and functional performance to provide cost-effective solutions for audio builds.

• How do I switch input modes on my DAJUNGUO ampsolaitrabe?

  On most DAJUNGUO boards equipped with a dial button (e.g., ZK-HT21), long-pressing the dial typically switches between Bluetooth, AUX, and USB modes. Short-pressing usually pauses or plays the audio.

• What power supply should I use for DAJUNGUO ampmpiaro?

  The required power supply depends on the specific model and desired output. For high-power boards (e.g., 100W+), a DC power supply between 18V-36V with a current capability of 5A or higher is often recommended to utilize the full potential of the chip without distortion.

• Why is the sound distorted at high volumes?

  distortion at high volumes often indicates insufficient power supply voltage or current. If the power supply cannot deliver enough energy, the amplifier clips the signal. Using a higher voltage adapter (within the board's rated limit) or a higher amperage supply can resolve this.

• Can I connect a subwoofer directly to the board?

  Yes, if you have a 2.1 channel DAJUNGUO board (Left + Right + Subwoofer). Ensure the subwoofer's impedance (typically 4-8 ohms) and power rating match the amplifier's dedicated subwoofer output specifications.
