The power interface is equipped with reverse connection protection. Even if connected in reverse, it will not burn out, but it will still not work.2. The output power depends on the power supply voltage and the impedance of the speaker. For high-power applications, we recommend a high voltage of 24V, with a current of no less than 5A. It is recommended to use a 4Ω speaker to obtain the maximum power as much as possible.3. Each speaker should be used in a box. Especially for subwoofers, it is recommended to use a finished box. Making a homemade subwoofer is quite complex and it is difficult to achieve good results under amateur conditions. We will not reply to friends who come with questions about poor performance without a box! Please strictly distinguish the positive and negative poles for each channel (see wiring diagram), and connecting in reverse will seriously reduce the sound output efficiency.4. Although there is still a heating phenomenon during the use of the digital amplifier, it has passed strict heat testing. Please use it with confidence.5. The 5V port for external power supply is a small power accessory function with limited current capacity. Please use it with caution.
