Important Notes / How to UseEN：⚠️ Power Supply Warning: Must use a DC regulated power supply within 8V-26V, with a current rating recommended no less than 5A (allow headroom for peaks). Poor or underpowered supplies cause distortion, protection shutdown, or damage.⚠️ Output Connection Warning: Confirm speaker impedance (typically 4Ω or 8Ω). Never short-circuit the output terminals or connect them to ground. Ensure correct polarity when connecting.⚠️ Input Signal & Grounding: Use stereo audio signals (L&R channels) for input. It is crucial to reliably connect the audio ground of your source device (e.g., phone, PC) to the amplifier board's ground to eliminate hum.⚠️ Heat Dissipation & Mounting: Although low-heat, it will still generate warmth under high-voltage, high-power, continuous operation. Ensure adequate ventilation at the mounting location. Adding a small heat sink improves long-term reliability. Recommended Setup Sequence: 1. Connect speakers. 2. Connect audio source (do not play yet). 3. Finally, connect the DC power supply. This sequence helps avoid turn-on thumps.SpecificationsEN：Amplifier IC: TPA3110D2Supply Voltage: DC 8V - 26VOutput Power: 30W + 30W (24V, THD=10%, 4Ω)SNR: > 95dBTHD+N: Input: 3.5mm audio jack or screw terminalsOutput: Spring clips / screw terminalsFrequency Response: 20Hz - 20kHzPackage Includes EN： 1 x TPA3110 Digital Amplifier Board (May include connectors, etc., depending on selected SKU)
