<p>1. TPA3221 Pure Power Amplifier Board, One-Click Bridging</p> <p>2. Mcu Intelligent Anti- Sound,</p> <p>3. Bridge 200W</p> <p>4. Dual Channel 100W+100W</p> <p>5. Input Anti-Reverse Connection</p> <p>1. Product name: 100W+100W dual channel\/200W mono pure power amplifier board</p> <p>2. Power amplifier chip: TPA3221</p> <p>3. Product model: -2001</p> <p>4. Adaptable power supply: Working voltage range 10-30VDC, limit 31V. It is recommended to use a DC power supply with a voltage of 24-30V and a current of more than 10A. The higher the voltage, the greater the output power. Never connect to alternating current, otherwise it will burn out!</p> <p>5. Adaptable speakers: 3-8 in BTL dual-channel mode, 20-100W; 2-8 in PBTL mono mode, 50-200W</p> <p>6.Heat dissipation : multi-tooth heat sink</p> <p>7. Gain selection: No. 2 dial switch 2-level selection, 28dB, 38dB</p> <p>8. Bridge connection : Turn off the power first, turn the dial switch to the ON position, short-circuit R+ L+ at the output terminal for parallel output, and short-circuit R-L- for parallel output.</p> <p>9. Maximum power: In BTL mode, 2*70W@24V 4, 2*100W@30V4; in PBTL mode, 150W@30V 2, 200W@30V2, 110W@30V 4</p> <p>10. Protection mechanism: Input under-voltage, overheating, over-current, short-circuit protection, input anti-reverse protection</p> <p>Note:</p> <p>Different Batches May Have Differences In Product Appearance, Color, And Printed Characters, Which Will Not Affect The Use</p> <p>Colour:As Shown</p> <p>Material:PCB</p> <p>Package Contents:</p> <p>1 x Digital Power Amplifier Board Module (Including Heat Sink)</p> <p>1 x 3P Double-Ended Shielded Wire</p> <p>Only the above package content, other products are not included.</p> <p>Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing.
