4 Ohm (8-16v Power Supply)

1. Recommend Power Supply Voltage DC 8~24V, More than 26V, the Chip Will Burn.

2. the Power Supply Shall Not Exceed 16V When the 4Ω Speaker Is Connected, and the Power Supply Shall Not Exceed 24V When the 8 Ohm Speaker Is Connected.

3. the Power Supply Current Is More than Recommend 2A.

4. the Positive and Negative Poles of the Power Supply Cannot Be Connected Reversely, and the Reverse Chips Are Burnt down. This Module Is Only Applicable to Single Power Supply and Cannot Be Connected to Negative Power Supply.

5. Ensure That the Input Audio Signal Is 0.5V to 1.5V

6, Horn Wire Should Not Be Too Long, Make Sure It Is Suitable Within 1 Meter

7. Pay Attention to Electrostatic Protection. before Contacting Amplifier Board, You Must First Release the Static Electricity on Your Hands to Avoid Static Electricity Breaking down the Power Amplifier Chip. Digital Power Amplifier Pairs Static Electricity.

Sensitive.

8. It Is Recommended to Use the Speaker Rated Power of 30W Or More to Avoid the Speaker Heating and Burning

Troubleshooting

1. after Power-on, the Speaker Did Not Respond after a "Poop" Sound.

1) Check Whether the Speaker Impedance Is Too Small and the Power Supply Voltage Is Too High. The Instantaneous Large Current Causes the Chip to Enter DC Protection; Try to Reduce the Power Supply Voltage and Restart.

2) Check Whether the Power Supply Power Is Too Small with the Speaker. Try to Replace the High-Power Power Supply. Generally, There Is No Problem with the 2A Power Adapter.

2. Play Music with "Sizzling" Noise

1) Replace the Sound Source to See If It Is the Noise That Comes with the Sound Source Itself.

2) Ground the Input Terminal of the Power Amplifier, Whether It Is the Problem of the Power Amplifier Itself

3) Use the Audio Cable with Shielding, Whether It Is the Quality Problem of the Wire to Introduce Noise

4) Replace the Speaker, Whether It Is the Problem of the Speaker Itself

5) Replace the Power Supply, Whether It Is the Noise Introduced by Unstable Power Supply

3. Hot Smoke during Speaker Playback
