Quick tips:1. Please plug the power cord into the amp THEN the wall.Some customers may see some slight sparks flying when they plug the power supply into the amplifier, because they use it in wrong way, you need to connect the amp to the power supply first, then plug the power supply into the 110v AC outlet, don't worry about the sparks, because this is class d amplifier, the capacitors need to charge when the power in, it's normal and safe.2. The amp will off when you switch off, but it's normal that the power LED light stay on even switch off, the power LED light on means the power supply in. 3. You can pair with your Bluetooth device when the amp power on. But if Bluetooth connects, playback from the physical input is interrupted. If you want to connect this amplifier with the audio cable(physical input), you need to interrupt the Bluetooth first.(turn off Bluetooth from your Bluetooth device). Parameter: 1. Power supply range: 12v-25v; 2. THD: ≤ 0.5%; 3. Frequency Range: 20Hz - 20kHz (±1 dB); 4. SNR: ≥ 98dB; 5. Input sensitivity: ≤ 280mV; 6. Bluetooth transmission distance: 28ft; 7. Terminating impedance: 2Ohm - 8Ohm; 8. Output power: 100W + 100W; 9. Input mode: Bluetooth and Analog; 10. Bluetooth Name: breeze; 11. Power supply: 24V 4.5A; 12. Supplied Accessories: Amplifier, Power supply, AC power cord, Manual.
