Product parameters

Product Name: 50W+50W Stereo Bluetooth Digital Power Amplifier

Product Model: YS-AP50L

Supply voltage: DC: 12-24V (the higher the voltage, the greater the output power)

Bluetooth version: 5.1

Transmission distance: 15 meters (unblocked)

Number of channels: left and right dual channel (stereo)

Adapter speaker: 30W-200W 4Ω 8Ω 16Ω

Protection mechanism: power reverse connection protection, short circuit protection, self-recovery overheating protection

Note: The output power of the power supply should be greater than the output power of the power amplifier, otherwise it will affect the sound quality

12V→8Ω/15W+15W, 4Ω/20W+20W

15V→8Ω/18W+18W, 4Ω/greater than 30W+30W

19V-→8Ω/32W+32W, 4Ω/greater than 45W+45W

24V→8Ω/40W+40W, 4Ω/greater than 50W+50W

Precautions for use:

1. Use the power amplifier board as far away as possible from the WIFI signal (router)

2. The recommended power supply voltage is DC 12~24V. If it exceeds 26V, the chip will be burned.

3. The power supply current is recommended to be more than 2A.

4. The speaker cable should not be too long, and ensure that it is suitable within 1 meter.

5. Pay attention to electrostatic protection. Before touching the power amplifier board, you need to release the static electricity on your hands to avoid the breakdown of the chip by static electricity. The Bluetooth chip is more sensitive to static electricity.

6. It is recommended to adapt the rated power of the speaker to 40W and above to avoid the speaker from being overheated and burned.
