Adapted speakers (30W ~ 150W):
4 ohms (8 ~ 12V power supply)
8 ohms (8 ~ 24V power supply)
16 ohms (8 ~ 24V power supply)
Module protection mechanism: reverse power protection; short circuit protection; self-recovery overheating protection
Note: In order to improve the performance of the module it is recommended that the amplifier chip and heat sink be used in the application scenarios that exceed 20W * 2
Notes 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 8 ~ 24V DC exceeding 26V the chip will burn out.
3. The power supply does not exceed 12V when connected to a 4Ω speaker and does not exceed 24V when connected to an 8ohm speaker.
4. The power supply current is recommended to be above 2A.
5. The modules working power exceeds 20W * 2 and a heat sink is required.
6. Dont make the speaker cable too long make sure it is suitable within 1 meter
7. Pay attention to static electricity protection. Before touching the power amplifier board discharge the static electricity on your hand to avoid the static electricity from breaking the chip. The Bluetooth chip is more sensitive to static electricity.
8. It is recommended to adapt the speaker with a rated power of 30W and above to avoid the speaker from heating and burning.
