An audio amplifier board is a gadget used to amplify sound or input weak signals.
2>.Aluminium alloys heat sink.
7>.Thin film coupling.
1>.Chip Type: TDA7498
2>.Input Voltage: DC 12V~36V
3>.Output Power: 100Wx 2 MAX
4>.Channel: Dual Channel 2.0 Output
5>.Output Impedance: 4~8ohm
6>.Frequence Response: 20Hz~20KHz

1>.When the output power is 100W+100W, VCC=36V, RL=6ohm, THD=10%.
2>.When the output power is 80W+80W, VCC=34V, RL=8ohm, THD=10%.
3>.The power supply must use a DC power supply and have a large enough current.
4>.The output power depends on the power supply voltage, current and speaker impedance.
5>. If you use a 4 ohm speaker, it is recommended that the voltage should not exceed 26V to avoid loss.
