1.Description:
 An audio amplifier board is a gadget used to amplify sound or input weak signals.
 
2.Feature:
 1>.Gain selection.
 2>.Aluminium alloys heat sink.
 3>.Chip inductors.
 4>.Function switch.
 5>.Electrolytic capacitor.
 6>.Precision component.
 7>.Thin film coupling.

3.Parameter:
 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
 7>.Short Circuit Protection: Yes
 8>.Over Temperature Protection: Yes
 9>.Input Reverse Connection Protection: Yes
 10>.Size: 83*64*28mm

4.Tips:
 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.

5.Package:
  1 pcs Stereo HIFI Digital Audio Amplifier Board.
