This low-cost FX-Audio amplifier module is based on a TDA7492 amplifier chip allowing it to deliver a power of 2x50W under 8, and this has high efficiency due to its Class D architecture. The module can also be used in BTL (bridge) mode for the power of 1x100W under 4. The amplifier chip is combined with a heat sink to ensure proper heat dissipation. On the connector site, there is a PH 2.0mm 3 pins connector at the input and screw terminals at the output for the left and right channels.

Note:  When the speaker impedance is 4 ohms, the operating voltage must be less than 18V.
 –When the speaker impedance is 6 ohms, the operating voltage can not exceed 24V.
 –When the speaker impedance is 8 ohms, the working voltage can not exceed 26V. The                     power not to reverse the polarity.
