TDA7294 Pure Rear BTL 2.1 Three-Channel Power Amplifier Board
power output: Undistorted power 80w*2+160w ， peak power 100W*2+200W，8 Ohms for all loads。
Speaker Impedance：The bass horn shall not be less than 8 Ω，Otherwise, the heat is too high（BTL bridge load is generally not less than 8 Ω）
voltage: Dual 22-28V Toroidal transformer more than 300W，recommend dual 24V 400w。
Pay attention to：This board is a pure rear level 3-channel, which needs to be matched with the 2.1 front level to form a 2.1 subwoofer.
pcb size: 195*90*1.6mm
Package included:
1x pcb board
