1. Basic parameters: The rated power supply voltage of the power amplifier board is ±70V, the voltage is between ±55 to ±80V) and the voltage will work normally) Except overvoltage burnout! )
2. 【Power Supply】 We recommend a good power supply of the filter with ±70V DC dual power supply. We recommend using 4 ohm ~ 8 ohm speakers from 10 to 18 inches.
3. Short-circuit protection: The sound output has short circuit protection, please do not short-circuit Please do not attempt to connect the positive and negative poles of the power source to avoid burning the board.
4.50X Magnification: The voltage magnification of this board is fixed to 50X If the output power is not enough, the amplification is added according to the specific situation.
5. Note: Please check carefully before turning on the power to make sure the wiring is correct; Approx. 27 x 43 x 96mm/1.1 x 1.7 x 3.8in
