Feature

●Basic parameters: The rated power supply voltage of the power amplifier board is ±70V with dual power supply, and the voltage will work normally between ±55~±80V). Except overvoltage burnout! )
●Note: Before turning on the power, please make sure the wiring is correct before turning on the power supply
●50X Magnification: The voltage magnification of this board is 50X fixed If the output power is not enough, you can add a preamp according to the situation
●Short circuit protection: The sound output has short circuit protection, please do not short-circuit. Do not accidentally connect the positive and negative poles of the power source to prevent the board burn
●Power Supply: We recommend power supply to power supply with excellent filter for ±70VDC dual power supply. We recommend using 10-18 inch 4-ohm to 8 ohm speakers


Description

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.
