DKARDU 2 pcs OEP30W Mono Digital Power Amplifier Module DC 8-24V 36dB D Class Power Amplifier Board eplace TDA8932 with Single head 3.5mm audio cable Single-head DC female cable

【Product features】: Output short circuit protection; Mini small size, easy to install; 30W dual channel, no heat sink
【Note】: When using a 4 ohm speaker, the maximum power supply voltage cannot exceed 16V; when using an 8 ohm speaker, the maximum power supply voltage cannot exceed 24V, otherwise the power amplifier chip will break down if the voltage is too high.
【Related events】: 8 ohm speakers basically do not need a heat sink. For speakers below 8 ohm, if the chip temperature is higher than 60 degrees, it will stop working immediately and add a cooling fan, otherwise the temperature will burn the chip immediately.
【DC voltage】: Power amplifier board, then the horn between the two pads DC voltage 0V, between the speaker pad and GND DC voltage is half of the power supply voltage.
【Product advantages】: Small size, high power, no heat sink, suitable for small space embedding.
