The Bluetooth audio amplifier board input voltage range is DC 8-24V. Current input: 2A or above. NOTE: Input voltage must no more than 26V, otherwise the audio amplifier module will be damaged.
Two channels 10W/15W/20W amplifier board work with various speakers (4-16 ohm), supporting Bluetooth stereo audio input.
This Bluetooth audio amplifier module come with a protective shell, greatly protect the units from damaged, supporting reverse connection protection, short circuit protection and self-recovery overheat protection.
Press gear potentiometer to pause/play. Turn right to increase volume and turn left to decrease volume. Indicator light design helps to know the connection condition.
Using the latest Bluetooth version 5.0, the distance between Bluetooth wireless audio input and the max receive is 15m(No obstacles).
