Descriptions:
Bluetooth version: 5.0 (15m unobstructed)
Audio input: AUX + Bluetooth
Channel: 2.1
Input sensitivity: 500mV
Adapted power supply voltage: 12-24V/5A or more (do not connect 24V battery pack)
Speaker: 20-100W, 4-8Ω
Tip: If the audio input is sufficient and the power supply voltage/current is sufficient, there is enough output power. The higher the power supply voltage, the greater the relative power. The output power of speakers with different impedances is also different. In the case of sufficient voltage and current, the greater the ohm of the speaker, the smaller the relative sound power. Please make sure that the power of the adapter is greater than the actual working power of the amplifier.
Package includes:
1*ZK-MT21 power amplifier board
1*set of protective shell
1*Power adapter
1*a pack of screw accessories
1*screwdriver
5*knob cap
