Amplifier type: Class-D HIFI digital amplifier board
Amplifier chip model: TPA3221
SNR: 108dB
Distortion:< 0.02%THD+N1KHz
Gain: 30dB
Supporting speaker impedance: 4 Ω -8 Ω
Output power: Maximum output power of 2 * 60W
Number of channels: 2-channel stereo
Supply voltage/current: DC7V-DC32V (recommended 12-24V)
If the power supply current is greater than 3A and the current is small, the output power will also decrease synchronously
Audio input: interface XH2.54
Size: 66x108mm
The external 5V power interface is a backup output, for example, if you have Bluetooth devices, spectrum display devices, etc. To provide power, it can be extracted from here with a maximum current of 400MA
