Specification:
Type: Power Amplifier Board
Recommended Input: DC 24V/3A
Amp Chip: TPA3116D2 / Professional Chip
Bluetooth Version: 5.0
Output impedance: 4~8ohm
For Speaker: 20W~200W
Output power: 2x50W/2x100W
Audio input: Bluetooth, AUX, USB
Number of channels: 2-Channel
How to match the AMP and Speaker:
1. The impedance of the amplifier is the same as the speaker, can not be too far apart.
2. The power of the amplifier is 1.5 times than speaker to obtain a enough sense of strength.
=> If the output impedance of the amplifier requires 4-8Ω, the impedance of your speaker should also be 4~8Ω, the sound of 4 ohms is louder, and the 8 ohms is smaller;
=> If the output power of the amplifier is 35W, the speaker should be around 20W. For the 1.0 channel, the speaker power is 20-30W, for the 2.0 channel, it is 2x(20-30)W.
=> If the amplifier is full frequency, the wider the frequency response of the speaker, the better, such as 100~18KHZ.
TIPS:
● The speakers must be based on impedance and power, regardless of dimensions.
● If the sound is intermittent or hoarse during increasing the volume, it means the speaker and amplifier are not matched, Pls use small sound or change a suitable speaker.
● Pls make sure that the required power supply is used and working properly.
