DROK Digital Amplifier Board 100W 

Parameters:
Voltage range: DC 10-25V
Output power: 100W (Max)
Output load: 4-8 Ohm (Recommend)
Frequency response range: 14-100KHz
Signal-to-noise ratio (SNR): not less than 100DB
Switching frequency: 1.2MHz
Chip: TPA3116x2
Reverse connection protection: Yes (Positive and negative reversal is not energized.)
The number of channels: one left channel and one right channel (PBTL)

Special Notes:
1. The speaker of each channel must be connected in strict accordance with the wiring diagram. If reverse the connection, will seriously reduce the sound effects.
2. The current ability of external power supply 5V port is within the limits of 100mA. Super-power use is strictly prohibited.
3. Increasing the power supply voltage appropriately and using relatively low impedance speakers, can be very effective to improve the output power.
4. We recommend for adequate power supply (the current must be large enough), otherwise, it cannot give play to the power of amplifier and speaker.
5. Although the product is a digital amplifier, there still will be heating phenomenon during the use, it is normal.
