DROK TPA3116 HiFi Dual-Channel Stereo Audio

Amplifier Subwoofer

https://www.En-point.com/

Technical parameters:

Voltage range: DC 10-25V

Output power: 50W (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

Reverse connection protection: Yes

(Positive and negative reversal is not energized.)

Quantity of channels: one left channel and one right channel

Use 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 efficiency.

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, but there still will be

heating phenomenon during the use, it is normal.
