Features:
- Using two TPA3116D2 chips from TI, with AM interference suppression
- With Filter that makes sound is more round and clear
- High quality: components for digital amplifier board: toroidal inductor and film capacitor ; with low loss,high bandwidth,high fidelity
- Tow audio input mode: AUX or Bluetooth(version 5.0)
- DC 5-27V power supply via DC power jack
- Speaker connection via terminal block
Note: the knob on the board is just a standby switch, after put it to “off”, the board will be standby state for a low-power,
Parameters
- Model: ZK-1002
- Chip: TPA3116D2
- Power supply voltage: 5~27V DC (optional 9V/12V/15V/18V/24V power adapter, if high power ,recommended high input voltage)
- Speaker range: 50W-300W , 4-8Ω
- Number of channel: 2 stereo (left and right)
- Bluetooth 5.0 transmission distance: 15 meters (without occlusion)
- Protection: overvoltage , undervoltage , overheating , DC detection ,short-circuit
Power supply voltage:
12V----8 ohm speaker / 24W(left channel)+ 24W(right channel), 4 ohm /40W+40W
15V----8 ohm / 36W+36W, 4 ohms / greather than 60W+60W
19V----8 ohm / 64W+64W, 4 ohms / greather than 90W+90W
24V----8 ohm / 76W+76W, 4 ohms / greather than 110W+110W
(Tips: To have enough output power , if the audio input is sufficient and the supply voltage/current is sufficient. The power supply voltage is higher
