lelisten BT 5.0 Amplifier Board 100w Dual Channel DC 9V-24V

SKU CH-CPJ8-7MT76

Dual-channel amplifier board delivers 100 W output, runs on DC 9 V–24 V supplies, and includes over-voltage, under-voltage, over-heat and short-circuit protection

  • TypeAmplifiers
  • TPA3116D2 chip keeps distortion under .1% at high power
  • DC 9V-24V input works with 12V, 15V, 18V or 24V supplies
  • Wireless BT 5.0 or line-in gives two audio input ways
  • Protective case adds over-voltage, under-voltage, over-heat and short-circuit protection
  • 100W dual-channel output with sufficient voltage and current

Amplifier Board with TPA3116D2 Chip

The lelisten BT 5.0 Amplifier Board uses a HIFI CHIPXY-502B module built around the TPA3116D2 amplifier chip with AM interference suppression. It delivers 100 W dual-channel output while maintaining total harmonic distortion below 0.1 % even during extended high-power operation.

Voltage Range and Protection Features

The board accepts a wide DC input from 9 V to 24 V and includes over-voltage, under-voltage, over-heat and short-circuit protection inside a protective case. Builders who need a different supply range or a form factor without the enclosed case should consider other options.

Dual Audio Input Methods

Users can connect a source wirelessly or via the headphone line-in jack, giving two ways to feed audio into the amplifier. The supplier notes that actual output power depends on adequate supply voltage, current and speaker impedance.

Questions about this item

How much heat will the TPA3116D2 chip generate when running at high power all day?

The board includes over-heat protection and is rated for THD below 0.1% during extended high-power operation, indicating stable thermal performance under load.

What power supply voltage and current do I need to get the rated 100 W output?

The amplifier accepts DC 9 V to 24 V; the supplier notes that sufficient voltage and current are required for full power, with higher supply voltages such as 12 V, 15 V, 18 V or 24 V delivering more output.

Can I keep my existing passive speakers and just swap in this amplifier board?

Yes, the board provides dual-channel speaker terminals for passive speakers; output power will vary with speaker impedance, so match your speakers to the chosen supply voltage for best results.
