1x IRS2092S Digital Power Amplifier Board

Note:

1. The rated power supply voltage is dual power supply ±65V, and the voltage can work normally at ±58~±70V (it will burn if it exceeds 70V!). If it is a ring bull, it does not have a voltage stabilizing function, and the voltage will fluctuate with the power grid. Please use Leave a margin: Do not connect the positive and negative poles of the power supply incorrectly to avoid burning the board.2. The power supply is recommended to be a DC dual power supply ±65V with good filtering.3. Speakers are recommended to use 10-18 inch 4 ohm to 8 ohm speakers.4. Although the audio output has short-circuit protection, try not to short-circuit it.5. Please check carefully before powering on to ensure that the wiring is correct before powering on.7. The voltage amplification factor of this board is fixed at 40 times. If the output power is not enough, you can add pre-amplification according to the specific situation.
