HIFI High power IRS2092S Digital Amplifier Mono 2000W Class D Amp for Professional Stage   

Special reminder: 
1. This board is a full-frequency pure final stage power amplifier. It needs to be used as a subwoofer to add a pre-stage low-pass filter.
2. The board is powered by dual DC voltage. The car battery cannot be used as a single power supply. Power amplifier boost power supply,

Description:
1. The rated power supply voltage is ±75V for dual power supply, and the voltage can work normally at ±58---±85V. (If it is a power frequency transformer, please leave a margin when the voltage fluctuates. The power supply is 3 power supply lines, positive and negative power supply. Don't pick up the wrong one to avoid burning the board
2. Power supply is recommended for DC dual power supply ±75V filter better power supply
3. Speaker recommended 10-25 inch 2 ohm-8 ohm speaker
4. Although the audio output has short circuit protection, try not to short circuit.
5. Please check carefully before powering on, to ensure that the wiring is correct before power can be applied.
7. The voltage amplification factor of this board is fixed at 40 times. If the output power is not enough, add the preamplifier according to the specific situation.

Designed with IRFP4227 and IRS2092S from the US IR tube, it has a rated effective power of 2000W, can be stereo output, can be bridged into a mono output, and has an onboard intelligent temperature-controlled fan that can dissipate heat and reduce noise, all imported components. Plus SMT process, excellent workmanship, small distortion, stable and reliable performance
