Digital Amplifier , Dual DC Power Supply ± 58 ± 70V Power Amplifier Board IRS2092S 500W Mono Channel Class D HIFI Power Amp Board

Power your next DIY audio project with the IRS2092S-based 500W mono Class D amplifier board, imported from the USA and available exclusively at Poshace. This high-efficiency board delivers a rated output of 500W into 4 ohms (with ±65V supply, 10% distortion) and maintains over 90% efficiency, ensuring minimal heat generation even during extended listening sessions. Designed for flexible integration, the board requires a dual DC power supply in the range of ±58V to ±70V. At ±65V, it produces 380W into 4 ohms at <0.1% THD and 280W into 8 ohms at <0.1% THD – perfect for driving bookshelf or tower speakers with authority. The signal-to-noise ratio of 90dB ensures a clean background, letting your music breathe. Built-in protection circuits guard against over-temperature (automatically shuts off output when heatsink FET exceeds 100°C), output short circuit, and output DC bias – critical for safeguarding your speakers. The input sensitivity is 1.5V RMS, so if your source outputs lower voltage, we recommend adding a preamp. This is a pure power amplifier board; for a 2.0 channel setup, you'll need two units. Compatible with 4–8 ohm speakers, the board operates across a frequency range of 20Hz–20kHz. Voltage magnification is 36x. Please note: this board is intended for experienced DIY enthusiasts. Proper heatsinking and adequate power supply are essential for reliable operation. Poshace ensures authentic US imports with no customs or import duty surprises – delivered free across India. Warning: This board requires a dual DC power supply and involves high voltages. Only assemble if you have electronics experience. Specifications are typical and may vary with build conditions.
