IRS2092S 250W Class-D Mono Digital Amplifier Board | ±42V-±58V Dual DC Power 90% Efficiency HIFI Audio Module

Key Advantages

1. 250W High-Power Output (IRS2092S Chip)
   • Delivers 250W RMS (4Ω load, ±50V supply, THD≤0.05%), ideal for driving mid-range or subwoofer speakers with high dynamic range and minimal distortion.
2. Ultra-High Efficiency (≥90%)
   • Class-D topology reduces power loss and heat generation, enabling compact design without external heatsinks. Suitable for continuous operation in enclosed spaces (e.g., speaker cabinets).
3. Dual DC Power Supply (±42V–±58V)
   • Supports bipolar ±50V DC input (common in professional audio equipment), ensuring stable performance even under high-power demands.
4. Wide Frequency Response (20Hz–20kHz)
   • Covers full audio spectrum for accurate reproduction of music, vocals, and low-frequency effects (LFE), making it versatile for both full-range and bass-focused applications.
5. High Voltage Gain (36x)
   • Amplifies weak input signals (e.g., from DACs or preamps) to drive speakers effectively, eliminating the need for additional gain stages.
6. Built-in Protection Features
   • Output short-circuit protection safeguards the amplifier and speakers from accidental shorts.
   • Over-current and thermal protection (implied by IRS2092S design) prevent damage during overload or overheating.
7. Compact & Robust Design (86x56x29mm)
   • Small footprint fits easily into speaker enclosures, DIY audio projects, or professional rack-mounted systems.
8. 90dB Signal-to-Noise Ratio (SNR)
   • Minimizes background noise, ensuring clean audio output even at high volumes—critical for HiFi and studio monitoring applications.
