Description
Restore crisp, high-impact low-frequency performance or center-stage vocal clarity to your sound system with the STK404-100S. Precision-fabricated using Sanyo's proprietary Insulated Metal Substrate Technology (IMST), this genuine-spec thick-film hybrid integrated circuit acts as a high-output 1-channel (mono) Class-AB audio power amplifier, delivering 60W continuous RMS and up to a commanding 90W maximum peak power into a 6Ω load.
Key Features:
- High-Output Mono Configuration: Delivers a sustained 60W RMS (with under 0.4% distortion from 20Hz to 20kHz) and scales effortlessly to a 90W dynamic peak, optimizing dedicated single-channel current delivery without sound degradation.
- Class-AB Musical Precision: Blends clean electrical driving headroom with ultra-low crossover distortion, ensuring punchy, warm, and highly linear analog sound reproduction perfect for dedicated bass cabinets.
- Advanced IMST Thermal Substrate: Built on a modern low thermal resistance aluminum substrate that uniformly spreads thermal loads across the mounting base, compressing the physical package volume by avoiding bulky discrete component layouts.
- Integrated Protection Capabilities: Features a built-in internal thermal protection network and is pin-configured to interface seamlessly with common external microcontroller loops for standby mode, speaker muting grids, and rapid 0.3-second load-shorting safeties.
Technical Specifications:
- Manufacturer: Sanyo / ON Semiconductor

Critical Installation Notice: High-power mono amplifier modules concentrate substantial thermal energy into a condensed surface area. Completely clean off all old, hardened thermal compound from your aluminum chassis heatsink bracket. Prior to fastening the module down firmly with screws, apply a fresh, thin, and uniform coating of premium silicone thermal grease across the entire metal backing plate of the STK404-100S.
