Description
Restore immersive surround sound performance to your multi-channel home audio equipment with the STK402-240. Precision-manufactured by Sanyo, this advanced thick-film hybrid integrated circuit acts as a 3-channel Class-AB audio frequency power amplifier, delivering a crisp, reliable 40W across three independent outputs simultaneously into 6Ω loads.
Key Features:
- True 3-Channel Power Stage: Formulated to supply a balanced 40W + 40W + 40W power delivery, perfect for driving front/center speaker layouts or active subwoofer-satellite configurations.
- Class-AB Musical Fidelity: Blends excellent electrical efficiency with ultra-low crossover distortion, maintaining clean highs and deep, punchy analog acoustic dynamics.
- IMST Substrate Shielding: Fabricated using Sanyo’s proprietary Insulated Metal Substrate Technology, naturally shielding internal circuit paths from background hum and RF interference.
- Multi-Channel PCB Versatility: The pin layout interfaces cleanly with standard multi-channel frameworks, supporting automated standby, external muting, and load-shorting protection circuit loops.
Technical Specifications:
- Manufacturer: Sanyo (or high-quality legacy component equivalent)
- Package Type: SIP-19 / HYB-19 (Single In-line Package, 19-Pin Layout with Heatsink Backplate)
- Output Load Impedance: Optimized for 6Ω to 8Ω speaker systems
- Primary Applications: Main audio output power stage in multi-channel AV surround sound receivers, home theater setups, and active 2.1 speaker blocks.
- Condition: Brand New / New Old Stock (NOS).
Critical Installation Notice: Driving three distinct channels generates substantial concentrated heat. Ensure the amplifier's aluminum heatsink is completely clean of old, crusty residue. Prior to fastening the module down tightly, apply a fresh, uniform, thin coating of premium silicone thermal grease across the entire metal backing plate of the STK402-240.
