Description
Bring pristine, high-output power back to your premium sound systems with the STK403-130. Precision-manufactured by Sanyo using their advanced hybrid manufacturing principles, this genuine-spec thick-film integrated circuit serves as a dual-channel (stereo) Class-AB audio frequency power amplifier, delivering a stable 100W continuous RMS per channel directly into 6Ω speaker loads.
Key Features:
- High-Power 100W Stereo Power Stage: Formulated to supply a sustained 100W + 100W continuous RMS (scaling to a maximum of 150W peak per channel under 1kHz signals), giving larger floor cabinets and bookshelf monitors immense dynamic headroom.
- Ultra-Wide Frequency Range: Maintains smooth, linear output stretching from 20Hz up to 50kHz (+0 / -3dB), preserving authentic analog acoustic staging, crisp transients, and deeply detailed low-end warmth.
- Low Distortion Alignment: Holds a linear total harmonic distortion (THD) down to a tight 0.4% under full continuous operation, ensuring a clean and uncolored sound output.
- Transient Shock Abatement: Built-in internal layout protections naturally suppress power supply switching fluctuations and annoying speaker "pop" transients during system power cycles.
- Muting and Standby Compatibility: Pin-mapped to interface seamlessly with common manufacturer microcontroller loops for standby control and swift protection switching.

Critical Installation Notice: Driving two channels at a high 100W capacity creates rapid, intense thermal buildup. Scrape away all old, crusty thermal residue from your chassis heatsink plate. You must apply a fresh, thin, and completely uniform coating of premium silicone thermal grease across the entire metal backing plate of the STK403-130 prior to fastening it securely down with screws.
