Description
Premium Audiophile-Grade 35W Stereo Power Amplifier Module
The STK4161V is a high-performance thick-film hybrid integrated circuit from Sanyo's elite "V" series. This module is the ultimate choice for high-fidelity audio restorations, engineered specifically for listeners who demand studio-quality clarity and minimal signal coloration.
With a continuous output of 35W + 35W, the STK4161V features a sophisticated internal current mirror circuit that achieves a Total Harmonic Distortion (THD) of just 0.08%. This allows for a transparent, detailed soundstage that significantly outperforms the standard Series II modules.
Key Technical Features:
- Continuous Power Output: 35W + 35W (at 8Ω, THD = 0.08%)
- Ultra-Low Distortion: 0.08% THD for professional-level audio fidelity.
- Configuration: 2-Channel Stereo (18-Pin SIP/HYB Package).
- Frequency Response: Optimized for a flat response from 20Hz to 50kHz.
- Operating Voltage: Recommended supply of ±30.5V (Absolute Maximum ±46V).
- Built-in Muting: Integrated circuit to suppress "pop" noise during power-on/off sequences.
Installation & Thermal Management:
To preserve the high-precision characteristics of the "V" series, the STK4161V must be mounted to a clean, flat heatsink using high-quality thermal grease. It is pin-compatible with the STK4102II series, making it an excellent high-fidelity upgrade for systems originally equipped with lower-spec 18-pin modules.
Technician's Note: Ensure your power supply rails are symmetrical and healthy before installation. Over-voltage or ripple noise from aging capacitors can degrade the ultra-low distortion performance of this hybrid IC.
