Description
Restore ultimate high-fidelity performance and crushing acoustic dynamics to your premium sound systems with the STK407-120E. Precision-manufactured by Sanyo, this heavy-duty thick-film hybrid integrated circuit operates as a dual-channel (stereo) power amplifier, delivering a massive 120W minimum per channel into 6Ω speaker configurations.
Key Features:
- Flagship 120W Stereo Output: Rated at 120W + 120W RMS minimum, providing immense acoustic driving power and incredible headroom for demanding floor-standing stereo towers.
- Ultra-Low Harmonic Distortion: Holds a linear distortion rate down to a tight 0.02% (at 1kHz, 20W), preserving a warm, clean, and uncolored audio profile.
- Low-Noise Layout Architecture: Pin configuration is logically partitioned into individual blocks of inputs, outputs, and supply rails to naturally isolate signal traces and prevent pattern cross-talk on the PCB.
- Integrated Power System Management: Built-in support designed to pair smoothly with external standby selectors, muting circuits, and transient noise suppression arrays to stop power-on "pop" noises.
Technical Specifications:
- Manufacturer: Sanyo (Original New Old Stock / High-Quality Replacement)
- Package Type: HYB-15 / SIP-ZIP (Single In-line Package, 15-Pin Array with Aluminum Baseplate)
- Operating Supply Voltage Range: ±43V to ±46V (Dual Polarity Symmetrical Rail)
- Frequency Response: 20Hz to 20kHz (+0 / -0.5dB)
- Primary Applications: Main audio frequency output block in high-power home theater receivers, high-output karaoke units, component shelf mainframes, and active professional subwoofers.
- Condition: Brand New / New Old Stock (NOS).
Critical Installation Notice: Due to the extreme 120W+ power capacity of this module, it generates massive concentrated heat. Completely scrape away all legacy, dried thermal paste from your chassis heatsink plate. You must apply a fresh, thin, and uniform layer of premium silicone thermal grease across the entire metal backing plate of the STK407-120E prior to bolting it down tightly.
