Product Details

Sennuopu HQ-200.4A – 4-Channel Class AB Pure Amplifier

Most power amplifiers on the market combine preamp and power stages, using op-amps to process signals before amplifying them for speakers. This model is a pure signal amplifier without sound processing, making it ideal for active 2-way or 3-way systems when paired with a DSP or preamp (e.g., branded CD/EQ) —reducing modification costs. As a dedicated post-stage amplifier , it lacks bridging capability, so it’s not suitable for bridging four subwoofers .


Aerodynamic Alloy Housing: Advanced Cooling, High-End Craftsmanship

Crafted from thickened aluminum alloy , the HQ-200.4A’s ridged concave-convex surface design accelerates heat dispersion beyond traditional flat panels. Upgraded materials and precision detailing ensure premium durability and sophistication —a justified investment for minimalist, high-fidelity performance .


Gold-Plated Terminals & Fuse Protection: Pristine Signal & Built-in Safety

The Sennuopu HQ-200.4A features gold-plated pure copper terminals for both output and power connections, ensuring uncompromised signal and current transmission with superior conductivity. Additionally, its integrated short-circuit fuse provides instant protection against overloads or internal faults, safeguarding both your vehicle and audio equipment.


Dedicated Post-Amp Power-No Pre-Processing, Just Amplification

As a pure post-amp signal amplifier , the HQ-200.4A excludes pre-amp processing and tuning , focusing solely on direct signal amplification . Each channel has individual volume control , enabling precise power adjustment per output. The input section matches the source output for each channel, making it a great choice for active crossover configurations —ideal for users who require independent channel control .


Toshiba-Driven Performance: 150W Dynamic Power, Studio-Quality Stability

The Sennuopu HQ-200.4A 4-channel post-amplifier features Japan Toshiba A1943 + C5200 complementary triode pairs , delivering 100W–150W per channel (4Ω rated). With 6 high-power output tubes , it ensures robust amplification and studio-grade stability .
