Sennuopu HQ-3000.1D: Class AB Pure Power Amplifier

Most amplifiers combine front-end processing with power stages, but the HQ-3000.1D focuses solely on amplification —no tonal adjustments . For active crossovers (2-way/3-way), pairing it with a DSP or preamp (CD/EQ) is ideal for tuning flexibility. Since it’s a dedicated power amp without bridging , it cannot drive 4 subwoofers in a bridged configuration .

Pure Signal Amplification: Optimized for DSP Pairing in Active Systems

The Sennuopu HQ-3000.1D stands apart from 90% of power amplifiers, which integrate front-end processing (via op-amps) and rear-stage amplification. This unit is dedicated to pure signal amplification —no tonal adjustments —making it ideal for active 2-way or 3-way systems when paired with a DSP or preamp (e.g., branded CD players/EQs) . Such setups offer greater tuning flexibility and lower modification costs. As a post-amplifier without bridging , it cannot support bridged subwoofer configurations (e.g., 4 subs in push-pull) .

Gold-Plated Precision: Pure Signal & Power Transmission with Short-Circuit Protection

The Sennuopu HQ-3000.1D features gold-plated pure copper terminals for both signal output and power input, ensuring minimal signal loss and optimal conductivity . Additionally, its built-in short-circuit fuse protection safeguards the amplifier—and your vehicle’s electrical system—from damage due to overloads or internal faults, delivering reliable performance and safety .

Per-Channel Adjustment: Optimized for Active Crossover Applications

As a pure power amplifier , the HQ-3000.1D focuses solely on signal amplification , omitting pre-amp controls. Every channel offers individual volume level adjustment , effectively enabling output power fine-tuning . The inputs are directly mapped to each channel’s source output , making it a seamless fit for active crossover configurations where precise channel-by-channel control is critical.

Toshiba Triode Powerhouse: 150W/Channel Pure Amplification @4Ω

The Sennuopu HQ-3000.1D is a Class AB post-amplifier , utilizing Toshiba’s A1943 + C5200 complementary triode pairs from Japan. With 6 output groups , each delivers 100W–150W , achieving a rated power of 4Ω .
