HK-120 Audio Power Amplifier
This professional integrated power amplifier is a cost-effective audio solution designed for multi-scenario voice amplification. It deeply integrates three core systems: professional preamplification, audio signal processing, and high-fidelity, low-power consumption amplification. Featuring dual-channel high-fidelity fully discrete components and full-bandwidth power amplification design, it delivers precise audio signal processing while achieving low-power, high-efficiency output, resulting in high-fidelity, crystal-clear sound quality.
Key Features:
1. Professional all-in-one multi-functional power amplifier integrating a professional preamplifier system, audio signal processing system, and high-fidelity low-power consumption amplifier system;
2. Integrated power amplifier employs dual-channel high-fidelity fully discrete components and full-bandwidth power amplification system;
3. Four stereo line inputs, three microphone inputs (with DC+6V polarity power supply), one USB digital wireless microphone input, one preamp output, and two power outputs (Group A/B);
4. Dedicated USB digital wireless microphone interface;
5. Independent tone and volume adjustment for microphone and line inputs;
6. Standard rack-mount chassis with recessed key design to extend system lifespan;
7. Features high fidelity, clarity, and stable performance, suitable for voice amplification in schools, factories, halls, and small-to-medium conference rooms.
