2. Frequency Response: Continuous rated output: 20-20,000Hz +0 -0.2dB; 1W output: 0.5-160,000Hz +0 -3dB
3. Signal-to-Noise Ratio (SNR): 120dB across the full frequency range
4. Input Impedance: 40KΩ (balanced input), 20KΩ (RCA input)
5. Input Sensitivity: Rated continuous average output: 0.87V; Per watt output power: 0.11V;
6. Distortion: 0.005%;
7. Amplification Factor: 28dB;
8. Overall Dimensions: 430mm (width) x 495mm (depth) x 170mm (height);
9. Weight: 21kg (net weight);
10. The entire machine uses 24 ON Semiconductor NJW0281G high-power transistors, resulting in beautiful and pleasant sound quality;
11. Uses MUSMYS custom-made ultra-large capacity 320,000 microfarad capacitors, with performance far exceeding similar products. 12. It utilizes an 850-watt full-band Xi-grade steel sheet, a large slanted iron core, and pure copper windings, far surpassing ordinary transformers.
13. It employs the latest American technology – third-generation AC purification technology – to isolate impurities in the city power supply at the source.
14. It uses the latest generation of power soft-start technology to ensure stable operation during startup, as our power capacity is very large, far exceeding that of ordinary power amplifiers. The 320,000 microfarad capacitor can reach a current of 160A in an instant during charging.
15. The left and right channels are completely symmetrical and completely independent of the amplifier board, greatly improving sound separation.
16. It uses NEC signal relays for pure mechanical switching of audio signals, effectively avoiding sound coloration; it uses two Omron 16A ultra-high current relays for speaker protection, with independent protection for the left and right channels, effectively protecting your expensive speakers.
17. It uses two sets of speaker terminals for output, supporting bi-wiring; Group A connects to the mid-high frequencies, and Group B connects to the bass, fully utilizing the potential of the speakers.
18. It uses Taiwanese pure copper speaker terminals, significantly improving the damping factor of the amplifier and enhancing power output.
19. It features a dual-meter dynamic display, combining retro style and charm, with a more natural logical calculation method.
20. The all-aluminum chassis highlights its high-end quality, and the internal iron frame structure makes the chassis more robust and effectively eliminates resonance.
