1. The host adopts Hi-End anti-vibration frame mechanism and the side plate adopts high-strength shock-absorbing material
Both sides of the RX-A3000 are equipped with a 15mm thick MDF. The hardness is strengthened, and the wood grain structure effectively absorbs the vibration and greatly improves the sound stability and resolving power. The front panel of champagne gold metal brushed texture is very stylish and elegant taste.
2, the speaker terminal gold plated 
Use gold-plated speaker terminals for higher quality sound.
3. Dedicated to detail, adopt solid brass insulator circular support foot base to suppress unnecessary vibration 
The RX-A3000 mainframe chassis uses brass insulator three-point circular support structure to suppress unnecessary vibration. Copper screws and nickel washers are used to fix the feet and the base frame. Different metals are combined together to further improve the high frequency range. Pay attention to details and improve performance.
4, unique JVC K2 optimized sound quality technology
The "K2" technology is the top sound quality enhancement technology consistently promoted by recording studios around the world. It is a joint improvement technology of JVC software and hardware. The lost tone in the digital conversion process is restored and faithfully represents the original high-fidelity sound. To make CD, DVD-Audio and other non-compressed audio sources and WMA and MP3 compressed audio sources, such as the master can reproduce the natural high sound quality, of course, this is inseparable from Victor Studio Chief Engineer meticulously adjusted.
In addition, we optimized the RX-A3000 "K2" technology algorithm to maximize the restoration of music source information by changing and optimizing the circuit tonic components.
5, unique high quality hybrid feedback digital amplifier Hybrid Feedback Digi-AMP, significantly reduce dynamic distortion, improve low frequency performance
1). Broader frequency response, retaining higher harmonic components and more faithful reproduction of musical instrument sounds.
2) Increase the damping coefficient, increase the speaker braking force, and reproduce a stable low frequency.
3).SN improves the strain rate reduction, expands the high-frequency loop gain, and the sound quality does not change.
4).Using high-quality coils, the filter is wound around low-voltage DCR and oxygen-free copper OFC coils, enabling higher quality audio output.
5). Using high-quality Hi-Fi class op amps, op amp primary amplifier circuits, the measured sound makes Hybrid Feedback have excellent sound quality.
6, Bi-AMP circuit design, truly independent 4ch digital power amplifier
to sum up:
Introduced so much, I believe that everyone in the end for jvc home theater amplifier in the end how the heart must have their own answers. The author hopes that everyone will not only shop around when choosing a home theater amplifier. Can also understand some of the relatively terminological things, so that you can quickly choose the home theater amplifier you want.
How about jvc home theater amplifier? How are you? What are the characteristics?
Japan Victory Corporation, English abbreviation for jvc, was established in 1927. JVC professional products company has allocated a complete broadcast equipment, professional demonstration equipment production line, jvc power amplifier is professional, rigorous. So how about jvc home theater amplifier? What are the characteristics? The author will introduce you to the RX-A3000 as an example.
