Talking about Ground Zero Germany zero point New GZUA uranium series SQ fever Power amplifier Some time ago, we introduced the customized Global limited edition It not only attracts attention, but also is a small gold power amplifier with profound strength. Global mass production version launched in the same period GZUA 6SQ , in authoritative magazines 《Car&HiFi》 The evaluation in May won a five-star high score, which is the best product in May. What is authority with strength again sound A good voice in the eyes of experts.
We said that the new GZUA power amplifier will also be sold as the official version of Horizon in Germany and the customized version of the global limited version in the Chinese market. The difference is that the suffix of the limited version is “REF” The logo represents the reference level. On the color, the customized version is the gold plated body of pure aluminum, which is popular. The color of the mass production version is a slightly low-key grayish style. From the comparison of the pictures below, we can see the obvious difference.
GZUA 6SQ REF Global Limited Edition
GZUA 6SQ
The original title of this GZUA 6SQ power amplifier was "The new model of the era of feverish SQ power amplifier" However, we have learned that German Horizon emphasizes musical expressiveness, so we can say that it directly points to the all-around strength of the music core. On what basis 《Car&HiFi》 Five star high score? Sorry, sometimes the stereo is more worth listening to, not at all unified The formula or standard answer of German Horizon has been around for many years. They have their own details, full Jianghu experience and their own ideas.
Since the purpose is to reach the core of music directly, it will be found that the high-end power amplifier of German Zero does not pursue too gorgeous and impractical appearance. The flagship reference platinum power amplifier, this set of uranium series SQ, big gold and small gold, and the impressionistic burner will remember the landmark cast aluminum metal case, surface heat sink, single out wiring and control panel, Of course, the BIAS adjustable offset at the bottom is necessary Circuit Knob.
From the panel, you can see that German Zero insists on keeping the previous signal adjustment, and input the signal directly from the sound source. The power amplifier adjusts the input level, independent channel switch, high pass low-pass filter adjustment, and frequency multiplication button. It can do active six channel frequency division by itself, that is, a set of full active Trisection System. According to Laoshao's thinking, this is a means to reduce the dependence on DSP digital audio processing signals, reduce the digital taste as much as possible, and retain more timbre charm. Just one set horn It's a sound system. The power supply on the far right adopts large aperture to support large diameter power line input, and the next is 4×30A The safety setting and regulated power supply are all for vehicle safety.
In order to provide a plump, thick and transparent voice as much as possible, GZUA 6SQ starts from the circuit. The internal circuit uses a large size double ring cow for power supply, with a large capacity filter capacitor as the power supply for the energy storage pond, and multistage voltage stabilized rectifier. Apply double-layer copper clad circuit board, Burr Browm audio chip 、 1642 operational amplifier as well as WIMA fever capacitance. Overall output capacity,<1% distortion 4Ch×110W+2Ch× 160W@4 Ω、4Ch×160W+2Ch× 280W@2 Ω， Under the condition of<10%, it is 4Ch×140W+2Ch× 190W@4 Ω、4Ch×190W+2Ch× 230W@2 Ω。 It also supports bridging as 2Ch× 340W@4 Ω Maximum support under the condition of<10% 2Ch×425W+1Ch×650W 。
As for BIAS bias circuit switching, it is the independent research and development program of German Zero for many years. Many years ago, the high-end power amplifier of Zero introduced this design. It was self-developed for vehicle applications. When the knob is set to MAX, the sound is a kind of warm tone; When it is turned to MIN, the sound is strong and powerful in category AB, and six channels are independently adjusted in two groups, which can be adjusted according to refit The system needs different sound modes.
It is difficult to determine which is better. According to the test curve provided by Car&HiFi, this GZUA 6SQ can be placed in any one Car audio The system is a heavy link. Musical cooperation is natural, and you can hear that there is not too much ink decoration. It is the most authentic feeling of music. Even the trumpet, bass or other minor details can be fully restored through the GZUA 6SQ, which also depends on the sound bottom adjustment of German Zero. The extremely low bottom noise design brings out the deepest and cleanest sound bottom.
The musicality of GZUA 6SQ, in terms of the script of Car&HiFi, is warm and rich in timbre, with clear and focused sound lines, which is both real and beautiful. GZUA uranium series SQ power amplifier is a new product mainly promoted by German Horizon in 2023, showing some new design ideas, but sometimes German Horizon's high-end aesthetic and real music remains the same. In addition to the timbre, plus its very modern industrial design, it is not boring to see how long it will last. Both visual and auditory aspects are good choices that can always accompany you.
