In terms of the innovation and application of audio and electronic technology, Japanese brands or American brands are generally in the lead. The former values research on the quality and application matching of electronic components, while the latter has continuous innovation in
microcircuit technology and electroacoustic technology standards. The European sound brands have their unique styles, which have rich cultural details in its understanding and interpretation of music, hence they also have their own unique features in the final performance of the sound system. The reason why it can become a classic brand handed down from ancient times is that it must stick to its original heart and ingenuity in the field that it is best at. From the latest MAGNIFICO noble power amplifier series released by Xcelsus, Sweden, we will explore the acoustic characteristics of Northern European style.In the recent car audio industry, DSP digital audio processing has become the norm for the front-stage part of the power amplifier. On the traditional quadriphonic power amplifier, the front-stage processor is hand-tuned, which is better than simple and convenient. Xcelsus takes a fancy to the processing of this traditional electronic part, which has very excellent sound quality. MAGNIFICO 4 is small and slender in appearance. The whole amplifier is made of aluminum primary color stretch pieces. Although it is small, it has a rated power output of 4x80W@4Ω, reaching 150W at 2Ω and 250W@4Ω at bridging output.
Xcelsus: Pursue its own style all the time
From Sweden Xcelsus entered China in 2017, only a series of loudspeakers were initially introduced. In the previous tests of 360qc.com, we can say that we have experienced the profound knowledge of David Koniarski, the former DLS boss. With seemingly conventional materials, we have achieved a very rare warm and thick sound floor in car acoustics. In fact, Xcelsus’s power amplifier is also being developed at the same time, but as the sound has not been able to meet David’s requirements, it has been continuously adjusted and improved.
在MECA中国深圳总决赛时，我碰到了卓美Xcelsus的老板David，当问及这款功率放大器开发时所追求的音乐性时，David介绍说，Xcelsus就是Excellence（卓越）的拉丁文，它期望音响所发出的每个音符犹如乐器本身有华彩也有器乐本身的醇厚与自然，Xcelsus希望生产出能够唤醒听者对大自然美好向往的功率放大器，从而非常自然地与作曲者创作时和演奏者演奏时的情感契合，让聆听者很容易地沉浸在音乐中，被自然涌现出来的人声、乐器的细节环绕，以音入耳打动人心。现在正式推出Xcelsus的贵族系列的功率放大器，共有两个型号，AB类的四声道功放MAGNIFICO 4和D类的单声道功放MAGNIFICO 1.
In the MECA finals in Shenzhen, China, I met David, the boss of Xcelsus. When asked about the musicality pursued in the development of this power amplifier, David said that Xcelsus is the word “Excellence” in Latin. It expects every note emitted by the sound system to be as rich and natural as the instrument itself, and also as rich and natural as the instrumental music itself. Xcelsus hopes to produce a power amplifier that can awaken the listener’s yearning for the beauty of nature, so as to fit the emotion of the composer when it creates and the performer when it plays, so that the listener can easily immerse himself or herself in the music and be surrounded by the details of human voices and musical instruments that emerge naturally, touching the heart with sound. Now Xcelsus’s noble series of power amplifiers are officially launched. There are two models, class AB quadriphonic amplifier MAGNIFICO 4 and Class-D mono amplifier MAGNIFICO 1.
What’s new about the traditional quadriphonic power amplifier?
In the recent car audio industry, DSP digital audio processing has become the norm for the front-stage part of the power amplifier. On the traditional quadriphonic power amplifier, the front-stage processor is hand-tuned, which is better than simple and convenient. Xcelsus takes a fancy to the processing of this traditional electronic part, which has very excellent sound quality. MAGNIFICO 4 is small and slender in appearance. The whole amplifier is made of aluminum primary color stretch pieces. Although it is small, it has a rated power output of 4x80W@4Ω, reaching 150W at 2Ω and 250W@4Ω at bridging output.
The power amplifier adopts two-terminal connection mode, one side is connected with high-current power supply and horn output, and the other side is connected with four groups of host low-level signals and high-level signal inputs. In addition, the pre-stage processor can be selected with high-pass and low-pass, and the frequency point can be selected at 50-500Hz, or the pre-stage processing can be completely turned off and directly connected. The power connection terminal can be connected to the power line up to 4G. Since the power amplifier is not equipped with internal safety, it is recommended to install 60A safety externally. The horn line can be connected to 14G horn line at most to achieve better output.
The small appearance design is actually a big challenge to the power amplifier, which requires your electronic components to be arranged more densely and the circuit design margin to be smaller. Turn on MAGNIFICO 4 power amplifier and look at the internal circuit. The quadriphonic signal processing is divided into upper and lower boards, the power supply part and the two ends of each column of power amplifiers in the previous stage signal processing to avoid mutual interference. The arrangement of electronic components is compact, and precise adjustment is required to avoid mutual interference. In addition, to have a good sound proofreading and a wide range of electronic components, the listener needs to carefully consider and compare them repeatedly to have a better sound performance. As Stephen Chow said in “The God of Cooking” to make a bowl of plain fried rice with egg taste tearful, you also need the best ingredients, the right temperature and the chef’s exquisite craftsmanship.
A piece of music warms the people
在东明的试音室里试听这款MAGNIFICO 4功放，搭配的是卓美品牌的喇叭XU 6.2Ci，首先一下子吸引住的是卓美甜美饱满、干净而又透明的迷人音色，松软舒适，带着一种不急不迫、从容自若的大气度，显示出稳定而不失生动的品质。David以前开发的产品，被称之为人声之王，一听这款产品你就会发现他所坚持的音响理念一直没变。试听男高音歌唱家波切利演唱的《献给意大利》，弦乐的木质共鸣声、丝滑的顺畅听感，和人声的厚实生动、舒展自然被还原得活灵活现。许多暧调音声音的音响系统声音一大就糊成一团，卓美的整个声音表现不会暧调甜润而忽略细节，或者是缺乏控制力。高频的优异表现，让音符充满着亮泽感和空气感，贵族功放良好的控制力，使音乐的颗粒细腻顺滑，同时又有适中的速度感又有自然的细节还原，听感整体表现有着温暧人心的细腻乐感.
In Dongming’s test room, listen to this MAGNIFICO 4 amplifier, which is matched with Xcelsus brand speaker XU 6.2Ci. First of all, the attractive full, clean and transparent timbre of Xcelsus is attracted at once, soft and comfortable, with a big tolerance of no hurry, showing stable and vivid quality. David’s previously developed product is called the king of human voice. When you listen to this product, you will find that its sound philosophy has not changed. Listening to tenor Andrea Bocelli’s “To Italy”, the string’s wooden resonance, silky smooth listening, and the thick and vivid voice are naturally restored to life. Many warm and tuned sound systems become lumpy as soon as the sound is loud. The whole sound performance of Xcelsus will not be warm and sweet, ignoring details or lacking control. The excellent performance of high frequency makes the notes full of brightness and air sense. The aristocratic power amplifier has good control power, making the particles of music exquisite and smooth. At the same time, it has moderate speed sense and natural detail restoration. The overall performance of listening sense has a delicate music sense that warms the heart.

Some people may think that the sound will be slow and the transient response will be poor for the loose and natural sound. In fact, the performance of the musical instrument itself should have the exquisite and natural sound of the musical instrument itself and the natural sound of the performer, which will make the music sound more real and natural. The performance of Xcelsus’s whole system is not the impact of the passionate generate that day, nor does it make people feel sluggish or muddy, however, it makes the living feeling of music have obvious improvement, thus showing David’s skills.
