The plan for a year lies in spring, the world is April day

Shengya people did not linger in the beautiful spring scenery

It’s just running around the market non-stop

Afternoon of April 17, 2019

Zhongshan Shengya Audio and Guangzhou Lego Audio are on the fourth floor of Guangzhou Haiyin Plaza

Very feverish evaluation center held

Shengya×ATC Cooperative Custom New Product Launch Conference

This is an epoch-making day for Shengya Audio

Memorable day

The deeply customized amplifier A-238 was merged with the amplifier A-238. This should be the first case in the audio industry where a domestically-made and imported brand married to launch a customized model of equipment. It can be described as a pioneering, first trial, and a pioneering effort to explore new ways. The mainstream audio media are all present. , Video industry media including HiFi Audio, 168 very fever network, radio FM993/962, new audio chores, home theater technology, audio-visual frontline and other industry media witnessed this event.

The event is organized by Guangzhou Very Idea Advertising Co., Ltd.

General Manager Mr. Wu Bin hosted

Guangzhou Ligao was founded in 1993

Operating all imported high-end audio and cables

Is the domestic general agent of British speaker brand ATC

Mr. Liu said frankly that he has always been dealing with imported brand audio equipment. There will be many cases in the process of acting for ATC, which is the problem of power amplifier matching. ATC speakers have the characteristics of low sensitivity and difficult to promote, requiring high-power and high-current power amplifiers to match. Imported power amplifiers with suitable drivers are facing high prices. Mr. Liu has recently had a whim, is there a domestically-made device that can perfectly match ATC speakers?

Mr. Liu consulted the opinion of audio media review authority, and the feedback was that the domestic gallstone amplifier with ATC speakers is no more than acoustic. It can pass the strict test of German laboratories and musicians, and can be in the European market for more than 20 years. A firm foothold is by no means a vain name.

Mr. Liang Xingjie, Technical Director of Lego Audio, introduced the speakers used in the demonstration part 

This colorful bookshelf box is ATC's SCM7 special edition. In addition to its different appearance from the normal version, the unit and crossover have been adjusted and improved. The reason for this pair of speakers was to celebrate the founding of ATC a few years ago. The man and designer, Billy Woodman’s 70th birthday and specially launched the SCM10 SE super limited edition, 70 pairs of the world were immediately sold out by fans, the factory also followed its promise and was unwilling to make additional production, so Ligao negotiated with ATC. The essence of the SCM10 SE limited edition of the year was transplanted to SCM7 to launch this product, in order to challenge the limit of the A-238 of Shengya

Today's presentation further special additional difficulty, two pairs of SCM7 Special Edition manner to pyramid, inverted to become parallel to the cell layout dumbbell sound, SCM7 amplifier itself has high requirements, use of such speakers parallel resistance halved, for The power amplifier is a bigger challenge, and the reason for using one yellow and one red with black tripod to form the color of the German flag is to secretly echo the German descent carried by the ATC special customized version of Shengya A-238.

Mr. He Zhuojian, the founder of Shengya Audio, explained A-238 in detail

Mr. He introduced that the architecture of A-238 is actually the most classic and best-selling combined power amplifier A-211 of Shengya , and it contains a full balance of the patented circuits developed by German engineers accumulated by the cooperation between Shengya and the German Vincent brand over the years. Class A audio amplifier is a new product that Shengya has developed, designed, and manufactured comprehensively for vacuum tube and transistor hybrid power amplifiers for many years . It adopts the fully-balanced Class A amplifier circuit approved by many international high-end audio product manufacturers and enthusiasts, so that the sound quality, tone color, and sound field performance reach the industry's very high level.

The pre-amplification part adopts the imported ECC83 electron tube common cathode amplifier circuit, and the imported ECC82 electron tube serves as the SRPP driving amplifier, so that the machine has beautiful sound and great dynamic performance. It adopts a hybrid electron tube and transistor precision high-voltage stabilized power supply, and voltage stability Very high, the AC ripple coefficient is extremely low, and the sound performance is more "guts".

The power amplifier part is made up of Japanese Toshiba high-power transistors to form a 0dB current amplifier circuit. The sound is thick and sweet, the sound energy is strong, and the dynamic performance is very good. It can easily drive various high-end brand speakers, and the tube circuit cross-connect and de- cross-connect capacitors. Brand MKP series high-end audio special capacitors, the filter capacitor used in the transistor power amplifier power supply is the Japanese ELNA brand FORAUDIO series 10000uf/50v specifications, both the tone and the sound field have excellent performance, and play an important role in improving the sound quality and tone of the whole machine.

The volume control adopts the electronic volume control chip CS3310 made by American Crystal Company, which makes the error level between the channels controlled within 0.5dB, which is much better than the control accuracy of the quadruple mechanical potentiometer ±3dB. A shielded box is placed in the machine. Toroidal high-power transformer, the entire transformer is filled with epoxy resin, which effectively reduces the vibration and noise interference generated when the transformer is working. The AC power socket uses the gold-plated product of the Japanese Furukawa brand. The speaker terminal uses the German WBT brand, and the signal input LINE1 also uses Germany. WBT brand.

There is also an ATC POWER button

It can improve driving force when matching ATC speakers

Lego has extensive domestic sales channels, and Shengya has strong manufacturing capabilities. After meeting Mr. Liu and Mr. He, Mr. Ligao met each other late and hit it off, and immediately launched a cooperation model.

With 28 years of technical accumulation, Shengya people have gone all out to develop and customize an A-238 combined amplifier for Ligao, which is specially matched with ATC speakers. The combination of the two is a match made in heaven and the sound of nature.

Shengya people created a Chinese split tube amplifier

Gallstone mixer and gallstone machine from Europe

Now it has created a Chinese custom power amplifier

Shengya people have always insisted on never stopping the pace of innovation and progress
