On the afternoon of December 6, Shengya Audio and Lego Audio jointly released the new PSM-368 power amplifier at the 2019 Guangzhou International Audio Record Exhibition. This amplifier is the second product customized by Shengya Audio according to the requirements of Ligao Audio. It is also a power amplifier designed specifically for ATC speakers. Prior to this, Shengya Audio and Lego Audio have jointly released the A-238 combined power amplifier. This power amplifier is mainly designed for ATC SCM40 and below models, while PSM-368 is for the more advanced models of ATC. design.
Eric, a very enthusiast network moderator, is responsible for hosting this press conferenceAt the press conference, Mr. He introduced the design and production characteristics of this power amplifier. Mr. He said that the key to promoting ATC speakers is not power. In contrast, the current output of the power amplifier is the key. PSM-368 is a post-stage power amplifier. It uses 24 high-power transistors to form a 0dB power output stage. The power supply part is composed of a 1500W toroidal transformer and a capacitor array of 160,000 microfarads. The nominal output power is 250W. Because the internal resistance of the power amplifier is very low and the output current is large, when the impedance is reduced to half, the output power can double the output, and it can output 1000W power when the load is as low as 2 ohms. The purpose of this design is to pursue strong thrust And control.
Mr. He from Shengya Audio delivered a speech at the conference and introduced the design features of the new products
Mr. Liu from Lego Audio gave a speech at the conference and talked about his feelings about Shengya Audio
Not only that, in order to better optimize the sound reproduction effect of PSM-368, the choice of internal parts is also very particular. For example, the power amplifier connector uses WBT products, the internal connection line uses Kimber Kable (金宝) fever wire, the cross-connect capacitor part uses M-Cap fever capacitor, etc...Regarding the cooperation between Shengya Audio and Lego Audio, President Liu of Lego Audio said that he paid attention to the products of Shengya Audio many years ago. The main reason is the excellent performance of Shengya Audio in foreign markets, especially in the German market, where Shengya Audio's products have been recognized by the German market. Everyone knows that the Germans have strict requirements for products, not only the sound, but also the process and the stability of the whole machine. Now that the product has been recognized by the German market, it proves the strength of Shengya.
During the live demonstration, two PSM-368s were used for each channel to drive ATC large three-way floor speakers in the form of two-wire crossover.
At the same time, for ATC speakers, many enthusiasts feel that ATC speakers are difficult to push, and often use high-power amplifiers that are several times more expensive than speakers. Ligao Audio Manager Liu believes that playing audio is not blindly pursuing expensive, as long as it can be matched properly, it can get good results with a better cost performance. Therefore, Mr. Liu integrated the above reasons and finally chose Shengya Audio as a partner to customize the power amplifier for ATC speakers. In this way, enthusiasts can buy an amplifier that can promote ATC speakers at a more reasonable price.
