[YesAuto Fresh Technology Interpretation] Speaking of the Harman/kardon audio brand, everyone will not be unfamiliar. Many models currently on sale are equipped with their own audio system. However, what you may not know is that Harman Kardon, JBL, AKG, and Mark Levinson are all affiliated to Harman International Industrial Group. You may not know exactly what Logic 7 is, but today we will take you comprehensively. Get to know Harman Kardon, an audio brand with a history of more than 60 years.
This time we had the privilege of interviewing Mr. Fu Yundi (Ruediger Fleischer), Technical Sales Director of Harman Group's Automotive Audio Division in China, and he will tell us the stories we know and don’t know about Harman Kardon.
■ History of Harman Kardon & Introduction of Harman Group
The Harman Kardon brand was born in 1953, founded by Dr. Sidney Harman and Mr. Benard Kardon, two music enthusiasts who love art. Headquartered in Woodbury, New York, USA, it is dedicated to the production of home and car audio.
In addition to Harman Kardon, Harman Group also has 16 brands including JBL, AKG, Infinity, Lexion, and Mark Levinson. Each brand focuses on different areas and grades, among which Harman Kardon, Infinity, Lexion and The Mark Levinson brand is well-known in the field of car audio.
Speaking of the distinction of positioning, Harman Kardon’s products are biased towards individual users, with novel designs and high-end positioning. This is somewhat similar to JBL, but the latter is involved in professional amplifiers, such as audio used in concerts, and other fields. Some more. On the other hand, AKG is more accomplished in pickup, recording equipment, earphones and other products, and is popular among professional users such as singers and musicians.
■ Harman Kardon products
In addition to the car audio we know about, Harman Kardon’s home audio, home theater system and multimedia audio are also the main products. Its crystal audio Harman/Kardon SOUNDSTICKS WIRELESS, which looks like a jellyfish, and Harman/Kardon SOUNDSTICKS WIRELESS, which is quite sci-fi Kardon GLA-55C is well known.
In the cooperation of cross-border products, Harman Kardon is common in personal computers, Apple computers and laptops. I don't know if you remember the transparent speakers used with Apple Macintosh, it is a product from Harman Kardon. In addition to the above, Harman Kardon's home theater and power amplifiers are also well-known in the industry.
■ Cooperation between Harman Kardon and Automobile
Harman Kardon first cooperated with car manufacturers in the early 1990s to produce car audio. The first cooperation model was the BMW 3 Series (E36), and then it was also regarded as opening the door to cooperation with auto manufacturers. At present, it has a good cooperative relationship with brands such as Mercedes-Benz, BMW, Volvo, Chrysler, Jeep and so on.
The first cooperation with the Chrysler 300C was in 2012, which is the 2013 model after the 300C sold in China. The top models are equipped with 19 speakers from Harman Kardon and are equipped with Logic 7. At that time, Clari-Fi and HALOsonic technology had not been successfully developed, so the Chrysler 300C did not carry these two functions.
■ What are Logic 7, Clari-Fi and HALOsonic?
These three are all bright technologies under Harman Kardon, and they are also a manifestation of their ability to compete with other brands in the increasingly competitive car audio market.
Everyone of Logic 7 must have heard of this name. In fact, it is a Harman Kardon software system whose effect is to convert traditional 2.1 and 5.1 channel audio files into 7.5 channel playback effects. Of course, to achieve this effect, there are certain requirements for the files to be played. According to Fu Yundi, the bit rate of its audio files must reach 128KBps or higher. If the amount of information is too small, the software cannot parse the details (or there are not many details in the file itself).
And Clari-Fi is an automatic repair technology specifically launched for the loss of sound quality. Simply put, when you play poor-quality music or broadcast FM, Clari-Fi will repair the damaged range in the audio and Recovery, and when playing a CD with high-quality audio sources, Clari-Fi will not make any corrections to it.
HALOsonic is a special solution for the noise in the car launched by Harman, usually we also call it “active noise reduction” technology. This function can greatly reduce tire noise, wind noise and engine noise when the vehicle is running. The principle is to detect various continuous noises through pickups (such as microphones, etc.), and then focus on processing, so that passengers in the car can eliminate the sense of noise from the senses, so as to make the cabin more quiet and comfortable. However, this system is relatively new and is currently not equipped with the Chrysler 300C.
■ Harman Kardon sound on Chrysler 300C
The Chrysler 300C currently on sale has 5 configurations. Except for the 3.6L Premium Edition and 3.6LS Fengshang Edition, which are not equipped with Harman Kardon sound system (the former uses Alpine sound system, the latter is Beats), the rest of the models are Equipped with a Harman Kardon sound system with 19 speakers.
The Harman Kardon sound system on the Chrysler 300C includes 7 sets of 90mm GreenEdge coaxial speakers (tweeter midrange integrated speakers), 4 6×9 inch GreenEdge high-efficiency subwoofers and 1 10 inch subwoofer. Each group of coaxial speakers contains 2 speakers, 2×7+4+1=19 speakers. In addition, the Chrysler 300C is also equipped with a set of high-efficiency and energy-saving Class D power amplifiers, which have a voltage of 12V in normal mode. When playing dynamic music, this power amplifier can instantly increase the voltage to 35V to satisfy playback effect. For example, when playing a symphony, it starts with a melodious and lyrical violin solo. The current voltage of the power amplifier is 12V, and the drum sound suddenly appears (for example). In order to satisfy the effect, the power amplifier will be instantly pushed to 35V.
■ Can the Harman Kardon system be retrofitted through the aftermarket?
Many netizens are very concerned that Harman Kardon has official aftermarket services, and Mr. Fu Yundi clearly answered that Harman Kardon currently does not have aftermarket services and does not have any authorized aftermarket service providers. As for the reason, he said that because the audio system requires very detailed and complex adjustments, the aftermarket does not have this condition, so the final effect does not meet the requirements of Harman Kardon, so the aftermarket has not been opened. Especially software such as Logic 7, Clari-Fi, etc., can't be realized through later installation.
Fu Yundi also made a metaphor. If the car you buy is originally equipped with Harman Kardon audio, it can be understood as a delicacy cooked by a professional chef with carefully selected ingredients, and even if you can modify it yourself, you can buy it. To the speakers of Harman Kardon (he also said that such speakers may be of unknown origin), but they are also like fast food. The taste is indeed better than that of coarse tea and light rice, but you can't realize the charm of real Harman Kardon.
I believe that after reading this article, everyone has gained a lot of knowledge and answered many doubts in my mind just like I just interviewed Fu Yundi. In fact, the current competition is not only fierce among car manufacturers, but also fierce in the field of car audio. Harman Kardon has deep attainments in both technical reserves and post-adjustment. Going back to the Chrysler 300C, you can actually experience the 19-speaker Harman Kardon audio for less than 400,000 yuan. It is also quite competitive in the same level. At least at this price, you can’t buy the same Other models of high-end audio systems.
