HARMAN JBL Synthesis® Now Offers Its ARCOS Adaptive Room Correction and Optimization System To Achieve A New Level of Accuracy For Home Audio

April 13, 2011 – NORTHRIDGE, California — HARMAN JBL Synthesis today announced it is now shipping its ARCOS Adaptive Room Correction and Optimization System, an integrated software and hardware package that provides a new level of calibration accuracy in setting up a JBL Synthesis multichannel audio system. ARCOS utilizes a number of newly developed DSP algorithms, measurement and analysis techniques to achieve unprecedented frequency response correction and system performance in any room.

ARCOS represents the evolution of 20 years of room measurement and auto frequency response correction for use within real home theater environments. All rooms exhibit resonances that occur when an audio source such as a loudspeaker is played. These resonances or room modes emphasize some frequencies and attenuate others, and are typically very significant in magnitude. ARCOS compensates for these irregularities more comprehensively and with greater accuracy than has been available before, achieving an optimized response at the actual listening positions from all of the loudspeakers. ARCOS also provides time delay correction so the signals from all the speakers arrive at the listener’s ears at the same time for accurate imaging, along with speaker-level calibration and additional benefits.
The JBL Synthesis ARCOS system builds upon the HARMAN Audio Test System (H.A.T.S.) hardware and software suite used worldwide by HARMAN acoustics and transducer research engineers for the measurement and design of loudspeaker systems. It also incorporates and improves upon the functionality of the JBL Synthesis SDEC digital equalizer hardware and software. ARCOS adds a new on-screen graphical user interface (GUI) and a fully integrated Wizard, which is easier and faster to use than previous systems and which will take a user through Sound Field Management (SFM), Room EQ, subwoofer and mains blending, system and preamp setup, speaker functional test, source DVD/Blu-Ray setup and listening test steps. The system’s algorithms incorporate the findings of numerous peer-reviewed, published research papers by HARMAN engineers.
One of the major benefits of ARCOS is its ability to calibrate larger areas of the room rather than an individual location, so more listeners can enjoy the sonic “sweet spot.” ARCOS utilizes eight microphones throughout the room to measure room and speaker acoustics, and supports the exclusive HARMAN Sound Field Management (SFM) system that minimizes seat-to-seat variation in bass response in a home theater system.
ARCOS features multi-step AutoEQ that uses more than 200 bands of fully parametric digital equalization that can be adjusted from 1/100 octave to more than 4 octaves wide between 20Hz – 20kHz to correct for dips and peaks throughout the frequency range. AutoEQ can operate on an almost unlimited number of speakers and drivers and precisely match their frequency and tonal balance. After the system is calibrated, ARCOS displays the actual corrected room curve – not a calculated measurement as provided by almost all other systems.
As any installer knows, matching a subwoofer or especially multiple subwoofers with the main speakers in a system can be difficult. ARCOS incorporates a new, exclusive AutoCurveSum process that correctly optimizes the crossover blend between the subwoofers and any number of main speakers, by using a combination of delay and phase filters. ARCOS is the first product to incorporate AutoCurveSum.
ARCOS incorporates a host of additional advanced features, including automatic speaker-level and distance calculations, 96kHz or 48kHz analog-to-digital measurement conversion (depending on the speed of the connected PC), a Java-based GUI for future expansion into multiple computer platforms (WindowsXP version available now, Windows7 available soon), and the option to make the calibration process either totally automated or completely manual if desired. Communication between the measurement hardware and the equalizer module take place over standard Ethernet cable, and ARCOS utilizes the HARMAN HiQnet® communication protocol for end-to-end connectivity and future expansion to other HARMAN systems.
The JBL Synthesis ARCOS Adaptive Room Correction and Optimization System is supplied with all hardware, measurement microphones, software and accessories needed to calibrate a JBL Synthesis multichannel audio system. ARCOS is currently available to all authorized JBL Synthesis dealers and systems integrators.

絕對是必要手段..就以Hi End精神來講.
燒友~幾十幾百萬時間/精力.都投下去了.相對便宜到不像話的測量為何不能試?
況且網上還有熱心專研-無償付出的專業人士..:)
1-不太同意.
系統永遠是主角.底子不夠好.再怎樣調/處理..還是有限.
2-同意一半.
$$$.還是.$$$.:P.所知本站高人中.
好像只有站長公開稱許過的..兩位 大咖級人物..有此實力/能耐..!!
但是大部份用家仍然專致汲營.想要提升自我表現..
不少本站同好.
家中都有樂器及學樂器的人..應該可以提出來討論相關心得.
倒是在下所認識的.音樂家級人物(也玩音響.).通常沒有純玩音響的那麼講究效果噎.?|-)
是所謂心境超脫..而達.??
真要找或諮詢.市場上也是有一些標榜專門音響空間處理的公司.
但在下想.大部份用家..不想也不會去試那一塊..
寧願自己試.自己幹.自己爽..反正是自己聽居大多數..:P
這也是..居家需求與專用獨立的矛盾/拉踞之處..
事前處理得好..萬幸難得..:):D
就所知.會po文/心得報導已經很有心..願意公開分享已經了不起..
要達成 wu兄標準者..少之又少呀..!!
但是..
音響商家最常掛嘴邊一句話..
這套系統.搬回府上空間..一定更好聽.
商家空間.私以為還是以促進"產品銷售"為最主要..
真要實際測量起來..|-)8)..真還難..説?
音響器材~是科學相關的.
聲學測量~也是科學相關的.
不太好..一元論..或二分法吧..?!
沒測量.就是相對傳統的玩法..弄得好聲者應該~也有.
有測量.分析.印證..相對找到系統+空間的需要處理"要點"..機會大很多..:|
起碼.立即且處於"盲點"的問題..會清楚呈現.?!
有人一直做這般"不討好"的事.
需要累積案例..統計分析..就像醫學上..臨床試驗?:P.要時間.要精力..
我們大家談論許久.
最難的..就是將測量結果(圖表.數據..)和聆聽感受做一個適當連結與對照..
這事兒..吃力又不討喜..
最怕就是..丟資料而不消化或整理(要考慮到大部份玩家感受程度.).旁人難明呀.
或自顧自..只發(給)問.不將已知或僅知的東西分享..
請 大大多注意-思量..得罪望諒..(blush):P:o.
敝臆想,有一可移動空間且有一套經多數認可水準音響.
如有不同意者可提供器材來調配,猜將有數据提供,或是可表現出自
家未曾出現的效果,這樣網友有福了.|-)|-)|-)|-)
