1、3 RadioFans.CN 收音机爱 好者资料库 23 Unrelenting quality standards Within a decade, Lab.gruppen had expanded to become a major supplier of power amplifiers throughout Europe, and started making significant inroads into the world market. Demand often threatened to outstrip supply, but quality control standar

2、ds never were compromised in order to increase production levels. With every new product, and at every stage of expansion, Lab.gruppen took pride in maintaining the highest levels of traditional Swedish craftsmanship. Only after a larger and highly efficient manufacturing facility still in Kungsback

3、a came online was product distribution fully expanded worldwide. Lab.gruppen continued to build on its foundation in touring sound applications with the pristine sound and bulletproof reliability of the fP Series. With introduction of the FP+ Series Lab.gruppen dramatically boosted power density and

4、 added compatibility with NomadLink network control. Responding to increasing demand from the systems integration market, Lab.gruppen introduced the C Series, a range of multi-channel units designed and fitted for installation applications also featuring NomadLink control. Lab.gruppen + Lake: The ul

5、timate in power and control In 2006, Dolby Laboratories and Lab.gruppen announced an agreement to incorporate Lake Processing into the forthcoming PLMTM Series of Powered Loudspeaker ManagementTM systems. The first Lab.gruppen product to incorporate Lake processing, the PLM 10000Q, was introduced in

6、 2007. When Dolby decided to exit the live sound market, Lab.gruppen acquired both the Lake trademarks and exclusive rights for use of Dolby Lake Processor technology for the touring and permanent sound reinforcement markets. Both divisions are now headquartered in Kungsbacka. First drawing of Class

7、 TD circuit by Kenneth Andersson Lab.gruppen co-founder Kenneth Andersson Lab.gruppen co-founder Dan Bavholm Passion, innovation and Swedish craftsmanship In 1979, Kenneth Andersson and Dan Bavholm established Lab.gruppen while working out of a cramped electronics repair shop in Kungsbacka, Sweden.

8、With a knack for creative circuit design and a passion for better sound, they set about developing new audio products beginning with guitar amplifiers that soon evolved into highly regarded professional power amplifiers. Within a remarkably short time, Lab.gruppen had built a loyal customer base amo

9、ng leading Swedish sound rental companies. Not content with merely refining existing designs, the founders continually pushed the envelope of audio amplifier design. New technologies boosted output power while at the same time reducing weight and improving reliability under stress. Noteworthy among

10、these developments were the patented Class TD output stage, Regulated Switch Mode Power Supply (R.SMPS), the Intercooler heat dispersion system, and innovative limiter circuits that tailor amplifier output parameters for optimum performance with the connected load.

11、 edge amplifier development Lab.gruppen power amplifiers and PLM Series Powered Loudspeaker Management systems have earned worldwide recognition for outstanding sound quality and remarkable durability in both touring and installed applications. At the core of this enviable reputation is Lab.gruppens

12、 commitment to innovation, firmly established by the company founders and continuing with todays extensive R the amplifiers simply use the dynamic behavior of the input signal and “recharge” between the peaks. Lowering the “electricity penalty” With already high energy costs moving higher in nearly

13、every part of the world, the total amount of electricity required to power an amplifier must be factored in to the total cost of ownership and operation. When electricity costs are factored into the equation, Lab.gruppen E Series amplifiers quickly recoup any marginally higher initial costs within t

14、he first few years of operation, when compared to several popular installation amplifiers using conventional technologies. Depending on the specific application and on/off cycle periods, conventional amplifiers may impose an “electricity penalty” up to three times that of the E Series. Many of them

15、will cost more in electricity over 6 years of use than they initially cost to purchase! Lab.gruppens amplifier platforms, often in combination with Lake technology, can be found the world over and across a multitude of applications ranging from arena or night club installations to touring concert so

16、und. Integration is at the heart of the product range. Realizing the performance advantages of Lab.gruppen products is hassle-free, whatever the system configuration and irrespective of the other components. In touring sound, the seamless integration of Lake Processing and Lab.gruppen amplification

17、powered the excitement of U2s globe-spanning 360 tour, with more than 150 PLM Series Powered Loudspeaker Management systems driving Clair loudspeaker arrays. In the installation market, the PLM Series brought the same advantages to BC Place in Vancouver, Canada, where the former Olympic venue employ

18、s 160 PLM Series units. The advantages of Lake Processing and Lab.gruppen amplification are often realized when coupled to loudspeakers from sister company Tannoy. A recent example is at Englands famed Ascot Racecourse, where PLM Series units drive a loudspeaker system comprising of Tannoy V Series,

19、 VQ Series and QFlex. Here, the combination of Lab.gruppen and Tannoy delivered measurable performance, reliability and cost advantages that simply couldnt be achieved by alternative configurations. This approach is echoed in smaller installations, such as retail outlets, bars, clubs and restaurants

20、. At Californias Cannery Row Brewing Company, the combination of Lab.gruppen C Series amplifiers along with Tannoy surface-mount and ceiling speakers contribute to a festive atmosphere that builds repeat business.
