      One of the most confusing subjects in audio? Loudspeaker power ratings. It’s generally accepted that a large loudspeaker power rating is a sign of quality and something to be desired. And it’s the performance metric that probably has the greatest influence on the consumer’s buying decision. But a closer look reveals that power rating is far less significant than other metrics regarding the performance of the loudspeaker. The term “power rating” requires further explanation to avoid misunderstanding. It’s tempting… View this post

    LynTec announces the new Input/Output-Relay (I/O-R) board for the Remote Power Controller (RPC) platform. The I/O-R board expands RPC control options to include control for high-current contactors and UPS outlets, giving users more flexibility to connect and control complex systems on a single control platform, instead of using multiple control systems. This capability dramatically simplifies control setup and equipment operation. “High-current contactor control and outlet control are important to system designers as they add more UPS protection to their systems… View this post

    A power amplifier is a device for making a larger, more powerful signal out of a small, weak signal. It was on February 18, 1908 that Lee DeForest was granted U.S. Patent No. 879,532 titled “space telegraphy,” but in actuality, the patent was for a vacuum tube triode amplifier that DeForest called the “audion amplifier.” For the first time it was possible to amplify signals. The first amps were developed to support radio. Later, other applications were developed. All electronics… View this post

    LynTec announces the release of a new white paper titled “New Federal Distribution Transformer Regulations Coming in 2016.” Written by Alan Tschirner, vice president and general manager of LynTec, the document highlights the changes being made by the Department of Energy (DOE) to existing regulations on distribution transformers, and how those changes will make business more costly for manufacturers and audio professionals alike. Audio consultants regularly use distribution transformers to isolate installed sound systems from the rest of a building’s… View this post

    This article is provided by Gary   In this ever evolving world of more, more, more, better, better, better, when is good enough, good enough? Is it really an absolute necessity to update or upgrade my 15-year-old sound system?  The working life of a sound system can extend well beyond 20 years, and I’ve personally seen systems 30 to 40 years old still in use and functioning quite well. The question deserves considerable thought, and begs a slew of… View this post

    A new sound reinforcement system serving both traditional and contemporary services at Good Shepherd Lutheran Church, located approximately 20 miles due west of Minneapolis on the shores of Lake Minnetonka, is driven by Powersoft M Series power amplification.  Minneapolis-based Excel AV Group handled the system design for the 350-capacity sanctuary. The room is relatively square in shape with one quadrant comprising the altar, while on the exact opposite side are the musicians and the mixing area, which consists of a… View this post

    LynTec announces the CTR Series of high-current latching contactor panels for the company’s RPC Series controllers. In conjunction with the controllers, the CTR panels give users the option to control loads — either individually or as part of a sequencing group — that require more power than the maximum 30 amps a motorized circuit breaker can provide. “For some customers, installations are getting more complex, and current loads are getting more demanding. Meanwhile, changes in technology are leading to new… View this post

    To attract the event planners and meeting managers, the Westin Long Beach Hotel in Long Beach, California, recently transformed its large ballroom into a 4-room convertible space with divisible walls. The hotel turned to local integration firm Spinitar to incorporate the latest audio system and technology including equipment protection from Furman. According to Rudy Zavala, associate systems designer at the firm, the goal of the installation came down to three things: simplicity, functionality and reliability. “One big ballroom is great… View this post
