    Hosa Technology introduces two new series of power cords, designed specifically for gear outfitted with Neutrik powerCON connectors. When properly installed, these connectors forge a secure connection that prevents accidental disconnects due to tripping over cables or bumping of equipment. PWN-200 Series Power Cords are designed to carry power from a normal wall outlet to a powerCON-equipped device. For those using power distribution boxes equipped with powerCON outputs, PCN-200 Series Power Cords feature powerCON connectors at both ends and are… View this story

    Editor’s Note: This article was originally published in the March/April 2000 issue of Live Sound International, and it still provides a wealth of valuable information on this important topic. Q.) What does a power amplifier do, anyway? A.) In a nutshell, a power amp takes your audio signal and provides both voltage gain and current gain to drive loudspeakers. The voltage gain is necessary because line-level audio runs around a volt, peaking at maybe 8 to 12V, and loudspeakers need… View this story

      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 story

    The Garland Theater in Spokane, Washington opened its doors in 1945. In 1999, Katherine Fritchie purchased the theater, realizing that the treasured venue needed some serious upgrades if it was going to continue to be a vital part of the community. Dedicated to revitalizing theater while maintaining its beloved history, Fritchie turned to local integration firm Hoffman Pro Systems to design and install a new AV system protected, powered and operated by a Furman SmartSequencer. “I have been working with… View this story

    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 story

    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 story

    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 story

    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 story

    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 story
