Studiomaster has published details of its new Class AD Polyphase proprietary amplifier development in a technical reference document on the company’s website. First announced at this year’s Prolight+Sound exhibition in Frankfurt, the company states that the technology provides improvements in sound quality, efficiency and power density over current Class D designs. The new topology combines a number of design innovations with a Studiomaster patented “polyphase” output stage, with the goal of providing the equivalent sonic performance of an analog design…

It’s no secret an engineer’s knowledge of his tools is a source of great power. Any time I’m preparing for a recording session or live sound gig, the first thing I set upon once I determine the makeup of the ensemble and the equipment at my disposal is to determine how best to utilize the available microphones. One of the best tools any engineer has in this task are manufacturer specifications. However, many microphone manufacturer websites are laden with Flash…

Outline, the makers of high quality, industry leading speaker systems for touring, installation and studio applications, will showcase its iMode Intelligent Digital Loudspeaker Control Platform at InfoComm 2011 (Booth 683). iMode technology embeds a Linux-based CPU - with integrated DSP chip, parameter control software and web server - right into its powered speaker systems, thereby streamlining setup and control by eliminating the outboard gear between the console and power amplifier. Winner of a coveted PLASA Innovation Award in 2010, iMode…

Several years ago I was managing a touring sound company, and we decided to take a stab at contracting. Because our expertise was in large systems, we focused on big installations like stadiums. In those days, most sports facilities were being designed with 12-channel boards, wimpy amplification and loudspeaker clusters kindly called “flying junkyards.” We perceived a huge gap between what was being offered to the average sports fan and what we were consistently providing to other entertainment patrons at…

Picture Miami/Fort Lauderdale in the ‘70s: small and quiet, lots of birds, flowers and trees. Lots of artists too. There were loads of clubs and hotels to gig at, and the whole area was an inexpensive place to live with a great climate. As a community of players, we shared ideas and band gigs, and had a great time musically and socially. Three natives of Fort Lauderdale had a trio called “Woodchuck” who played Hammond B3, guitar and drums. They…

Determining which power amplifier is appropriate for a specific application is not as easy as one may think. To fully understand what needs to be considered, three specific case studies will be outlined: • A client wants to play folk music in a coffee shop. How much amplifier power do they need? • A rock group will be playing in a 2,000-seat concert hall. How many watts will you need to provide? • A jazz-fusion group bought some PA loudspeakers.…

It’s an answer to a sound company’s prayers: low-weight, cool-running power amplifiers with low current draw. Look for switching power supplies in power amps, and switch-mode power amplifiers. Compared to a standard amplifier power supply, the benefits of a switch-mode (switching) supply are lower size and weight. Compared to a standard analog power amplifier, a switching amp tends to run cooler and draw less current because it is so efficient. In addition, the amp can be smaller and lighter because…

Many professional audio manufacturers are now actively producing their own proprietary network connection and control systems, thus enabling users to create and control products within the audio chain. While not a particularly new concept (Crown, for example, started the trend in the 1990s with the IQ computer control system for its amplifiers), recent years have seen a plethora of new solutions. Therefore, to partner this article on interconnection options, here’s a brief overview on the control and distribution solutions currently…

INTRODUCTION TO THE LAKE CONTOUR by Bruce Jackson In 1997, I approached Roy and Troy Clair with an idea for a new digital solution that I believed could, if pursued, put Clair Bros ahead of their competition. One thing I was bringing to the project was a history of developing products in the lab combined with decades of live sound mixing experience. And, my long relationship with Roy and Troy, dating back to 1970 when I sold my sound company…

Yamaha Corporation Japan and Yamaha Commercial Audio Systems have announced a strategic partnership with Rupert Neve Designs, based on both parties involvement with VCM (Virtual Circuitry Modeling) technology. VCM is an exclusive Yamaha digital technology, enabling engineers to achieve stunning sonic and musical performance by actually modeling the individual characteristics of a multitude of parts and components contributing to the final sound of original analog circuitry. VCM recreates the sound and characteristics of several classic compression and EQ units and…
