TDK Introduces Ultra-Thin Noise Suppression Permalloy Sheets

TDK Corporation extended its Flexield family of permalloy thin film sheets with the new IPM01 series, which features high-permeability and high loss in a lightweight and 0.006 mm ultra-thin design. This new material made possible due to TDK's proprietary manufacturing method, effectively shields lower-frequency band noise, which is becoming a growing issue in electric vehicles (EVs). Mass production of the product began May 2024.

With the audio market increasingly using digital data interfaces for the most demanding applications, Wireworld Cable Technology, one of the world's most respected brands of high performance audio and video cables, announced the release of their second generation Ethernet patch cables. The new “Series 8” patented flat design uses higher density triple-layer shields and quieter Composilex 3 insulation to maximize audible and visible performance.

Io Audio Technologies, a division of Knight Electronics, Inc., has developed a family of 3-pin XLR cables that offer high-quality design and high performance with pricing that speaks for itself. Available in three grades, Premium, Professional and Performance, these audio cables deliver high-quality sound performance with different budgets in mind. The 3-pin XLR cable family provides excellent EMI resistance for low noise performance and uses rugged locking connectors to ensure safe and secure connectivity.

Inspired by a presentation by Bill Whitlock, President of Jensen Transformers - a three-hour tutorial seminar titled “Audio System Grounding and Shielding: An Overview” - during the Audio Engineering Society convention in New York in 2007, Gary Galo decided to investigate a little more into the subject and do some reviews of the mentioned equipment.

In this article, author Pete Millett explores the different types of power transformers, and why you might choose to use each type in audio equipment. The article addresses issues with low-frequency (50–60Hz) line transformers, but many of the same issues apply to audio-frequency transformers as well.
