United Studio Technologies Introduces UT FET47 Large Diaphragm Condenser Studio Microphone

A faithful reproduction of a legendary classic studio microphone workhorse. This is how United Studio Technologies describes its first product, the UT FET47. Aimed at both professional and project-level recording, as well as the broadcast and voiceover market, the UT FET47 is hand-built in Baton Rouge, Louisiana, and features a custom output transformer designed by Cinemag and a Heiserman HZ-series ‘K47’ German-style capsule.

In this article Scott Dorsey tells us how to repair Switching Mode power supplies. As he explains, "there are a lot of books and articles out there about how to design a switching supply, but not many on fixing them. As switching supplies become ubiquitous in electronic devices today, it becomes that much more important to understand how they work and just as importantly how they fail."

In this article, Joel Hatch explains how to build a variable frequency synchronous motor controller to control turntable speed. Now that turntables are back in force, this excellent project not only allows some knowledge about a vital part of the motor's rotational speed adjustment, but it also dives into one of the most crucial aspects of a record player for anyone interested in a little DIY or restoration projects.

Get hands-on with audioXpress November 2016. Read about the experience of recording a jazz repertoire with a full orchestra… direct-to-disk. We review KEMET’s PEG124 Series of electrolytic capacitors and the Dirac Live room correction software. Bruce Brown details the restoration of a pair of Fairchild 275 tube amps. We interview Dennis Foley from Acoustic Fields and we provide backstage access to Parts Express.

Fairchild announced that its FUSB302 family of USB Type-C controllers are the industry’s first to be compatible with the latest updates to the USB Type-C standard, including Power Delivery (PD) specification - Type-C PD 1.2 Standard. This enables manufacturers using the FUSB302 to easily support all current and previous versions of the USB Type-C specifications in their products.

This month, audioXpress features an updated version of the Willow amplifier, especially designed for the DIY community, and a three-way loudspeaker project with an external active crossover network. We visited Eighteen Sound in Italy, discuss experiments with Dolby Atmos, audio networking development based on Audinate’s Dante technology and learn how to measure Reverberation Time (RT). And if you are interested in recreations of the famous Fairchild compressor/limiters, rectifier tubes, and how to properly test tubes, don’t miss this month’s audioXpress.

It’s hard to keep track how semiconductor companies evolve given the pace of mergers, spin-offs and acquisitions. ON Semiconductor, a relatively young player in the industry but increasingly crucial for the audio industry, announced it will acquire one of the most iconic companies, Fairchild Semiconductor, for $2.4 Billion in Cash. The acquisition creates the global leader in the power semiconductor market, they say.

Fairchild announced a comprehensive line of USB Type-C solutions that meet a wide range of requirements so manufacturers can accelerate time-to-market of new-generation USB-C products. The six new devices all have smaller size and lower power requirements than existing alternatives.
