Ever wondered how diodes can be used to compress audio signals like in the famous old studio consoles by Neve or outboard units old and new? Unfortunately good articles on the topic are few and far around. One that’s worth reading concerning compressors using diode bridge rectifiers can be found here (it’s full of Ads unfortunately): https://www.whippedcreamsounds.com/diode-bridge-compressor/

A much better article on VCAs in general also describes the use of diodes and vari-mu tubes among all other common designs using components from LDRs (opto) to ICs (what most people in the professional audio and studio world call “VCA” compressors collectively) and describes why and how other compressors use these components to achieve compression and limiting, design drawbacks and common distortion reasons as well as the necessary technical background and examples: https://sound-au.com/articles/vca-techniques.html (website highly recommended for audio enthusiasts)

In 1966, Neumann GmbH presented a new type of transistorized microphone to the Norwegian 
Broadcasting Corporation, NRK. Norwegian Radio had requested phantom-powered operation.
Since NRK already had 48-volt power available in their studios for their emergency lighting
systems, this voltage was used for powering the new microphones (model KM 84), and is the 
origin of 48-volt phantom power. This arrangement was later standardized in DIN 45596.

It’s also advised to read the Technical Information and especially Caveats section on the Wikipedia page on Phantom power.

2. Link Audio 312 clones modded with parallel compression, saturation, tape sim and/or custom opamps

New Prototypes:

• We’ve received the first batch of five active summing units for Tascam/DSUB25 to XLR/TRS Combo Jack using a TI NE5332ADR opamp to test. Waiting on PC-ABS 3D printed cases for the active and passive summing prototypes

At the moment some pictures and sites don’t render optimally on mobile platforms like smartphone browsers. We’re working on fixing this. We thought we should finally get the website online instead of moving the release date further back, so we have some info online right away. Most of the important information and contact details, shop etc. is already on the site.

Whats to come

We’ll add more content on analog audio gear, recording, tracking, mixing and mastering techniques in the analog domain as well as with hybrid set-ups. Extend the About Us section regarding the background of our namesake. We’ll also add a rental list and agreement and more information on custom pieces we’ve designed from the ground up or modified for customers.

Hope to see you back here soon!
