The Elektomesstechnik 140 is a plate [[Reverb]] from 1957. From [The History of EMT and Plate Reverb](https://www.wikiaudio.org/emt-140-plate-reverb/): > These metal plates, more than anything else, allowed higher frequencies to travel much faster than the lower frequencies. This has a lot to do with why we hear brightness when we listen to the sound of the EMT 140 reverb. [Arturia Rev PLATE-140](https://www.arturia.com/products/software-effects/reverbs-bundle/revplate-140) and [Little Plate](https://www.soundtoys.com/product/little-plate/) are nice [[Virtual Studio Technology|VSTs]] for plate [[Reverb]]. From [The TAB/Telefunken V72/V76 Mic Pre](https://vintageking.com/tab-telefunken-v72-v76-mic-pre): > The city of Hamburg, West Germany was home to both the Broadcast Technology Institute / Rundfunktechnische Institut (RTI) and the North West German Radio/Nordwestdeutscher Rundfunk (NWDR). Together the RTI (later renamed IRT) and NWDR created all-new standards for broadcast equipment, including preamplifiers. These standards were later enshrined in the famous "Braunbuch" (Brown Book). > The V72 was developed by a team of engineers at the NWDR under the direction of Professor Nestler, who had once been in charge of R&D at the famous Electro Acoustic Lab (ELA) of AEG/Telefunken. The team at NWDR also developed many other famous audio products such as the EMT 140 plate reverb, the Hiller MSC2 vacuum tube, and the Neumann M49 microphone and KK47 capsule, all of which were licensed to or improved upon by these namesake companies. So EMT 140 and [[Neold V76U73]] are related.
