Microtech Gefell and the next Generation - A little voyage of discovery through the world of microphones

Design your own microphone - Under this motto the children from Gefell kindergarten visited our company

Together with our bat mascot Batty and the sales staff, the children aged 2 to 6 learned what sound waves are and how they work, what sound waves are and how they work, got to know our versatile microphones, e.g. the CMV563, and, of course, to design their own microphones, which now adorn our foyer.

Gefell, 12.09.2025 (PresseBox) - Together with our bat mascot Batty and the sales staff, the children aged 2 to 6 learned what sound waves are and how they work, got to know our versatile microphones, e.g. the CMV563, and, of course, were allowed to speak or shout into a microphone themselves.

The children also designed their own microphones, which now adorn our foyer.

The CMV 563 – M7 is the original reissue of the vintage Gefell CMV 563.

The M7 microphone capsule, developed around the early 1930s, was a key innovation by Georg Neumann & Co. for their early tube microphones, such as the CMV-3 ("Neumann-Flasche") and later the Gefell Vintage-Microphon CMV 563, noted for its excellent signal properties and warm sound of valve microphones that are preferred by vocalists and soloists.

The vacuum tube pre-amplifier is equipped with the EF 86 pentode working as a triode selected for its sonic characteristics.

The new N 61 power supply provides the operating voltage for the vacuum tube. It can be powered from AC mains with a primary voltage of 115 or 230 volts / 50 or 60 Hz. The N 61 is equipped with an on/off switch, a 7-pin Tuchel connector that powers the microphone and a 3-pin XLR connector.

Little explorers visit Microtech Gefell The children starting school at Tanna kindergarten visited us as part of their "Senses" project - a perfect opportunity to discover the world of microphones together with our mascot Batty! As a souvenir, they received a self-printed whistle - and a lovingly designed mural from the children as a thank you.
