This trio of Decca modified Neumann M49's is a rare find indeed. Utilizing a k49 capsule in a cardioid pickup pattern designed to be used for classical music. As such,they are extremely sensitive with incredibly low noise
It was a DECCA in house design - and those guys knew their business better than most. Klaus Heyne notes
"All M49 models after 1957 had a “cardioid only” switch built in, to achieve a 4dB s/n improvement [as compared to setting the pattern] remotely, from the power supply.
This trio will be sold as a set so as to not break up their historical and practical value. Includes Pelican case.
Tech Notes: Decca modded. All FET and components used are original from the modification. The mod was carried out by DECCA and substituted the AC701 for a quiet FET, eliminating the need for a PSU and making the system much more reliable and quiet. Microphones all present amazing frequency response, details and low noise.No PSU needed as output connector has been modified to 3 pin XLR only requiring +48V. s/n 340 non original capsule
