Detachable-Capsule Tube Condenser Microphone

MTG announced in 2011 a new recreation of the famous Neumann CMV 563, a bottle-style tube microphone with detachable capsules.

The new microphone uses the EF86-based tube amplifier circuit from the UM 92.1 S microphone, which MTG describes as the modern descendant of the original CMV 563 circuit. Presumably the EMI/RFI circuitry from the UM92.1S remains in place.

The mic’s output transformer is manufactured in Germany to MTG’s specifications. It is the same transformer as found in the UM 92.1.

MTG is promoting the CMV 563 reissue via a dedicated website,, which chronicles the month-to-month production schedule from initial presentation through capsule development, circuitry work, measuring and documentation, with final delivery scheduled for July 2012. The company promises to update the site monthly with the latest information and photos depicting the production process.

The high price is based on the cost of developing the new M7S capsule head, which incorporates MTG’s standard PVC-membrane M7 capsule within a detachable headbasket.

Backwards compatibility with historical Neumann M7S/M8S/M9S screw mounts is retained, allowing the new MTG M7S capsule head to be used on old CMV 563’s, and older Neumann “S”-type screw-on capsule heads to be used on the 2011 CMV-563.
