Manley Reference Silver

Large condenser tube microphone inspired by the legendary Sony C-37A and built in collaboration with Josephson.


The Manley Silver Tube Microphone is large condenser microphone inspired by the legendary Sony C-37A and built in collaboration with Josephson.

The Manley Silver Tube Microphone uses a capsule designed by David Josephson who has provided a stunning recreation of the C-3 capsule originally used on the C-37 microphone in the ‘50s. This capsule is single-ended and boasts an adjustable acoustic chamber on the back allowing the user to change between omni and cardioid polar patterns. This capsule delivers a rich a creamy tone associated with the original Sony microphone.

Inside the microphone, lies a unique circuit design which combines a FET and vacuum tube cathode used to amplify the signal before hitting Manley’s IRON transformer. This design provides a bit less output than other microphones and can, therefore, accommodate loud sources very well.

The power supply has been specifically designed for audio fidelity with all regulated lines, super low impedance rails and no 50Hz/60Hz ripple component present in the chassis. It works at any voltages between 90V and 250V so all you need to do is plug it in.

This microphone offers a rich and warm sound that will complement female vocals and saxophones particularly well without any boxiness or sibilance. It will also impart its sonic glory on drum overheard with a warm mid frequency response shaving off the harshness produced by cymbals when used with other microphones. Its dark tone means that it can often be used instead of a ribbon microphone.
