Cardioid Condenser Microphone

The S700 is a large-diaphragm FET condenser with an unusual end-address design. The mic is essentially a solid-state version of CharterOak’s S600 tube mic, and was initially built as a voiceover and broadcast microphone.

Both use CharterOak’s “S-3” capsule — an edge-terminated 35mm capsule with a single 26mm diaphragm made of 6-micron Mylar. This capsule is an original design from CharterOak.

[The S700] employs an internal plosive shield of Saati-Tech Hyphobe Acoustex, and the capsule is installed in a slightly different way in order to provide more linear bass response for use in VO and broadcast applications.

Like most of CharterOak’s microphones, the S700 uses a transformer to balance the mic’s output. The transformer is manufactured in the US.

The S700 includes an elastic shockmount and a locking flight case.
