The Josephson C725 provides classic studio microphone performance using a hybrid of vacuum tube and solid state technology, and the classic dual-diaphragm capsule that's used in the C700 and C716 microphones. A separate high voltage regulated power supply is provided, with five switchable patterns and a unique Sun And Moon selector to optimise the signal path. The C725 is suitable for Vocal or Instrument duties.
