The super-cardioid e 614 is a permantly polarized condenser microphone designed for demanding applications which require a wide frequency response, high SPL, fast transient response and a compact design. With its frequency response of 40 Hz to 20 kHz, the e 614 is able to capture the full sound of the instrument, while its super-cardioid pick-up pattern isolates the microphone from other on-stage signals.
