The M 320 is a small-diaphragm omnidirectional condenser microphone, perfect for broadcast and audio recording productions
The frequency response of the transmission factor is practically linear for a wide range of sound incidence and has a smooth treble boost rising to about 3 dB between 6 and 10 kHz. lt permits a lifelike recording also at various sound incidence, e.g. announcer in synchronous studios, speaker, blower.
The M 320 is designed for studio applications in radio, television broadcasting and films for live performance and recording of instruments, vocals and speech and sound reinforcement in the professional and semiprofessional market also under adverse acoustic conditions, e.g. in churches.
A new low-noise integrated hybrid circuit and the transformer-less circuit design guarantee an extremely wide dynamic range by a low equivalent loudness level and a high reliability in operation.
RFI susceptibility is very low.
The microphone is powered by a 3-pin XLR connector with the C 70 microphone cable. The power supply is provided by 48 V phantom powering, which is internationally standardized as P 48 in DIN 45596 and IEC 268-15. A two-channel powering is possible with the N 200 power supply.
The finish of the miniature microphone is dark bronze.
lt is recommendable at close-talking to use the wind screen W 20.
