• Polar pattern: Switchable omnidirectional - cardioid
• Acoustic mode of operation: Omnidirectional: pressure transducer; Cardioid: pressure gradient transducer.
• Field of application: speech and music; also in acoustically undeveloped rooms. When used in pairs also suitable for stereo.
• Frequency response according to nominal curve: +/- 3 dB
• Frequency response range: 40 - 20,000 Hz
• Cancellation: > 15 dB
• Field-to-noise transfer factor at 1 kHz: >= 0.7 mV/µbar
• Impedance: 850 Ohm (omnidirectional); 1000 Ohm (cardioid)
• Supply voltage: 4.5 V ... 20 V
• Current consumption: <= 150 µA
• Connection to a tape recorder or cassette deck via 5-pin DIN connector with center pin

Using the adapter cable 278a, two GCCM 320 can be connected for stereo recording. The extension cable 391 is used to extend the microphone cables.
