ROGA MI-17 TECHNICAL DATA:

Analog Inpu

These 1/4"-measuring microphones are pressure transducers. The model MI-17 have integrated electronics, and can bedelivered with sensitivities from 10 to 100 mV/Pa at toler-ances of within ±5%. Special custom versions are also pos- sible. Power supplies for the microphones can be either aconstant current source of 2–6 mA (standard version) or a constant voltage source 4–30 Volts. Normally the micro- phones are fitted with BNC-connectors (fem.) allowing standard BNC-BNC cables to be used. Other connectors suchas TNC, SMB, Lemo or µdot are also available on request. These microphones are quite suitable for array applications.
