1/4"

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