Measurement Microphone MM 310
The 1/4” Measuring Microphone MM 310 offers facilities for the use of a high-quality prepolarized measuring microphone capsule type MK 301 E on measuring systems with IEPE inputs. Typical applications like array arrangements and covered area measuring procedures, e.g. automotive acoustics, can be taken into account.

Request a QuoteContact usThe measuring microphone is connected to the measuring channels via a fixed microdot connector with microdot cables or usual BNC cables via a microdot-BNC adapter. The measuring microphone preamplifier has an integrated memory for microphone identification. Microphone data can be entered and read by the manufacturer/user by using the memory (IEEE P1451.4 TEDS editor).
The microphone holder MH 64 with 1/4” cone shaped adaptor is recommended for mounting. The 1/4” measuring microphone capsule accessories, e.g. windscreen etc., can be used additionally.
The measuring microphone can be calibrated with the Pistonphone type 5002 or other current sound pressure calibrators with an 1/4″ adapter.
