Measurement Microphone MM 310

Measurement Microphone MM 310

Description

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.

The 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.
