NEW from GRAS - Type 46DE: world's smallest ⅛" measurement mic.

Extremely versatile ⅛" pressure microphone - the worlds smallest measurement mic.


The Type 46DE is a low-sensitivity pressure microphone set for sound measurements at high levels and high frequencies. It consists of a Type 40DD ⅛" pressure microphone and a Type 26CE ⅛" preamplifier.


Normally a ⅛" microphone is used with a ¼" preamplifier, but for Type 46DE GRAS has developed a ⅛" preamplifier, making the Type 46DE microphone set the world's smallest.


Ideal for using in very confined spaces and location where it is very difficult to locate a measurement microphone.  Contact us to find out more about the GRAS Type 46DE microphone set.
