List of accessories available for all variants of this family
This microphone consists of Microphone Type 4954 laser welded to a ¼" microphone preamplifier. The unit is assembled in a clean-room environment and sealed together, after which it is assigned one single type number and one single serial number. This means that the combined unit has better precision and long-time stability, and is handled as one complete unit.
The transducers can be connected to any CCLD input and support IEEE P1451.4 V0.9 TEDS (Transducer Electronic Data Sheet). The unit also contains TEDS, which means that information about the serial number, type and sensitivity is stored within it.
