Description
Microphone Type 4988-A is a 1/4″ prepolarized pressure-field microphone laser welded to 1/4″ CCLD preamplifier. The preamplifier connects to CCLD input conditioning and supports IEEEP1451.4 V1.0 Transducer Electronic Data Sheet (TEDS).
It is an all-titanium design that ensures maximum resistance to corrosion and minimum sensitivity to magnetic fields.
