B&K FAMILY 4988 Microphone Set

1/4″ PRESSURE-FIELD MICROPHONE WITH CCLD PREAMPLIFIER, PREPOLARIZED

Pressure-field microphone for measurements in small, closed couplers, close to hard reflective surfaces, or flush-mounted, with a frequency response of 20 Hz to 20 kHz.

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.
