| Application | Array microphones |
The TEDS (Transducer Electronic Data Sheet)contains information about the complex transfer function, hence enabling applications to calculate corrections for the individual transducer, resulting in more precise measurements. The microphone preamplifier is of the industry standard CCLD (constant current line drive) type for use with a cheap coaxial cable for signal, a power supply, and TEDS.
A rugged protection grid provides an integrated heat shield. The microphone is front-vented for pressure equalization.
Type 4958 is a precision array microphone offering extended TEDS and excellent phase matching and amplitude linearity over a wider frequency range compared to the 10 kHz Array Microphone Type 4957.
