130 series ICP® array microphones provide an extremely cost-effective method for large
channel count sound pressure measurements.
Multiple array microphones with their excellent
phase characteristics can be combined with the appropriate software to perform measurements
that are not possible with a single microphone.
Typical applications include sound pressure
mapping, beamforming, acoustic mode analysis, near-field acoustic holography, or sound
intensity measurments. To ensure the best performance from your 130 series microphone follow
the installation and operating procedures in this guide. If you have additional questions
concerning the microphone system or applications, call a factory Application Engineer at 716-
684-0001, or your nearest PCB

2.0 Product Description
PCB
®
’s 130 series ICP® Array are integrated systems that include a built-in preamplifier.
Models 130F20, 130F21, and 130F22 are all ¼-inch microphones that provide a 45 mV/Pa
output over an extended 120dB dynamic range. They are ideal for use at frequencies from 20 Hz
to 10 kHz (± 2dB) or 20 kHz (± 5dB). All models are of rugged, stainless steel construction .
