GRAS 40PP CCP Free-field QC Microphone

GRAS 40PP CCP Free-field QC Microphone

0,00 kr.

The cost-effectiveness of the 40PP is a key consideration when setting up multiple production lines. Close manufacturing tolerances provide the 40PP with a high degree of interchangeability – a major advantage when used in production-line test setups.

GRAS 40PP CCP Free-field QC Microphone

Typical applications and use

  • Production-line testing of drivers, receivers, and microspeakers
  • Sound-scape recording in array configurations
  • Multichannel measurements (analysis)

Design

The cost-effectiveness of the 40PP is a key consideration when setting up multiple production lines. Close manufacturing tolerances provide the 40PP with a high degree of interchangeability – a major advantage when used in production-line test setups.

The robust standard BNC connector of the 40PP ensures an easy-to-handle setup and supports the use of standard RG58 cables all the way from the microphone to the input module.

The integrated CCP (Constant Current Power) preamplifier requires a constant-current power supply, such as the GRAS 12AL 1-Channel CCP Power Module with A-Weighting filter, or any other CCP compatible power supply or input module. The built-in TEDS (Transducer Electronid Data Sheet, according to IEEE 1451.4) chip provides information about the microphone that can be used by systems designed for use with TEDS.

Microphone Calibration

Calibration is easy with a GRAS pistonphone, such as the GRAS 42AA, together with a ¼” microphone adapter.

Before leaving the factory, GRAS products are tested and calibrated by GRAS, and an individual test certificate is included with the product.

GRAS Sound & Vibration continually strives to improve the quality of our products for our customers; therefore, the specifications and accessories are subject to change.
