Design
The cost-effectiveness of the 40PP-10-S1 is a key consideration when setting up multiple production lines. Close manufacturing tolerances provide the 40PP-S1 with a high degree of interchangeability – a major advantage when used in production-line test setups.
The robust standard BNC connector of the 40PP-10-S1 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 Electronic 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.
Warranty
GRAS offers 3 years warranty against defective materials and workmanship.
