Typical applications and use
- Production-line testing of drivers, receivers, and microspeakers
- Sound-scape recording in array configurations
- Multichannel measurements (analysis)
The cost-effectiveness of the 40PP-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-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 G.R.A.S. 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.
Calibration is easy with a G.R.A.S. pistonphone, such as the G.R.A.S. 42AA, together with a ¼" microphone adapter.
Before leaving the factory, G.R.A.S. products are tested and calibrated by G.R.A.S., and an individual test certificate is included with the product.
G.R.A.S. offers 3 years warranty against defective materials and workmanship.
