Array Microphone Type 40PL 1

Product catalog summary

Overview: The G.R.A.S. Array Microphone Type 40PL is designed for general-purpose measurements in arrays and matrices. It features a wide frequency range up to 20 kHz and a dynamic range up to 150 dB. The microphone includes an integrated CCP preamplifier and a TEDS chip for easy programming and interchangeability.

Specifications:

Nominal Sensitivity: 10 mV/Pa ±3dB at 250Hz
Frequency Response: ±3 dB from 10 Hz to 100 Hz, ±1 dB from 100 Hz to 3 kHz, ±2 dB from 100 Hz to 10 kHz, ±3 dB from 10 kHz to 20 kHz
Dynamic Range: Max 150 dB without clipping, thermal noise < 32 dBA
Phase Match: ±3° from 100 Hz to 3 kHz, ±5° from 3 kHz to 5 kHz
Temperature Range: -10 °C to +50 °C
Output Impedance: < 50 Ω
Dimensions: Length 60.0 mm, Diameter 7.0 mm, Weight 5.5 g
Power Supply: 2 mA to 20 mA (typically 4 mA)

Applications: Suitable for multi-channel measurements, sound-field analyses, sound-power measurements, and concurrent spatial and transient measurements.

Calibration: Can be calibrated using G.R.A.S. pistonphones such as Type 42AP. Each microphone is individually checked and calibrated before leaving the factory.

Accessories: Includes CCP supply Type 12AL, windscreen set AM0364, rain-protection cap RA0092, array modules PR0001 and PR0002, and various cables. Pistonphones and sound calibrators are also available.

Additional Information: The microphone's low cost is advantageous for setups requiring multiple concurrent measurements. The TEDS chip enhances interchangeability, making it ideal for use in arrays and matrices.
