TECHNICAL INFORMATION

92dB SPL measure at 1 mW input signal, 1 kHz, in Mono mode

Mono mode: 300 Ohms ON and OFF
Stereo mode: 600 Ohms ON and OFF

RTCA-214a range: 300 to 3500Hz
Extended range: 40Hz to 15kHz 

-27dBV (+/- 2.5dB) at 94dB SPL (1 Pa), measured at 6mm 

distance from artificial mouth, across 220 Ohms load resistor 

and biased with 12 Vdc via 470 Ohms resistor. 

Operating bias voltage range: 4 to 28 VDC.

105 dBC SPL for full active noise reduction performance

Two (2) AA alkaline batteries

45 hours in typical commercial jet aircraft noise. Duration 

varies with battery age, ambient noise levels, temperature, 

ear cushion seal, and use of the Bluetooth feature.

Aircraft power voltage range: 10 to 32 VDC
