Relatively Fast Response
■ 1/4 inch 4Hz ~ 70kHz, 1.0 MV/PA sound pressure sound field Micro hon The 4944-A is designed to be used near a small closed space coupler or a reflective surface of strength or when it is flashed. This is a 1/4 inch laser -welded 1/4 inch uneven acrobatic sound field micro hon. The preamplifier is connected to the CCLD input conditioner and supports IEEE P1451.4V 0.9 TEDS (Transdusa Electronic Data Sheet). ■ Usage examples ・ High level measurement ・ Measurement of high frequencies ・ Flash mount ・ Array in the wind tunnel ■ Design and robustness The shape of the microphone front is designed to guarantee the excellent microphone performance during flash mounts. The laser welded diaphragm of the microphone housing guarantees the sensitivity resistance to rough handling during flash mounts. ■ Micro -hon data CD Microphones come with a mini CD, including all individual proofreading data and random incidence and freedom correction. UA-0385 1/4 Inch Nise Corn Data is also available. ■ Calibration For sensitivity, the DP-0775 1/4 inch adapter can be attached to the 4228 type pistonphone and can be calibrated at 250Hz. The sound pressure sound field response can be measured by using the DB-0264 adapter with the UA-0033 actuator. The sound pressure sound field response is equal to the actuator response.
