If the sound level within the chamber, or the noise emitted by DUT has to measured, we offer a an audio system that can be calibrated.
PONTIS audio transmission systems makes sure that the signal at out put in the control is exactly the signal at the input plus a defined gain.
If there is a requirement to connect a high quality microphone (with 48V phantom power), the complete line can also be calibrated.
fully digital transmission (S/P-DIF output)
