Acoustic Sensors

Calibration line is AC coupled to the preamplifier input, with 6 dB attenuation. It can be used to test electrical system integrity. An electrical input signal is applied to the cal line (blue) at cable termination. The output signal level is then measured. The output level will be 6 dB less than the input level. Note: the maximum calibration input level = 16 volts peak to peak, 5.7 volts RMS. The calibration line can also be grounded to minimize noise during use, if necessary.

Shield connections are floating (not grounded) at the preamp; they can be grounded at the cable end to minimize noise, if necessary.

The preamp will begin to clip when the acoustic SPL exceeds 165 dB re 1µPa at one meter away.
