The impaq analyzer supports Lemo 7 pin microphone preamplifier for either 200V or 0V microphones. You may plug in up to 4 microphones for acoustic measurements.

Because impaq does cross channel measurement, you may plug in a sound Intensity probe for sound intensity measurement in the field.

The data stored in the impaq can be easily transferred to a PC via the USB port or a CF card reader, and imported by a post analysis software like ME』Scope for sound intensity contour display.
