Hi does the pro mic have SPL calibration?

If not how can I do it without a SPL meter?

Can I do it like this link http://johnr.hifizine.com/2013/03/room-eq-wizard-spl-calibration-without-an-slm/

Also is the XLR cable balanced or unbalanced?

Thank you
Sorry for the late reply, completely missed these questions.

The only ways of calibrations I have experience of is using a specific calibrator or the use of an extra SPL meter. The use of an extra SPL meter is probably the easiest way and less expensive.

I have used this B&K calibrator, but it's crazy expensive.

Here is an alternative for a cheaper version, do not know if it is available worldwide or only in Europe. There has to be other similar options.

The signal is unbalanced, but XLR because the microphone requires some low voltage (not really phantom power).

Do not forget to add the calibration file to adjust for the frequency response.

Thanks Joel wondered if you were on holiday.

Wondered if I could use a Digital Volt Meter with the XLR unbalanced XLR?

Thanks
Yeah, I guess so. I have never used this procedure. I have only used cablibrators as I linked to, which is the preferred choice. It will also account for temperature change.

Sensitivity (re 1000 Hz, 94 dB): 10 mV/Pa
