Hello friends

I have a new Behringer ECM8000 microphone that I want to use for SPL measurements. I need to do that its sensitivity in mV/Pa.

The attached technical specifications sheet says the sensitivity is 70 dB (positive and without any other unit). I thought it was an error given that sensitivities are generally a negative value.


So, I contacted Behringer support asking the mV/Pa value and the answer was:


70 dBV = .316 mV/Pa


I think 0.316 mV/Pa is a really low sensitivity. Old ECM8000 used to have a sensitivity around 10 mV/Pa, so I think the value they gave me is not correct.

So, does anybody know the actual sensitivity of the new Behringer ECM8000?

Many thanks in advance for your help

Regards.

Thank you John.

I think I'll take your advice and calibrate the microphone with an SPL meter.

I'm realizing that the microphone has changed A LOT. For example, the impedance, wich before was 600 Ohms (attached file in this reply) is 200 Ohms in the new mic.

The sensitivity was before "-60 dB", and now is "70 dB".

It is really disappointing that Behringer doesn't provide clear information about such a basic characteristic of a microphone like the sensitivity.
