Rode Ntg3

Just doing a bit of shotgun troubleshooting here:

 

If you A/B the NTG-3 with the 416, what's the difference in gain?

 

I did a little test of my own and found the NTG3 to be about 9.7 dB hotter than the 416. I expected them to be a lot closer in sensitivity.

 

Normal?

@Rick Reineke  how did you calculate the sensitivity difference?

I also did the math and I got a 2dB difference in sensitivity.

NTG3: 31.60mV/Pa = -30dB re 1 VPa

MKH416: 25mV/Pa = -32dB re 1 VPa

 

-30dB re 1 VPa - (-32dB re 1 VPa) = 2dB diffrence in sensitivity between the two mics according to manufacturers specs

 

@Adam White how did you test the sensitivity difference?

@JayKay I recorded the same source simultaneously into Pro Tools using an Arturia Audiofuse, set at the same level, and used the gain plugin to measure the difference in the recorded file. Not super scientific and I'm probably not testing "sensitivity" at all. Just wanted to measure the difference in output and it's pretty significant.

 

I guess I'll need another NTG3 to see if there's anything wrong with mine. Or another 416!

Sorry, I did read that wrong... So yes, the difference between the two mics is about 6,5mV which in this case comes out to be 2dB.

But 9,7dB difference sounds a bit excessive.

 

@Adam White You have to be 100% sure that the gain of both channels are set to an equal amount for your test to work.

You could do the following test to check if your system is setup properly:

 

Record the same audio (e.g. short music track) with the same mic but first on channel one and then on channel two with the gain set to an equal amount on both channels.

Both recorded tracks should then have the same amplitude.

So, your gain plugin should then measure zero difference between the two recorded tracks.

If that's not the case then there is something wrong with your test setup.
