Audio Sets Rode NTG3B

Hello,

I have the x200 with a rode NTG3B.



My Audio Sets:

CH3 Input Source (External)

CH4 Input Source (External)

EXT MIC CH1 Ref (-60dB)

EXT MIC CH2 Ref (-60dB)

EXT CH Select (CH1)

the Knobs (ch1/ch2) is in 3rd mark close to the zero.

all switches is in manual mode


Last experience I noticed a clipping noise. because I did audio record close do louder source(big speakers) around 5-6 meters distance.


In this case louder source damage the Rode NTG3B?

What Audio Sets is recommended for weddings?.



Grateful

Re: Audio Sets Rode NTG3B

I've got my own NTG3 (before the B was added for whatever reason) and I've used it to capture the sound of a rifle being fired, just a metre or two away. The shotgun mic handled it beautifully and has continued to be fantastic ever since.

I don't think you will have any issues with it with regards to possible damage from a loud sound source. It's absolutely rock solid as far as I know.

Re: Audio Sets Rode NTG3B

The NTG3 microphone has a very hot output signal. Try setting the Ext Mic Ref level to something much higher than -60db when recording loud sounds with the Rode mic. Try -30db and see if that prevents the hot output of the NTG3 from overloading the mic input of the camera and causing distortion. You would now need to also raise the recording level of the camera, but you should now have a greater range of control with the input level before the signal gets too loud.

-60db would be used with a very insensitive mic like a handheld dynamic mic that's just being spoken into. A hot mic like the NTG3 being used close to very loud sounds would need a much less sensitive setting like -40db or -30db.

Re: Audio Sets Rode NTG3B

I havent experience with PXW-X200, and don't know what is inside it, but...

There is two sorts of audio inputs:
A) input stage before attenuator
B) input stage after attenuator

For sort "A" You may have to make external attenuator and plug your mike through it.
Otherwise you wil get clipping on loud sounds whatever settings you do into the camera.

Re: Audio Sets Rode NTG3B

Hi everyone, i'm grateful for your tips for my issue. I setting -30dB and is a lot better than -60dB (factory setting)

so.. the Rode NTG3 has Sensitivity-30.0dB re 1 Volt/Pascal (31.60mV @ 94 dB SPL) +/- 2 dB @ 1kHz

in this case the suitable setting in the EXT MIC CH1 Ref is -30dB ?



Grateful
Best regards
