NR (which channel)?

say i want to record sound on my pd150: channel 1- on board mic, channel 2 - wireless mic. do i leave the Noise Reduction ON so that the onboard mic doesn't pick up noise? or do i switch it off so that the channel recording the wireless mic doesn't record that strange metalic buzz which accurs when recording with a remote mic while NR is on?

sort of urgent. going to shoot with the above setup in about an hour.

thanks

You cannot remove the buzz so turn it off.

In a reasonably noisy environment, any noise generated by the camera is masked by the environmental sound. I leave mine off and never have a problem unless the surrounging environment is very quiet.

I've forgotten the switch is there.

thanks. i actually had it on. didn't get your reply in time. but tested before the wedding began and sound seemed fine during playback, so thats how i left it.

when shooting a documentary about 3 months ago, i was actually directing and not operating the camera, the camera guy had noise reduction ON. sound was recorded with a boom microphone, connected to the pd150 through a mixer. footage of interviews clearly had a slight metalic buzz which would appear when the talker was talking and would fade away a fraction of a second after the speaker stopped.

turned noise reduction OFF and the problem was gone.

but i thought that when using a mic mounted on the camera as primary source of sound, it is better to turn noise recuction ON.

I've modified my PD150 with a CAC-12 microphone mount so maybe that and the more directional microphone from my DSR-300 makes a difference. But I don't get much, if any camera noise from my setup and if I did, it would normally be masked by the environmental noise I encounter in most shoots.

I can only remember hearing the zoom motor noise once in the year + I've owned PD150's. Even when the drum bearings wore out, the sound didn't reach the audio unless I folded the microphone right down next to the tape door.

What exactly does this noise reduction do? I would guess that it's simply a noise gate. If no one knows, I'll run some experiments and report.

Please test. I turned mine off and will never turn it on again so I haven't played with it.
