I have a Rode NTG-2 mic on my Canon XHA1. I mainly film outdoors, and living in Wales, we usually have a lot of windy weather. I have the supplied foam windshield and dead cat, but was wondering if using the HPF on the mic would be better for these conditions. What exactly does this filter do.

Many thanks,

Mark.

Hey Mark Could you let us (the newbie group) know what an HPF is?

oh and also...dead cat?

Do you live on the coast of Wales or inland?

Regards, Terry.

A HPF(High Pass Filter) rolls off frequencies under a certain frequency. In the case of your Rode NTG-2 it's 80hz. It's a fairly gentle rolloff so it's not like your microphone won't pick up any 70hz material but if that's important to you then don't engage the HPF. Use your ears and if the wind is still present in the audo then try engaging the filter if everything sounds good then there is no need in loosing these frequencies for no reason.

A dead cat is a furry wind muffler, such as

Ohhh I get it...Dead cat, clever :)

Thanks Steve.


So an HPF will help filter low frequencies along with the already existing filter built into the mic?

I am asking because this may be useful to me when i'm out shooting on site. It does get quite windy, enough to blow you over sometimes. I suppose this HPF is an accessory and not something on the mic itself?

A high pass filter (also called a 'low cut' filter) can be found several places, depending on the mic. Some mics have one in the mic itself, activated by a small switch. Some modular mics have one that comes as a standard or optional accessory that is in a little module that you insert between the mic capsule and its body by removing the capsule, attaching the filter, and replacing the capsule. Some (many) mixers and some cameras have one at the mic inputs. And you can get some with XLR connectors that insert in the line between the mic and the mixer/preamp.

Thanks for all the reply's. The HPF did help in cutting the wind noise down a little.
