Sound Issues with HMC151

[Mandip]

Hi,

I shot a wedding the other day and whilst reviewing the footage discovered sound problems from the 1st dance onwards. The audio was perfect throughout as I was monitoring via a headset but on playback there appears to be some crackly distorted interference that kicks in.

Basically I had the following tried and tested set up:

HMC151
Channel One set to Input 1 - connected to Senheiser EW100 via DJ XLR output
Channel Two set to Input 2 - connected to wired Rode NTG1
Both channels were peaking at -6 through the dial tweaks

Initially I thought the interference was purely on Channel One (wirless mic) but then realised the same interference was on Channel Two (rode mic). What could have caused this?

Anybody else had similar problems? Also is there anyway of cleaning up the interference? I use Adobe CS5.

Thanks.

Hi Mandip

I have experienced almost the same issues with my 151E and Sennheizer EW100 G2. From time to time I heard very high +12 db crackling noise while recording. I contacted Sennheizer and they said it could be mobilephone or other electrionic noise (radio/tv etc) because the G2 does not use diversity (only have one antenna). I ended up buying the Sennheizer EW100 G3 (costed me almost 1000$ ) wich make use of diversity (two antennas). The cracking noises I have had previously has not been an issue since. Maybee it is your problem as well? Hope you find a way out....

Good luck!

Xoomtell, thanks for your response. What you suggest may well be the cause however I am still non the wiser why during the recording i got the same interference through my wired rode mic. Could the wireless kit somehow affected the other channel on the camera.

There has not been much response on this posting so would appreciate anyone with similar experience to shed some more light. As it stands I have not used the rode/ wireless configuration since the incident out of fear of it repeating.
