 View Full Version : Wireless mic with GH2 
 Jim Snow April 15th, 2011, 09:00 PMHas anyone used a wireless mic with a GH2?  I just hooked up mine and the peak level goes into the red on the monitor in the GH2.  The output level of my wireless receiver is not too high.  I even set the level in the camera to zero in the menu with no change.  It is just fine on my EX1R.  Am I missing something?  The manual has nothing to say about this.

 Jim Forrest April 15th, 2011, 10:21 PMHey Jim...completely off topic (I would have PM'd you but I can't find a way on this forum)
 I was looking for an earlier post of yours on downconverting HD to SD for DVD authoring.
 I use Edius 6 and can export to uncompressed AVI.  I have been using Procoder 3 but I am still getting some jaggies.
 What is your process again?

 Jim Snow April 15th, 2011, 10:36 PMJim, One of the easiest ways to do this is to use TMPEGEnc.  Just render out to Canopus HQ and then open in TMPEGEnc and resize.  Procoder is a great encoder so you may want to just resize in TMPEGEnc and then render your MPEG with Procoder.
 Jeff Harper April 15th, 2011, 10:39 PMJim, I've used the Sony with good results, can't understand your issue, sounds very problematic, wish I had a solution.
 Kevin McRoberts April 15th, 2011, 11:16 PMI've been using a Sennheiser EV100 G2 system.  On the camera side, it's as low as it goes.  On the receiver side, I adjust AF OUT to about -24 to -30 to get good levels.  That same receiver setting on my Z1U or HVX  is far too low (typically use -12).  Must simply be a lot of internal pre-amp going on.
 In testing, I've noticed that the level meters in the camera hit the first red mark right around -6, and the second around -2... as tested by droning into the mic until that level was just barely reached (super scientific n all).

 Yeah I am using TMPGEGEnc 5 now and still not too happy.  What size did you resize?  I was impressed with what you did with the cat video.
 Seems that getting HD to look good in SD on a DVD is quest for most of us.  Maybe I should start a new thread for this since this is about wireless.
 Jim Snow April 16th, 2011, 07:50 AMJim, I suspect the jaggies you are referring to are interlace artifacts.  HD link which is part Cineform NEO HD does a great job of deinterlacing._

 Thanks Kevin, I suspected that.  I will try your suggestion later today.  I can't find any information about the audio recording in the GH2.  Does anyone know where I can find more info?
 Oren Arieli April 18th, 2011, 11:54 AMIf you don't get satisfactory results lowering the receiver output, a quick/cheap/dirty method is to purchase an in-line headphone volume attenuator (Radio Shack sells these on the cheap). They are 1/8" stereo input/output...so I'm not sure if it's compatible with the GH2.
 Jim Snow April 18th, 2011, 12:01 PMThanks, -30db out of the wireless receiver did the trick.   I think I will pick up a couple of the Radio Shack Attenuators.  It would be nice to keep the wireless receiver to the -12db setting that I use on my other cameras.
