Ok friends, I just bought a Sennheiser wireless EW112PG2 lav mic system for interviewing people both indoors and out. Being a noob, I did get the 620-680 or whatever it was frequency range which seems to be the safe range not about to be problematic.

This receiver will be hooked up to a Sony HDR-FX1 which does not have an XLR input.

Never having used anything but the onboard mic before, how would you all recommend monitoring the audio while I am shooting interviews? This needs to be easily done in the field with minimal gear, as it has to be able to be packed on airline checked bags along with a zillion other pounds of crap.

Always use headphones when using the Sennheiser's. I have 2 sets, and they are great....but wireless devices are often subject to interference, you will want to know as it happens if it happens, so you can correct things as much as possible on the spot.

It can be a real bummer to shoot a good interview only to capture the footage an hour later and discover there are ststic bursts all thoughout it.

If you cannot use good headphones, then use ear buds, something--so you can hear it while recording.

Hello Dave,

Get a pair of Sony MDR7506 or Audio Technica ATH-M50 headphones and plug them into your camera headphone jack.

Thumbs up on the Sony MDR7506 phones, which we bought for our XHA1 kits. I use them in the edit suite, but found them a little bulky to carry and use on the run, so I parked mine i the edit bay and bought ---forgive me, I will be shamed for using amateur stuff -- a pair of Sony MDR V150 phones for about $20 at Best Buy --- they are much more compact in the bag, fit nicely around my neck when they're not on my ears, sound just fine and are, well, expendable and replaceable should something happen to them. News is not easy on gear...my two cents /Battle Vaughan/ miamiherald.com video team

I am taking notes on all said here......

Yup, Ty is right. Just plug the headphones into the top of the camera - the trick with the Sony FX1 is that the headphone VOL is under the the flip up LCD - so you'll want to turn it up. If it's still low google for a product called a "Boostaroo."

Inside the Sennheiser package is the 1/8" to 1/8" cable for connecting the receiver to the camera.

Adjust the "AF Out" on the receiver to -10,

Adjust the Tuner's "Sensitivity" to -20 or -10 and watch the Tuners VU's to see if you're hot.

Adjust the FX1's audio levels in the rear to "Manual" and start at about "3" - check the VU meters on the camera - should be just right.

This vid will help Sennheiser Wireless Tutorial on Vimeo (http://vimeo.com/2280395)

If you haven't got the headphones yet, I'd suggest a pair of Sennheiser HD280 Pro's - I prefer them over the 7506's. They cost the same $99 Sennheiser PRO Studio monitor headphones at DVcreators.net (http://www.dvcreators.net/sennheiser-hd280pro-studio-monitor-headphones/)

And monitoring at the camera at head phone jacks on camera, even if you are using a mixer before, is best way of knowing what is actually going on tape.

Guy, I found that video before on setting up the Sennheiser's and thought it was awesome. I also use DVKitchen from DVCreators, that is awesome too.

Thanks for the play by play.

Cool. You wouldn't happen to have been the Dave Allen that shot the footage of me and "the camera incident" The Mars Volta, live video from Sasquatch 2008 on Vimeo (http://vimeo.com/1077097) ???

No, I am the underwater guy...

I went a head and splurged and ordered the Sony MDR7506 headphones.

I love my SONY MDR7506's. I am sure there are others as good but I find mine comfortable to wear and uncolored to my ears. I think you will be happy.

On another point, set up the FX-1 to input the mic to BOTH channels. Then using the on camera volume controls set one channel slightly louder or "hotter" than the other. If you had a mixer with a reference tone output you could set this rather precisely, and set one channel about 8db hotter.... but without just bump it up a little using whatever sound you can use to do that.

The benefit is that if your louder ("hotter") channel never gets to clipping/distortion levels you can use it in the final mix with better results. If it does, you can use the other one. Built in safety net.

Off topic.. but if you like your 7506 HPs you'll like them even more with the Garfield Softie covers.

Chris I don't believe that you have the ability to independently adjust L/R inputs separately on the FX1. You can on the Z1, but not the FX1 line and both L/R are joined.

Michael.... thanks. I have the Z-1 and mistakenly assumed you had that same split capability on the FX-1. Thanks for setting me straight!

Go ahead and make me regret I didn't get the Z1, lol.

That is ok, as I plan on getting a Scarlet to "overcompensate" ;)

Ok, I followed the tutorial to the letter with a sensitivity of -10.

Within the Sony menu, I go to Men>audio mix>push sel/push exec.scroll down to mix/line in sel/push exec.yellow "ext mic is highlighted yellow, then I push sel/push exec one last time, then switch right side power switch to camera.

I plug in my Sony MDR 7506 headphones to the Mic/line port on the FX1 lower right.

Just prior to plugging in the Sennheiser EW100 G2 jack into the Mic/Line input, I sure hear the onboard Sony mics coming through loud and clear. As soon as the wireless transmitter jack is plugging into the mic/line jack, the headphones go silent.

Now when I take the Sennhesier lavalier mic and put it right up to my mouth and talk loud, the levels on the lower right of the fold outviewfinder show the L channel as going up about 1/4th of the total. I can barely hear anything in the headphones. If I turn the audio level knurled wheel on the camera back to 10 on manual setting I can hear it a little better, but there is hissing static in the headphones, and now the L channel sound meter will go halfway halfway on the scale.

I do have the volume all the way up on the FX1 button under the fold out monitor.

Ok, considering the mic will not be right at ones mouth, what do I need to do to get some volume out of all this? Shall I try a -20 on sensitivity? I want to use this in noisy backgrounds for interviews.

Level -24 on AF out on the transmitter with -20 db on the receiver does not change anything as an update.
