Line out of a Deck to a radio transmitter?

Hi Everyone,

Forgive my lack of knowledge on this one!! I'm After a bit of advice from someone in the know. I have a shoot coming up of a live music performance on a stage. two cameras and a go pro. Fairly simple to shoot but am just a bit concerned about the audio as i haven't shot much live music before.

I haven't had a chance to speak to the people organising the gig yet but i have been told all the audio will be sent to a deck with a line out.

I have a Sennheiser G3 wireless lapel and about 15m of XLR cable. Ideally i would like to plug the wireless transmitter into the deck and receive to one camera and sync the other cameras in post.

My question is:

Is it actually possible to come from the deck to a wireless transmitter through a line output? If it is possible, what adapters do i need to get from XLR to 3.5mm as far as balanced and un-balanced audio goes? During the Olympics i had a nightmare in the sort of adapter/line & mic area and i don't want to feel like that ever again!

It would be easier to just hard wire from the sound deck straight into the camera but as i will be roaming around it could get tricky.

As a last resort i could hard wire to the wide camera at the back, but that will likely be a long way from the deck.

Would you do it any other way?

Thanks in advance

Paul
 
Micing and mixing for PA audio and micing for recording are very different. In a live sound gig, "all the audio" may very well NOT include instruments such as the drum kit or guitar cabinets that are loud enough that they do not require further amplification. These instruments will be missing from your recording except where they bleed into the vocal mics. Second, you need to know the specifics of the output from the sound desk - is it XLR or TRS, balanced or unbalanced - and WHICH "line level", studio +4dBu or consumer -10dBv?

The Sennheiser bodypack transmitters will accept line level but you need to use a special cable with the TRS end going into the transmitter wired with signal hot on ring, signal ground on sleeve, and tip jumpered to sleeve. This is NOT the standard wiring for an off-the-shelf XLR -> 3.5mm TRS, !/4 TRS -> 3.5mm TRS, or phono pin jsck -> 3.5mm TRS cable or adapter. Sennheiser makes a purpose built cable or you'll need to wire your own. It is NOT the XLRM -> 3.5mm TRS #CL-100 cable included in the microphone kit - that one is specifically for the receiver's output to an XLR input - some people try to use that with an XLR gender changer or XLRF->1/4TRS adapter in use it to feed the transmitter but it won't work properly for line level signals.
 
Hi Steve,

Thanks so much for the detailed reply. so do you think that if i get the proper cable from sennheiser to allow a line input into the transmitter i SHOULD be ok? is the cable you are talking about this one...

Now the other problem is that i am in Sydney and the gig is on Friday.... Anyone know where to get one? Videoguys are out of stock and i went to Videocraft yesterday and they didn't have one...
 
You would probably hugely simplify things by recording the audio off-camera using either a computer with a firewire/usb audio interface like an Apogee Duet or a Tascam DR100mkii or any other recorder that handles line level. Just a thought...

Yes, that's the correct cable. Wired XLR pin 2 to TRS ring
