Audio input problems

How can I connect my camera to the audio output of a DJ’s mixing deck without the sound distorting beyond recognition.
On recent trials it worked for speech but not music, is this where audio attenuators come in?
Or am I barking up the wrong tree?

We have tried this with three different cameras & two different mixing decks, each time we used the ‘audio out – recorder’ sockets on the mixing decks.

Any advice would be gratefully recived

You could run it straight into the mic socket
but you must make sure that you are feeding a mic level signal into the camera,i suspect that you have been trying to feed a Line level signal in which would give you horrible distortion.A lot of mixers do not give out a Mic level signal so you may have to get something to convert it.
The other problem is do you have manual audio
level setting on the camera or are they all Auto Gain Controlled,as this could lead to a rise in hiss at quiet moments.
Just re read your post and the recording out sockets u used are Line level.

The sound quality is likely to be very poor if you are trying to use the mic socket.

Have you tried recording on MiniDisc and importing the sound to your PC as a .wav file, assuming of course you are working on a PC with Premiere or an equivalent. I find this can produce results within around half a frame accuracy - and for quite long periods.

Regards,

Paul

This was my problem a couple of posts ago (under Microphone situations) speech was OK until I raised the mic and belted it out. Luckily my audio was usable after a few tweeks. I now learn – despite my great age and wisdom – that the LINE OUT is not the correct thing to use.
So therefore – as Mad_Mardy suggests, one needs something to convert the signal from Line Out to Mic IN. Is such a gimmick available? Answers would help many I feel.

The only one off hand that springs to mind
is the beachtek XLR converter which bolts on underneath your cam and has two XLR inputs
one for left and one for right,these will except mic or line level inputs.
trouble is they cost about £200
i have one and am well chuffed with it.

Thanks for the responses; is the input into a minidisk recorder not the same as the mic into a camcorder?
I will soon be in the market for an upgrade but £200.00 on a Beachtek XLR converter would mean me not upgrading to a ‘Raptor RT’ at this stage I think that the raptor is coming out favourite. What I will do is include a Beachtek XLR converter to my longer term shopping list.

my minidisc has both a mic level input and a line level input , so they are not both the same as a mic input to a camcorder

Sorry to come here late, but I've only just started looking into this section.

Coming out of a mixer at line level into a camera at mic. level will cause all sorts of problems.

On the other hand, reducing the mixer output level to mic. level has its own set of problems by increasing noise - ie: you are amplifying, padding down, then amplifying again, noise increases and quality drops.

Best is always to go in at line level (assuming the camera has line level audio inputs).

Audio to MiniDisc (or better, DAT) is an excellent idea – MiniDisc recorders normally have both line and mic. inputs and the line input is normally of higher quality. High quality microphone pre-amplifiers are not cheap and cameras and consumer MiniDisc recorders often compromise here – so line level is definitely best.

Another advantage is that you can often go directly to the computer in a digital format and avoid a DA/AD conversion.

As long as you can sync up and do not drift – no problem.

Hope this helps.

Update time
I have purchased a Sony minidisk Walkman. I have since tested it using line in from a DJ’s deck, we then used the Walkman as the player to belt out to an unsuspecting audience, the only notable difference was a slightly lower audio level which is easily compensated for.
Thanks to everyone

Just take care with the Sony MD.

If you do not press “end search” before recording you could erase a previous track (at least earlier models did this) and you have to press “pause” to change recording levels and cannot do it on the fly.

Otherwise an excellent machine.
