keeping the stereo sound from the built-in mic

Is it possible to add the external shotgun mic and still maintain the L/R stereo from the stereo mic?

This would be ideal. To keep the stereo mic for for scene sound, and use the shotgun mic to accentuate the dialogue - having them all mixed together in camera. I guess this isn't possible is it? You'd lose the stereo effect since they split the channels.

Nope. You can only record two tracks at a time.

You can use the onboard mic for one channel, and the external mic for the other channel... but the signal from the onboard mic will be either converted to mono when it's recorded on that track, or perhaps only one of the sides of the mic will be recorded (not sure). But you won't get a stereo signal on a single track, that's impossible.

What is a good shotgun Mic to use for Stereo Audio or is Mono the way to go? I mean I have heard superb things about the ME66.
 
Re: keeping the stereo sound from the built-in mic

usially you dont use stereo for dialog , most of the stereo use is for sfx and stereo ambient, its good for doco work when you dont have time to change mikes , so you can take stereo imeges with the same setup

the at-835st is anice mike , for something better you can use figure of 8 with any existing shot gun
or neuman rsm 191 or sanken cs-5 if you have some cash to spend

_______ mean I have heard superb things about the ME66. ---------

try to hear the mikes and not the superb bulshit rumors
 
Re: keeping the stereo sound from the built-in mic

So input 1 and input 2 record to separate channels? Do you know which would be considered left and which would be considered right during playback? Would it then be possible to have a shotgun or other mic plugged into both to be mixed or left as is for stereo sound?
 
Re: keeping the stereo sound from the built-in mic

The DVX records two distinct channels. Channel 1 gets played in the headphones as "left", Channel 2 is right.

You can record a mono signal on both channels by using Channel 2 and setting both inputs to channel 2. If you want a stereo signal you'd have to plug into both channels.
 
Re: keeping the stereo sound from the built-in mic

If you record a mono signal on both channls it's not a bad idea to set one channel about 10-20 dB lower than the other with the level controls. That way if you get hit with a loud peak both channels won't clip and you can substitute the lower channel in post for that part.
 
Re: keeping the stereo sound from the built-in mic

Does that really work? I tried to do that trick with a PD-150, and ehen my actor went a little overboard with his dialogue and it clipped bad, I tried to get my lowered second channel to the rescue. Imagine my surprise when I realized the channel was also clipped, but the volume was lower! I just hope the audio circuitry on the DVX can do the trick propperly.

thats becouse you did overload the input stage , the audo flow is analog to dogital -leveling -recording .
so if you wont do it properly you have to dectise the sygnal in analog domain ,
the potinsometer is riding the digital signal not analog so even you dont see distortion ,you do distort your preamp stage .
to do it right -dgo straight to ch-1 with att on (put the input on 1+2) increase the secend chanel manually until you have
good preses level (picks -6-4) stay in auto( thats only hard limmiter) in the first channel .
the benefit you have low input -the opposit that your second channel would be full of hiss .
to do the trick proprly you have to devide ( one mike 2 cables)the level for 2 channels ,then open att on one of them .

your right, I hadn't actually tested on DVX yet. Thanks Oleg, but your previous post wasn't up when I posted.
 
Re: keeping the stereo sound from the built-in mic

with dvx the final score would be much better since it has much better analog stage -if you using very hot sygnal , its better to put attenuator befor it comes the camera and then to incrise with camera potesiometer
not all the mikes are same so it depends how much presser level the mike can handle ( spl - the hier the valiu greater the sound level you can record with that mike ), in very loud situations some mike would distroy the sygnal even befor you bring it to the camera , usially the dynamic mikes have more spl then condencers ( lets forget about 130v dpa which hold f-15 eagle engine s without distorting from very close range)
 
Re: keeping the stereo sound from the built-in mic

But Oleg, wouldn't lowering one pot on the camera prevent clipping on the lowest one if the analog input stage was NOT overloaded but the digital stage on the higher chan was? I already use an attenuator coming off the mic. thanks.
 
Re: keeping the stereo sound from the built-in mic

thats ok , if you recording the same signal that was good befor a2d , thats good to place the 2 tracks in different level , 10 db is more then enouth , of course you can open the alc on (limmiter that sits around -4.5)dbfs
maybe in the next generation camera pana would include atunaitor which go in steps of 5 db ( from- 60 to -35) for better matching different mikes.
but probably they woldnt . ,
until then you have to use atunoator barrel or cable like your self
