DVX100 - Using Audio "Input 1"

It seems that you can't have the "input 1" audio record to "channel 2" while filming - in which I currently have a Panasonic MC200 mic plugged into. Does that mean any audio source coming in from "input 1" is basically recorded in mono ONLY to "channel 1" and has to be duplicated over to the right channel in post-production to simulate stereo audio?

If that's the case, could someone shed some light onto why audio "input 1" can only be recorded onto the (left) channel 1 audio and why someone would use this option instead of just using input 2 where you can record simultaniously to channel 1 (left) and 2 (right)? Do people just use "input 1" as the main (ideal) audio and then use a secondary audio input to record onto channel 2 for a backup (or soft) audio track? It's all a little confusing to me.

I just started using the DVX for filming so the audio options are very different from what I'm use to... just trying to figure it all out.. the right way...
Any advice or info would be highly appreciated.

Thank you!!
 
I'm no audio expert but aren't mics mono anyway? so recording on two tracks is basically just duplication of the mono track?
 
Yep, you're right which is why people will copy the audio input to both channels during recording to simulate stero. I'm use to equipment that always allows this but the DVX doesnt allow it for input 1. I'm assuming people use devices through input 1 for a MAIN audio track and then use a second softer source for channel two as a backup track in case the audio spikes or something goes south on channel 1... I just wanted to be sure that was the case and that there wasn;t somehting I was missing that was special about the DVX.
 
Do people usually shoot with only one main audio track and then copy it to the other in post production? If so, it's news to me. I'm use to recording with simulated stereo DURING filming. that's why the input 1 setup on the DVX seems strange to me.
 
there is no need to copy the track in post. Each audio track in your NLE is set to go to the left and right by default. All you are doing is creating an identical copy that goes to the left and right again when you copy it to another track.

The only time you would need to use two tracks is when you record with two mics in a stereo set up or use a true stereo mic. Then you would pan the channels left and right to create a stereo mix.

I do record the same audio track on both channels, but it isn't for stereo. I record one at a lower volume than the other incase there is overmodulation on the main track. If the main track is good then I delete the second track out of the NLE.
 
In the setup menu turn on ALC (thats your mic alignment) then plug your mic's XLR into the number 2 jack. From there you'll get the same mic feed to channel's one and two, and you can create a different level of audio for each channel, so that one's set to record higher volumes, while the other will pick up the lower volumes, and you'll be able to avoid any peaking...

In post you'll have a "stero" audio configuration...Lower levels on the right channel and higher levels on the left...

Good Luck!
 
ALC is not mic alignment. It is a limiter that keeps the audio levels from going too hot. It works pretty good, but does not catch all the peaking.

There is a switch on the inside of the LCD that will allow you to push audio from input 2 to channel 1 along with the normal channel 2.

Again I say each track in your NLE is already going to the left and the right. Tracks in NLE's arent speaker specific. For example track one doesn't go left only while track two goes right only. How do track 3 through 99 work? They are all left and right unless you go into the audio mixer and pan them to left only or right only.

There is no need to record two identical audio tracks onto two channels. The only purpose of sending one audio input to two channels is to have one set at normal level and one set at lower level to have a backup incae there is a peak.

If you are going to record stereo then you need to hook up two mics that are setup in a stereo pattern or hook up a stereo mic into your two inputs. Record your video. Then you would use track one and two in your NLE to build the stereo track. You would pan the mic that was on the left to hard left and the mic on the right to hard right in the audio mixer.

Unless you are recording in true stereo there is NO need to copy your audio tracks in your NLE you are wasting time. The tracks are already being sent to a stereo mix.

It isn't that hard.
