steroe - mono problen A/V recording

[rayzray]

i transfered this from another forum here; i am baffled over this phinominon; like what happened.?

(( i thought it was unusual that Cher would have such a "Bad" DVD; so i listened to the original; WOW; what happened? it was pretty good ; and ; in stereo.!

my remake was not so good and in mono.

then i remembered this happen a while back on a Rush project.

i recorded one song; once with wireing as is; then i took the "Y" cable off the "monitor out" of my Sima SFX-9 A/V mixer, and voila; stereo.

now WHY did this happen? oh, i had a "Y" adapter there cause the monitor TV i use to monitor the projects is mono; so i "Y'd" id at the mixer.

i don't understand;

What exactly is your question?

What exactly is your question?

my question is: why is the DVD i am making/ copying from any sourse that is stereo; turning into mono; when i ttake the stereo out of the monitor out of the A/V mixer with a "Y" adaptor.?

so thake thei sanerio: SP)

1. sending a music video into my DVD program via the A/V Mixer

2. taking audio from monitor out of A/V Miser to a MONO tv; so i "Y" the stereo out on the mixer to the mono in of the TV/Monitor

3. the resulting dvd/burn is mono

i take "y" adaptor out and just run the "white/left" audio into the mono tv/monitor and the resulting dvd/burned is stereo.

what does the monitor out have to do with the audio recorded into the Main mix?

Well, assuming that the Y adapter is either:

a. in the chain before the point where you hook up your recorder, or

b. in the chain beside the point where you hook up the recorder,

then basically you're combining the stereo signal into mono before it hits the recorder.

While the cabling may be set up in a way that makes things appear separate, any "crossing of wires" in the chain [without a buffer of some sort, i.e. buffering preamp as many AV switchers use] means that that combining of signals is propagated in parallel throughout the entire chain.

I hope that makes sense, because I find it difficult to explain something that I find completely self-explanatory. That is assuming that either a. or b. is the case.

And please, don't take that as an insult to you. After all, I'm the one having difficulty putting it into words.

i kinda understand your explination; but just was wondering how the "Monitor/audio out" fits in; like i assumeed ot was separate from the main audio.

using your explimation; it means the monitor out is "in" the chain of audio events.

the "Y" cable i added is added to the monitor out;; and not at the bebinning of the audio chain.

i only use the monitor audio to losten to the final audio mix of video "A" and video "B".. assuming i am NOT adding an "aux" audio or a "mic" audio in there too.

anyways; it's all solved; i just don't know why.

tonight i made a music video for one of my grandchildren;; one of 13; and we took one song out of "High School Musical" and did two takes;

one lipsynking to "Bop to the Top" and

the other live singing the the same song.

the movie is in mono now; cause i make a copy of it while the "Y" cable was still connectin in there to the Monitor out..

no big think; i am not sending it out to MTV yet; or "American Idol"; lol.

i don't think i could handle another 10 years of being a Star; after 43 years of it; i've had it.

It appears that everything in your chain is simply connected in parallel [passive], rather than buffered in any way [active]. This is unusual; usually a/v switchers, even those in TV sets, are buffered at every input and separate outputs are buffered on their way out as well to prevent scenarios like this from happening.

I once had 2 Monster brand Y's and both of them out of the blue had only 1 leg of the Y would pass a signal. Never did figure out what caused it. Was you using the same Y both times, could it may be faulty?

Dex Otaku could it (refering to only the left signal being split) simply be causing a short(at the monitor or the recording source) of some type?POE

[rayzray]

gee;; i never thought of a faulty "Y" adaptor; and me in the music business for over 40 years; i am embarrassed that i didn't even think of that!

that "Y" cable is an oldy; one of those old Grey ones.

after i finish my Rush A/V Project, i will try CHANGING to "Y" Cable.

thanks guys for helping me; music has been my whole life; both professionally and personally.

well another thing has come out of this: as i was checking the wires; i fonally to to squese my body UNDER the two PC's and to the back of PC#2 and found that my audio out of PC#2 had become disconnected; (or i think my piano students put it in the srong whole); but NOW i have an "Out" feed to my main "Rack" and "Patch Bays". i can do my editing in "Real Time" Full Volume!!!!
