Urgent help needed! Autopan Issues

[csharp35]

Hi,

I'm working on a project that I used the Autopan plugin -whipolash on one of the tracks. When I play the mix in the studio or car its sounds fine...when I take it to the church and play it on the sound system...the part with autopan is cutting in and out. Can anyone tell me what could be wrong? At first I thought it was the cables from the CD player...so i bought new chords to go stereo into the system and the same thing happened. I even ran the ipod through the system and the same thing happened. Can anyone help quick...I need to have this done by friday!

You need to tell us what the playback system is in order to understand the problem... are you running into a mixer or straight into a sound system? Could there be a phase or polarity problem somewhere??

I'm playing the track through a cd player whose outputs are going into a yamaha mixer left and right. then of course the mixer outs are going into a power amp to the speakers.

when i use the ipod...i go straight into the mixer....i hope i answered the question right...let me know if you need more info. if there is a phase or polarity problem..i wouldnt know or know how to fix it. Any help is appreciated.

also...when i mixed the track...i did a bounce to audio to get the stereo track. i bounced it down as a wav file.

sounds like you might be using a mono cable?

Hmm... well if the autopan is cutting in and out, might this indicate that somehow only one of the left or right channels is making it to the power amp? patch one cable at a time from your CD or ipod to confirm if they are both working.... can't think of what else to suggest

okay...i'll try again. the cd player has rca outs...so i use the rca to 1/4 inch mono cables (one for the left and one for the right). I also tried using the rca to stereo (balanced) 1/4 cable and got the same result. I'll also try another CD player...and see if that's the culprit.

thanks...i'll let you know what happens.

Your clues are all right there...
Since the iPod does it too, it points to the Church system being miswired or just wired in mono at some point in their signal chain. Could be a reversed polarity somewhere even downstream as far as speaker wiring but I bet it's wired or miswired to mono at some point - maybe when it hits the power amps (which can be stereo but bridged to mono for instance). Just a guess based on what you've said.

Some of these systems appear to be stereo, i.e. stereo mixer, etc, but then they Y it to mono or just drop a channel to mono later in the signal chain which would cause what you are experiencing. I'd suggest plugging in left and right one a time to see what that tells you. Also double-check your panning at the mixer on the channels you're using (if that's applicable here).

Afterthought: you could also make a quick test mix panning everything left then everything right to see how the system reacts.

Thanks Phil...

I will check it out...i think you are exactly right. Our system at church is pretty crappy and not professionally installed. I'll try to get an experienced sound person to come with me.

Thanks again to everyone.
