No audio when laying to tape

[Richard Cullen]

this is the third project I’ve tried. It happened on new project that hadn’t been laid to tape before so we thought we might have some issue with the audio file used, but the 3 projects I’ve tested have all successfully gone to tape before. I’m the only person who uses this machine and the deck so nothing should have been changed. I blame the cleaner.

I won’t cop to how many times in my career, a frustrating problem turned out to be something like accidentally hitting a record inhibit setting on a deck, or not noticing that it was in composite input instead of SDI.

I think your problem is pilot error but you have built up a perceptual blind spot as to what it is, because it is too obvious, and your impatient brain is skipping over what your eye is telling you. I know that’s often the case when I make a mistake.

Changing perspective or order of operations might help. Run your checklist of tasks out loud and physically put your finger on every button, every menu setting, say it out loud, don’t just assume it. “It’s supposed to say THIS; does it indeed say that?”

Sounds like a deck reference problem. What are the channel condition lights doing on your deck? Not familiar with the 2000 but used to have this problem all the time with a digibeta deck if the output of the deck is going back into the kona card while outputting. The condition lights on the deck would always be red when this happened and you would hear random bits of audio. Disconnect any inputs to the kona and try again.

Dave – audio mixdown doesn’t make a difference

John – channel condition light is always green. Am planning of having a spring clean of the suite at the weekend and sorting out the mess of cables under my desk so will double check all connections then.

Mark – I’ve doubled checked all project settings and made new projects and sequences from scratch, done everything I normally would do when laying to tape. I’ve gone through everything I can on the digi itself and in the Kona control panel and to my eyes everything is how it should be. Unless there is a setting that has been changed somewhere that I’ve never seen or knew about.

I just don’t see how bars & tone can go down fine perfectly every time but its the main program audio thats the problem. AJA suggested a reset of the PRAM so will give that a whirl.

Thanks for everyones help on this.

setting the PRAM hasn’t helped 🙁

The fact that you can here the audio when scrubbing or jogging through the tape indicates a deck problem. Try doing the output again with only the SDI cable going to the deck, no outputs, no reference, no monitors.

Cheers

I concur….the first thing that came to mind was it’s either the deck or the tape. Scrubbing sound means something was put down. I’m putting my money on a bad tape. Reload and try again.

3 tapes from two different boxes. will try with only the SDI going to the deck.

Something random but if nothing else has worked, why not give it a shot?

Try converting the .wav files to .mov, then re-align and edit to tape.
