Tone audio overmodulated in Edit to tape mode
When I go into Edit to Tape mode to lay off bars and tone the audio sounds way overmodulated. It sounds perfect in preview so it is not a Mackie board setting. It can’t be a feedback issue because I have black routed on the input. I could not find any settings in Edit to Tape module that would cause this. Any info would be greatly appreciated..THX
Running 10.5.6 with FCP 6.0.5 on a MAC Pro 3,1 with 8GB and a Lacie RAID mounted via ESATA.

Perhaps you are hearing both the FCP output and the playback from your deck at the same time. That could over drive the audio channel.

When I use FCP bars and tone for export to Digibeta and HDCam via my Decklink boxes I set the tone level to -20 which shows up correctly on the decks expanded level meters.
Remember FCP tone is 0db and digital requires -20 (debatable but I stand by those specs cos thats whats in my deliverables contracts!)

[Baz Leffler] “Remember FCP tone is 0db and digital requires -20”
FCP actually defaults to tone @ -12dbfs. -20dbfs is correct SMPTE broadcast spec and -18dbfs is PAL broadcast spec. Australia is the only PAL country to adopt the -20dbfs SMPTE spec.
Don’t sweat it though Baz, no-one seems to reject PAL tapes with -20dbfs tone anyway. At the end of the day, the tone reference on a digital tape is redundant but comforting to the old analog broadcasters.

Yes I agree Michael – in fact I got a QC report from OS recently stating…
“-20dBFS tone is incorrect for a tape of this standard”
I thought to myself, “what does that mean? Is the tape quality to high for a meager -20?”
Never the less, it didn’t get rejected, just a ‘mention’.
So all future HD masters I sent had -20 mentioned on the label.

YUP! But WHATEVER YOU DO…. don’t let program content exceed -10dBFS!!!
Incidently most prosumer camera’s including the Sony Z1 tend to record audio 12dB too high and I am forever setting the master FCP faders to -12.
