UVW1800p and rec/play issue
on Jun 19, 2009 at 9:53:59 am

Hi all and sorry if its not the right forum for my question.

I have a problem with my UVW1800P SP Betacam.
When i am recording bars to tape i set the UV levels to 0.
When i playback the tape, the UV meters are 2 lines higher.
I think that it needs to be calibrated but i dont know how.

Does anyone have any ideas?

And another question, if i record to -2 lines, when i playback the UV levels are correctly to 0. Will this be correct?

Thank you.

2 minds are better than one.

Are you using Sony tapes or some other brand?

I noticed the same problem with Fuji or Maxell tapes. With Sony tapes it comes out right on the nose.

Hi Dean,
I am mainly using Maxell tapes, but the exact problem occurs to sony tapes too.

Hello
Calibration needs to be done by a technician with alignment tapes.
It is true that output can vary with different brands of tape but I suspect the answer is simpler than that.
The VU meters in a VCR monitor the output connectors.
If I recall correctly the UVW Betacam machines rise 1.5dB if the output is not terminated with 600 ohms.
Do you have anything connected to the audio output connectors?
Is it a 600 ohm load or high impedance?
At the end of the day 2dB is a barely perceptable error so I would not fret too much.
