  UVW1800p and rec/play issue

  Posted by Yiannis Valkan on June 19, 2009 at 9:53 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.
