Tally signal voltage compatibility between Clipper3 and Tvlogic F-7h mk2 monitor

What the thread found

  • The TALLY SENSE pin on the 8-pin Lemo connector of Clipper3 outputs an unregulated 12V signal with a typical range of 11V to 16V.
  • Tvlogic F-7h mk2 monitor requires a 5V tally input signal with a tolerance of plus or minus 2 volts.
  • A voltage transducer must be installed in the tally cable to step down the 12V output from Clipper3 to the 5V input required by the Tvlogic monitor.

Depends on

  • The voltage specification for Clipper3 was not confirmed by direct equipment testing but based on user recollection.
  • No specific transducer model or wiring diagram was provided in the discussion.
