Author Topic: Cat222 & Cat280T: Urgent questions! Patrick A. Meister Film Handler Posts: 22 From: Switzerland Registered: Aug 2003 posted 07-25-2004 02:34 PM                     Hello 1) I just built a small Dolby A Encoding Facility with a Cat222 Dual A-Type Card. There is one question: How is this card triggered? There are 3 connectors for NR On, Record/Play and Dolby Tone On. How many Volts do they need? +15V, -15V or +0V? 2) Well, I'd like to know, why there are 3 LED's on the Cat280 SR Card with Tape, Ref, Dolby Noise marked? What are they for and why doesnt this SR Card produce a DolbyTone when plugged in CP50 and the link for it is set? Is there a possibility to re-solder the cards to studio-cards? (encoding possible) Kind Regards Patrick  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 07-25-2004 03:23 PM                     "hy doesnt this SR Card produce a DolbyTone" Because to distinguish between A type and SR mags dolby uses Dolby Noise as a level ref for SR rather than Dolby Tone which is used for A type  |  IP: Logged Patrick A.

Cuz I can't hear any sound when I connect the two "Tone-Connectors" used to kick out the A-Tone with the Cat22s in my CP50. Well...when the RefTone is a Noise on SR, how to measure...? With this REF LED??? How does this work? Is it possible to resolder the Cards to studiocards? now they are fixed into Decoding...  |  IP: Logged
