Das STUDER und ReVox Forum

Hi,

I have a defective module ANT Telcom C4 DM, so would be interesting to repair it.
Yes, I saw common user manual for E100-200-300, but It does not have a schematic for the compander modules itself.
Maybe somebody here can help? Or any other service manual would be appreciated.

I plan to use it in Dolby frame (as C4DM cards compatible) with my Revox B77 and Studer A807.

thanks.

Sorry, I can't write in German as I am from San Francisco, California. But I can read with google translate.

I have all Manuals / Schematics.

Send me your Mail-Adress per Privat-Mail (PN) and Manuals are coming.

(California needs Telcom, not Dolby?)

Best Regards from good old Germany,

Rudy

I am curious to try. C4 some kind of different, so want to compare.

Thanks, Good Samaritans provided for the C4E and C4DM schematic.
I plan to put C4E in SPICE simulator to better understand how it works in details.

Suddenly in the C4E card, which easies to read and test, the page with VCA schema is missed. It should be about 10 transistor VCA, 4-76.11b or so.

Does anybody have it?
