Dear Quad people.
I am new to CD-4 and I bought a Grundig CD-4 demodulator. I have a SME arm, Nakamichi turntable and Ortophon MC20 super II cartridge. I have a surround system.
After spending the day making up din plugs for the Grundig, I have switched it all on and I get the green pilot light coming on when I put on a CD-4 record, which I bought recently.
There is four channels of sound - coming and going. It sounds pretty awful and I would like to know what I need to do to get this all working properly please.
The cartridge output is going straight into the Grundig CD-4 demodulator. I don't know what I should be doing from now on. The unit is opened up and I can see adjustment pots.
There is a pot for the PLL oscillator - I tried twiddling all the pots but nothing seems to improve. There is a 'left' and 'right' pots at the back.
I would be grateful for some advice please.
Thanks a lot.
Dear the Prof,
I am a lucky owner of Grundig CD-4 demodulator now.. I don't hace a user manual though and the plugs and wiring of DIN and what was deliverid with it are a mystery to me.
Could you kundly share your experience of 'making up din plugs for the Grundig'. I need two RCA from Tonearm cartridge to input into DIN of demodulator (and ground?) and 4 output RCA from DIN
Please kindly help and render good guidance
Also if you hace a copy of user manual please kindly shere
Thank you
Sergey
