Quad Help!

Thanks for that.
As far as I know, the 33 has already been modded for a cdp input. But, I will have to check this.

Actually, according to the instruction booklet, the pins connections are marked on the back of the 33 pre amp.

Ok, noob question: How do I read the diagrams in the quad 33 booklet and circuit diagrams? Where it shows the layout of the plug, is the plug facing you or facing away. So, on page 6 of the booklet there is a diagram of the connector with numbers on the pins. Is the diagram facing me - with 5 and 3 on my right, on the bottom of the diagram - or are 5 and 3 on the left?

Sounds to me like a stupid question, but I'm feeling pretty stupid right now.

Page 6 seems to show a pic of the socket as viewed looking at the back panel of the 33

If one opens up the plug (if possible, some are moulded on) the pins are usually numbered on the black plastic that they are set in.

I just looked more closely at one of the connectors. Looks like it's wired up as 1 4 2

I'll have to find out what exactly my brother in law was using. If the plugs are wired incorrectly for me, they would have been incorrect for him. I'm beginning to think he was going straight into the 405 and not using the 33...

All you have to do is take the covers of the Din plug, hold it up to the back of the 33 and see if the wires in the plug line up with the correct pins on the socket.

Pin 1 is LEFT RECORD and 4 is RIGHT RECORD

That explains your problem, as you need pins 3 and 5 (the ones on the right when looking at the rear of the plug) for playback..............................

FFS, Flashbacksales do a smashing interconnect for Naim and Quad amps, DIN - 2 Phono and don't charge a fortune for it. Order the one with standard non-locking DIN plug - pins 3 and 5 connected!

So, new leads ordered - hopefully they'll get here tomorrow.
What I got today was a lead which allowed me to connect the Denon to the 405. Stereo sound ensued! Now I'm really looking forward to connecting up the 33 to the 405 and hearing what it can do.
