Question System Connectors

[Alfi76]

Hello Guys

Ive fot a Denon DRA-F101 and Denon CDC-F101. I bought them seconf hand without a remote control and decided to buy one which seems to have been programmed specifically for this system.
However all I can do is to turn the amplifier on/off, turn volume up/down, control the radio and that's it. No button will control the cd player. I am aware that the two units need to be connected via a connector cable which i have but not sure if its the right kind. Could you please tell me if there is a specific type of connector cable i need to use?
Many thanks.

From the pictures I saw, it looks like the 'system control' sockets are the 3.5mm type, which would either take 2- pole, or 3-pole plugs.
If you can't get to see a user manual, perhaps get in touch with Denon to find out.
(Personally, I can never understand how or why user manuals get separated from products).

Thanks for your replay Gray. Can you tell me if a three pole connector would actually carry the control inputs from the tuner to the cd player? therefore i can control the first but not the latter?

I had this little system about 15 years ago and was very happy with it at the time. Can’t remember what the remote was like honestly but I think there were two system connector inputs on each device….1 and 2….make sure you have them connected to the same one? 🤞

Sorry I can't say - that's precisely what the manual will help you with - unless Tinman above can remember what's what from his days with the units.
If I were in your position and could find no online info.....I'd open the units up and have a look at the socket wiring (or more likely their connection to a circuit board). From that you should be able to see how many poles the plugs will need.

Or you could just take a chance with a 3-pole lead in sockets 1 to 1 or 2 to 2. You're unlikely to do any harm.
You may already have this type of lead:

(You won't want that actual one as it's 5 metres long).

Does 'poles' mean whether it'll work with a mono cable or needs a stereo one? If so, most cabling that sends these 'trigger' signals is mono.

So do you think it is a mono cable then. I have downloaded the manuals for both units by the way but it does not mention about the type of cabe it is. It just says sytem connectr cable.

According to a thread on avforums.com it is:-
The connector cable is a normal 3.5mm TRS stereo cable

Just to be clear. something like this?

Yes, that is a 3.5mm trs cable.

Yes, TRS = Tip, ring and sleeve (the 3 separate poles)
A mono (2-pole) plug has just a tip and sleeve.

The lead you've pictured would actually work perfectly well even if Denon had used mono 2-pole jacks for the connection (in which case there would just be an unused pole on the plugs and an unused conductor core in the cable).
But you couldn't use a 2 pole plug in a 3 pole socket as the sleeve would be shorting out 2 poles that need to remain separate!

I wonder if a mono would be cheaper? Easier to manufacture, but probably lower demand!

Latest update. Just received that very cable bought from Amazon. It works a treat! Now I have full control of the system. Thanks everybody for your help! It was much appreciated!
