    Hi

    I have a Denon 2805 which is great but the instructions (pages 5 & 22) say that optical jacks 3 and 4 can be used as output devices and connected to CD writer or MD.

    My problem is that I cannot get any signal out of these jacks. The "Digital in Assign" funtions do not seem to specify an output. Would you know how to set-up Optical 3 & 4 to output a digital signal.

    I have discovered the answer by calling Denon Customer Support. There are 2 optical OUT jacks, 3 & 4, and both of these are connected to the optical IN jacks 3 & 4 respectively. They can therefore be considered as pass-thro only. Ie the 2805 does NOT encode inputs from other sources and output them optically.

    Problem solved!

    Thanks for coming back on that one.

    The manual certainly isn't clear regarding the Optical jacks 3 & 4. Like you I read it as being optical outputs, not pass thro' of the Optical 3 & 4 inputs.

    Now I know, and in hindsight can see why they are called, optical in 3 & 4 and optical out 3 & 4, and not some other numbering sequence.

    Looking at the (same?) back panel diagram for my 3805 (in PDF form, not the printed version), if the arrangement is passthrough of the Optical 3 + 4 inputs there is no logic to showing the MD or CD recorder having its output (to OPT 4) loop through to its own Input (via OPT-4).

    Isn't it the case that although the Denon does not encode for Optical output, it will pass through any optical input to both the Optical 3 + 4 "outputs" on the Amp which will in turn allow the decks attached to 3 or 4 outputs to record digitally. In the picture in the manaual, the MD recorder will pick up any Optical source from OPT 1, 2 or 3 as they get passed through to the Opt 4 Out (and OPT 3 to be pedantic)

    I think we may be talking about the same thing here but Denon's definiton of passthrough and In/OUT may just be throwing us off course!
