I didn't see in his post anything about line outs.

They're at the top left of page.. was it 66? The wires seem to be labeled C to C4, but the "C" part is actually a graphic indicating a connection. Anyway, they come out of the big box on the top left (the CD player, IIRC), go up, then go to the right.

All these posts are nonsense. Upon suspecting where the line outs might be, one should measure voltages and resistance to ground on all four terminals. If they are safe, then a test telephone in MONITOR mode will tell you if there's audio present.

Of course, you have to have the unit in front of you to do this, but after all our posts and advice you have to do exactly that anyway, with the unit in front of you. So just do it! See if those four terminals have audio on them! (A later page even shows a stereo RCA cable coming off a board near the top of the unit.)
A good answer is easier with a clear question giving the make and model of everything.

Couldn't you just connect the speaker terminal outputs to a High-Low level convertor and then wire that to your DA system?

Sure, this would work -- assuming that there is no ground loop.

While not the end of the world, there is a constant noise voltage associated with the output of a power amplifier. Of course, this noise will be attenuated, along with the signal, because the High-Low converter will attenuate signal and amplifier noise, but the noise floor of the system will be elevated somewhat.

Ideally one would want to ship the phono preamp output to the main system.

I haven't read through the documentation for this unit, but in situations such as this it has been my custom to locate the phono preamp output and attach my own jacks or a direct connection. Even without documentation, especially on older equipment, this is relatively easy.

Edit: I just scanned the manual. This is a CD changer. Therefore my comment about "Phono Preamp" does not apply in this case. In my mind "jukebox" is a vintage device and equates with records.

Further Edit: The last page of the manual indicates that a stereo feed is available for external amplifiers. I don't know if this output is controlled by the unit's own Volume control.

Another Edit: Look on page 26 of the PDF file. There is a DIN socket for RECORD OUT on "CENTRALE-CD".

Ship? Move it to the other room? No, you want the phono preamp as close as possible to the phono cartridge.

But I thought he was just talking about using the CD portion of this thing.

Oh. I see you've discovered that. But isn't there a phono section, too?

The music vending operators in my area use Audionics PAS audio activated line level switch part # 95-0784-00.Available from suzohapp.com. Around a 100 bucks.

Mmmm, okay....
I find no description of what this thing does or why it might be needed.

If I understand correctly, OP wants to know how to get analog audio out of a jukebox so he can feed it to a multiroom system. The small amount of information I can find on the PAS switch makes it look like something that handles an existing analog audio signal. For instance, if you have background music playing, maybe this item will switch from that source to the jukebox when it detects audio coming from the jukebox. That doesn't help locate or extract the audio signal itself, though.

I suspect this item doesn't meet his needs.
