Ok thanks a lot for the insights.

Yes I did, sorry if I sounded lazy Embarassed
But still, it only contains a few pages (well at least the printed version bundled, maybe I did commit the error of not checking some PFD online) and although it explains the inputs well, there are things that are left in the blue, because obviously they just describe the features, but not really need to explain all of these questions I had, they are more of general audio knowledge.

If you connect the 3.5mm to a 1/4" TRS adapter, then on the TRS plug you have the left channel on the tip and right channel on the ring, with the sleeve being common ground. That's stereo on a single plug

Ok got it. Maybe I still needed a bit of the "inside" knowledge of contruction of these cables, because probably there is no such thing as 3.5mm to "dual" 1/4" TRS.

The simplest solution in this case is to use a bog-standard 3.5mm --> RCA cable, plug that into a stereo channel of the mixer, which by chance also has RCA inputs. You could also fit 1/4" TS adapters on the RCA plugs and plug those on a pair of TRS inputs.

When you say a pair of TRS you mean the stereo channel dual "line-ins", right?
Although re-reading the manual they don't say if those line-ins are TRS or TS in the end, but yeah, I get it as RCA should be totally fine or a couple TS jacks inside them.

you have to stop thinking that TS/TRS has anything to do with the signal. All it is, is how many wires there are in the cable (if fully wired).

Ok thanks for the explanation.

Maybe buy the cables, connectors and a soldering iron and make your own ... it will probably help your understanding. Smile

So either use the cable that thecontrolcentre mentioned to go through the stereo channel or use a 3.5mm to dual 1/4" TS and plug into channels 1 and 2 (or 3 and 4) and pan (shown as balance on the zed10fx) channel 1 all the way left and channel 2 all the way right.

EDIT - or of course into the 2nd stereo channel....

Correct

They don't state weather the two stereo line inputs are balanced or unbalanced indeed. In practice it won't matter that much anyway, since all combinations will produce sound without major issues.

As a matter of fact that sounds like a great idea... will have it in mind... Smile

Yes, but as a matter of fact I think I'll just use the same 3.5 to RCA and use a couple TS to RCA adapters (one TS that takes RCA as input) to use for the mono channels or the stereo but in the 1/4" inputs.

Hehehe I actually only came across that page last night by chance (don't know why I hadn't seen it), but anyway I was more referring to generally speaking, the construction of TS and TRS plugs, since they are not the same all the time.

Ok, I will try both combos and see what feels better.

Anyway I think I finally grasped the basic concept and at least was able to make an inventory of the cables I need last night given to your valuable help guys, thanks a lot!!!
