bear with me please because I think I may be overthinking this LOL!!
I have a studer CD player that runs on 115V or 230V, currently set at 115v.
I have a wired studer remote that runs on 200v - 240V
Can I plug the player into 120V as per normal and simply buy a stepup transformer to power the remote, then connect the interconnect cable from the remote to the player without any harm being done to the player? 😱

Did the remote come with the CD player? Surely the remote works on a low DC voltage.
Does the remote actually have its own power port?

Yes the remote is a genuine studer D739, an option for broadcasting operations... remote is wired to the player via parallel port cable and has its own IEC jack, 200v - 240v operation.
CDP is a D731 115v/230v (set to 115v)

Perhaps inside the remote there is a jumper for switching voltage or if it is SMPS based the PSU could work on 120V, but should be stated on the specs label. Try to find a schematic manual.
If it were me I would try it with a step-up transformer.

Found a picture of it, bunch of DB connectors on the back. You're most probably OK, DB connectors are only rated for 100V, so there can't be mains on a pin, can't see Studer doing something that stupid.
You would need to isolate the power pair wiring from the CD supply but I think its feasible current would be low so I don't think a big transformer is required.
1993 and it still sells for £1000 -nearly £2000 (UK) .

I welcome dissenting opinion, but I can't imagine a problem if the step-up transformer has isolation to the secondary.
To be extra conservative/cautious, you could power the remote without connecting interface cables and check for excessive leakage currents between the two chassis before committing to interconnection.

like I was saying I'm probably waaaayyyy over thinking this, it has to work with a single stepup on the remote.... that parallel connector can't have any AC voltages on it that would be crazy! @leadbelly LOL! thanks fellas I'm gonna do it!!
I found this in the player manual

It looks like an ordinary 9 volt secondary isolating transformer feeding a 5 volt regulator.
The types I normally see in UK have two 115V primaries that can be wired in series or parallel for operation on 115/230V.
There is a resin plug in the middle with a couple of threaded inserts for the fixing screws.
Just measure the two wires going into the board to confirm the voltage and buy a new transformer locally. There appears to be a 1 amp bridge rectifier next to the board header so you could use a smaller transformer. It looks a bit over rated.
It will be a lot cheaper than a step up unit and will save desk space.

Refugee1, googling around I see numerous replacements available (I didn't know they were so readily available, I really should go this route thanks) I'd still need to power it up at 230v so I could measure the secondaries 🙁 and I'd like to use her ASAP lol 🙂

It has a 10 VA transformer inside. You may be able find a suitable 120V replacement if you can figure out what the secondary voltages are. its a pretty small transformer.
