Just double-checked my Voyager manual. Interesting find in as much as =
the keyboard model uses unbalanced connections, but the RME (rack) =
version has a switch to flip the outputs between unbalanced and =
balanced.

Best wishes.

Very very few synths have balanced outputs.  Memorymoog and Polymoog are =
the only two Moog synths I can think of.  None of the Oberheims.
JP8 had balanced XLR outputs, not many other Rolands.  Hard pressed to =
think of any Yamaha or Korg synths either.

Note that XLR jacks do NOT automatically imply balanced I/O.  Even some =
pro audio gear - like the Drawmer DS201 dual gate - do NOT have balanced =
I/O despite the XLR jacks.  With the exception of the Chroma, all the =
ARP keyboards had unbalanced outputs - even those with XLR jacks!

Moogerfooger I/O are unbalanced.

Frankly synth outputs are so hot that balanced output is not needed.
Balanced outputs are best applied with really low level devices like =
microphones and any instrument with magnetic pickups.

What you REALLY need to pay attention to is all devices having the same =
dB system.  Mixing +4dBu and (-)10dBv devices is a PITA.  I love using =
the Korg SDD-3300 digital effects with my synths, but mixing a
+4dBu synth with a (-)10dBv Korg SDD-3300 results in an input that is
so hot that a slight nudge on the input control dramatically changes the =
level, and (-)10dBv output that is too low for my +4dBu line mixer.  I'm =
about to modify the 3300 to +4dBu I/O levels.
