Couldn't come up with better title. I'm wondering about the following scenario: Chaining one Yamaha reface audio output (two 6.3mm jacks) into 3.5mm stereo input of another reface, then chaining the output of that second keyboard into the Yamaha MODX input (two 6.3mm jacks). Technically speaking is there any difference in signal levels, etc. between separate 6.3mm L/R outputs and a stereo 3.5mm input? I prefer avoiding a mixer. If such a chain would work and I can control each keyboards volume through its own slider, that would be great. Any suggestions?

The answer is yes. The 6.3mm TS or TRS jack is either pro line level +4dBu standard or even lower due to a low output implementation. The 3.5” stereo output is at headphone amp level to drive headphones. A lesser issue but still off concern is an impedance mismatch. By adjusting gains on the devices you probably can make it work. You may however experience some dynamic range compression.

Login name is a tribute to Jan Pieterszoon Sweelinck, arguably the historically first great keyboard virtuoso.
