Baldwin Funster Posted May 11, 2020 Share Posted May 11, 2020 This seems to be recommended on the 76 but not the 61. Anybody have issues using or not using the choke on the usb cable? I will undoubtedly lose track of this thing when I want to do an update or something. Quote FunMachine. Link to comment Share on other sites More sharing options...
EVC Posted May 11, 2020 Share Posted May 11, 2020 If you mean the ferrite bead placed around the cable, from the functional point of view, it must make no difference. The ferrite is a measure mostly to reduce common mode RF emission/conduction through the cable (and we are talking mV tenths of mV levels here), and it must not affect the USB differential signals. One point for the cable with the bead is that it most likely is of better quality than the one without. Quote Link to comment Share on other sites More sharing options...
Baldwin Funster Posted May 11, 2020 Author Share Posted May 11, 2020 The snap on ferrite core is included in the manual bag . In the manual it says the user MUST ( my emphasis) use the ferrite core . Then says ds76 only. Seems odd. Quote FunMachine. Link to comment Share on other sites More sharing options...

KuruPrionz Posted May 12, 2020 Share Posted May 12, 2020 If you do not use the ferrite core, everything will burst into flames and there will be a smoldering crater left to remind people. So leave the ferrite core off and give the cable to one of your enemies! Quote It took a chunk of my life to get here and I am still not sure where "here" is.

Baldwin Funster Posted May 12, 2020 Author Share Posted May 12, 2020 Wow. That ferrite core must be made from interstellar moon rocks. I'm sure glad I got me one. And it apparently strangles weasels. Quote FunMachine. Link to comment Share on other sites More sharing options...
OB Dave Posted May 12, 2020 Share Posted May 12, 2020 Apparently the 61 passed EMI emissions testing and the 76 didn"t. Ferrite core was the cheap and easy fix, I"m not familiar with these keyboards but apparently the internal circuit cards are different for something. Do the 71 and 76 have different control panels or something? Quote Link to comment Share on other sites More sharing options...

Do the 71 and 76 have different control panels or something? No it's the exact same controls and features except in a longer chassis. The 76 is newer and came out some year or 2 after the 61 and 88. Maybe they forgot a piece of shielding? Roland seems to be known for including this snap on ferrite piece. I searched roland ferrite and got several results. I just wondered if anybody successfully ignored the issue. Quote FunMachine. Link to comment Share on other sites More sharing options...
timwat Posted May 12, 2020 Share Posted May 12, 2020 For six generations, the Nord lead has come without the need for a ferrite choke, and life was pleasant. Now, Roland requires a ferrite choke and look what happens. We have murder hornets. You do the math. Quote .. Link to comment Share on other sites More sharing options...
