MB-SEQ V3 Gate/Clock output protection resistors?

[vcfool]

Hi,

I am about to put the SEQ V3 on a case. I am using an AOUT_NG and also enabled the Gates on J5.

Should I add protection resistors on the Gates outputs sockets to prevent short-circuits in case of accidentally connecting them to an analog output? I do not want to damage the PIC...

What about the DIN Sync Clock and Run outputs? I am also using one 3'5mm socket for each one.

I guess I'd be on the save side by adding the resistors, but couldn't find a mention anywhere. Something like 470Ohm or 1K would be fine?

Thanks!

470 Ohm should be fine as a short circuit protection.

Please give feedback if this is compatible with your gear once you tested this.

Best Regards, Thorsten.

For now all is working great without the protection resistors.

Some of my analog gear needs more than +5V to get triggered and I have to use a comparator or some other way to boost the gates to near +10V. I guess I could add some transistors inside the SEQ, and get the +12V from the AOUT_NG PSU.

I'll add those 470Ohm and I'll post about any issues.

Thanks!

I have installed the 470 Ohm resistors in my upgraded V4 MB-SEQ. Everything seems to work as before, so no problems adding these protection resistors.

Didn't try them on V3 but I guess it'll be just the same.

Thanks again!
