Re: ESD protection for HiZ inputs?


 

I use BAV199 for 'common' amps and 1n4004GP for stuff which might see P48V.? My guess is this is OK up to 10M.? But Jules is the authority here ... as THAT & Wayne are for P48.
?
I wouldn't use Schottkys for anything LN
?
The guys to listen to are those who have had experience.

More like 10 years or so. But the board has been exchanged by MOTU, a
few years ago.
I would be grateful if you can open up your Traveler Mk3 and have a look.
?
MOTU, Oz, tell me nearly every Mk2 had to have its PCB swapped.? And ALL the replacements had Schottkys replaced ... alas by more Schottkys ... which will also go noisy.
?
You can easily see evidence if this has been done to your unit as the diodes are large.
?
Shame as the Traveler(s) had SOTA portable preamp performance ... if it wasn't for this problem and the shonky software/drivers.? New MOTUs don't have quite the same level of LN performance.
