Just want to share a little trick to make your Voyager sound better..
recently i had to change the OP Amps for the Headphone and main
outputs.. I changed the “cheap” one with a better and more expensive one (i can post the name of the OP amp .. if needed)
this Little change made a “HUGE difference” at least in my own ears"
I always thought that the Voyager sounded a little " how can i explain it .. Hard/edgy..
but now it got a more mellow and varm sound..
well …its a long story ..
but when i bought my Voyager and played on for a while. i noticed that when i turned up the volume to .. lets say
about 12 o’ clock.. on the headphones, it would cut the signal.. I then had to re-plug the headphones and turn the
volume down… in the beginning i thought that it had to be this way… ( so that you dont blow your ears of
But as the years went by …it began to make some strange things.. ( display would start to blink shortly.. and
that kind of stuff.. thougt i could be the software… BUT NO
And then one day the headphone output went completly silent..
and just before that ..the display was acting strange again.. Hmmmmm
I then took it to my friend, who is a very skilled tech. nerd
he then changed the Headphone jack with a much better one, and
he also changed the OP AMP for the OUTPUTS with a much better one..
AND “VUPTI” the problem was gone ..
there’es really a big change in the sound..
everything sonds much more ballanced now.. with no sharp edges..
the Only thing i had to do afterwards… was to dial thru all my presets, turn up the main volume…
and save them again..
That’s nice if your Voyager sounds now as you like. My Voyager’s in original condition, and what can I say: It doesn’t sounds great, it sounds amazing
Taste is different I think. But it’s interesting what people do to perfect their gear, I always like to read about. Thanks for sharing your modification
Yeah… this is really i nice synth …
and yes your right.. it sounded allso nice before .. when it was’nt modified..
But there’s a bit more “cream” now.. ) and i like it ))
It could be that changing the op amps for the headphone output results in an improvement in the stock sound of the phones but that shouldn’t affect the normal outs of the voyager, right?
Also it sounds like your headphone outs may not have worked correctly to begin with. It’s entirely possible that fixing the issue simply made the phones sound the way they are suppoosed to.
The op amp for the headphones is the same as for the main outputs..
The problem with the headphones output ( on my voyager) in combination with the headphones i use, was " WAY TO MUCH OUTPUT" ..
So when we changed the headphone jack.. to a better one.. we also put in a 200 Ohm resistor.. to solve that problem.
Cool! But what’s the part designation? It should be printed on the board, next to the op amp. Probably something like a “U” + a couple of digits. Like U3 or U27 or U124 etc. And was it mounted in a socket or did your friend have to de-solder the original op amp?
Oh, and there a few variations of the TL074 op amp, usually designated by additional letters, like TL074A, TL074ACN etc. Do you know which one you have?
) and i like it
