Sujet UA 6176 : Est-ce la solution ?

Citation : Et si je prenais un LA-610 MKII + carte son pro,

Citation :
La véritable modif semble être un véritable bypass du compresseur.
Sinon les autres différences ne semblent pas significatives.

Citation : This starts with the original 2-610 based on the 610 console built by Bill Putnam Sr. This pre tended to roll off slightly at the top end.
When we created the 6176 channelstrip, the 610 preamp was slightly updated to get a more flat frequency response.
When it came time to update the 2-610 pre to the 2-610S--we did a few things:
1. We added a -15db pad switch (a common request)
2. We changed the faceplate to accommodate the switch and made it visually match the silver look of our other gear
3. We also updated the circuit to have a flatter response, just like the 610 side of the 6176.

The end result for 2-610 owners, is that the original sounded a bit darker than the new one.
They are actually very easily matched with the shelving EQ found in the pre-amp.
To make a 2-610 sound like the new 2-610S or 6176 you simply boosted +1.5db @10k
To get your new 2-610S sound just like your original, you simply roll-off -1.5db @10k

Now, the LA-610 was always a bit different so a direct comparison was never really applicable.
The LA-610 had an extra 12AX7 in the input section of the pre-amp, and signal always went through the comp section--bypass would simply disengage the compression.

With the LA-610 mkII, we redesigned the circuit and now it offers a "true bypass".
What this means, is that the signal no longer always goes through the comp section when bypassed.
The LA-610 mkII also does not have the extra 12AX7 in the input stage like the LA-610.
Because of both these things, the mkII's 610 side is now just like the current 2-610S and the 6176's preamp side.

To recap:
2-610S, 6176, LA-610 mkII ---all the same preamp sonically
2-610 original--slightly darker
LA-610 slightly different than all due to extra tube and the extra gain-staging variables that creates.
