6000E vs 4000E Sonics

[BN1studio]

The big difference I remember - hopefully correctly - is that the 6000 has a stereo bus compressor and the 4000 is quad. This means you can use the back busses on a 4000 to pump the compressor but you can't on the 6000

Hi

I owned both , the 4000E modules sound the best.. The 6k sound good, but not as good as a 4k module.. The 6K mix section to my ears is not a sweet. But still has nice punch and mojo.. But with digital I think you need the console as clean as possible..

Hi

With the 6000 you have 3 x stereo buses feeding the stereo master bus. Each channel strip output can be switched to either one of these buses, giving you 3 parallel "master buses", A, B and C. The 8000 gives you 2 x A,B,C,D (and the 9000 picks up on this legacy).

The 4000 is only Quad bus.

Regarding the 6000 modules I don't understand why they don't sound as good as the 4000, if they are virtually the same. The difference is in the summing structure of the center section, which in the 6000 has the 6000 mixer for A,B,C before and then uses different opamps to sum everything, as far as I know.

Actually I know that Norman Druce did some customization on 6000's, where the A,B,C buses have now different flavors, such has A = traditional SSL, B = Neve, C = API. Which is pretty awesome!

Hope to have been of help.

Cheers,
