assuming that there is a stage of bussing happening before the master buss? If this is the case, what does this do sonically (if anything)?
it's more a Geekslutz forum - Gearslutz.com
believe is nice, but it not necesary when there is good ears.
yes, there is summing whitin the summing...
old consoles have summing in groups of 8~16, to the 2mix bus, in hope to keep crosstalk lower & also lower noise floor.
summing is done "passive", and the more channels summed, need more compensation gain at the output, too much gain sometimes gives more noise if not designed properly.
is beleived that mixing 8+8+8+8=2 is better than 1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1=2
there was a test somewhere in GS, with a Summing box, 16 digital channels, mixed in pairs to 8ch analog, vs. 16ch. Analog.
with Apoge da16x
it all depends on the summing box desing.
a bad 8+8=2 is not the same as a good
Folcom, is pretty transparent.
in the case of a Mackie 16.8 buss console...
but i dont know if the 1+1 stage has more groups, like some vintage consoles.
schematics can tell.
a test could be done with 3x folcrom...
mixing 16channels with 1x folcrom or 1x dangerous 2 bus lt vs.
mixing with 2x folcrom or 2x dangerous, @ 8channels each, and those 2+2 mixed with another folcrom or dangerous = 2.
all 3x must be same brand/model.
in theory 3x should be even more... Good or Bad
if summing is designed to be transparent, more summing should give more transparency.
if summing is designed to be X colored, more summing should give more X color.
and if summing was designed to be noisy, more summing should give more noise.
very interesting to do with 7x good summing boxes @ 4ch each.
some consoles like MCI JH-600, have different circuit design in the control room vs. the 2-track tape Out.
