The LCR thing was an early invention. They only had a switch. They did not figure out the pan pot concept until a bit later. Modern panning is a better thing
(in terms of the console) than straight LCR switching. Remember LCR was the first attempt at output routing. Doesn't mean we have to stick to it either.
They would have not used stereo in the way
Bat suggest early in the piece. That requires two channels and the consoles of the day had very few channels and they would have not wasted one by doing that technique. I also doubt they would have routed a single mono channel to two mixer channels and set one to Hard L or Hard R and the other the Centre and played with balances that way either.
Also altering the level on a stereo signal the way
Bat suggests is not the same as having a stereo signal being returned to two channels
(which we can afford today) and being able to pan those returns anywhere as I have outlined in post #30. What is good about that is the levels of both sides of the stereo image remain constant. If you start altering the levels on one side of a stereo image it will go askew.
It is a bit like the old analog vs digital argument. Analog came first and most believe it is the best, nothing better, have to sound like that at all costs. But it can be noisy, add distortion, alter transients, wow and flutter etc..
(all really great stuff!) What we have now is very good and mostly superior so jump in, use the latest technology and go with it. The good thing like digital recording sounding very analog when it wants to, is that the modern pan pot can do both LCR and everything in between. You have got both options now. You would be a fool to not explore the possibilities of what fine static panning can also offer and also movement too. That is an important one.
Danny thanks for that link you were right it sounds great and the smooth panning at the start sounds great on my system too.
