to be thundering about. On a less technical and more
economic level, it necessitates somewhat beefier and
more serious buffer amplifiers on each source to feed
the buses.

Ordinarily though, the mix resistors are of such a

value that, in the context of a complete mixer, the

combined effectively paralleled resistance is well below

the optimum source impedance of nearly any mix-amp
