5.4.1 Balanced / Unbalanced Input connection
When linking the same source signal to several input channels,
be aware that there is a limit to the number of channels an
output source can “drive”. A typical output source (e.g. a DSP
crossover unit) can drive up to 4 amplier channels before
line-drivers would be required to buffer the signal.
