> Why is playing through a PA considered acoustic?


In 'Hi-Fi' terms, a, so called, 'guitar' amp alters the signal, as
well as amplifying it. A PA (theoreticaly) just amplifies the signal,
without any colouration of the sound.
How true this is, depends on the quality and set up of the PA. It is
similar to the Hi-Fi world in that the ultimate audiophile's dream amp,
is one with a straight path through the amp, providing no way of
interfering with the signal. However, in practice this is totaly
impossible and some distortion of the signal (colouration of the sound)
will always occur when you are trying to boost the amplitude of the
signal so, technicaly a PA is not acoustic.
But unless you've got some kind of super hearing, for live music at
least, it dosn't make the slightest difference (hence everyone plugged in
their guitars etc on unplugged).
