PART 3: The Acadia Audio System
PHASE
Pressing the Phase button in the EQ area
of a console channel inverts the phase for
the assigned audio channel. This 180
degree shift makes positive signals negative,
and negative signals positive. The
phase switch is used to prevent signal
cancellation that occurs when two signals
are out of phase with each other.
In general, if your mix seems “weaker”
when you play a particular audio channel,
that audio is probably out of phase with
the rest of your mix—try inverting its
phase to “strengthen” it in the mix.
IMPORTANT: Within the signal flow of an
audio channel, Phase occurs before sends
(both pre and post). Phase is not available
for console channels assigned to hardware
outputs.
NOTE: You can permanently affect the
phase of an audio file with the Invert
Phase command in the DSP menu. For
details, see Chapter 31: DSP Menu in your
Audio Reference manual.
To invert the phase for an audio channel:
From the Console Window menu
choose, EQs>Gain Faders.
The EQ area is added to the audio channels
in the Console Window.
