PHASE INVERT Audio Modier
When on, the PHASE INVERT button is illuminated and the right channel of the currently
selected stereo audio Source is inverted (phase shifted by 180 degrees) prior to further
processing and reproduction.
The PHASE INVERT modier will aect the loudspeaker audio, line-level audio outputs,
phase meter reading and also, by default, the main meter readings (refer to the Main
Meters section of this manual).
Being able to invert the polarity of one channel of the monitoring is very useful.
For example, sometimes being able to put the speakers deliberately out of phase is
useful to identify the presence of a phase error elsewhere in the signal chain. When trying
to match the levels of two channels, such as when aligning a stereo pair, being able to
invert one channel and then sum to mono (to produce a cancellation null) makes very
fast and easy work of an otherwise ddly process.
MIDDLE + SIDE (M+S) Audio Modier
When on, the M+S button is illuminated and the left and right channels of the currently
selected stereo audio Source are converted to/from a Middle+Side (also known as
Sum+Dierence) signal prior to further processing and reproduction. An input signal
in standard Left+Right (L+R) format will be encoded into M+S format before metering
and reproduction, while an input signal in M+S format will be decoded to L+R. The two
processes are identical.
The M+S modier will aect the loudspeaker audio, line-level audio outputs, phase meter
reading and also, by default, the main meter readings (refer to the Main Meters section of
this manual).
