Lissajous Display
Select to determine the type of Lissajous display that appears in the Audio pane. There are
two types of Lissajous displays (Soundstage and X-Y). The soundstage selection displays a
lissajous, which is rotated so that the in-phase signals appear on the vertical axis and out of
phase signals appear on the horizontal axis.
X-Y displays a lissajous with the left channel mapped to the vertical axis, and the right channel
mapped to the horizontal axis.
Configure Phase Bar(s)
The phase bar monitors the instantaneous phase relationship between two audio channels. A
properly phased stereo pair produces a phase pointer (yellow mark framed in black) that
moves within the green zone, whereas a reversed channel produces a pointer that moves
within the red zone. The phase bar polarity can be set to Normal or Reverse.
Damping
The effect of higher damping in a phase meter is to show an averaged rather than a peak
value of phase. The Phase Bar Damping in the AUDIO SETUP\METER SETUP\CONFIGURE
PHASE BARS\DAMPING can be set to FAST, 1 to 10, or SLOW.
AES Validity Bit
The AES Validity Bit is used to detect PCM (pulse code modulation) audio or non-PCM audio.
Non-PCM audio can include Dolby or digital data.
Output Preferences
The Output Preferences is used to determine what level is output from the audio option.
Analog Output Level
The output audio level can be adjusted from -50 dB to +6 dB for analog and digital inputs
independently.
The default output level for a -20 dBFS digital input produces a +4 dBm analog output level
(600
Ω ). For example, when applying a gain adjustment of +6 dB to the output with a -20 dBFS
input signal, the audio output level will be +10 dBm into a 6 00Ω termination . The Audio
Output Level adjustment default is 0 dB.
Display Setup
The Display Setup menu is used to configure the Display colors, graticule, monitor, and time
code.
