Display Information
in positions ma
tching their place in a surround-sound listening environment,
and the Loudness display, where loudness targets are shown. (See page 143,
To Check Audio Phase.) (See page 146, Elements of the Surround Sound
Display.) (See page 69, Audio Loudness Session.)
Audio source/setup: Displays the selected audio input and related setup
information, such as Listening Mode when in Surround display. (See
page 141, Audio Monitoring.)
Level meter labels: Identifies the signal in each meter bar. The labels vary
according to whether the audio sources to the level meter bars are normal
channel pairs, surround channels, or Dolby sources (the Dolby source labels
include D
olby type).
Level meter ballistics readouts: Displays the selected dynamic response
charact
eristic.
Axes: Shows the orientation of the two audio signals when displaying phase;
shows t
he orientation and amplitudes of the sound fieldwhendisplaying
surround sound. (Axes are selectable for a n X-Y or Soundstage plot.)
Phase
correlation meters: Displays the phase correlation between the
two-channel bars under which it appears. The meter of the pair selected for
the Phase display also appears in the Phase display. (See page 143, To Check
Audio Phase.)
Test level and Peak program level indicators: Diamond-shaped markers
between the level bars indicate the configurable limits set up for the display.
Above the Test level, the bar displays in a y ellow color. Above the Peak
level, the bar displays in a red color. Test level is also known as Reference
le
vel or Line-up level.
Level meter scale and units: By default, the units are in dB relative to full
s
cale (dBFS) for d igital inputs and dB relative to 0.775 Volts (dBu) for analog
inputs. The 0 dB mark is digital Full scale for digital inputs and 0 dBu for
analog inputs. You may also set the 0 dB mark to either the Peak Program
level or the Test level. See also CONFIG > Digital Audio Displays > Set
Meter Type To, and CONFIG > Analog Audio Displays > Set Meter Type To.
Dolby E Guardband thermometer: Guardband limits can be set for SD,
HD, 3G, DL, and CMPST signals. A Dolby E Guardband thermometer is
displayed on the Audio display so that you can monitor whether guardband
limits are being exceeded.
NOTE. The loudness measurement supports three types of filters: Flat,
A-weighted, and RLB (ITU-R BS.1770). You can view the measurement in the
Audio Session display and configure it from the Audio pop-up menu.
