• Two two-channel bar graphs (for a total of four channels) with two Lissajous and
two Phase bars
• Three two-channel bar graphs (for a total of six channels) with three Phase bars or
CineSound 5.1 with two Phase bars
• Four two-channel bar graphs (for a total of eight channels) with four Phase bars or
CineSound 5.1+AUX, 6.1, or 7.1 with up to three phase bars.
Lissajous can be selected as Soundstage or X-Y displays.
Input assignments, scaling, input levels, and response can also be modified using the
Audio Setup menu. The function of the audio is dependent upon the audio option
installed.

Audio Scales

The Vertical audio graticule scales change according to the scale selections made in the
AUDIO SETUP > METER SETUP > ANALOG or DIGITAL SCALE menu and the
format being displayed.
The Scales are:
• TYPE I
• Type IIA
• Type IIB
• Type I + 8
• Nordic
• DIN 45406
• dBFS (Digital only)
• Zero dB Ref dBFS (ref –20 dBFS) (Digital only)
• Custom dBFS (Digital only)
• Custom dB

Vertical Audio Displays

The Vertical Meter displays the level, reference, and ballistics detail in a vertical
format. There are eight analog audio input channels (four stereo pairs), eight AES/EBU
digital input channels (eight stereo pairs), and 16 embedded audio channels
(serial-digital video input only) available for selection in the menu. A maximum of
eight channels display simultaneously. Audio input pairs can be assigned to any meter
on the display.
The displayed inputs can also be monitored as analog signals on the 37-pin, D-Sub,
ANALOG IN/OUT connector. The displayed AES/EBU or embedded audio will be
converted to analog audio for the monitoring output. The output audio level can be
adjusted from -50 dB to +6 dB around the reference-input level. The default output
level for a -20 dBFS input produces a +4 dBm analog output level (600Ω). 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 600Ω termination. This
