1.1 About This Manual
This manual explains the audio menus that are available on an LV 7770 when the LV 7770
OP70 (16CH DIGITAL AUDIO ADAPTER), LV 5770SER42 (ANALOG AUDIO), or Dolby option
is installed. For details on how to operate the LV 7770, see the LV 7770 (MULTI RASTERIZER)
Instruction Manual.
1.2 About Terminology Used in this Manual
• Single Input Mode
This refers to the mode in which the SIM key is off. Press the A and B keys to switch
between measuring the signal that is being applied to SDI INPUT A and the signal that is
being applied to SDI INPUT B, respectively.
• Simul mode
This refers to the mode in which the SIM key is on. The signals that are being applied to
SDI INPUT A and SDI INPUT B are measured simultaneously.
• About the Input Format
The input formats are written in this manual as shown below.

2.1.1 Selecting the Signal to Measure
To select the signal to measure, follow the procedure below.
Procedure
AUDIO →F•1 SOURCE SELECT →F•1 INPUT SELECT: SDI / EXT DIGI / EXT ANA
Settings
SDI: The audio signal embedded in the SDI signal is measured. “EMB” is
displayed in the lower right of the screen.
EXT DIGI: The digital audio signal that is applied to a DIGITAL AUDIO IN/OUT
connector on the rear panel is measured. “AES” is displayed in the lower right
of the screen.
This option cannot be selected if GROUP A and GROUP B (OP70) under
REAR PANEL SETUP in the system settings have both been set to OUTPUT.
Simul mode is not supported. Perform this measurement with the SIM key
LED turned off.
EXT ANA: The analog audio signal that is applied to an ANALOG AUDIO connector on
the rear panel is measured. “ANA” is displayed in the lower right of the screen.
This option can be selected when an LV 5770SER42 is installed in the LV
7770 and ANALOG AUDIO under REAR PANEL SETUP in the system
settings is set to INPUT.
Simul mode is not supported. Perform this measurement with the SIM key
LED turned off.
