764 Digital Audio Monitor User Manual
MUTE
Location: In-bar.
The MUTE indicator flashes when the digital audio data on the
input channel remains at zero-value for n or more consecutive
samples. The factory default value of n is ten (10); it may be
changed through the Level Meters submenu. A setting of zero (0)
disables this indicator.
The MUTE indicator persists for the “CLIP/MUTE Hold Time,” set
through the Level Meters submenu. When a Session is running, the
instrument counts MUTEs and displays the current total on the
Session display.
No Reference Signal
Location: Audio View, below the Session or Phase display.
The 764 is not locked to an incoming signal on the REFERENCE
input. Likely causes of this message include: missing reference
signal; incorrect “Reference Input” setting in the Inputs submenu; or
an inadequate or defective DAR signal.
The flag will persist until a valid reference signal is detected, or
until “Suppress Sync Loss Flags” is selected through the Level
Meters submenu.
No Video Input (Option 01 only)
Location: Audio View, below the Session or Phase display.
Video input is selected, but there is no video signal present at the
input. The in-bar INPUT UNLOCKED flag also appears in all four
level meter bars whenever this message is displayed.
The flag persists until a valid digital video signal is detected at the
SER. VIDEO IN connector, or until another input is selected.
