PAM1-3G8 Version 7
2.2 Main Menu
The example below shows PAM1-3G8 in normal dual screen Metering Mode listening to
the LtRt Downmix from a decoded Dolby Digital audio bitstream.
Press the
Encoder to access Main Menu. The encoder is then used to highlight and
select from the displayed Menu options. From any Menu , pressing Hotkey 1 (illuminated
red) will exit the current menu page.
The Main Menu screen also displays information about the current selected input signal as
shown in the photo above.
2.2.1 Dolby E Timing and Rate Information
From software version X06 , the top level menu of the PAM1-3G8 shows extended
information about any Dolby E sources . This shows the frame rate of the Dolby E
information and its timing relative to a video source where available.
For AES inputs, the frame rate information is displayed as a minimum, eg:
Dolby E 20bit 29.97 - or - Dolby E 16bit 25Hz
For embedded Dolby E sources, the start line position is displayed, eg:
Dolby E 16bit L11
This functionality is also extended to mixed sources. If an AES source is selected for
monitoring, whilst a video source is selected with the same frame rate, then the display will
give the approximate line position of the AES
Dolby E start relative to the video. This
allows the timing of an AES signal to be checked either before embedding or after
extraction (note the embedder / extractor delays need to be accounted for in a system).
For sources of different frame rates, the display reverts to the
Dolby E frame rate. The
video frame rate is already displayed on the top level menu.
Dolby Digital sources are also identified, although no further information is provided
without a decoder.
All of the above functions are available both with and without on-board
Dolb y decoding,
providing the source has a correctly formatted SMPTE 337M header
