TANDEM-300 User Manual R1.2

TANDEM allows the user to also handle a wide variety of embedded audio formats when
'ALL' is selected. Some formats exceed the minimal buffer memory requirements by a
wide margin, but will still be safely de-embedded by TANDEM. The selection 'ALL' is
automatically selected by TANDEM internal logic if a SMPTE or extreme format of
embedding is detected. There may be a moment's loss of good audio if one of the SONY
modes is selected and then later the input format changes from Sony to SMPTE or an
extreme format.
The following table summarises the available choices. To enter this menu, ensure that
only MENU DIL switch 5 is down.

This function is used with AIP2, DIP2RS, and RS4 cards so that the embedded insert may
carry a channel status message to indicate if the audio source was a true stereo signal, or
two monaural signals. This message is also applied to AES outputs from the DOP2 cards
when no input is present, or no AES message available.
