Audio delay
Audio delay can be assigned, or not, to each individual stereo pair by checking the tick-
boxes adjacent to each pair. Audio present for each audio pair is given by a simulated
LED. A useful feature is the total delay which is given in milliseconds, the total delay
being the sum of the fixed frame delay plus the variable PCM audio delay.

Audio delay
Each de-embedder and AES input stereo pair has a set of controls to enable the various delays.
These controls in combination with the video delay controls (0, 1, 2 frames) can be used to
delay the audio with respect to the video and compensate for any small delay between the
incoming video and audio signals, or when bypassed, delay the video with respect to the audio
by up to several video lines. The selectable delays are; Frame delay giving a fixed 1 or 2 lines
of delay, User delay which selects the global -20 to 80ms delay. Note, a negative delay is only
possible when a frame delay has been selected i.e. 1or 2 frames -20ms to +80ms.
Routing
At the heart of TANDEM 3G is the twin 32 input/16 output routing matrix. This will
allow any of the up to 32 possible inputs, 16 embedded channels and up to eight stereo
AES audio inputs to be routed to any of the 16 outputs for embedding or up to eight stereo
AES outputs. The AES channels can be configured as either inputs or outputs from the
AES SETUP menu giving a total of eight stereo channels in total of mixed I/O.
