Invert and mute
Each of the 32 audio input channels can be individually inverted or muted by selecting mute
and invert in the de-embedder invert, AES invert, de-embedder mute and AES mute menus.
Note:
When routing Dolby E, to ensure integrity of the audio any Dolby E stream must be
treated as a stereo pair and no audio processing such as mute, mono and gain is applied.
Routing matrix
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 of mixed I/O.
Note:
All routing matrix changes are live so care should be taken when re-routing as all changes
in routing will appear on the output of the routing matrix instantaneously.
Embedder pattern
The embedders can be set to give either the Sony pattern or the SMPTE pattern.
AES setup
From the STATUS top menu rotate shaft control to select the AES Setup menu. Press F1 and
then rotate the shaft control to access the AES Setup menu options. This menu is where the
AES I/O is individually configured to be either inputs or outputs.

termination
Rotate the shaft control to show the AES I/O termination control.
Press F1 and rotate the shaft control to select.
Balanced, Unbalanced.
Note:
The AES format control acts globally on all AES inputs and outputs.
AES format
TANDEM 3G has eight AES I/O, all of which can be configured independently to be either an
input or an output. It is also possible to select globally the format to be either balanced or
Unbalanced giving 110R differential and 75R single sided when termination is applied. Hi Z
will have an impedance of approximately 1k.
