User’s Guide
If you have different references (e.g., NTSC and PAL), or
dual
references, switches can take place
according to one or the other reference.
You can specify, in MRC, whether your video reference connection is redundant or dual.
(See the
Miranda Router Configurator User’s Guide.
)
Switch points use references based on priority, as follows:
Making Reference Connections
AES reference connections require a stable audio signal source set at 48
kHz. Video reference
connections require a stable source of PAL, NTSC, or tri-level sync. The control card uses these
references to perform takes at the proper point in time (according to SMPTE RP168).
Making AES reference Connections
1 Locate the AES reference connections on the rear of the router, as shown in Figure 2-22. AES
reference connections are labeled
AES REF 1
and
AES REF 2
.

2 Connect
AES REF 1
, using a 75
W
BNC cable, to a stable 48
kHz audio source.
3 For redundancy, also connect
AES REF 2
to a stable 48
kHz audio source.
