3. Frames
Connectors
Both accept AES3-id signals at a 48kHz sample rate (3.072
MHz bit rate). The AES reference sig-
nal does not loop-through. Each input supports both balanced and unbalanced formats. Only one
connector can be used at a time for a given input.
The use of redundant references from independent reference generators increases reliability and is
the recommended method of operation. If one reference is lost, the system will automatically select
the backup reference. Supply only 48kHz reference signals to the frame.
The NV5100MC and NV5128-MC support “near-sync” operation. That is, an unlocked 48kHz
AES source can be routed by a synchronous AES input/output module pair. To accomplish this,
audio samples are discarded or repeated as required to bring the source into exact synchronization
at the output.
An AES reference is required only when there is a router in the frame and the router has AES or
analog I/O cards. The reference makes inter-mixing analog and AES audio formats easier.
S
The EM0374 generates its own AES reference if no external reference is present. The external
reference is needed only to sync the frame with your house reference.
An acceptable reference includes any AES3 formatted signal with a sample rate of 48kHz. Typi-
cally digital silence is used as a house AES reference. Miranda manufactures several AES sync
generators suitable for this task.
S
At software release 6.1.0, MCEs derive AES reference from their video reference.
Aux Bus
At the middle left portion of the rear of the frame are 2 ‘Miranda Aux Bus’ (BNC) connectors:.
If you are using an SMS7000 router control system with the master control system, connect the
SMS7000 to the Miranda aux bus connector.
The frame has two aux bus connections. The connection is loop-through: you can pass the
SMS7000 “node bus” control signals on to another device if it is required. You can connect a
redundant control system on the “node bus.”
If you are using an SMS7000 control system, terminate the “node bus” with a 50
Ω
terminator.
S
Using an SMS7000 requires an SMS7000 mezzanine card installed on each router control card.
Jumpers J4 and J6 must be set. See
Jumpers
on page 176 for detail.
S
There is no relation between this aux bus and the aux bus of an MCE or the aux buttons of cer-
tain control panels.
