What about when an audio connection
goes bad? You’ll be pleased to know that
each physical output destination in each and
every BLADE has the ability to automati-
cally detect silence and, if need be, switch
to an alternate source defined by you should
the silence endure for longer than a specified
period. Furthermore, it can be programmed to
automatically switch back when the audio is
restored. You can use this extensive capabil-
ity to map out multiple levels of automatic
failover to enhance your system’s reliability.
If a program output from a control room goes
away, you can switch to an alternate. If a mix-
minus feed to a remote drops out, you can feed
him a back up. If your entire network goes
down, you can have the BLADE that feeds
your air chain switch to a backup playback
machine and start it playing. Because every
output on every BLADE has this capability,
you can layer as many levels of failover as you care to.
Consult the Navigator GUI section of this manual for specific details on audio signals,
connections, salvos, mixing, and more.
There’s more that the WheatNet-IP network can do besides transport audio. It can also
transport logic changes. No modern broadcast facility can operate without logic control.
This is what lights a warning light when a studio goes On-Air, mutes a speaker when
a microphone turns on, starts a playback machine when a console button is pushed, or
starts a recording when a relay is closed. The WheatNet-IP network
transports logic change information between every BLADE, control
surface, and PC that is attached to the system, via the same CAT-5e
LAN connection and Ethernet switch used for audio. You don’t need
to add anything. Each physical BLADE has 12 general purpose logic
connections that can be individually mapped as inputs or outputs.
Each control surface has a number of automatically defined logic
functions (Start, Stop, On, etc.) for each fader, as well as a num-
ber of programmable buttons and indicators, plus an assortment
of mutes, tallies, and other functions. Between the jacks on the
BLADEs for physical connections, plus all of the virtual ones on
the control surfaces, just about any logic function you need can be
accomplished. On top of that, Wheatstone can provide dedicated
switch panels for host and talent locations, some of which contain their own scripting
language for creating complex conditional logic configurations.
