The audio controls also include individual VU meters, Gain knobs, and an AGC (Automatic Gain Control)
option. These allow you to modulate audio for the streams separately from your primary audio outputs.
Hint: Streaming output is always de-interlaced.
Streaming Output involves more options, too, since there are so many different ways to stream. In this panel,
you simply configure the audio and video sources sent to the streaming output. All other options and settings
relevant to streaming are discussed in Chapter 18.
F AILSAFE
FIGURE 91
NewTek’s multi -tiered ‘Always on Air’ hardware and software failsafe systems provide confidence that, short
of a complete power failure, the show will go on. Video passthrough ensures that as long there is power,
audio and video from hardware Input 4 is routed to
Output 1 in case of a catastrophic software condition. If
at all possible, streaming output and recording also continue even if all else fails.
In some studio settings, however, more elaborate hardware failsafe systems may be in use. Typically, such
systems take over broadcast duties whenever the output signal fails. In this sort of pipeline, the native
failsafe video passthrough mechanism can actually
prevent the external system from engaging.
For this reason, a Failsafe control group has been added to the Output tab. This lets you disable the A/V
passthrough when necessary. (Note that A/V passthrough is off by default and must be deliberately enabled
to function.)
Hint: Only use fail-safe when a stable video source is connected to video Input 4.
