It is not necessary to use an Aux audio bus to configure a special audio ‘mix minus’ to return to the remote
Skype caller in this case. The return audio for Skype TX is handled automatically, ensuring that (except when
the
TalkBack feature is engaged) the remote caller will receive a special mix comprised of the Master mix
with the remote caller’s sound removed.
Note: These special a/v inputs are based on the professional Skype TX broadcast platform and require the use
of its dedicated control application. Alternatively, you can connect directly to NDI a/v output from a dedicated
NewTek TalkShow Skype TX unit, or the standard ‘consumer’ Skype client configured for NDI output using any
Switcher input. See Appendix B: Skype and Skype TX for more information.
SECTION 16.6
TALKBACK
The Audio Mixer input labeled TALKBACK serves a special purpose, providing a way to converse with remote
Skype callers off-air (i.e., without intruding into your live program). You can choose what audio source to
supply for
TalkBack purposes from a variety of input types, as discussed in the previous sections.
As mentioned earlier, by default the Connection option for an external Audio Mixer input assigned to a Skype
TX™ channel allows the corresponding control group to govern incoming audio from that remote Skype
caller. In this case (that is, when an aud io control is ‘listening’ to incoming audio from a Skype TX channel),
a new button labeled TALK appears beside the group’s SOLO button.
When the TALK button is lit, audio you supply via the TALKBACK input (typically a microphone connected to
one of the inp uts on the system’s backplane, or perhaps the system Stereo Mix supplying audio with sound
from a 1/8” motherboard audio input) is sent to the remote caller, temporarily replacing the normal mix -
minus sound that remote caller would otherwise hear.
At the same time, the Mixer sends incoming sound from the remote Skype caller to its Headphone output,
enabling you to have a two-way conversation off-air.
Hint: You’ll want to take steps (such as by enabling Mute, or perhaps Follow Program Video) to prevent sound
from the Skype caller being sent to your live audio mix during TalkBack conversations.
SECTION 16.7
COMMON CONTROLS
Many important features and optional settings are common to most source types, and some even appear for
outputs. Let’s review these before continuing. Audio Mixer Scroll Bar
For switcher products that have numerous audio inputs, the Audio Mixer Scroll Bar provides access to all 32
inputs with the simplicity of moving the scroll bar located below the SOLO buttons.
16.7.1 MUTE
Mute switches for inputs and outputs appear as speaker icons located just above in the main Mixer panel. A
single switch controls multiple channels, as appropriate for that source.
Enabling Mute removes the sound from that source from all downstream audio mixes and outputs.
