It is not necessary to use an Aux audio bus to configure a special audio ‘mix minus’ to return t o 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 so und 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 Skyp e 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 audio 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 inputs 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 Vi deo) 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 thes e before continuing.
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.
Hint: Muted sources still show signal activity on the VU meters, but levels are drawn in gray rather than full
color. This is also true for sources with Follow set that are not currently audible on output.
One important exception to Mute op eration involves recording. The IsoCorder™ feature lets you capture any
MIX a/v output - i.e., the primary output or outputs (varies by model), or directly from hardware audio and
video inputs with matching numbers. That is, the audio recorded with the video is taken from the audio input
