NewTek TalkShow VS-100 - Manual (Page 59)

Many different source types are
supported. The options you see can here
depend on the Input Connection selected
at left in the Video group.
For example, when the Video source is an
SDI feed, the Connection menu in the
Audio group allows you to choose between
SDI Embedded (channels 1 and 2), or SDI
Embedded 3, 4.
In effect, this flexibility lets two TalkShow
units share a common Return a/v feed over
SDI from upstream studio equipment,
while permitting each to return a unique
audio mix to its respective remote caller
(see the box, “What’s a Mix-Minus”).
The same option (to choose Return sound
from channels 1 and 2, or 3 and 4) is
provided when you employ Net Input
audio from a NewTek live production
system featuring network a/v output.
Hint: A single network connecting TalkShow to both a NewTek system and the Internet can
actually handle all Return and Call audio and video data transfer, without any need for additional
a/v cabling.
TalkShow’s fully integrated support for Dante™, the popular networking protocol from
Audinate®, provides a particularly powerful network audio solution for TalkShow’s
Return audio. Many different unique mix-minuses or other sources can be set up using
the Dante control software to target individual TalkShow devices on the network.
Afterward, all you need to do is select Dante DVS Receive in the Connection menu on
TalkShow and you’re ready to go.
What’s a Mix-Minus?
Specialized audio sub-mixes in which one
or more sources are deliberately
subtracted from the main program are
often referred to as a ‘mix-minus’.
Mix-minus capabilities can be invaluable
for productions like ‘call-in’ shows. The
remote caller needs to be able to hear
the interviewer; but if he is forced to
endure a late-arriving echo of his own
voice this would be confusing and
undesirable.
A mix minus setup can supply a clean
output consisting of just the
interviewer’s voice (or the interviewer
plus other program participants),
without sound from the individual
remote caller.
