Audio Down Mix Function
(See Figure 1-4.) The Audio Down Mixer function provides for the selection
of any five embedded channels serving as Left (
L
), Right (
R
), Center (
C
), Left
Surround (
Ls
), and Right Surround (
Rs
) individual signals to be multiplexed
into stereo pair Down Mix Left (
DM-L
) and Down Mix Right (
DM-R
). The
resulting stereo pair
DM-L
and
DM-R
can in turn be routed to any embedded
audio pair as desired (or de-embedded to an AES or analog audio output).

Flex Buses
For both input and output nodes before and after the internal buses, flex buses
provide flexible-structure mixer in which any of 16 summing nodes (
Flex Mix
Bus A
thru
Flex Mix Bus P
) can receive any audio input, thereby allowing
several customizable mixing schemes. Similarly, any of the 16 internal bus
signals can be applied to an output flex bus mixer. The output flex bus allows
cross-sourcing from both
Path 1
and
Path 2
embedded internal Audio Bus
sources to the Path 1 and Path 2 discrete output audio crosspoints.
Text-To-Speech
Cobalt Digital
+TTS
is a complete 21CVAA digital text-to-speech generation /
audio insertion solution for embedded and discrete audio systems.
+TTS
interfaces with industry standard Windows Share folder systems to
receive non-proprietary text, XML, or similar plain text files, and converts
and inserts realistic human-voice audio into user-configured audio channels
(typically an SAP channel pair intended for this playout).
+TTS
allows for
prioritization based on the organization's discretion (for example, severe
weather alerts out-prioritizing school closings). Alert tones are inserted over
the main program channels to alert the visually impaired that emergency
content is to occur on the SAP channel. Alerts can be played a configurable
number of times, and alerts with higher priority can interrupt current lists for
breaking news. Once the interrupt message is broadcast,
+TTS
automatically
reverts to normal audio programming. Refer to +TTS Manual Supplement
OPT-TTS-MS for detailed information and installation/setup instructions.
