Audio Down Mix Function
(See Figure 1-5.) 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).

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
is
available as a software option for new BBG-1022-FS units. For field upgrade,
the unit must be returned to the factory for option installation.
+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.
This supplement is furnished with the option.
Audio Events Detect Function
Option
+QC
provides a
Audio Detect Events
user interface and an
Event
Triggers
user interface for checking user-selected channels to detect audio
silence conditions. The
Event Triggers
user interface in turn allows instructing
the device as to the action to take upon an event (such as go to a changed
signal routing, activate a GPO, send an automated email, or go to a
user-defined preset).
