Digital vs. Analog Audio
Digital vs. Analog Audio
 What does “Digital” mean?
Audio Messages are transmitted digitally over the
Audio Riser
Distortion resistant
Unlimited distribution without signal degradation
Multiplexed single circuit operation
Multiple audio channels with output control

Digital vs. Analog Audio
 Analog Source
Analog low-level audio output
 Analog Audio is vulnerable to distortion in:
Recording
Signal processing
Line Loss
External Noise induced on cables
Amplifier and transformer non-linearity

Features
True Digital for Unparalleled Clarity
 From message storage to amplifier, everything is digital
to eliminate distortion
 Up to 32 Digital Audio Amplifiers can be connected to a
DVC center
 Each DAA is configurable as a primary or backup
amplifier
 DAA is a powerful 50 Watts in either 25 Volt or 70 Volt
versions with four outputs per amplifier.

13
Large Number of Audio Zones
 Larger applications can be accommodated with additional
DVC centers
 Each networked DVC adds support for another 32 DAA
series amplifiers
 Applications requiring hundreds of zones can be created
by networking additional DVC centers over
NOTI•FIRE•NET™
Leaders in Life. Safety. Technology.
14
Network for Survivability and Scalability
 Multiple DVC centers can be networked together with
seamless integration into NOTI•FIRE•NET
 NOTI•FIRE•NET with DVC provides:
 Added survivability and scalability
 Multiple command center support
 System expansion
Leaders in Life. Safety. Technology.
15
Paging Over the Fire Alarm Network
 Every DVC has an interface with NOTI•FIRE•NET
 One channel audio over NOTI•FIRE•NET allows for
network-wide live paging
 Allows one DVC center to page over the whole system
when multiple DVC centers are networked.
