2 Welcome
At the heart of a Digital B Chain system, the
Crown® DBC Network Bridge allows you to
distribute multiple channels of digital audio
over standard fast Ethernet hardware and
cabling for use in traditional, e-cinema and d-
cinema applications.
The DBC Bridge accepts standard analog and/
or AES digital audio and CobraNet® digital
channels from other Cinema processors
(Dolby®, DTS®), Cinema Servers, or Alterna-
tive Content Media Players; and bridges
(routes) them to a Crown DBC network. Figure
2.1 is a sample application drawing.
This network is Crown’s proprietary “Single-
Click” solution that provides system control,
monitoring, diagnostics, and digital audio
transport. The DBC network (fed by the DBC
Network Bridge) distributes the digital audio
and system-wide control protocol to Crown
amplifiers. The DBC Network Bridge also pro-
vides the necessary system equalization, which
is stored and recalled via a series of presets for
use in both feature film and alternative content
programming.
