DBC Network Bridge

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.
