Chapter 2: Overview
Front and rear panels of the DN9652 Network Bridge
Since the network clock domains (A and B) contain digital audio, an intermediate asynchronous sample rate converter (ASRC) effectively resamples the audio as it
passes between them, while obeying Nyquist sampling theory1. The ASRC has a bypass option for when both domains are locked to the same sample clock; this has the facility to select one of the clock domains as a master, which allows one to be synchronously clocked from the other to minimise latency.
•AES50 clock domain Supports either internal or external synchronisation. The DN9650 uses its
•Network clock domain Supports clock synchronisation to the incoming clock via a third party network module, word clock in or video black burst (supporting PAL/NTSC formats) interfaces. Additionally (DN9650 only), the network clock domain has the option of slaving to the AES50 clock domain.
Supported third party
•LabX MADI V1.14
•Audinate Dante
•Aviom
•Ethersound
•It is intended that more third party protocols will be supported
The DN965X has an internal Linux web server running a
The units are capable of operating from a 100 to 240V ±10%, 50 to 60Hz AC power source.
Key features
The DN965X has the following key features:
•1U high, 19” rackmount unit.
•Able to interface between AES50 and third party
1.The Nyquist sampling theory defines the process of sampling audio within a digital system.
