Some are well established and have been in common use for several years, others have appeared recently, and all are vying for recognition and market share. Interfacing different protocols can be difficult and expensive, often requiring the use of inflexible, proprietary hardware. Connecting different audio networks together, which often have differing sample rates and clock domains can be a difficult and expensive process. The DN9650 Network Bridge allows all MIDAS digital consoles and MIDAS digital I/O hardware, KLARK TEKNIK DN9696 High Resolution Audio Recorders and many other AES50 devices to connect to many different multichannel digital audio networks simply and reliably. Architect's & Engineer's Specification The Network Bridge shall provide bidirectional asynchronous sample rate conversion of up to seventy-two (72) simultaneous channels of 24-bit resolution digital audio, between a three (3) port AES50 digital audio interface and a third party network module interface in a standard 1U high 19” rack mount chassis. The Network Bridge shall have one (1) Ethernet Control Port for the purposes of remote configuration from a computer web browser interface and the updating of internal software. The Network Bridge shall have two clock domains (AES50 and Network), separated by an Asynchronous Sample Rate Converter (ASRC). The Asynchronous Sample Rate Converter shall have a Bypass option with the facility to lock the Network Clock domain to the AES50 Clock domain. The AES50 Clock domain shall support selection of clock source from either internal (on-board clock oscillator) or external (incoming clock via AES50 ports) synchronisation, Word Clock input, or Video Black Burst input which shall support incoming video synchronisation signals in PAL/ SECAM/NTSC formats in Standard Definition (SD) and High Definition (HD) resolutions. The Network Clock domain shall support clock synchronisation to incoming clock via third party network module, Word Clock Input or Video Black Burst Input which shall support incoming video synchronisation signals in PAL/ SECAM/NTSC formats in Standard Definition (SD) and High Definition (HD) resolutions, as well as optionally slaving to the AES50 clock domain if the Sample Rate Converter is bypassed. The Word Clock Output shall be capable of being derived from the AES50 Clock Domain, the Network Clock domain or the Word Clock Input. The Dual Network Bridge shall have a precision clock reference provided by a temperature-controlled crystal oscillator (TCXO) with 1 part-per-million (1 ppm) stability. The Network Bridge shall have user-selectable functions for both the AES50 and Network Clock domains to stop an output clock if the corresponding input clock fails, to propagate network failures across the ASRC for the purposes of automatic or manual redundancy switchover. The Network Bridge shall support data format word length truncation and dithering on data received via the AES50 ports and transmitted via the third party network module interface. The Network Bridge shall be capable of operating from a 100 to 240V ±10%, 50 to 60Hz AC power source. The Network Bridge shall be the KLARK TEKNIK DN9650 and no alternative option is available.
