10 General Operational Notes The ADX-2400 is designed to provide delay, level control and distribution for eff ects or commentary audio. The system can be used for stand-alone delay of 24 AES audio ch.
11 The Ethernet Part The Ethernet transmission uses the Cirrus Audio 'Cobranet' system, which is an industry standard. It is a professional, highly-reliabl e system which packs audio data into 'bundles' of 8 channels. The bundles are given numbers from 1 to 999.
12 Setting Bundle Numbers The 24 transmit and 24 receive audio channels in the ADX are divi ded into 8- channel groups. These groups are assigned to network channels or 'bundles'. There are six bundles per ADX unit, three for receive and three f or t ransmit.
13 Exceedi ng this bandwidth limit will cause dropouts in the audio, and in severe cases may cause other problems such as sync and control problems. An Ethernet switch, which g enerally forms the hub of a network, can partition the traffic so that bundles only go the receivers which are listening to them.
14 Cobranet 'Discovery ' PC A pplication Cirrus Logic, the developers of Cobranet, make available on their website a nice PC application called 'Cobranet Discovery', or 'Disco'. It can be downloaded and installed on any PC running W indows XP.
