Grenoble, France/Barcelona, Spain (June 10, 2005)–Digigram, a leader in PC audio interfaces and innovative networked audio devices, revealed at the AES convention in Barcelona its EtherSound-based product plan for a 5.1 or 7.1 multichannel radio automation infrastructure.
By tripling or even quadrupling the number of discrete audio signals, multichannel broadcasting seriously challenges traditional installation schemes built on analog or AES/EBU cabling and the resulting one-connector-per-mono/stereo-signal paradigm. Digigram’s network-centric approach, which uses EtherSound technology and standard Ethernet components to distribute the audio, will help broadcasters and their suppliers cut costs on cabling and rack space, and at the same time increase the routing flexibility.
As digital on-air-console manufacturers have started launching multichannel-ready consoles, Digigram will use EtherSound technology to suggest a simpler and more cost-effective way to link these consoles to the rest of the broadcasting infrastructure, especially to the radio automation servers. Through the end of the year, Digigram will launch a number of different PCI sound cards with high channel-count EtherSound connectivity and EtherSound audio bridges with AES/EBU I/Os that are shaped similarly to the existing ES8in and ES8out models, thus connecting the server’s hard disks directly to the EtherSound network.
Digigram will extend its PCX and VX sound cards ranges with EtherSound-enabled models, which will inherit the embedded processing power of these sound cards and offer traditional analog and AES/EBU I/Os. Additionally, Digigram will launch a new range of linear sound cards that will be limited to EtherSound connectivity only but offer a higher channel count than the PCX and VX models.
Fully compliant with IEEE 802.3, EtherSound networks provide transmission of up to 64 channels per cable in 24-bit PCM audio at 44.1 or 48 kHz quality in each direction, plus bi-directional control/monitoring data, with an extremely low latency of only six samples (125 microseconds at 48 kHz).
