VTG introduced an EtherSound-based Digital Audio Networking Modules prototype at InfoComm 2005 (Las Vegas, June 6-11). The targeted applications range from fixed installations to temporary setups including live and touring sound, churches, government, broadcast and more.
The 16-channel rackmount device uses D-sub connectors on the rear for analog audio and RJ-45 connectors on the front, utilizing the low latency Ethernet-compliant EtherSound network audio protocol. The 16-mic/line level analog inputs in 1RU and can be built into a 64x64 audio network over Cat-5 cable. The sampling frequency is 48 kHz with 24-bit ADC converters with 48V phantom power available on each input. Programmable mic gain ranges from 0 to 66 dB in 0.5 dB steps and maximum input levels at +10 dBu/2k. There are 80 Hz low-cut and 12 kHz high-cut filters available and additional transceivers can be added to change from Ethernet category cabling to optical fiber cabling. A 1RU 16-channel line outputs is available to interface with existing analog equipment.
A person using an EtherSound compliant digital console will only need the input module, while a person using an analog console will need both the input and output modules.
