Sigma Electronics to feature OctaStream family at IBC2003
Sigma Electronics will display its OctaStream family of AES digital audio signal management products at IBC2003, in Stand #3.158.
All of the modules in Sigma Electronics' OctaStream family feature front-panel controls for controlling basic functionality, and include GUI software to control all of the units’ functions when paired with the optional CI705 control interface module.
Designed to cost-effectively address 8-channel audio and the integration of AES and multi-channel digital audio into a DTV stream, the OctaStream family is engineered to provide unique solutions to the timing, mixing and synchronizing challenges inherent in the delivery of digital audio. The line consists of the DA5320 Mixer & Subframe Router, the DA5315 Variable Delay Compensator, the DA5325 Sample Rate Converter and the SG5605 Audio Reference Generator.
The series is designed for Sigma’s new S5000 signal management frame, which allows full, unrestricted access to all modules, and is also capable of hot-swapping of all modules and power supplies. The high-density frame holds up to 10 modules, each with 10 connectors, and allows module status indicators to be fully viewable when the door is installed for ease of maintenance and error diagnosis.
The OctaStream product family includes:
DA5320 - Mixer & Subframe Router offers unique timing, mixing and synchronizing solutions for eight individual audio channels from four AES input streams. The unit derives its timing reference from AES input 1/2.
DA5315 - Variable Delay Compensator sets variable delay up to 10 seconds for each of four independent AES signals on eight channels. It is designed to compensate for inherent latency challenges with the video path, and allows delay to be selected in units of seconds or NTSC/PAL frames.
DA5325 – Sample Rate Converter serves as the audio equivalent of a video frame synchronizer. The module is designed to retime four asynchronous AES inputs to a local reference while maintaining perfect phase. DA5325 allows selectable conversion of sample rates from 28-108 kHz to 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz or can be steered by an external reference.
SG5605 - Audio Reference Generator introduces a unique method of tracking audio channels by generating AES tone/silence with 8 audible channel identifiers. It can operate as a standalone reference generator, or it may be locked to a master video reference for complete system synchronization. The unit is capable of generating simultaneous outputs of tone and silence, and features a user-selectable ID timing period that can be turned on or off on a channel by channel basis at the user’s discretion.
All of the modules in the OctaStream family feature front-panel controls for controlling basic functionality, and include GUI software to control all of the units’ functions when paired with the optional CI705 control interface module. To minimize compatibility issues in the marketplace, all of these new Sigma modules have been engineered to be fully compatible with NVISION’s NV500 enclosures.
