Sigma Electronics is introducing its OctaStream family of AES digital audio signal management products at NAB2003. The new platform is designed to address eight-channel audio and the integration of AES and multi-channel digital audio into a DTV stream.
The line consists of the DA5320 Mixer & Subframe Router, which has timing, mixing and synchronizing for eight audio channels from four AES input streams; the DA5315 Variable Delay Compensator, which sets variable delay up to 10 seconds for each of the four AES signals; the DA5235 Sample Rate Converter, which allows selectable conversion sample rates; and the SG5605 Audio Reference Generator, which tracks audio channels by generating AES tone/silence with eight audible channel identifiers.
The OctaStream family is used with Sigma's S5000 signal management frame, which can "hot-swap" all modules and power supplies. The frame can hold up to 10 modules, each with 10 connectors. It is compatible with NVISION's NV500 enclosures.
