ASI5408, ASI5416, and ASI6416 PCI CobraNet Sound Cards


The ASI5408, ASI5416, and ASI6416 are professional PCI Express CobraNet sound cards designed for use in the installed sound and entertainment markets.

Using Cirrus Logic's CobraNet technology for streaming audio over Ethernet, the ASI5308 provides 8 channels of CobraNet receive and transmit and the ASI5316/ASI6316 provides 16 channels of CobraNet receive and transmit. They can be connected to any CobraNet-compliant device and have dual-redundant CobraNet interfaces.

The ASI5408, ASI5416, and ASI6416 are based on the TMS320C6713 VLIW floating point DSP connected to a high-speed bus-master PCI Express interface.

AudioScience's MRX technology allows up to 8 (ASI5408) or 16 (ASI5416/ASI6416) streams of different formats and sample rates to be played, recorded, and mixed over CobraNet. For the ASI5408/ASI5416, a choice of 8, 16, 24, and 32bit PCM is available on all streams. For the ASI6416, a choice of PCM, MP3, or MPEG layer 2 compression is available on all streams.

AudioScience provides ASIControl, an application that allows CobraNet routing connections to be set up between the ASI5408, ASI5416, and ASI6416 and any other compliant CobraNet device on the network. Alternatively, third party CobraNet design and management software may be used.
