2x2, 8x8, or 16x16 Channel CobraNet Module

CobraNet® technology, the de facto standard of digital audio networking technology from Cirrus Logic, has established itself as the product of choice for multivendor networked audio. The CM-2 is based on the highly integrated CS1810xx or CS4961xx CobraNet Silicon Series, providing an interface in the form of a compact, low-power, low-cost module. Featuring 2, 8 or 16 bi-directional channels, the CM-2 is designed to be easily integrated into a wide variety of audio products such as signal processors, mixers, amplifiers and self-powered loudspeakers.
