CM-2

16x16 Channel CobraNet® Module

Overview

Description

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.
