BACH™ enables your product to perform throughout the many applications of different audio networking protocols, all while protecting your investment from coming shifts in audio networking standards. As standards evolve, your product development investment keeps pace. BACH™ takes the worry out of the network.

Overview

A single BACH-module provides a complete, ready-to-play networked audio solution with as many as 512 channels of bi-directional and glitch-less redundant streaming. The onboard dual-core ARM Cortex-A9 MPU includes its own Linux environment, enabling the development of custom embedded applications for device and network control and monitoring. A wide range of interfaces is supported, and COVELOZ’ comprehensive product development toolkit, complete with software and FPGA development tools, streamlines integration, dramatically lowering time to market and total-system-cost.

The BACH-module is currently offered in three software-defined configurations: Canon, Canon-lite, and Allegro, as summarized in the table below.
