EV-2 CobraNet™ Evaluation/Developer’s Kit
Innovative Development Platform for CobraNet™ Products
CobraNet™, the industry-leading digital
audio networking technology from Cirrus
Logic®, has established itself as the product
of choice for networked audio. The CobraNet
solution leverages the rapid developments
in the computer networking industry to
provide an increasingly cost-effective
solution for audio professionals worldwide.
The EV-2 provides a means of easily
evaluating CM-2 CobraNet modules. It
also provides an example CobraNet
interface and can be used as a
development platform for CobraNet
products. The EV-2 comes standard
with CM-2 modules, but will work equally
well with CM-1 modules if needed.
The EV-2 Evaluation / Developers
kit includes:
The EV-2 Evaluation / Developers kit is
available for purchase with a signed
evalutation agreement. For additional
