1 DESCRIPTION
The Hono CobraNet 16.16D is a CobraNet interface designed for use in the professional installed sound market.
This device receives up to 16 channels of CobraNet and sends them to 16 AES/EBU (8 stereo) audio outputs,
while simultaneously inputting 16 channels of AES/EBU (8 stereo) audio and transmits them up to 16 channels of
CobraNet.
The Hono CobraNet 16.16D has been purposely designed to compliment and fully integrate with all of today's
CobraNet compatible DSP products. In addition, this is the ideal solution for many situations where a project
requires numerous channels of digital audio routed throughout a facility, but doesn't require a dedicated DSP
processor.

Page 11: Introduction
A graphics display on the unit’s front panel shows peak meters and CobraNet status. AudioScience provides application software that may be used to set up the Hono CobraNet interfaces. ASIControl can be used to set all internal features of the unit (such as levels) and to set CobraNet routing connections to be set up between the Hono CobraNet interfaces and any other compliant CobraNet device on the network. -
Page 12: Cobranet
Similarly, the mechanism for receiving bundles is “receivers.” Each CobraNet device has several transmitters and receivers and so can simultaneously send and receive audio channels using several different bundle numbers. This capability supports audio links between many different CobraNet devices. www.audioscience.com 22 August 2011... -
