Does the IQwic 7 provide a listen bus for the PS8810CN and/or the IQ-PIP-USP3CN?

The analog listen bus was removed from the TCP/IQ amplifier PIPs in favor of using CobraNet for the Listen Bus. Now any product like amplifier or even a PS-8810C can pick off the bundle and channel and convert the digital signal to analog werever there is a network connection. This way you could send the Listen Bus audio from one amplifier to another in a control room on the other side of a facility without needing to run an extra pair of analog audio lines from each amplifier location.

A custom button matrix could be made, on a control Screen, with a button for each listen bus channel for ease of use. Assignment would then be given for routing the bundles and slots for each individual Listen Bus channel to the D to A conversion device. These bundles would be unicast (channels 256-65,000+) so as to only go to the D to A device-saving Bandwidwth. Also so as to not just keep adding bundles to the system, each button should be setup to clear out any previous settings.

Hi!

When creating a CobraNet listen bus, would you set up the amp PIPs to broadcast into the same bundle number, one at a time of course, and have the reciever permanently set to that bundle?
Or would it be better to have amps to send at individual bundle numbers and switch the receiver from one to the other bundle?

It would provide a little more flexibility to have each amplifier broadcast on its own bundle.

However each system is a little different, but the bundle per amplifier has been the most intuitive implementation we have seen so far.
