CobraNet devices transmit and receive digital audio (48 or 96 kHz, 16, 20 or 24 bit) in bundles of up to 8 channels. The number of chan-
nels per bundle can vary, depending on settings for latency and resolution. The number of bundles available depends on network band-
width.
Each CobraNet bundle has a number from the following ranges:
0:
Disables the receiver or transmitter.
1 thru 255:
Multicast mode (many receivers can access the same bundle).
256 thru 65,279:
Unicast mode (allows only one receiver to receive the bundle).
In order for CobraNet devices to communicate,
their Tx (Transmit) and Rx (Receive) bundle
numbers must match. RHAON devices are
equipped with two receivers and two transmit-
ters, their bundle numbers must be assigned
correctly so they can send and receive audio via
the network. RHAON software makes this easy.
Typically, the settings of a CobraNet source will
have already been established with the source’s
own proprietary software. However, you can set
or reset both receiver and transmitter bundle
settings of any device found on the CobraNet
network using RHAON software.
The first step in setting up CobraNet routing is to
drag the CobraNet Source that was detected by
Scan Network into the system.
The CobraNet Source and the devices connect-
ed to it must have the same Sample Rate and
Latency settings. Right clicking on the CobraNet
Source Icon will open a pop up screen showing
the Sample Rate and Latency settings. We sug-
gest you accept the Source’s default settings
unless you have a specific reason to change
them.
You will then want to check the device settings to
make sure they are the same as the Source’s
settings. The settings must be the same for the
source and for all devices connected to it.
While latency may be changed here via point-
and-click, the sample rate is pre-programmed in
the DSP firmware running in the loudspeaker.
You can switch sample rate by uploading the
appropriate firmware to your device. Please refer
to “APPENDIX III: Updating DSP Firmware” for
information on how to upload new firmware to
your device.
Next, check the bundle settings of the CobraNet Source device. The Source in our example has 4 Receivers and 4 Transmitters. The red
triangles on the left of its icon represent Rx bundles and the green triangles represent Tx bundles. Right clicking on one of the triangles
will open a pop up window that shows the bundle number and allows you to change it.
