Installation

Pag e 9Peavey Electronics Corp

Installation

The CAB™16 Series product is designed to mount in a standard EIA electronic equipment rack. Because the CAB 16 includes forced air cooling, adding rack mounted vent panels is not required for most installations. However, it is recommended that common sense be applied to large installations where multiple units are mounted in a single rack. It is generally accepted that a ratio of 2:1 is a good rule of thumb that usually provides adequate performance. In installations where adverse conditions exist, and room temperatures are likely to rise, additional vents should be installed.

Do not block the fan or any vents when installing the CAB 16. Proper cooling is essential to maintain proper operation and long-term stability in this product.

When dressing off wiring harnesses, take care with CAT 5 cables. Do not tie-wrap bundles of CAT 5 wire too tight. Leave plenty of room for bends, allowing the cable to progress naturally from the RJ-45 connector. Creating tightly wrapped CAT 5 wire bundles can cause loose crimp joints and defective terminations.

To successfully install your new CAB 16 Series product, and perform the testing examples contained in this manual, you will need the following components:

• A MediaMatrix

MiniFrame 208nt-cn or MM™-760nt, MM™-960nt or

™

-980nt Mainframe.

• MWare 3.1.2 or later software.

• PC Monitor, mouse and keyboard.

• At least 1 MM™ DSP-cn CobraNet

™

DPU card for MediaMatrix.

• At least 1 CAB 16i and 1 CAB 16o CobraNet

™

Audio Bridge, OR 2 CAB 16d

CobraNet Audio Bridges.

• At least 1 generic fast ethernet 100 Base T network switch*.

• An assortment of CAT 5 cables.

• An audio source, power amplifier and loudspeaker.

In MediaMatrix, the minimum CobraNet network consists of a single MediaMatrix frame housing at least one MM DSP-cn CobraNet DPU card, CAB 16i and CAB 16o audio bridge and a single ethernet switch. Of course, most systems will include many more DSP-cn cards and CAB devices, but this is the most basic configuration.

* The selection of a proper network switch is critical for a successful implementation. Although CobraNet is an ethernet protocol, there are performance issues that must be considered when selecting this switch for use in CobraNet audio systems.

For the latest list of CobraNet compliant products, please refer to Peak Audio’s website at http://www.peak audio.com.

CAB™16 Series User Manual

Hardware vs. Software Devices

The CAB 16 Series of products is an integration of physical hardware and software. Within CobraNet™, there are even further integrations, that being the network itself, and the actual piece of equipment, in this case, the CAB 16. In software, the equipment is represented by a “Device” within the MediaMatrix MWare application. The CobraNet network is represented by a traditional MediaMatrix wiring block with inputs and outputs. The “wire” between these blocks is the configuration of audio signal flow with the MediaMatrix’s DPU. For proper operation of these products, a thorough understanding of all of these devices is required.

There is a very basic relationship between the CAB 16 physical product and its accompanying software device. Essentially, the software device is the “Control Panel” for the hardware. There are no physical controls on the CAB 16 itself, so all functions for it are accessible only from its software based control panel. This control panel is a yellowbox labeled “CAB 16”, and can be found under the Input/Output, CobraNet section of the Device Menu within the MediaMatrix software. There is one for each

model of CAB 16 product. I like to refer to this device as the “Taxi”, since it’s a yellow CAB......get it?

The figure below shows the relationship between the Taxi, its control panel and the actual CAB hardware.

The second half of this equation, as mentioned above, is the audio transport. This transport is the CobraNet network that carries audio from one location to another. Within MediaMatrix, this is represented by a block with “wire nodes” on it that represent the actual input and output points for the system. What is very important to note is that the hardware unit, the CAB itself, and the audio transport device DO NOT necessarily match up. For example, it is possible to have one output wiring block assigned to multiple CAB 16o units although generally, the input side is always a one-to-one relationship. In the figure below, you can see the two network blocks. The one with the nodes on the right of the block is an audio “input” position, the one with the nodes on the left side of the block is an audio “output” position. Each of these also has a control panel. The control panels for each are very similar, so don’t get them mixed up. You can tell which one is the “input” side by the “Receiving” label on the channel LEDs. These LEDs indicate that an audio data stream is successfully being received from a distant network location.

The Test View

In order to properly use this manual, it is recommended that a basic MediaMatrix view file be configured. This view file should have a minimum number of components and should include one each of the CAB

™

16i and CAB 16o, or, it should match exactly

your specific system hardware. The following figure is a good example of such a “test” file.

Once again....to summarize. It is very important to understand the relationship between the CAB hardware, it’s associated soft-

ware control software and the CobraNet

™

network, or “audio transport”. The blocks in this example labeled CobraNet 1A, 1B, etc. are transport blocks that receive digital audio from, and carry digital to, distant CobraNet network locations. This audio enters and exits the MediaMatrix system at these blocks. The wires represent the digital audio path within the MediaMatrix system. The blocks labeled CAB, the yellow “Taxi”, represent the actual CAB hardware. There must be one of these for each corresponding hardware piece. The hardware, via its control panel, can be “assigned” to any network audio channel, called a “bundle”. This bundle is also assigned in the CobraNet transport block. It is this bundle assignment that gets the audio from the CAB’s analog port and onto the network. If this is confusing to you, stop and re-read this section. It is vital to your ability

to successfully implement a CobraNet audio system using MediaMatrix products. If you understand it....kinda, but still need

help, read on....you’ll see how it all fits together as you start hooking up CABs and passing audio from point to point.
