Introduction

The CAB 4n is designed to mount in a standard EIA electronic equipment rack. Because the
CAB 4n includes forced air cooling, rack mounted vent panels are not required for most
installations. However, vent panels may be required in large installations where multiple units
are mounted in a single rack. It is generally accepted that a ratio of 2:1 usually provides
adequate performance. In installations where adverse conditions exist, and room temperatures
are likely to rise, additional vents should be installed.

What you will need


A MediaMatrix NION with CobraNet.

The latest NWare software. (Updates can be downloaded from the MediaMatrix website.)

A computer running Microsoft Windows, with monitor, mouse and keyboard.
 At least 1 CAB 4n with associated MM™ I/O 4 ch cards loaded.

A network switch connected to the CobraNet network.
Note: 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.

An assortment of CAT 5 cables.

An audio source, power amplifier and loudspeaker.

A small Phillips screwdriver and a T-15 Trox screwdriver.
In MediaMatrix, the minimum CobraNet network consists of a single NION, a CAB 4n audio
bridge loaded with appropriate MM™ I/O 4 ch cards and a single Ethernet switch. Many
systems will include more NIONs and CAB devices, but this is the most basic configuration.

This product should be installed so that its mounting position does not interfere
with proper ventilation. Do not block air intake or exhaust vents.
When dressing off wiring harnesses, take care with CAT 5 cables. Do not tie-wrap
bundles of CAT 5 wire too tightly. 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 data transmission errors.
It is possible for line level audio and data signals to contaminate microphone level
signals. We therefore recommend that the cabling for the different signal types is
separated.
