Albalá Ingenieros | Manual IMB2000C01
The IMB2000C01 module provides one input and one output for MADI digital audio and
the electrical Ethernet interfaces.
• MADI IN and MADI OUT are the input and output BNC connectors, respectively, for
AES10 standard signals, better known as MADI.
• ETHERNET 1 and ETHERNET 2 are the Ethernet interfaces used to transmit and receive
audio streams as per the AES67 standard. They are also used to synchronize the device
using IEEE std 1588.
The front panel has not been designed to support mechanical stress. All cabling in the
rack where the mounting frame is located should be properly supported so that the front
panel does not provide mechanical support.
3.5.1. Ethernet connections
The Ethernet connections are made using RJ-45 connectors. The cabling used to make
the UTP connection should be Category 5 or higher (5e or 6) in order to guarantee
proper operation at 1 Gbps.
3.5.2. MADI audio electrical connections
The electrical connectors for MADI audio are all BNC type. The following are a series of
recommendations to keep in mind when making these electrical signal connections.
The BNC connectors used on the cables should be able to handle high frequency
digital audio signals, and it is highly recommended that a manufacturer of recognized
quality be used.
The coaxial cable used should be Belden 1694A or similar. This type of cable achieves
the greatest reach and is also the cabling type for which the equalizers in the
IMB2000C01 are designed. The cables that transport the signal between the module
and other devices should preferably be of a single section, avoiding "barrel"
female-female joiners and multi-section cable runs. If a run of cable must be divided
in two, the same type of cabling should be used for both sections.
RG-59 or similar cables meant for analog video are not recommended for digital audio
unless the lengths are very short.
