Van Damme
AVI series audio/video composite multicores
New for this catalogue is a range of audio and video composite multicores for the broadcast and 
presentation industries. There are two types based around the Van Damme miniature 
coax and blue series studio grade audio multicore inner pairs; and one which uses 
Van Damme standard 75 Ohm coax for the video cores. These cables provide an 
elegant solution for the transmission of analogue audio and video signals from source 
to destination within the same jacket. The standard 75 Ohm type 268-375-202 has 
also been tested successfully with serial digital video over 50 metres. 
 
Materials 
Van Damme now use a higher purity oxygen free copper for the conductors -Ultra 
Pure Oxygen Free Copper (UPOFC). The use of this material further improves the 
‘solderability’ and conductivity of the conductor resulting in faithful and transparent 
signal reproduction in use. 
 
Audio pairs: Polypropylene (PP)is used for the conductor insulation. This material has 
a higher temperature rating than most polyethylene insulation giving excellent 
resistance to ‘shrink back’ during soldering. Its inherent hardness makes it ideal for 
the thin wall insulation used by Van Damme in their analogue audio multicores. This 
thin wall insulation ensures that the overall 
diameter of these cables is kept to a minimum without compromising electrical 
performance.Electrically it is very similar to polyethylene with a low dielectric 
constant (2.25 for PP solid types) and high stability across the lower frequency 
ranges associated with analogue audio signals. 
 
Pairs are twisted together with a tinned UPOFC drain wire and shielded with an 
aluminium/polyester foil screen.The 150% coverage method employed ensures that 
the pair is fully screened and that the drain wire remains in close contact with the 
conductive aluminium foil allowing interference to be effectively taken to ground. 
These pairs are then overlaid with a flexible PVC 
composite jacket.
