Red Series Plasma Grade video multicore
Van Damme Red Series Video multicores are 4
and 5 way versions of the Van Damme
standard 75 Ohm coaxes. Designed for use in
the Presentation and Broadcast industries, they
are commonly used for the transmission of
video signals such as RGBHV and RGB Sync
over longer distances - up to 100 metres for
analogue video signals. They are flexible but
also very robust and are ideal for multiple rig
and de-rig situations due to the attention paid
to their construction,
overall diameter and
weight.
Applications
• Extended transmission of RGBHV and RGB Sync video signals
• Can be used with confidence at 100 metres
Application notes
• Suitable for SDI use up to 138 metres
• Uses RG59 type crimp connectors
• Ultra pure oxygen free copper for outstanding 
sonic integrity
Transmission length guidelines
• These transmission lengths have been calculated throughout to
a maximum attenuation of -30dB at the frequency corresponding to
half of the actual signal data rate for SMPTE 259. SMPTE and
others advise that 90% of this cable length introduces an
appropriate safety factor- the chart below includes an 80% safety
factor as jitter and other factors can increase dramatically in the last
20% of a cable run.
