Cable run vs copper core cross sectional area

One W8CT Two W8CTs in parallel

or W8CT/CM or two W8CT/CM

combination combinations in parallel

at the cluster.

Up to 50m 4mm² (or 2x 2.5mm²cores in parallel) 10mm² (or 2x 4mm²cores

in parallel)

Up to 100m 10mm² (or 2x 4mm²cores in parallel) Not recommended -

but use 2x 10mm² cores

in parallel if you must.

Q. Why the odd sizes?

A. Loudspeaker cables are available in a limited range of standard copper core sizes -

ie. 1.5mm², 2.5mm², 4mm², 6mm², 10mm² and 35mm².

2.4 System patching

A good system patch should:

1) Be electrically safe - ie be put together by suitably qualified electrical

technicians

2) Enable the system to provide the required sound quality, coverage and level

without feedback and without stressing its mechanical, electrical or electro-

acoustic components.

3) Be divided into easily understood sections (eg Main, midfield, downfill etc)

and clearly labelled so that adjustments may be made quickly and efficiently.

Although the last two points may seem insultingly obvious to users who are naturally

well organised, they are very important. Each Longthrow section may be covering

several thousand people and fairly minor mis-patches can have major consequences

bearing in mind that outdoor events - particularly orchestral concerts - are often

competing with noise from food and drink stand generators, over-flying aircraft, local

traffic etc.
