General advice includes:
•
Ensure the stand is not placed where it will be a trip hazard
•
Ensure the stand is rated to take the weight of the speaker comfortably
•
Ensure the legs are splayed out sufficiently to prevent toppling
17. Loudspeaker cables
From a rigging perspective, there are a number of points to consider regarding loudspeaker
cables:
1.
The “self” weight of the cable must be factored in to the total load to be flown.
Some typical cable weights are listed below for illustration:
Cable type
Connector type
Typical weight per
metre (grams)
2 x 2.5mm² (14AWG)
NL4
122 (0.269 lbs)
2 x 4.0mm² (12 AWG)
NL4
162 (0.357 lbs)
4 x 2.5mm² (14AWG)
NL4
160 (0.353 lbs)
4 x 4.0mm² (12AWG)
NL4
260 (0.573 lbs)
8 x 2.5mm² (14AWG)
NL8
350 (0.772 lbs)
8 x 4.0mm² (12 AWG)
NL8
500 (1.102 lbs)
E.g. For a system comprising an IF3115, 10 metres of 8 x 4.0mm² cable would add an
additional 5kg of weight per speaker.
2.
Cable management is necessary to ensure the cabling is held securely, and neatly in
place, and that the cable is not under any strain, which may cause damage to the
connections, undesired positioning or movement of the system.
3.
Never use a loudspeaker cable for “tying off” – the purposes of preventing the system
from rotating.
