Cable management technology helps loudspeaker arrays fly

Sophisticated acoustic modelling helps sound engineers in theatres and concert halls achieve optimal clear sound and sonically uniform coverage around the venue. However, some flexibility is needed within the fixed installation to allow for the different audio projection needs of visiting performers. Traditionally, this has been achieved by connecting the fixed and moveable audio elements though slip rings, however their operation depends on breaks in the conduction paths. In high power, high quality systems this break can have an adverse effect on reliability and potentially signal quality.

The solution offered by Igus is the e-spool cable management system, which provides no-break connections between the amplifiers and speakers, eliminating reliability and signal quality issues. In the system, an e-chain carries the cables from the amplifiers guided by one roller, which maintains the correct length and tension via an integrated retaining spring. The twisterband connects the roll to the shaft block, which acts as the interface between the linear motion and the fixed end. Other benefits of the e-spool system are that there is never any tensile load on the cables and cable droop is eliminated to save space and keep working areas clear.
