Klotz Starquad SQ414Y 4 x 0.15mm Diameter Cores
The Starquad SQ414Y is a cable designed for microphone connections in stage use. The SQ414 features ultra-fine tinned copper strands that provide superb flexibility; the cable can also be used as a patch cable. Microphone signals are particularly susceptible to interference because of the high amplification involved, particularly in live environments with multiple electromagnetic fields.
The SQ414's design has four cores twisted together. Its intelligent wiring minimizes interference by electrically connecting opposing cores so that the four cores form two crosswise-stranded double cores (the 'star quad' of the name) in perfectly symmetrical stranding. The connected pairs of the SQ414 are colour-coded to simplify cable production. The SQ414 also features a spiral shield offering over 95 per cent screening.|Production note: cores are colour-coded white/white-green and blue/blue-orange.
