QED Reference XLR 40 Analogue Cable

Authorised UK Dealer • Reference Balanced Interconnect

Product Overview

The QED Reference XLR 40 is a high-performance balanced analogue interconnect designed to deliver ultra-clean signal transfer between hi-fi and professional audio components.

Built on QED’s award-winning Audio 40 platform, it uses advanced Tri-Conductor™ geometry and ultra-low capacitance design to reduce timing errors and preserve signal accuracy across long cable runs.

Developed in partnership with Neutrik, it features professional-grade XLR connectors and integrated ferrite technology to minimise noise, interference, and signal degradation.
