This D'n'A series (Digital and Analogue) cable is designed to be suitable for both digital and analogue audio signals, with an impedance of 100 ohms which has been proven to be suitable for AES/EBU digital audio as well as analogue microphone and line level signals. Wire insulation is polypropylene, which shrinks back minimally during soldering (considerably less than PVC or polyethylene).
Wiring specifications for many public buildings now call for LFH cables to be used in certain areas, notably in corridors, risers etc. Under combustion circumstances, LFH cables have a significantly reduced smoke emission, and the gaseous products contain no toxic halogens.
FSM-LFH series cables are technically identical to standard FSM series, apart from the use of LFH materials.
