| Two major categories of noise affect all audio cables: electrical
interference and microphonics. Unbalanced single core audio
cables are much more sensitive to electrical interference than
balanced cables which, because of their twisted pair
configuration, have the ability to mutually cancel EMI.
Microphonic noise is caused by a static charge generated when the
conductor is rubbed against its insulation. This occurs to some
degree whenever the cable is moved. The microphonic effect is
evident by a clicking noise in the system, usually occurring when
the cable is handled or moved. Gotham GAC-1 unbalanced cable has
been engineered to minimize these effects.
ADVANTAGES
- 1. RF-protection via "double Reussen shield"
- 2. Low Microphonics A conductive PVC layer over the
conductors insulation, allows any static build up to leak to the
shield and be grounded before it has any harmful effects (refer
to item 5 of figure).
- 3. Jacket A thick yet tough and flexible jacket protects the
cable.
CONCLUSION
Due to its quiet behaviour and high strength, Gotham GAC-1
unbalanced cable is ideally suited for live applications such as
guitar leads; it is equally suited for static applications such
as a phono interconnect lead.
