GAC-1

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.

GAC-2/foil

Foil shielded installation cable using 7 x 0.20 mm tinned wires for IDT. Designed for wiring balanced audio signals

in a metal environment. Aluminium foil is melt with the PVC-jacket and will come off automatically when the PVC-

jacket is removed.

The twisting of the each 7 strands is so tight that once peeling the insulation of, the strands do not come apart and

the cable can be installed without additional handling.
