The Supra Y-Link is a twin conductor cable, designed to carry the single signal from the "sub-out" socket of a AV receiver or processor to the twin inputs of an active subwoofer. For good binding protection 'termination trousers' are fitted.
Low capacitance and high interference immunity make longer cable runs possible.
This cable suits an amplifier with a single subwoofer RCA output and a subwoofer with stereo RCA inputs.
