SWAMP Stereo 3.5mm (Mini-Jack) to Mono 6.35mm (1/4" Jack) 'Stereo to Mono' Audio Cable

Combine Stereo into Mono
This cable will combine both the left and right channels of audio from a headphone mini jack into a single mono signal containing equal parts of both the left and right channels. Great for plugging a smartphone, laptop or any device with a minijack headphone output into a mono input on a line input on a mixer or even into a guitar amp input.

Split a Mono Signal into a 'Stereo' Signal
Can also be used in the opposite fashion, to split a mono signal from a 1/4" jack connector, into 2 identical signals that will pass through the Tip and Ring of the 3.5mm mini jack connector. Ideal for recording a mono signal into stereo line level jacks on PC sound cards.

Quality Cable and Connectors
Our slim 4.4mm diameter cable still had thick 23AWG conductors and tight spiral shield, but has a thinner outer PVC jacket giving the thinner overall diameter. Ideal for patching smartphones and laptops, ensuring the weight of the cable does not pull the plug out of the connector. Using professional quality connectors, OFC conductors and a tight and thorough spiral shield, this cable is designed to transfer your signal without interference and be flexible and withstand the rigours of constant use.
