Neotech’s NECE-3001 is a cable for headphones and IEM applications (in-ear monitor) with 4 Litz UP-OCC copper conductors, PVC insulation and black Nylon sheath.
Each strand of the 4 conductors is polyurethane coated, this reduces the skin effect giving optimum performance. This coating needs to be removed before use. This is best achieved by using a solder bath or running the exposed end repeatedly through a bubble of molten solder on the tip of a hot soldering iron. Such a design is particularly suitable for audio use as it improves conductivity and limits cable resistivity, resulting in superb audio reproduction.
Overall diameter: 3mm
Conductor with insulation: 0.9mm
Copper conductor: 0.6mm
A multimeter is essential to use this cable to identify the conductors. The cable is built up of 4 conductors 2 red and 2 blue. The cable is not shielded
The 4 conductors are made up of the same thickness and number of strands. Wire them as detailed below. Where there is only one point for the earth join on your plug/socket join the right and left earth wires together.
Left channel signal – 1 x blue
Left channel earth – 1 x blue
Right channel signal – 1 x red
Right channel earth – 1 x red
