Description

The Neutrik NP3X is a 6.3mm (1/4-inch) stereo jack plug with all-metal construction, designed for professional audio connections requiring a three-pole TRS (tip-ring-sleeve) configuration. The body, chuck and contact housing are machined from metal rather than plastic, providing enhanced shielding against RF and electromagnetic interference while maintaining structural integrity under repeated connection cycles.

Used in studio patching, live sound systems, instrument connections and headphone terminations, the NP3X handles stereo signals, balanced mono signals and insert point connections on mixing consoles and outboard gear. The plug fits standard 6.3mm sockets on amplifiers, mixers, effects units, synthesisers and professional headphones. The metal chuck provides a secure cable grip with integrated strain relief that protects the solder joints and cable conductors from flexing damage during stage use and frequent re-patching.

The solder terminals inside the plug accommodate cable conductors up to 6mm outer diameter, with clearly marked tip, ring and sleeve contact points for straightforward termination. The plug accepts both shielded stereo cable and balanced cable configurations. Neutrik manufactures the NP3X to Swiss precision engineering standards, with gold-plated contacts that maintain low contact resistance and resist oxidation over time. The metal body threads together with a knurled barrel that can be hand-tightened without tools.

Frequently Asked

What cable diameter does it accept?

The NP3X accommodates cable outer diameters up to 6mm. The internal chuck and strain relief clamp onto the cable jacket to provide mechanical support and prevent stress on the solder joints.

Is it suitable for balanced connections?

Yes. The three-pole TRS configuration supports balanced mono signals (tip = hot, ring = cold, sleeve = ground) as well as stereo signals (tip = left, ring = right, sleeve = common ground). The application depends on the connected equipment.

Can it be soldered by hand?

Yes. The solder terminals are accessible once the outer barrel is unscrewed from the plug body. The tip, ring and sleeve contacts are clearly marked for straightforward cable termination with a standard soldering iron.

What's the difference between NP3X and plastic-bodied 6.3mm plugs?

The all-metal construction provides better shielding against interference and greater mechanical strength under repeated connection cycles compared to plastic-bodied plugs. The metal barrel also dissipates heat more effectively during soldering.

Shipping & Returns

Free worldwide delivery

Free worldwide delivery on all orders over £99. International orders for third-party brand products may be subject to an additional courier surcharge based on volumetric weight, particularly on larger lighting fixtures — if a surcharge applies, our team will email you with the amount before dispatch and you can proceed or cancel for a full refund. See full delivery terms.

Returns

30-day returns window from delivery. As all our products are electrical or lighting goods, returned items must be inspected and recertified by a qualified electrician before resale — the cost of this inspection (25–40% of the item value) is deducted from your refund.
