The new SPX Series can deliver currents up to 50 Amps on all four contacts for audio applications. This means a single connector is capable of carrying the current load from amplifiers of over 1kW. Another unique design element is that electrical contact is made only after the connector is completely inserted and locked to prevent arcing when connected under load.
The new cable connector also consists of only three parts to make assembly faster and easier, and a one-piece internal chuck accepts cable diameters between 6 and 14mm. Termination is either with screw terminals or by soldering and the inserts accept stranded 6mm²/10 AWG wire. A right angle version (NL4FRX) will be available, as well as a kit to convert standard NL4FX connectors to the right-angled version without any additional wiring or soldering. The new Speakon can be ordered with boots in any of five colours (black, red, yellow, green and white) for instant identification, and the right-angle version can be colour-coded with coloured collars.
Additionally, the NL4FX is compatible with all current NL4M receptacles and the new NL4MMX adapter to convert a standard ‘female to female’ cable into a ‘female-male’ cable. The new secure double-locking mechanism employed by this adapter ensures that there is no danger of accidental disconnection.
