Neutrik NL8MPRXX Speakon 8-pole Male Chassis Connector

Neutrik NL8MPRXX Speakon 8-pole Male Chassis Connector

The Neutrik NL8MPRXX is an 8-pole speakON chassis connector: a panel-mount receptacle that fits into a loudspeaker cabinet or amplifier panel and accepts the matching 8-pole speakON cable plug. It is not a cable connector; it is the fixed socket on the equipment itself. With eight contacts arranged as four positive and negative pairs, a single NL8MPRXX carries up to four loudspeaker circuits, which makes it the standard fitting for multi-way loudspeaker systems that are bi-amped or tri-amped and would otherwise need several separate connectors on the panel.

Key features

• 8-pole speakON chassis connector for loudspeaker and amplifier panels
• Rated at 30 A rms continuous per contact, 250 V AC
• Metal square G-size flange with four countersunk thru holes
• Termination by 3/16 inch flat tabs
• Quick Lock twist-lock latching; contact is made only once fully locked
• Silver-plated copper alloy contacts with contact resistance of 2 mΩ or less
• Rated for more than 5,000 mating cycles
• Component certified to IEC 61984, accepted in equipment designed to IEC 62368-1

Eight poles for multi-way loudspeaker systems

A two-pole connector carries one loudspeaker circuit. A multi-way cabinet driven by separate amplifiers for its low, mid and high sections needs several circuits, and running them through individual connectors multiplies panel holes, cabling errors and setup time. The 8-pole format solves this by grouping four circuits in one keyed housing: the mating plug can only enter in the correct orientation, the four pairs stay in their assigned positions, and one connection completes the whole loudspeaker hookup. This is why 8-pole speakON is the routine choice for professional multi-way cabinets, line-array elements with multiple driven sections, and amplifier racks that feed them.

Panel mounting and termination

The NL8MPRXX mounts through the panel on a square G-size metal flange with four countersunk thru holes, and it can be fitted from the front or the rear of the panel to suit the cabinet or chassis design. Inside the equipment, wiring terminates on 3/16 inch flat tabs, the standard push-on tab size that also accepts soldering, so internal loudspeaker wiring can be built with crimped tab receptacles for serviceability or soldered for permanence. The metal flange and zinc diecast, nickel-plated shell give the connector the rigidity that a large, frequently handled cable plug demands of its panel socket.

Electrical ratings and the locking system

Each contact is rated at 30 A rms continuous with a rated voltage of 250 V AC, with dielectric strength of 1.5 kVac. Neutrik’s speakON locking system engages with a twist once the plug is inserted, and the design makes electrical contact only when the connector is fully locked, so a partially inserted plug cannot sit live and intermittent. The precise keyway prevents mismating, and the latch releases deliberately rather than pulling free under cable tension, which is the central safety advantage speakON holds over bare-wire terminals and quarter-inch jacks on high-power loudspeaker lines. Note that speakON connectors are for loudspeaker signals only and must never be used as mains power connectors.

Built for repeated professional use

The contacts are copper alloy with silver plating, holding contact resistance at or below 2 mΩ, and the connector is rated for more than 5,000 mating cycles, so it withstands the connect-and-disconnect rhythm of rental, touring and install work. The polyamide insert and flammability rating of UL 94 V-0 suit it to equipment built to professional safety standards, and its operating temperature range of minus 30 to plus 80 degrees Celsius covers storage and working conditions from cold trucks to warm amplifier rooms. For cabinet builders, repair workshops and amplifier manufacturers, the NL8MPRXX is the genuine 8-pole panel fitting the speakON system was designed around.

Fitted in place of worn or lower-grade sockets, or specified into a new multi-way build, the Neutrik NL8MPRXX provides the secure, high-current, four-circuit panel connection that professional loudspeaker systems rely on.
