Neutrik NL4MP-ST speakON 4-Pole Panel Mount Receptacle Screw Terminal

The Neutrik NL4MP-ST is a 4-pole speakON chassis receptacle designed for permanent installation in loudspeaker enclosures, amplifier rear panels, and touring audio equipment. It is the go-to choice for system integrators, touring engineers, and install technicians who need a durable, industry-standard termination point that withstands heavy production use.

The connector uses a Quick Lock metal insert in the locking zone, ensuring the mating plug makes electrical contact only after it is fully locked — eliminating the risk of intermittent connections during high-SPL or vibration-heavy environments. The precise keyway prevents mis-mating and contributes to repeatable, consistent signal paths across large installations or touring rigs with frequent connector cycling.

Glass-reinforced polyamide construction and a rated mechanical lifetime exceeding 5,000 mating cycles make the NL4MP-ST appropriate for any application where connectors are plugged and unplugged regularly. Screw terminals accept up to 4 mm² wire, accommodating the heavy-gauge cabling common in high-current loudspeaker runs. Unlike some proprietary chassis connectors, the NL4MP-ST uses a standard D-size countersunk flange with through-hole mounting, fitting existing cutouts on most professional enclosures and rack panels without modification.
