The Neutrik speakON XX Series 4-pole panel receptacles are the industry benchmark for loudspeaker and amplifier chassis interconnections in professional live sound and installed audio. Designed for audio engineers and systems integrators who demand reliable, repeatable connections under demanding conditions, these receptacles make contact only once fully locked — eliminating the risk of accidental disconnection mid-performance or during transport. The Quick Lock mechanism and precise keyway ensure consistent mating across thousands of cycles, making them the logical choice for touring systems, fixed installs, amplifier racks, and speaker enclosures.

Termination via 3/16" flat tabs accepts NLFASTON connectors or direct soldering, giving installers flexibility at both front and rear mounting orientations via countersunk through holes. The glass-reinforced polyamide shell meets UL94 V-0 flammability standards, while silver-plated copper alloy contacts and a stainless steel locking element hold up under continuous high-current audio loads. Full compliance with IEC 62368-1 via IEC 61984 component certification means these receptacles meet modern AV safety requirements without workarounds or caveats.

For integrators standardizing on a single connector family across a mixed install — combining D-flange and round-flange panels — the XX Series line provides consistent electrical performance across all flange configurations, simplifying inventory and serviceability in the field.
