8-pole speakON loudspeaker connector

The eight-pole speakON form is a high-contact-count loudspeaker connector, distinct from AC mains connectors.

Also called NL8 NL8FC 8 pole speaker connector Speakon 8

Eight poles do not define channel allocation, bridge mode or amplifier wiring.

Look for

Match the exact loudspeaker and amplifier documentation and never use the connector family as a mains-power substitute.

The useful distinction

Recognize it. Then verify it.

The eight-pole speakON form is a high-contact-count loudspeaker connector, distinct from AC mains connectors. [C208A]

Neutrik classifies NL8FC as a female speakON cable connector and specifies a Quick Lock latch; the product is intended for loudspeaker connections. [C208B]

The ST-NL8FC sheet distinguishes two longitudinal exterior views from a separate insert-detail view. The latch is visible on the exterior view labelled Rear side. [C208C]

Use the source-backed form or position count only for identification. Resolve ratings, protocol, direction, wiring, cable construction and exact device support from the relevant equipment and component documentation.

Before you connect

What to check

  1. Identify the exact connector family and variant from the equipment or cable documentation.
  2. Keep shape, contact count, protocol, electrical rating and device support as separate facts.
  3. Do not force, rewire or adapt a connector from this recognition record; resolve the remaining requirements first.

Pins & wiring

Pinout

Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.

What the status labels mean
Confirmed
Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source
Only one underlying document, or one pass, supports this assignment.
Device-specific
Supported for the named equipment or wiring only. Check your device’s manual.
Unverified
Missing or conflicting evidence. Do not wire from this row.
Not connected
The source explicitly says NC, no contact or no pin for this wiring.

What is not established

This field note does not approve a connection, adapter, cable assembly, rewiring scheme or fabricated part. It intentionally omits unsupported pin assignments and mechanical tolerances.

Loudspeaker service is not mains service

NL8FC is the named female cable connector used for the study. Its Quick Lock latch helps distinguish the component; it does not establish amplifier channel allocation or bridge wiring. The manufacturer explicitly excludes speakON from AC mains or power-supply use.

An insert-detail view is not a mating face

The linked sheet labels two longitudinal exterior views and a separate insert detail. The original study uses only the latch-side exterior. The terminal detail is deliberately not transformed into an invented front contact pattern.
