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.

Dark pinout view

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.

Neutrik 2-pole speakON contact designations (NL2MP chassis, NL2FXX cable)

View and evidence limits

Contact designations as moulded/printed by Neutrik; BDA 458 shows the NL2MP from the mating side, BDA 638 shows the cable insert wiring side.

P127 speakON 2-pole — **Agree** (contacts 1+ and 1âˆ’) — Neutrik only; no amplifier document found by either pass.
The designation identifies the contact only; what it carries is set by the equipment.
No amplifier or loudspeaker manual specifically using 2-pole speakON was retrieved.
Intermating behaviour (which receptacle contacts a 2-pole plug engages) was not established from a Neutrik document in this pass.
