2-, 4- and 8-pole speakON

Which pole count and equipment wiring does the loudspeaker system document?

Computer-generated illustration, not a photograph. — P127 · Connector2-pole speakON loudspeaker connector

How they differ

2-pole speakON loudspeaker connector Read the connector family and pole count in the amplifier and speaker documentation; do not rely on a twist-lock outline.
4-pole speakON loudspeaker connector Record the exact connector designation from the equipment manual and compare the housing keying; do not assume a mating or wiring arrangement.
8-pole speakON loudspeaker connector Match the exact loudspeaker and amplifier documentation and never use the connector family as a mains-power substitute.

Two-pole versus four-pole speakONPole count does not provide a wiring map or power approval.TOSLINK vs Mini-TOSLINKStandard TOSLINK and Mini-TOSLINK are different optical-audio connector forms. Mini-TOSLINK can resemble a 3.5 mm jack, so confirm optical support from device documentation.3-pin Mini-XLR versus full-size 3-pin XLRAre you looking at the compact Mini-XLR/Tini-QG form or a full-size XLR connector? Matching three-pole counts do not make the shells interchangeable.3-pin versus 4-pin Mini-XLRDoes the compact Mini-XLR/Tini-QG form have three or four conductors? Conductor count does not establish the device wiring or signal role.3.5 mm TRS vs TRRSContact arrangement is a visual clue. Signal assignment still needs device documentation.4-pin versus 5-pin Mini-XLRDoes the compact Mini-XLR/Tini-QG form have four or five conductors? Do not infer a pin assignment from count alone.

Source links: S211 · Evidence trail → (private workspace)

C208B · P208

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

Claim scope: Exact component role and retention. No amplifier channel allocation, bridge-mode wiring, cable rating or power-supply use is established.
