Loudspeaker connectors are not general power connectors

Do not turn a familiar connector into a power substitute.

The useful distinction

Stop when the connector family, pole count, equipment role or required wiring is unknown. This guide supplies no wiring or live-work procedure.

Claim inspection dates: 2026-10-03 · Independent review pending

Guide note · not an individual product specification

The useful distinction

Understand the requirement.

Read the speaker and amplifier documentation together. A twist-lock appearance does not identify a safe power connection. [C135A]

The two-pole product documentation warns against interrupting current. [C135B]

Bounded facts, visible unknowns

Specifications and limits

Loudspeaker connectors are not general power connectors facts and limitations
Documented identification	Neutrik explicitly excludes its two- and four-pole speakON products from AC mains and power-supply use. [C135A]
Important distinction	The two-pole product documentation warns against interrupting current. [C135B]
Verified device list	Not included. Check exact device and accessory documentation.

A boundary, not an omission to guess around.

Record the exact device model and the label beside the port. Obtain its manual and the accessory documentation. Keep unknown properties unknown instead of filling them from a visually similar item.

Before you connect

What to check

Identify the exact loudspeaker connector family.
Check the amplifier output and loudspeaker input documentation.
Follow de-energized connection instructions; never substitute for mains or a power supply.
