Steel Head SPEAKON Jack Male-NEUTIK Code: 43751621

The Neutrik SpeakON NL4 is the industry-standard audio connector for high-power amplifiers and loudspeakers. It is designed for high-current environments. It uses a secure twist-lock system that prevents accidental disconnections and electric shocks.

Key Details

• Pin Configuration: Features 4 poles (contacts), labeled +1, -1, +2, and -2.
• Power Rating: Handles up to 30 to 37 Amps RMS of electrical current.
• Compatibility: NL4 plugs can mate with 2-pole (NL2) chassis jacks, but 2-pole plugs cannot fit into 4-pole jacks.
• Wiring: Wires are secured using captive screws or solder cups.

How the Pins Work

Imagine the pins as roads for your audio signals. The NL4 provides two independent “roads” (circuits):

• Circuit 1 (+1, -1): Used for your standard main speaker.
• Circuit 2 (+2, -2): Used for advanced setups like “bi-amping” (sending separate highs and lows) or running a second speaker line.

Common Uses

• Standard Hookup: Connects a power amplifier to a passive PA (Public Address) speaker.
• Daisy Chaining: Allows you to link one speaker to another, sharing the same signal.
