speakON

speakON (Neutrik)

Locking speaker-level audio connector for amplifier-to-speaker connections.

Types

  • NL2: 2-pole (single channel)
  • NL4: 4-pole (bi-amp capable, most common)
  • NL8: 8-pole (quad-amp)

Common Uses in AV

  • Powered and passive speaker connections
  • Amplifier outputs to speaker cabinets
  • Subwoofer connections

Key Considerations

  • Locking twist connector — will not accidentally disconnect
  • NL4 is the standard — even for single-channel, use NL4 for compatibility
  • Pins 1+/1− = Channel 1, Pins 2+/2− = Channel 2
  • Never use for line-level audio — speaker level only
  • Wire gauge: minimum 14 AWG for runs under 15m, 12 AWG for longer
