NL4 vs. NL8 Speaker Cable: What’s the Difference?
1. What Are NL4 and NL8 Speaker Cables?
NL4 and NL8 speaker cables generally refer to cables from the Neutrik Speakon series. These twist lock cables are typically used to connect components in professional sound reinforcement systems, such as speakers and amplifiers.
A Speakon cable normally has a male speakon connector at both ends. The loudspeaker set uses female chassis connectors. The twist lock design can keep a secure connection of your PA speaker system.
In this article, we will explain the main differences between NL4 and NL8 speaker cables.
What Is an NL4 Speaker Cable?
An NL4 speaker cable uses a 4-pole Speakon connector.
It has four conductors, connected to:
- 1+
- 1-
- 2+
- 2-
It carries a total of two speaker signal channels, capable of driving two speakers or a bi-amp setup.
Important:
NL2 and NL4 connectors have the same physical shape. Some suppliers may use NL4 connectors to make NL2 Speakon cables.
Be sure to pay attention to this when purchasing—an NL4 Speakon cable should have four conductors.
What Is an NL8 Speaker Cable?
An NL8 speaker cable uses an 8-pole Speakon connector and eight conductors speaker cable, connected to:
- 1+
- 1-
- 2+
- 2-
- 3+
- 3-
- 4+
- 4-
This allows the cable to carry four speaker circuits.
This type of cable, along with the 8-pin DO series cable, is used in line array systems for professional live performances.
2. NL4 vs. NL8: Key Differences
The main difference is simple: NL4 has four conductors, while NL8 has eight.
| Feature | NL4 Speaker Cable | NL8 Speaker Cable |
| Number of conductors | 4 | 8 |
| Speaker circuits | Up to 2 | Up to 4 |
| Typical applications | Professional speakers, bi-amping | Larger PA and line array systems |
| Connector | 4-pole Speakon | 8-pole Speakon |
| Common cable type | 4 × 2.5 mm²/4 × 4 mm²(12awg) | 8 × 2.5 mm² / 8 × 4 mm²(12awg) |

3. What Is an NL8 Breakout Cable?
An NL8 breakout cable is also called a Y-adapter cable.
One end of this cable features an NL8 Speakon male/female connector, while the other end has four NL2 Speakon cables or two NL4 Speakon cables.
Common configurations include:
- NL8 → 4 × NL2
- NL8 → 2 × NL4
This cable can split the NL8 bus into NL2 and NL4 branches. This helps prevent errors caused by having too many NL4 and NL2 Speakon cables on stage.
When Is an NL8 Breakout Cable Useful?
Similar to a Socapex fan-out cable, it distributes the signal from an amplifier to TOP or SUB speakers.
Using this cable makes your audio wiring more efficient and reliable, and keeps the stage tidier and safer.
4. Conclusion
Through this article, we’ve gained a general understanding of the differences and uses of NL4 and NL8 Speakon cables. The NL4 has 4 conductors, while the NL8 has 8. An NL4 Speakon cable can power two speaker units, and an NL8 can power four.
