Cabo de coluna Omnitronic 3022130P, 2×2,5 mm², 20 m, preto

Omnitronic 3022130P is a 20 m speaker cable with two conductors of 2×2.5 mm² cross-section in black, designed for connecting passive loudspeakers and audio components. The cable offers a balance of flexibility and conductor area to support reliable signal transfer and sufficient power handling for home audio systems and small professional sound installations. A flexible outer jacket and clear polarity marking make routing, installation and maintenance straightforward.

Advantages

The cable combines 2×2.5 mm² conductors for low resistance and stable audio transmission over moderate distances, while the 20 m length covers typical room layouts and small venue setups. Its flexible rubberized jacket simplifies bending and concealment behind walls or along skirting boards. Visible polarity marking reduces the risk of incorrect connections, and the black outer color integrates unobtrusively into most environments.

Key specifications

How to use

Strip back the outer jacket and insulation from each conductor to the required length, taking care not to damage the copper strands. Connect the conductors to the corresponding terminals on amplifier and speaker, observing the polarity markings to maintain phase consistency. For permanent installations, route the cable away from mains wiring and secure it along its path using appropriate clamps or cable ties. For speaker terminals that require ferrules or banana plugs, terminate the conductors according to the connector specifications to ensure firm, low-resistance connections.

Recommendations

Use the 2×2.5 mm² cable for runs up to 20 m in typical residential or small commercial setups. Avoid running the cable in direct sunlight or outdoors unless additional protection is provided. Keep the cable separated from high-voltage mains runs to minimise interference, and check terminals periodically for corrosion or loosening to maintain reliable audio quality.
