Speaker cable electro base PBA400-LZ, professional 2x4.00 mm², high-current audio wiring

electro base PBA400-LZ is a professional speaker cable with two 4.00 mm² conductors designed for high-current audio wiring. The cable provides a low-resistance path between amplifiers and loudspeakers, intended for installations where reliable power transfer and minimal signal loss are required. Constructed for durability and stable electrical contact, this cable is suitable for extended runs in venues, studios and domestic systems that demand consistent performance.

Advantages

The cable combines a two-conductor 4.00 mm² cross-section with construction optimized for high current capacity and low attenuation. Its design ensures consistent impedance and reduced heating under load, supporting clear audio reproduction even at elevated power levels. Robust outer insulation protects the conductors from mechanical stress and environmental factors commonly encountered in professional installations.

Suitable for

• Wiring between power amplifiers and passive loudspeakers in professional sound systems
• Fixed installation runs in concert halls, clubs and event venues
• Studio monitoring and control-room speaker connections
• Home theater and high-power residential audio systems

Key specifications

• Conductor configuration: 2 conductors
• Conductor cross-section: 4.00 mm² per conductor
• Purpose: speaker / high-current audio wiring
• Electrical characteristic: low-resistance, suitable for high current
• Construction: flexible conductors with protective outer insulation
• Recommended use: fixed and portable audio installations

How to use

Strip the insulation at connection points to expose sufficient conductor length for a secure termination, taking care not to nick or damage the conductor strands. Use appropriate speaker terminals, banana plugs, spade lugs or screw terminals rated for the conductor size and expected current. Maintain polarity consistently (positive to positive, negative to negative) along the entire signal path to avoid phase issues. Route the cable avoiding sharp bends, excessive tension and proximity to strong electromagnetic sources to minimize interference.

Usage recommendations

For long runs, calculate voltage drop based on conductor cross-section and expected amplifier output; with 4.00 mm² conductors this cable supports higher currents and lower losses than smaller gauge alternatives. Ensure terminations are tight and corrosion-free; for permanent installs, protect exposed terminations from moisture and mechanical strain. When installing in public venues, follow local electrical and fire-safety regulations regarding cable routing and containment.
