Audio cable Procab ALS15/1, Copper-Clad Aluminium (CCA) 16 AWG, 100 m, black/red

Procab ALS15/1 audio cable is a 100 m parallel loudspeaker conductor manufactured using Copper-Clad Aluminium (CCA) with a 16 AWG cross-section. The cable features a black and red PVC jacket with polarity indication and arrives without connectors, making it suitable for custom terminations. ALS Series CCA construction uses a copper outer layer bonded to an aluminium core (approximately 15% copper, 85% aluminium), offering a balance of solderability, reduced weight and lower material cost compared with pure copper, while maintaining better conductivity and mechanical strength than bare aluminium.

Advantages

The CCA design provides improved solderability and a copper surface for reliable terminations while keeping overall weight and cost lower than equivalent pure copper cables. The PVC jacket is flexible and contains clear polarity markings (black/red) for straightforward identification during installation. Supplied on a 100 m length, the conductor is suited to long runs common in speaker wiring and permanent installations, reducing the need for frequent splices.

Suitable for

• Loudspeaker wiring in venues and PA systems
• Permanent audio installations in residential or commercial buildings
• Long-distance runs between amplifiers and speaker arrays
• Custom cable terminations where connectors are fitted on site

Key specifications

• Cable type: Parallel loudspeaker cable (two-conductor)
• Conductor material: Copper-clad aluminium (CCA), approx. 15% copper / 85% aluminium
• Wire gauge: 16 AWG
• Length: 100 m
• Jacket material: Flexible PVC with polarity indication
• Colour: Black and red conductors
• Connectors: Supplied without connectors (bare ends)

How to use

Measure and cut the required length from the 100 m spool, strip the PVC jacket and expose the conductor ends following standard audio wiring practices. Use appropriate ferrules, soldering or crimp connectors depending on the chosen termination method, ensuring solid mechanical and electrical contact on the copper-clad surface. Respect correct polarity using the black/red markings to maintain phase consistency across speakers and avoid wiring errors that can affect sound quality.

Usage recommendations

For longer runs or higher power applications, verify amplifier and speaker impedance compatibility and consider voltage drop; when in doubt, use shorter runs or parallel runs as appropriate. Protect exposed cable runs in conduits or trunking for permanent installations and avoid sharp bends or mechanical stress to preserve conductor integrity and signal quality.
