## Long description

Procab CLS240-B2CA/3 is a 2-conductor speaker cable with two 4 mm² (11 AWG) copper conductors supplied on a 300 m reel. Designed for fixed audio installations, the cable offers low electrical resistance and reliable signal transfer for loudspeaker connections. With CPR Euroclass B2ca fire-performance classification, it meets stricter safety requirements for installations in public and commercial buildings where improved reaction-to-fire properties are required.
Advantages
The cable combines solid copper conductors sized at 4 mm² for low attenuation and consistent audio performance over long runs with a construction suitable for permanent installation. Its Euroclass B2ca rating provides enhanced fire safety compared with lower-class cables, making it appropriate for venues with regulatory requirements. Supplied on a 300 m reel, the cable is convenient for extended runs and reduces the need for multiple joins.
Suitable for
 Fixed loudspeaker wiring in theatres, concert halls and auditoriums
 Commercial audio installations in retail, restaurants and hotels
 Studio patching and permanent AV installations in broadcast facilities
 Public address systems in schools, hospitals and transport hubs
Key specifications
 Conductor configuration: 2 conductors, 4 mm² each (approx. 11 AWG)
 Conductor material: copper for low resistance and good conductivity
 Length: 300 metres per reel
 Fire performance: CPR Euroclass B2ca
 Intended use: permanent/fixed indoor audio installations
How to use
Route the cable along planned cable trays, conduits or fixed cable channels, avoiding sharp bends and sources of excessive heat. Strip the outer sheath and prepare conductor ends using appropriate cable-stripping tools, then terminate to speaker terminals or binding posts ensuring correct polarity. For long runs, verify impedance and level matching at the amplifier to maintain consistent audio performance. Use appropriate grommets or sealing where the cable passes through walls or fire barriers, and follow local electrical and building codes during installation.
Usage recommendations
For best results in professional audio systems, use this 2 x 4 mm² speaker cable for medium to long-distance runs where low resistance is important. Match cable length and conductor size to amplifier power and speaker impedance to minimise power loss. If the installation requires additional mechanical protection or outdoor exposure, add suitable conduit or select cables with outdoor-rated jackets.
