More info

With its expertise in custom audio / video cables and the success of its CS-331B mains cable, ELECAUDIOimagined a mains cable "IN WALL"specially adapted for walls. Indeed, you can pass this CS-331TPE cable through your walls thanks to its relatively small diameter (Ø12mm) and especially its sheath made of resistant TPE at high temperatures, while maintaining electrical and sound properties and performance.

Thus each driver of the CS-331TPE consists of 7 strands of 10 strands of deoxygenated copper OFC of each 0.25mm in diameter, ie a section of 3.5mm² per conductor .

These 3 conductors with the highly studied structure are encapsulated individually in PVC sheaths marked with acolor code Yellow / Blue / Brown. The three beams thus formed are themselves isolated from each other and held in a distant order by means of a cotton garniturewhich provides both flexibility and firmness to the whole.

Then there is a shielding made from a aluminum strip. Alongside this line of defense slips an OFC copper drain wirethe cable from one end to the other to ensure a linear earthing , synonymous with enhanced protection against radio interference(RFI) andelectromagnetic (EMI).

A protective sheath in TPE of 1mm thickness completes this work, and finishes making the CS-331TPE particularly resistant to the harshness that can be found in walls and extreme temperatures.
This cable which uses a TPE sheath meets the standards for fixed installations, in case of fire this material is flame retardant, low smoke emission and halogen-free.

Acheté pour alimenter mes amplificateurs Jadis JA 200
Câble Secteur de bonne fabrication, résistant et assez souple pour son diamètre, pas difficile à monter à condition de bien dégager les fils d’alimentation de la garniture en coton et du fil de drain.
Assez mélodieux, pas de dureté, médium aigu un peu descendant, grave ample mais sans excès, spatialisation et dynamique moyenne. Globalement la reproduction est un peu triste, sonne mate et manque, de respiration.
Ce câble peut aller sur des électroniques avec une prédominance du médium, haut-medium, aigu, mais ne convient pas sur mon système.

Excellent câble
J'avais besoin de puissance. Les 3x3,5mm² font merveille.
Je l'ai habillé d'une gaine nylon pour faire joli.
D'un cote, j'ai mis une prise Schuko PS-24GB, faite pour les grosse puissance- et de l'autre un presse étoupe RA-01B qui se met en lieu et place d'une prise IEC (même entraxe de fixation). Ca donne une ligne d'alimentation avec une capacité en courant énorme. Pas de problème pour les gros appels de courant.

Puissant et mélodique
Points forts : grave ample et puissant, caractère enjoué et mélodique, réelle présence des instruments (ressemble beaucoup à la musicalité Nad). Points faibles : manque d'ouverture, finesse et de subtilité (bande passante écourtée et très descendante). A réserver aux électroniques au caractère très montant (Atoll, Rotel, Yamaha, etc).
