Puissance pure
-
Tous les modèles d’amplificateurs fournissent des puissances de sortie extrêmes de 8 kW à 30 kW. Cela permet une réalisation avec succès de toutes les tâches liées au renforcement du son chez les installations fixes comme dans le touring business. La stabilité de charge excellente garantit une contrôle pure de charges de 2 ohms. “Capable“ et “apte“ ne décrivent pas l’autorité avec laquelle ces amplis contrôlent les haut-parleurs dans une manière audiophile et dynamique.
-
Un démarrage à froid en Russie à -40°C ou une chaleur d’été brûlante avec 40°C sur le pré – ces amplificateurs vous donnent une amplification pure, audiophile et vigoureuse dans toutes les conditions. Leur haute efficacité de plus de 85 % et leur concept sans compromis de l’industrie aérospatiale et automobile rendent des puissances et des courants de sortie sans pareil.

Super cool
-
Fiable
-
La haute fiabilité se montre depuis 2004 chez tous jobs de renforcement du son. Soit dans le mode d’emploi à 2 ohms sur des camions de hardstyle techno, chez de grands festivals ou de plus petits évènements avec un seul ampli. Avec cinq modèles on peut définir et organiser un pool de matériel uniforme dans les secteurs de location et touring avec une rentabilité optimale. Avec deux entrées et sorties les amplis sont très bien utilisables pour toutes sortes d’applications.
-
La K2 librairie de haut-parleurs avec actuellement 520 presets et 300 espaces mémoire DSP en interne grandit continuellement. Cela vous garantit une flexibilité maximale qui est unique au monde. Les amplificateurs sont la plateforme pour tous les haut-parleurs partout. Comme les amplis, les K2 librairies de haut-parleurs sont conçues avec une précision exceptionelle.

Flexible
-
Compact
-
La construction compacte avec 2UH sur 30 cm de profondeur est probablement un record en compacité et avec 12 kg remarquablement légère. Avec son grand nombre d’écrous à encastrer et les vis super fortes avec vernis de protection, le boîtier solide en tôle d’acier est un bon exemple pour la qualité légendaire des amplificateurs Hoellstern.

5 ans de garantie et une production garantie en Allemagne sont un élément essentiel de la philosophie de nos produits.
Il y a beaucoup d’autres avantages appréciables, mais attention: la devise “hearing is believing“ s’applique. Un test A/B qualifié dit plus que 1000 mots.

1) Each channel provides individually considered extremely high, load stableperformance at nominal impedances down to 2 ohms. The total power of all four channels is at practical burst signals typically 20 kW (40 kW for a short time). Will be permanently accessed more power than the power supply (mains and supply) can provide, so the hardware limiter will reduce the output levels. The hardware limiter should not be used as a signal compressor. It is up to the user to properly deal with the available power pool.
