Thermal protection

A variable-speed fan provides adequate cooling air flow. However, if the heatsink temperature should climb above 90° C, the outputs will mute until the amplifier cools down.

DC fault protection

The amplifier will shut down if DC or excessive subsonic energy appears at the outputs.

Input/output protection

The input circuits are isolated by resistors. An ultrasonic network decouples RF from the outputs and helps keep the amplifier stable with reactive loads.

Protection thermique

Un ventilateur à vitesse variable fournit le courant d’air nécessaire au refroidissement de l’amplificateur. Si la température du radiateur devait dépasser 90° C, les sorties seraient coupées jusqu’à ce que l’amplificateur ait suffisament refroidi.

Protection contre une

anomalie CC

L'amplificateur sera éteint en présence de courant continu ou de signal subsonique excessif aux sorties.

Protection entrées/

sorties

Les circuits d’entrée sont isolés par des résistances. Un circuit ultrasonique découple les RF (Radio Fréquences) des sorties et aide à maintenir la stabilité de l’amplificateur sous des charges réactives.

Thermische

Schutzschaltung

Ein drehzahlgeregelter Lüfter sorgt für kühlenden Luftstrom. Falls die Kühlkörper dennoch über 90° C erhitzt werden, werden die Ausgänge bis zum Erreichen einer sicheren Betriebstemperatur stummgeschaltet.

Schutz gegen

Gleichspannung

Beim Auftreten von Gleichspannung oder übermäßigen, tieffrequenten Signalen (Infraschall) an den Ausgängen, schaltet sich das Gerät selbständig ab.

Eingangs-/

Ausgangsschutz

Die Eingangsschaltungen sind mit Widerständen isoliert. Ein Ultraschallfilter entkoppelt Hochfrequenz von den Ausgängen und stabilisiert die Ausgangsschaltkreise gegen rückwirkende Störpegel oder Störspannungen.

Protección térmica

Un ventilador de velocidad variable proporciona el flujo de aire adecuado para le refrigeración. Si la temperatura del radiador sube por encima de los 90° centígrados, las salidas se enmudecen hasta que el amplificador se enfría.

Protección contra

corriente continua

El amplificador cortará si hay corriente continua o demasiada energía subsónica en las salidas.

Protección entrada/

salida

Las entradas están aislidas a través de resistencia. Una red ultrasónica elimina la radiofrecuencia de las salidas y ayuda al comportamiento estable del amplificador con cargas reactivas.
