DC fault

protection

The outputs will mute if DC or excessive subsonic energy appears at them.

Input/output protection

The input circuits are isolated by 10ký resistors. An ultrasonic network decouples RF from the outputs and helps keep the amplifier stable with reactive loads.

Protection contre une

anomalie CC

Les sorties seront coupées en

présence de courant continu ou de signal subsonique excessif.

Protection entrées/ sorties

Les circuits d’entrée sont isolés par des résistances de 10ký. Un circuit ultrasonique découple les RF (Radio Fréquences) des sorties et aide à maintenir la stabilité de l’amplificateur sous des charges réactives.

Schutz gegen

Gleichspannung

Bei Auftreten von Gleichspannung oder übermäßigem Störpegel im Infraschallbereich werden die Ausgänge stummgeschaltet.

Eingangs-/ Ausgangsschutz

Die Eingangsschaltungen sind mit 10ký- Widerständen isoliert. Ein Ultraschallfilter entkoppelt Hochfrequenz von den Ausgängen und stabilisiert die Ausgangsschaltkreise gegen rückwirkende Störpegel oder Störspannungen.

Protección contra

corriente continua

Las salidas se enmudencerán si hay demasiada corriente continua o energía subsónica en ellas

Protección enterada/ salida

Las entradas están aislidas a través de resistencia de 10ký. Una red ultrasónica elimina la radiofrecuencia de las salidas y ayuda al comportamiento estable del amplificador con cargas reactivas.
