schaltet. Dies ist normal und bedarf keiner †berprŸfung. Es kann auch sein, da§ der VerstŠrker sich abschaltet. Dies ist der Fall wenn nicht genŸgend frische Luft angesaugt werden kann oder die Ventilation zur Vorderseite behindert wird. In diesem Fall geht die POWER LED auf der Vorderseite des GerŠtes aus. Eine †berprŸfung der šrtlichen Begebenheiten in Bezug auf Luftzufuhr und KŸhlung sollte unbedingt stattfinden, wenn sich das GerŠt mehrmals auf Grund von †berhitzung abschaltet. Generell gilt: Je kŸhler das GerŠt, desto lŠnger die Dauer der LeistungsfŠhigkeit.

BRIDGE MODE

Wie erwŠhnt ist der BRIDGE MODE nicht empfehlenswert fŸr Installationen, wo der VerstŠrker in gro§em Abstand zu den Lautsprechern steht. Die CA-A540 und CA-A800 VerstŠrker sind

dennoch mit einem Schalter versehen, der es erlaubt, den BRIDGE MODE zu benutzen. Der Anschlu§ wird Ÿber die beiden Ò+Ó Pole der Outputs vorgenommen, Input ist Kanal A. Kanal B wird automatisch abgeschaltet. Die Impedanz mu§ mindestenz 8 Ohm betragen.

SPS OPERATION

PeaveyÕs patentierter SPS Kompressor / Limiter schŸtzt das System vor clipping unter Vollast. Diese Schaltung erkennt Signalspitzen bevor Sie den VerstŠrker Ÿbersteuern und schwŠcht sie ab. Bei normalem Betrieb bleibt die Schaltung abgeschaltet. Bei der ÒnormalenÓ Installation in Kinos und Theatern wird empfohlen, da§ die Schaltung auf ENABLE steht.
