Block diagram
Der Verstärker hat im Grundausbau 3 elektronisch symmetrische Eingänge, 1,2 und 3 für dynamische Mikrofone.
Der symmetrische Eingang 6 mit Limiter ist für dynamische Mikrofone verwendbar. Er ist mit dem Eingangsverstärkerbaustein -L934 ausgestattet.
Dieser Eingang hat Vorrang gegenüber allen anderen Eingängen. Wird dieses Mikrofon (mit einer Kontrollspannung von 0 V) aufgeschalten, werden alle anderen Eingänge weggeschaltet.
Die Eingänge 4 und 5 können mit den optionellen Eingangsverstärkerbausteinen -L930, -L931, -L934, -L939 als Mikrofoneingänge oder als erdfei symmetrische Hochpegeleingänge verwendet werden.
Eingang 6 hat Priorität gegenüber den Eingängen 1 bis 5 (abschaltbar mit Brücke X105).
Mit dem Universalverstärker mit Schwellwertschalter kann eine ferngesteuerte Durchschaltung mit Priorität realisiert werden. D.h. sobald ein am Eingang 6 ankommendes NFSignal einen einstellbaren Pegel überschreitet, werden alle anderen Eingänge abgeschaltet und dieses NF-Signal wird durchgeschaltet. Unterschreitet das ankommende Signal die Schaltschwelle so werden nach Ablauf einer einstellbaren Abfallzeit wieder alle Eingänge eingeschalten. Für dieser Funktion muß der Pin 10 des Bausteines mit dem Pin X213 auf der Grundplatine über ein kurzes Kabel verbunden werden.
Die 3 unsymmetrischen Line-Eingänge, 1,2 und 3 sind für diverse hochpegelige Tonquellen (mit 0 dBu - wie z.B. CDPlayer, Kassettenrecorder) verwendbar.
Die Eingänge 4 bis 6 können mit optionellen Eingangsverstärkerbausteinen als erdfei symmetrische Hochpegeleingänge verwendet werden.
Optionelle Eingangsverstärkerbausteine: -L930, -L932.
In its basic complement, the amplifier features 3 electronically balanced inputs (1,2 and 3) for dynamic microphones.
The balanced input 6 with limiter can be used for dynamic micropones. It is equipped with the input amplifier module -L934
This input has prioriry against all others. If this micropone is switched on (with a control voltage of 0 V) all other inputs will be switched off.
If inputs 4 and 5 are equipped with the optional input amplifier modules –L930, -L931, -L934, -L939, they can be used as microphone inputs or as floating, balanced highlevel inputs.
Input 6 has priority over inputs 1 to 5 (deactivated by jumper X105).
The universal amplifier with threshold point switch makes it possible to perform remote-controlled routings with priority switching. This means that as soon as an AF signal arriving at input 6 exceeds a preset level, all the remaining inputs are switched off and the incoming AF signal is throughconnected. If the incoming signal remains under the switching threshold, all the inputs are switched back on after a preset fall time. To enable this function, pin 10 of the module must be connected to pin X213 of the PCB via a short cable.
The three unbalanced line inputs 1, 2 and 3 can be used for various high-level sound sources (at 0 dBu; e.g. CD player, tape recorder).
When equipped with the optionally available input amplifier modules, the inputs 4 to 6 can be used as floating balanced high-level inputs.
Optional input amplifier modules: -L930, -L932.
