'''Besonderheiten'''
* MC input
 
  
  
== Remarks ==
 
* All inputs are controlled by relays, therefore very short signal paths.
 
* Symmetrical circuit design from input to output
 
* DC servo system for continuous direct coupling from MC input to output
 
* Pre-amplifier with very wide dynamic range
 
* Both stereo channels are built independently from each other
 
* Brushed solid aluminum front panel and side panels
 
* Computer-controlled controls
 
* Push-button control for input selection
 
* Additional output for active subwoofer amplifier with variable crossover frequency
 
  
 +
== Bemerkungen ==
 +
* Alle Eingänge werden über Relais angesteuert, daher sehr kurze Signalwege
 +
* Symmetrischer Schaltungsaufbau vom Eingang bis zum Ausgang
 +
* Gleichstrom-Servo System für durchgehende Direktkopplung vom MC-Eingang bis Ausgang
 +
* Vor-Vorverstärker mit sehr großem Dynamikbereich
 +
* Beide Stereokanäle sind voneinander unabhängig aufgebaut
 +
• Frontplatte und Seitenblenden aus gebürstetem massivem Aluminium
 +
* Computerkontrollierte Bedienelemente
 +
* Tipptastensteuerung für die Eingangswahl
 +
* Zusätzlicher Ausgang für aktiven Subwoofer Verstärker mit variabler Trennfrequenz
