Die STUDER A807 zählt mit Sicherheit zu den  am meisten verkauften Produkten aus dem Hause STUDER. Weltweit wurden über 10.000 (!) Einheiten verkauft. Die A807 wird vor allem den vielen Rundfunkanwendern weltweit in guter Erinnerung sein und bleiben. Zumindest für die nächsten Jahre ist auch die Ersatzteilbeschaffung garantiert gesichert wie mir persönlich von einem STUDER Techniker auf telefonische Anfrage versichert wurde...

A STUDER A807 can be calibrated easily and relatively fast to the desired values. To do this, you need a pointed object such as a ballpoint pen refill. Carefully insert it into the small opening marked "Adj". The button in the opening automatically switches to the calibration mode. Now you can determine the desired values. The buttons "Lap", "Set" and "Sel" are now used to select the different modes. The buttons "Loop" and "Loc Start" are now used for value selection. With the button "Step" the changes are stored afterwards. The menu can be exited by pressing the "Adj" button. Further information on this topic can also be found in the manual.

Der kompakte Aufbau der A807 macht diesen Rekorder zum idealen Arbeitsmittel im Rundfunkbereich, egal ob stationär oder mobil. Das Laufwerk basiert auf einem robusten Aluminium-Druckguss-Chassis. Direktantreibende, servogesteuerte Wickelmotoren mit hohem Drehmoment garantieren sowohl hohe Wickelgeschwindigkeiten als auch rasches Beschleunigen und Abbremsen. Capstanantrieb mit bürstenlosem Präzisions-DC-Motor für rasches Hochlaufen und synchronisieren. Dazu kommt:  Mikroprozessorgesteuerte Laufwerk- und Audioelektronik, drei Bandgeschwindigkeiten, Shuttle-Rad für einfaches Rangieren, und die serienmäßige Ausstattung mit paralleler und serieller Schnittstelle (RS232); phasenkompensierte, digital gesteuerte Audioelektronik - ohne Abgleichpotentiometer; Versionen mit eingebauter 48 V-Mikrofon-Phantomspeisung (12 V Phantomspeisung als Option), 300 mm Wickelteller mit 1000m Band und ein breites Angebot an Zubehör: Laufwerk-Fernsteuerungen, Varispeed-Controller, Transportkoffer und Transporthilfsmittel, Studiokonsolen und verschiedene Aufbauten.

===Studer A807 Einmessen===
+
== Reviews ==
−
Eine STUDER A807 lässt sich ganz einfach und relativ schnell auf die gewünschten Werte einmessen. Dazu benötigt man einen spitzen Gegenstand wie z.B. eine Kugelschreibermine. Diese führt man vorsichtig in die kleine Öffnung mit der Bezeichnung "Adj" ein. Der in der Öffnung befindliche Taster schaltet dann automatisch in den Einmessmodus um. Nun kann man die gewünschten Werte bestimmen. Die Tasten "Lap", "Set" und "Sel" dienen nun für die Auswahl der verschiedenen Modi. Die Tasten "Loop" und "Loc Start" werden nun zur Wertauswahl genutzt. Mit der Taste "Step" werden die Änderungen anschließend gespeichert. Das Menü verlässt man wieder über einen Druck auf die Taste "Adj". Weiterführende Informationen zu diesem Thema befinden sich auch im Manual .
