ACHTUNG: Um die Gefahr eines Brandes oder Stromschlags zu verringern, soll-

ten Sie dieses Gerät weder Regen noch Feuchtigkeit aussetzen.Um die Gefahr eines Stromschlags zu verringern, sollten Sie weder Deckel noch Rückwand des Geräts entfernen. Im Innern befinden sich keine Teile, die vom Anwender

gewartet werden können. Überlassen Sie die Wartung qualifiziertem Fachpersonal.Der Blitz mit Pfeilspitze im gleichseitigen Dreieck soll den Anwender

vor nichtisolierter “gefährlicher Spannung” im Geräteinnern warnen. Diese Spannung kann so hoch sein, dass die Gefahr eines Stromschlags besteht. Das Ausrufezeichen im gleichseitigen Dreieck soll den Anwender auf wichtige Bedienungs- und Wartungsanleitungen aufmerksam machen, die im mitgelieferten Informationsmaterial näher beschrieben werden.

Wichtige Sicherheitsvorkehrungen

1. Lesen Sie alle Anleitungen, bevor Sie das Gerät in Betrieb nehmen.

2. Bewahren Sie diese Anleitungen für den späteren Gebrauch gut auf.

3. Bitte treffen Sie alle beschriebenen Sicherheitsvorkehrungen.

4. Befolgen Sie die Anleitungen des Herstellers.

5. Benutzen Sie das Gerät nicht in der Nähe von Wasser oder Feuchtigkeit.

8. Bauen Sie das Gerät nicht in der Nähe von Wärmequellen wie Heizkörpern, Wärmeklappen, Öfen oder anderen Geräten (inklusive Verstärkern) ein, die Hitze erzeugen.

9. Setzen Sie die Sicherheitsfunktion des polarisierten oder geerdeten Steckers nicht außer Kraft. Ein polarisierter Stecker hat zwei flache, unterschiedlich breite Pole. Ein geerdeter Stecker hat zwei flache Pole und einen dritten Erdungsstift. Der breitere Pol oder der dritte Stift dient Ihrer Sicherheit. Wenn der vorhandene Stecker nicht in Ihre Steckdose passt, lassen Sie die veraltete Steckdose von einem Elektriker ersetzen.

10. Schützen Sie das Netzkabel dahingehend, dass niemand darüber laufen und es nicht geknickt werden kann. Achten Sie hierbei besonders auf Netzstecker, Mehrfachsteckdosen und den Kabelanschluss am Gerät.

11. Ziehen Sie den Netzstecker des Geräts bei Gewittern oder längeren Betriebspausen aus der Steckdose.

12. Überlassen Sie die Wartung qualifiziertem Fachpersonal. Eine Wartung ist notwendig, wenn das Gerät auf irgendeine Weise, beispielsweise am Kabel oder Netzstecker beschädigt wurde, oder wenn Flüssigkeiten oder Objekte in das Gerät gelangt sind, es Regen oder Feuchtigkeit ausgesetzt war, nicht mehr wie gewohnt betrieben werden kann oder fallen gelassen wurde.

WARNING: To reduce the risk of fire or electric shock, do not expose this unit to rain or moisture. To reduce the hazard of electrical shock, do not remove cover or back. No user serviceable parts inside. Please refer all servicing to qualified personnel.The lightning flash with an arrowhead symbol within an equilateral triangle, is intended to alert the user to the presence of uninsulated "dangerous voltage" within the products enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. The exclamation point within an equilateral triangle is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompanying the product.

Introduction

S 2-way Features

The Samson S 2-way electronic crossover utilizes the latest technology in crossover filters and speaker management design. Here are some of its main features:

• Full featured, Stereo 2-way, Mono 3-way electronic crossover.

• Precision Linkwitz-Riley, 24 dB/Octave filters.

• Each channel incorporates a High Pass Filter, Butterworth 25 Hz, 12 dB/Octave, to help you reduce stage rumble and the engery loss from sub-sonic frequencies.

• For time aligning speaker stacks, each Low Frequency output can be delayed for phase correction by using the adjustable Delay control located on the front panel.

• The X10 Range switch allows to adjust frequency range of the filter, allowing you to change from mid-band to high-band.

• The four segment LED Input Gain meter allows you to monitor the signal level and make easy gain adjustment.

• In the Master Control Section, there is a Mute switch for each of the individual outputs, allowing you to listen to the different sections of the speaker systems seperately.

• Phase Switches are included in the Master Control Section to invert the phase of the individual outputs.

• Servo balanced inputs and outputs on XLR connectors.

• Pristine audio quality thanks to the advanced circuit design, utilizing low noise operational amplifiers and high quality VCAs.

• High quality metal shaft pots and backlit switches.

• The stylish, electric blue, alluminum front-panel is as easy to read as it is to look at.

• Three-year extended warranty.
