Base unit BS4 Professional

Made in Germany
SAT-Cable Head Station Solution

The TechniNet BS4 Professional is a basis unit for eight TWIN cassettes for professional use. A wide range of applications is possible with this head station, thanks to the eight slots for eight TWIN cassettes, the professional power supply with safety-related features and numerous connection options. An integrated 4/16 multi-switch saves on elaborate cabling inside the basis unit and allows the cards unrestricted access to all four IF levels. Additional separate IF inputs and COFDM inputs (DVB-T) make this system totally flexible. Of course, the system has inputs and outputs for SAT IF signals, so that they can be relayed from basis unit to basis unit in cascade mode.

Operational safety is also very important here. A high-end switching power supply with continuous ventilation ensures sufficient power, while preventing high temperatures and high current loads. Three additional heat-activated exhaust fans are installed in the basis unit. The fans can always deal with any heat build-up caused by the cards and also draw the air out. The basis unit can be controlled using the programming remote control via cable connection. Programming can also be carried out using a laptop via the ethernet connection. At a future date, it will also be possible to use software for remote maintenance of the basis unit. The basis unit is easy to service because the cards can be easily inserted and connected, and the power supply unit can be replaced at any time using a slide-in compartment. The basis unit can be secured against unauthorised access at any time using its locking front cover.

The wall mounting hardware supplied makes it possible to:

1. Mount the basis unit on a wall
2. Mount the basis unit in a 19" rack

HDTV stands for High Definition Television, thus for outstanding picture quality. With HDTV, pictures can be displayed in much greater detail and with much finer gradations. Contrast and contours are more precise and colours truer to their originals. Furthermore, the wide screen format on HDTV broadcasts corresponds much better to human visual perception. So it creates a more vivid impression overall.
