WISI PROSWITCH
DY 1708 / DY 1716
Multiswitch 17 in x, cascade & stand alone

Cascadable multiswitch for the distribution of 16 satellite polarisations and terrestrial signals
Useable as a stand-alone device (DY 70 power supply required)
Stand-by function with connected power supply, optional permanent operation
Passive terrestrial path to distribute DVB-T/T2, DAB, and FM without an additional amplifier
Integrated SAT amplifier for low insertion loss
Pre-emphasis to compensate for the cable loss at high frequencies
High screening efficiency according to Class A
Stackable chassis for space-saving installation of various devices
Color-coded inputs and outputs

Important Notes:

Please check the coaxial cables regarding the short circuit before starting!
The mounting ground should be:

flame retardant
dust-free
protected against humidity
not under direct impact of sunlight
not adjacent to heating sources

Please check the input level of the SAT lines: They should be nearly equal. All installations and fixings of components should only be executed by skilled people when the units are disconnected from the power source. Short-circuits have to be avoided.
The European and national standards and regulations for the guarantee of electrical security have to be considered as well as the national permissions and legal regulations for broadcast receiving systems! A ground connection must be installed at the device (Ground connector) as well as the satellite dish with at least 4 mm² cables.

**** Grounding and Potential Equalization Pursuant to EN 50 083-1 the satellite antenna system must comply with safety requirements, i.e., grounding and potential equalization.

Application:

This multiswitch is used for the distribution of 16 SAT-IF-Polarizations (e.g. ASTRA, EUTELSAT, Turksat, and Hotbird) from four QUATTRO LNBs and terrestrial signals (passive path).
The selection of the IF-polarization is realized by the control signal 14/18 V (Vertical/Horizontal), 0/22 kHz (Low-, High-Band), and DiSEqC 2.0 by the connected receivers.
The DY types can be powered by the external power supply unit DY 70 or through SAT–trunk lines from connected multi switches or amplifiers (please consider total current consumption). DC-blocks have to be considered to avoid power conflicts.
Not used cascade outputs have to be equipped with DC-blocked terminating 75 Ohm resistors.

Application example:

DC blocked terminating resistor (DV 25)
