Operating manual
WISI PRO SWITCH
DY 40
Line amplifier 4x SAT-IF

4 SAT polarizations in a compact form factor
30 dB gain
Independent attenuation of 0…19 dB per input
Selectable pre-equalization to compensate for frequency depending on cable loss
Simple extension up to 16 polarizations
High screening efficiency of Class A
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.
Note: Tighten the F connector to approx. 4 Nm.
Grounding and Potential Equalization Pursuant to EN 60728-11 the satellite antenna system must comply with safety requirements, i.e., grounding and potential equalization.
Application:
The DY 40 is used for the amplification of four SAT-IF polarizations of one satellite. By easy combining expandable up to 16 SAT-IF polarizations of four satellites.
The amplification is 30 dB and can be decreased between 0…19 dB. The setting is done by the integrated buttons and can be adjusted at each input independently.
The DY 40 allows the pre-equalization of the SAT signals. Especially in huge distribution networks is this a big advantage to compensate the cable loss on higher frequencies. The pre-equalization can be adjusted to 0, 4, 8, and 12.

DC IN
The power supply of DY 40 and the connected LNB.
DC out
Power supply of further connected DY 40. Power supply trunk “up”
Switch mode “up”
The voltage of the connected power supply will be forwarded only to the LNB.
Switch mode “up+down”
The voltage of the connected power supply gets forwarded to the LNB and subsequently multi- switches and amplifiers.
Quick connectors
All devices of the PRO SWITCH series can be combined by using quick connectors (DV 49A).
