MULTISWITCHES
MSV504, MSV508, MSV512, MSV516
PRODUCT DESCRIPTION
The multiswitches are designed for use in medium and large size SAT and terrestrial TV distribution systems. The
multiswitches ensure an independent access of every subscriber to any SAT IF or terrestrial line.
The multiswitches are intended for indoor use only.
RoHS compliant.
SAFETY INSTRUCTIONS
Installation of the multiswitches must be done according local safety standards and by qualified personnel.
The multiswitches are powered from the stabilized power supply +18V. This voltage is not dangerous to life.
Any repairs must be done by a qualified personnel.
To avoid damaging of the multiswitch do not connect the supply voltage until all cables have been connected
correctly.
The multiswitch shall not be exposed to dripping or splashing water and no objects filled with liquids, such as vases,
shall be placed on it.
Avoid placing the multiswitch next to central heating components and in areas of high humidity.
No naked flame sources, such as lighted candles, should be placed on multiswitch.
If the multiswitch has been kept in cold conditions for a long time, keep it in warm room no less than 2 hours before
powering.
The ventilation should not be impeded by covering the ventilation openings with items, such as newspapers, table-
cloths, curtains.
Mount the multiswitch in vertical position with RF input connectors on the left side.
From top, front and bottom of installed multiswitch must be at least 5 cm free space.
This product complies with the relevant clauses of the European Directive 2002/96/EC. The unit must be recycled
or discarded according to applicable local and national regulations.

OPERATING
Access to SAT TV lines is controlled by 14/18 V and 0/22 kHz signals, which come from subscriber's receiver through
RF cable. There are 3 gain controls for equalizing the signal level from different lines:
1. For terrestrial TV signal;
2. For High band SAT TV lines (H,Hi; V,Hi);
3. For Low band SAT TV lines (H,Lo; V,Lo).
SAT TV circuits of the multiswitch are powered from the receivers and did not need any external power supply.
Terrestrial TV path is powered through horizontal polarization SAT TV lines (H, Lo; H, Hi). Horizontal polarization lines
inside distribution system are powered from launch amplifier (SA501), but they can be powered from external 18 V power
supply connected to rear side DC connector in the case of installation of single multiswitch.
