Note
– Systems for more than 4 subscribers need be planned with at least one switching matrix EXR 308 (a power supply unit
for remote power feeding to LNBs and the matrices is in the scope of delivery of EXR 308. The matrix is generally
installewd as the final matrix in a distribution system. A through-line matrix EXR 334 is needed for system extension to
another four subscribers.
Example: 16 receivers = 1 x EXR 308 + 2 x EXR 334- Depending on the signal level and the cable loss, it will be
possible to feed the signals to 16 receivers without having to use a Sat matrix amplifier VWS 330.
– Not needed outputs have to be terminated with the resistor type EMK 03 to assure electromagnetic compatibility
(EMC).
– If a matrix system amplifier VWS 330 is used in a system, the LNB and the switching matrices in front of the amplifier
receive the operating power from the power unit of the amplifier. The amplifier and the post-circuited matrices can be
powered either via the switching matrix EXR 308 or via the second DC connection point on the amplifier.
