Multiswitches
CLASS A
5/16 Multiswitch: Terra MV-516 (IF gain adjustment, class A)
Code: R70716
View of the multiswitch
Top view
Multiswitches from MV series are dedicated for medium and large SMATV systems with distribution of SAT IF and terrestrial TV signals, however they can also be used in smaller installations.
Distinguishing features
- radial structure
- built-in compensation of cable attenuation
- groups of outputs with different output levels
- isolation between outputs better than 30 dB
- active terrestrial path
- die-cast housing provides high screening efficiency (class A)
The MV-516 R70716 multiswitch has got built-in amplifiers for terrestrial and satellite TV. The adjustment of the SAT IF and DVB-T gain is made with dedicated switches. In comparison with potentiometers, this solution increases stability of the adjustments.
The die-cast housing provides high screening efficiency by preventing the penetration of interfering signals to the unit. The high maximum output level and compensation of the attenuation caused by coaxial cables, plus outputs with graded signal levels - allow for building large systems with cable runs up to 80 meters (between outputs and subscriber outlets).
