Multiswitches
CLASS A
5/24 Multiswitch: Terra MV-524 (IF gain adjustment, class A)
Code: R70724
View of the multiswitch
Top view
Multiswitches from MV series are dedicated for medium and bigger SMATV systems, 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-524 R70724 multiswitch has been equipped with active terrestrial and satellite paths. The levels of DVB-T and satellite signals are set by dedicated switches. This solution assures greater stability than typical adjustments made with potentiometers.
The die-cast housing provides high screening efficiency and prevents penetration of interfering electromagnetic radiation into the unit. High output levels, RF correction and cable length compensation (groups of outputs with different output levels) allow for building large distribution systems with cable runs to individual subscribers up to 80 meters long.
