Fuba FMT 508 Multiswitch 5/8 – Satellite and Terrestrial Signals for Eight Subscribers
The Fuba FMT 508 is a 5/8 multiswitch for distributing the signals of one satellite (4 sat IF bands) and one terrestrial antenna signal to 8 subscribers. Thanks to the integrated 22kHz generator, both quattro LNBs and quattro switch LNBs can be connected to the FMT 508. Control is handled via 13/18V, 0/22kHz, tone and DiSEqC 1.0.
A high output level of up to 92dBµV in the satellite range ensures that subscriber outlets with longer cable runs are reliably supplied as well. The high isolation between the transmission bands (H/V > 25dB) and between the subscriber outlets guarantees consistently high signal quality at every output. The terrestrial signal gain can be adjusted from 0...15dB using the built-in attenuator and therefore matched precisely to the installation.
So that active terrestrial antennas can be connected without additional hardware, the multiswitch offers a switchable remote feed voltage of 0V, 5V or 12V at up to 150mA. The energy-saving power supply with standby function reduces power consumption to 3W when idle, and a status LED indicates the operating state. The FMT 508 is 8K, 4K, UHD, 3D and HD compatible.
