Alcad MU-341 Cascadable multiswitch, 9x8 actif

Alcad MU-341 - Serie 913: Cascadable multiswitch, 9x8 actif.

Multiswitches for 8 and 16 polarities and terrestrial TV with 8 or 16 outputs, for installations in cascade. The inputs of the 8 polarities and the terrestrial TV are amplified. For 16 polarities, 2 stacked multiswitches of 8 polarities are installed and an external DiSEqC switch (CN-611) for each output. The tap outlets are amplified on the IF satellite band. Power must be supplied from the inputs or the through outputs to feed the built-in line amplifiers. Power must be supplied from each individual receiver to feed the switching and amplification of each tap output. To feed the active multiswitches, the FU-513 power unit is used; it is connected to the AU-620 amplifier of the cascade.

Applications

Medium-sized to large MATV and SMATV installations. Enables distribution to up to 128 TV outlets in a single line, with power supplied only at the head-end of the cascade. By dividing the installation into lines of 128 outlets and distributing the 8 polarities and the terrestrial TV to all the lines, it is possible to reach more than 2,000 outlets. Distribution in cascade from the first multiswitch, with 9 coaxial cables between multiswitches and a single coaxial cable to each TV outlet. For each outlet, the multiswitch distributes a satellite polarity as well as the terrestrial TV. For 8 polarities, the polarity is selected from the individual receiver using the LNB control signals and tone burst or using the DiSEqC signals (version 1.0 or higher); for 16 polarities, polarity is selected using only the DiSEqC signals.

Characteristics

Return path included from 5 to 65MHz. Shielded zamak chassis with plastic supports. F-type connectors. Distances of more than 75m between multiswitch and outlet. Up to 100 terrestrial TV channels.
