T.0X Transmodulator with remultiplexing DVBT, DVBS / S2 COFDM CI TWIN by Televes
Transmodulator 564301 with remultiplexing COFDM
This transmodulator receives the signal of 3 transponders, of which at least two must be of the same polarity and band, and can generate two muxes with content from any input transponder.
If in your case you use a CAM for the decryption of services, it can be located just off of one of the demodulators or position it in the transport multiplex. This transmodulator also has a function that prevents DCY INSURANCE CAM overflow in case of appearance of new PID.

What are the main features of the Televes 564301 transmodulator?
It allows the installer, in addition to configuring the services to the exit, to eliminate a concrete PID of some of the services.
Configurable and remotely monitorable through CDC.
They provide useful rate information for each of the input services, showing the occupation of the output channel.
TWIN output signal fully configurable (2 muxes).
DiSEqC.
Configurable CAM position.
LCN and combined SID issue on both muxes that prevents TV retune when updating the channel grid.

Year Warranty *Special Order! NCNR – Check Lead Time* This unit can be used as a cascade element
since it has 13 outputs to connect to other switches and increase the number
of users. This range of products has been designed with the ECO system: as
the number of users decreases, the power consumption of the system will
decrease as well. Gain in the FI band can be selected individually for each
group of 8 users to provide a balanced output. -

Year Warranty *Special Order! NCNR – Check Lead Time* Part of the range of 9 input multiswitches
(8 satellite polarities + Freeview), available in 8, 12, 16, 24 and 32 user
outputs. Expand the number of users by cascading two or more units. Small and
compact design to provide an easy and quick installation. The range includes a 9x line amplifier with
25 dB average gain for Satellite inputs and 27 dB gain for Terrestrial with
DC pass. 75 ohms switch included to
load the unit (standalone) or not (cascade configurations). Highlights: Radiation immune thanks to its
zamak made chassis. All switch references are valid for standalone, star or
cascade configuration. Selectable IF gain (+10 dB) for each group or 8 users
to balance the output signals. Multiple powering options: mains and line
powered. ECO mode: the overall consumption is reduced as the number of users
decreases. Main features: Small sized
design: Make the most of space to accomodate more TV subscribers. Use the
same multiswitch in either star/cascade or standalone configuration.
Independent amplification of every feed (8 satellite plus Freeview). Multiple
powering options: mains and line powered. Adjustable gain and equalization to
achieve the best performance for every system’s requirements. -

Year Warranty *Special Order! NCNR – Check Lead Time* Compact multiswitch equipped with 9 inputs
(one terrestrial and 8 for two satellites, each with its four polarities) and
32 user outputs. Thanks to its great
compactness and its optimized electronic design, it presents very low through
and tap losses. This allows to reduce the number of amplifiers needed in the
cascade and to obtain a better balanced signal in the users, even in large
collective installations. Can be used
as a terminal (star topology) or as a cascade by using a simple switch. In
addition, it incorporates a second switch that actives the TForce technology,
which automatically adjusts the terrestrial signal and keep it constant
despite variations in the reception. RED compliant Main Features: High shielding (A class) thanks to its
manufacture in Zamak Versatile: selector switch to shift between cascade and
terminal modes Low consumption under normal conditions. In addition, ECO mode
reduces consumption as the number of connected users decreases Wide 12-18V
power supply range, making it compatible with most existing systems Current
