„DIN rail“ products

Products have compact modular die-cast casing and are mounted on the wall or on standard "DIN” rail. Modulator and amplifier are powered from external 12 V power supply and may transfer power supply to other amplifiers and modulators over special flat cable. Products can be used as stand-alone or as system components.


DVB-T modulator mdx420 encodes standard definition analogue audio/video signals to MPEG2 transport stream and modulate its RF signal. DVB-T modulator mdx420 forms single 7 or 8 MHz bandwidth DVB-T RF channel in the output. Analogue composite video signal may be of PAL/SECAM/NTSC standard. User can change program names, encoding bit rate, audio level, video format and other parameters. mdx420 is managed using joystick and buttons. Parameters are represented on a high contrast OLED screen.

Selective double TV amplifier at422 amplifies analogue and DVB-T TV signals, stabilizes level in 174–230 MHz VHFIII range. It efficiently filters outlying unwanted signals.
Data sheet
Selective quadruple TV amplifier at440 amplifies analogue and DVB-T TV signals, stabilizes level in 470–790 MHz UHF range. TV amplifier input has additional integrated LTE signal filter.
Data sheet
In at422 and at440 amplifiers TV channel may be set in all operational frequency range. Due to the latest SAW filters the amplifiers are especially selective. Fine tuning +/-1 МHz with 125 kHz step allows to significantly increase the attenuation of unwanted signals in the neighboring upper or lower channel. User on a software level can turn off every section of an amplifier, switch 12 V antenna amplifier power supply in RF input, set attenuation in the output of every section up to 10 dB with a step of 1dB. Installed AGC system ensures stable output signal level. Front panel of the amplifier includes three control buttons and two 7 segment indicators.


12 V output voltage power supply unit UP410 powers modules of multiband station. UP410 has three 12 V output connections - two for special flat cable and one reserve connection with clips.
