OMB EM 5000 DDS

The OMB EM 5000 DDS 5000W fully digital FM transmitter has been created by the OMB center of development for DDS technology. Thanks to its powerful core, crystal clear sound, accurate
filtering procedures, audio processing and usage this device brings your experience to the next level. This 5000W DDS FM transmitter comes with a 4.3” touch screen display, allowing an
easy configuration and simple access to functions setting, operating parameters and alarms detections. It also includes a wide mode AES/EBU (192kHz broadband sampling), audio
backup and many more advanced features. Its high efficiency 5KW amplifier has an approximate consumption of 6600VA at 230Vac, so it pays for itself in a short period of time due to its low consumption.

FEATURES

– Typical AC efficiency >73% and typical RF efficiency of 84%.
– Six amplifying modules of 1.200W with robust LDMOS transistors of the latest technology.
– Three independent switching power supplies connected in parallel to maintain the equipment working in case
any of them fails.
– TFT screen and touch keyboard to control and to visualize operation parameters.
– Memory recording of events.
– Speed control of cooling fans according to temperature of power modules so as to optimize consumption and
to decrease acoustic contamination.
– Advanced protection against load mismatches without transmission cuts and fast protection in case of
excessive reflected power and/or excessive input power.
– Analog telemetry, digital remote control and telemetry RS232, remote control by opened/closed contacts.
– Low pass filter, Mains EMI filter and internal single-phase transient suppressor.
– Automatic power reduction at night when used in combination with the EM 50 DDS transmitter.
– Automatic power reduction in case of high temperature, the equipment returns automatically to its rated power
value when the temperature reaches back an average value.
– Automatic power reduction in case of excessive reflected power.
– Suitable for single frequency applications (SFN), audio limiter (ITU).
– Audio rescuer integrated, with programmable established time and all inputs priority (analog, digital and MPX).
– Programmable power reduction.
– Automatic voltage control for efficiency optimization.
