Product discription:
DAB+ 400W digital radio zender
Each transmitter is housed in 2H or 3H rack enclosure. It consists from EDABv2+ DAB+ digital radio exciter board and RF amplifier designed specifically for digital radio.
Equipped with large 4x16 LCD display and LED bargraph meters! Amplifier section is controlled with our new control board. Power is measured with our new directional couplers with true-RMS response, perfect for DAB+ Large heavy-duty ball-bearing cooling fans take care of any excessive heat. Amplifier is equipped with SWR and temp protection and features PC remote control (possible via USB, RS232 or Ethernet). A robust transmitter made for 24/7/365 operation. DAB+ exciter is controlled and configured via web interface. Audio is supplied via ETI-stream which is created via ODR-DabMUX and fed in through Ethernet.
What parameters can I change and monitor via PC remote control?
- Power (100 steps)
- Alarms
- Temperature, output power and reflected power, voltage
- You can put unit into stand-by
- You can monitor current and voltages, two temperatures, output and input power and also reflected power
