Description
SE EDITION WITH ~15dB IMPROVED SHOULDERS IS OUT
CYBERMAXFM+ BE DAB+ TRANSMITTERS
These are our DAB+ digital radio transmitters. Each transmitter is housed in 2H or 3H rack enclosure. They consist of EDABv2+ DAB+ SE digital radio exciter board and RF amplifier designed specifically for digital radio. Equipped with large new OLED display and LED bar graph meters! Based on our new control board. These units in large 2H or 3H rack enclosure contain amplifiers which give 20W, 400W or 800W of DAB+ RF power 24/7/365. Large heavy-duty ball-bearing cooling fans with automatic speed control take care of any excessive heat at minimal noise level. Amplifier is equipped with SWR and temp protection and remote control via Ethernet. A robust amplifier made for 24/7/365 operation. DAB+ exciter is controlled and configured via web interface. The amplifier is also configured and controlled via web interface on another IP address. Audio is supplied via ETI-stream which is created via ODR-DabMUX and fed in through Ethernet.
Black edition with new high performance advanced display
– Bright 122×32 graphical LCD with rotary encoder, USB and Ethernet ports.
– Remote control via Ethernet via web browser as standard, possible even from mobile phone
– Built-in scheduler can change power 2x per day to any preset value you desire. Independent of any PC.
– Time update via Internet to always ensure precise time.
– Firmware of all sub-systems can be upgraded via USB interface. If we release an update or a new feature you will be able to install it.
– Calibrated two-color VU meters for power, reflected power
– 100 power adjustment steps
– Percentage based power adjustment (50% will now give approximately half of output power, V2 could give very approximate result)
Please note: It is recommended that you first evaluate the product by trying our DAB+ exciter. This way you will learn to use and configure software and also establish whether this DAB+ solution is suitable for your needs.
Manuals and drivers for most products are available under the Additional Information tab above, just under the prices. Some old manuals are here.
If your web browser blocks the download, you may have to allow it manually.
What parameters can I change or monitor via remote control?
Output power, various alarms, network parameters, time settings can be changed via Ethernet in web browser. No software installation is needed, just connect your transmitter to local Ethernet and open web browser to access all the settings. Check the manual for more info. Below is a small sample of the interface.
Technical specifications for amplifier:

Important:
Requires ETI stream (computer running ODR-DabMUX somewhere connected to Internet or Ethernet). The audio is fed to this computer and it is this computer that creates the ETI stream. This computer can be anywhere connected to Internet, even on the other side of the world thousands of km far from DAB+ card.
How do I setup DAB+ radio?:
Step-by-step instructions are here: https://wiki.opendigitalradio.org/RaspDA
The exciter itself is configured via WEB interface (enter the IP address of the DAB+ exciter into web browser).
QFN network upgrade
– The card is equipped with a few hardware modifications and is superior to standard card. You can use it also when you don’t want to use the SFN function.
– With correct version of firmware both on the exciter card and ODR-DabMUX it is possible to run in SFM mode.
WHAT ELSE WILL I NEED AND IT WASN’T INCLUDED?
– Audio is supplied via ETI-stream which is created via ODR-DabMUX and fed in through Ethernet. You can receive this ETI stream from other sources or you can create it yourself. You will have to dedicate some time and computer knowledge to learn how to do this.
– Requires mains plug which can be purchased in your country (each country
has a different mains plug and we don’t carry all). This is standard mains plug and its price is typically around 1 US$ or less. You
can get it in any electronics store, such as radio shack, circuit city, any
computer store etc. Always use grounded plug for your safety!
– You will also need antenna
– You will also coaxial cable to connect antenna HERE.
