Black edition with new high performance advanced display, backed by 5 years of warranty
The new Black Edition (BE+) series FM exciter brings completely new advanced graphics display with many new features such as web control interface, ethernet connectivity, two-color VU meter, smooth rotary button operation and full control over every aspect including RDS. Sharp low pass filter, great stereo separation, fantastic reliability and tight MPX control with several limiters were carried over from the previous models. With this new OLED display and new great looking enclosures with improved ventilation it seemed completely logical that warranty period would be extended to 5 years **.
This unit is perfect for demanding broadcasters. No tuning is necessary, design is entirely wideband. All you have to do is set the frequency and output power, the rest is optional. SWR, temperature and polarity protection make it difficult to destroy the unit. Unit is housed in a brand-new 1H professional 19″ rack, new design is lighter and RF tight (does not leak RF). It is rugged and made for 24/7/365 operation. Each unit has a wide-angle high contrast OLED display.
Those who use streaming sources to stream your audio will be happy to hear that as an option we also offer industry – standard streaming service receiver which also reads MP3 files from USB port at the back. What is even cooler is that the name of the stream or song name (if transmitted by stream operators) will be displayed on the display and also sent out with RDS. Instructions how to set this up are in the manual for the LCD display.

DISADVANTAGES
Hardly any
RANGE AND POWER SELECTION
Exact range depends a lot on terrain configuration, type of antenna and especially the location of the antenna and of course quality of receivers. Even 1W is often enough for drive-in cinema but sometimes there could be interference sources and overpowering them can require more power. 15W is a good selection with 25W giving you extra piece of mind. Sometimes you just need more power and 50W definitely gets the job done. You can set power anywhere from zero to max with LCD display/keys, there are 100 steps. Even 100W transmitter can be set down to 1W.
BE SAFE, GET A BACKUP
Our transmitters are very reliable but something can always go wrong. Ever dropped something? Spilled coffee over keyboard? A backup system, even if at 1W only, can save your face and keep your customers satisfied even if the unthinkable happens. Once your customers start rolling in you will be very glad you have a backup.

How do I wire up the transmitter, antenna and audio sources?
Look at the image below (click to enlarge) for an example of a nice radio station with some studio items. At the bottom of this page look for the links to other items that you can use to setup your radio station (WHAT ELSE WILL I NEED AND IT WASN’T INCLUDED? and WHAT CAN I USE AS AUDIO SOURCE?).
What parameters can I change via remote control?
Frequency, output power, various alarms, network parameters, time settings, audio input selection and levels, DSP parameter and RDS 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.
What is RDS?
Radio Data System, basically it displays station name and sometimes song name and similar information on a compatible radio receiver. Very popular in Europe, less so in the US. Requires connection to a PC at the time of programming, but retains settings even when powered off. RDS requires RDS upgrade option so be sure to add it, if you need it.
IP audio streaming with MP3 playout from USB
This add-on card lets you receive internet audio streams or play MP3 files from USB drive. This is basically industry-standard Barix IP module inside your transmitter. Especially cool is that the stream source often also transmits song name and when this is the case the RDS encoder can also transmit song name and it can be displayed on the LCD. Read the manual to see how this is done.
Basic Studio (mixer and microphone)
Save yourself some time and get studio package as well. Basic studio package includes:
– 8-channel Behringer mixer (8 channels, 2 mic inputs with compressor, USB audio interface)
– Studio microphone with cable
– Microphone stand
Need more studio gear?
Need audio processor? Check these.
Need a link from studio to the transmitter site? How about these.
Important: Due to large size and irregular shape of these packages the website often gets shipping cost wrong. For exact shipping cost please contact our sales department, be sure to give them your exact address and they will quote you shipping. It also does not hurt to ask for a special discount.
Also recommended: We recommend AA-230 antenna analyser for checking SWR of the antennas. Grounding kits can be purchased here, they ensure lightning protection. They should be installed at the antenna (if needed, most dipoles are grounded anyway), at the tower base and at the point of entrance into transmitter building. Also use self-sealing tape which turns into rubber and protects against moisture from entering your connectors and coaxial cable.
WHAT CAN I USE AS AUDIO SOURCE?
– Your PC. Just plug audio cable into your sound card.
– CD player, MP3 player or any other music reproduction system
– Mixing board with microphone and other audio gear
WHAT ELSE WILL I NEED AND IT WASN’T INCLUDED?
– Requires mains cable, which can be purchased in your country (each country has a different mains plug and we don’t carry all). This is standard cable used in your PC for example 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. Mains cable simply plugs into the transmitter, just like it does with your PC, there is no soldering involved.
– Good taste for music and great skill to put together a program that will dazzle your listeners
