Description

15W, 25W, 50W and 100W FM TRANSMITTER PACKAGES FOR DRIVE-IN CINEMA AND Simultaneous Interpretation!

Can also run off the batteries (12-15V), practical for mobile or solar powered installations

These packages are based on our CyberMaxFM+ SE V3 rack-mounted FM transmitter series, designed for demanding broadcasters operating in the 87.5 to 108 MHz band. They include our reliable FM transmitter with optional DSP stereo and RDS, an antenna, coaxial cable, and all necessary connectors. This versatile FM transmitter is ideal for various applications, including licensed radio stations, drive-in cinemas, simultaneous interpretation, church radio, medium-sized radio stations, campus radio, and religious radio. It is also well-suited for portable or improvised installations, small radio stations, advertising (housing, shops), special occasions, drive-in cinema wireless sound distribution, translation, and tourism. The unit features temperature and SWR protection and can be used to drive an amplifier of any power.

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 there 50W and 100W definitely get 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 PC remote control?
Its best that you look at the screen capture below. The program may change over time as we make enhancements, we will be adding more features soon! Feel free to ask for any features you may want.

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.

What is the Ethernet control module?
This optional add-on module lets you connect this FM transmitter to Ethernet. It lets you control frequency, power and RDS parameters from your PC remotely.

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. The Ethernet remote control part is not used here as the BE series has its own Ethernet interface in the front panel already.

What is MicroMPX IP stream receiver
MicroMPX is IP STL (studio-to-transmitter audio link) codec, specifically designed for FM radio. It doesn’t cause typical lossy codec artifacts (pre/post ringing, watery sound), and perfectly maintains peak control, even when using composite clipping. This eliminates the need to have an expensive high end audio processor at the transmitter site.
It transports complete MPX signal with RDS to your transmitter via internet. Stereo Tool software is needed in your studio to transmit the stream to your FM transmitters.

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 analyzer 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
