This 30W transmitter is a still a worldwide favourite which has been on the market since 1999, it's reliable, it's durable and long lasting, even after 20 years there are various clients in the world still using this model for their community stations. This power level is suitable for a small town.
What is SUPER SILENT? it means it's as quiet as a mouse and can use it in a live mic studio without background noise. Check the video demonstration. If you want SUPER SILENT option, ADD TO CART here.
This is the most popular version because it includes everything in one enclosure. The audio processing keeps the audio level 'LOUD', but not too loud whereby it causes over deviation and contravenes your permit. The trick is to get the sound as loud as possible so you can compete with the other stations on the dial, but at the same time keeping your signal legal. This is a tricky balance to maintain, but this version in stereo with our internal audio processers does exactly this. More Information HERE.
As an optional extra this transmitter is available with dynamic and programable RDS fitted. If you want RDS option please (rds-upgrade) ADD TO CART

The output transistor can handle any amount of reflected power comfortably with a a rating of 45 watts on a more than sufficient large heatsink for cooling
The enclosure is made in strong 16 gauge steel, powder coated and baked in satin black. This leaves a tough, durable surface that will never rot or corrode and be cleaned to shine for decades. The front panel is 19 inch across and 2U (3.5 inch) high with a depth of 12 inches, so it will fit with ease into a standard rack. It is very strong and difficult to damage even under extreme handling.
If you are qualified or understand broadcast radio specifications and parameters you can set the frequency and deviation yourself. This is easily done by flipping over the unit and adjusting the little dip switches on the underside panel. More information on this in the User Manual, you can find a link to this below.
The stereo version with audio processing and limiting meets all the regulatory standards required out of the box and pre configured. In fact if you send us a copy of your permit and it's conditions, we will set it up exactly to the specification. This equipment complies with EU/CE harmonised standards and FCC technical requirements for FM broadcasting. More information HERE
