30 WATT FM TRANSMITTER SYSTEM
PROFESSIONAL RANGE
Continuous reliable power.....
|
|
Our 30W PLL Stereo Transmitter system comprises of a 1W driver and a 30W power amplifier. This neat combination is suitable
for professional fm broadcasting in most countries of the world. The
transmission range of this transmitter used with an high gain antenna could be up to 12 miles.
Any frequency between 87.5 to 108 MHz can be accurately programmed on the internal dip switches and locked up to meet
the broadcast spec in less than 15 mins. By adjusting a small pre-set control inside the power amplifier unit the RF power
output level can be set anywhere from 1W to 30W. Internal jumpers inside the driver allow the audio pre-emphasis to be
easily selected to the correct time constant of 50uS, 75uS (USA) or none.
Expensive test equipment is NOT required. Setting up is a simple task using the LED's on the front panel. This transmitter
system operates on any AC supply from 90V to 260V or 13.8V DC, this makes battery backup very easy and suitable for use
anywhere in the world.
This FM transmitter along with all our other products comes with a full twelve month guarantee and our reputation of high
reliability. On delivery the equipment is ready to plug in and use with any suitable 50 ohm antenna system such as our
Vertical 5/8 Wave, Single Dipole
or Stacked Dipole.
The measurements below were carried out using the supplied mains power supplies over the following extreme operating conditions.
- ambient temperature: 0°C to 40°C;
- mains voltage: Uo + 6% to -10%;
