OUR POPULAR 15W FM TRANSMITTERS WITH DSP AND RDS 

New enhanced version is out! CYBER MAX FM+ 15W is the first from a line of rack mounted FM transmitter series for demanding broadcasters, operating in the whole band II, from 87.5 to 108 MHz (extended Japanese band can be ordered as well). Transmitter consists of a stereo encoder with pre-emphasis circuit, active low-pass filter, our professional series PLL synthesizer/exciter, 15W wideband no-tune RF output stage with SWR and temp protection and an optional mains power supply. Unit is housed in a professional 19" rack mount enclosure. It is rugged and made for 24/7/365 operation. Each unit has a wide-angle high contrast backlit LCD display. The best value for your money.
This unit can give up to 20Wmax clean RF power, but this is not recommended for long term operation (10-15W tyical) .
RDS parameters can be programmed with the help of a PC via serial RS232 connection (cable and software included).

Note: This popular unit is now available in 5 versions.
- Regular version has a regular stereo encoder, no DSP functions and no RDS
- DSP version has a profesional DSP stereo encoder, XLR inputs and no RDS
- DSP/RDS version has both, profesional DSP stereo encoder with XLR inputs and RDS encoder
- RDS/XLR version with a basic RDS encoder and XLR inputs, but without the benefits of DSP processing
- MONO version without stereo encoder for those with no need for stereo

What are the benefits of DSP stereo encoder?
Very shart input filters with a deep 19KHz notch, advanced signal processing with compressor and limiter, all adjustable via LCD display

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. Serial programming cable for COM port is included.

What are XLR inputs?
These are balanced audio inputs, usually used by professionals. Their advantage is immunity to noise and ground loops. Hum and other noise artefacts that sometimes torment operators due to ground loops usually magically dissapear once XLR inputs are used.
