- Do not open the unit or attempt service yourself. Deadly mains voltage is present inside. There are also high RF voltage points that can cause burns and discomfort if touched. - Finally, never ever operate any transmitter or amplifier without a properly tuned antenna!

Chapter Introducing CYBERMAX FM+ series of transmitters Our series of rack mounted stereo FM radio transmitters with optional RDS and DSP processing his manual covers our 15W CYBERMAX FM+ transmitters. Even though the design of these units evolved radically over the years transmitters from this series remain one of our best selling items. Today our customers still enjoy the incredible price/performance ratio and more reliability, power and features than ever before.
And if you encounter a problem please let us know so that we may improve our products, offer advice and suggestion. From all of us we wish you happy broadcasting! Your PCS Electronics team Brought to you by PCS Electronics, www.pcs-electronics.com...

Separate extensive manuals for all of the built-in components are available on our website. We have a section in our forum dedicated to all of the manuals and you can discuss each of the manuals with other forum members here: http://www.pcs-electronics.com/phpBB2/viewforum.php?f=33...
It is recommended that you read this section before you power your unit up for the first time. Let us clear up some basics you should know about. You will also find some useful tips in our guides and forum at http://www.pcs-electronics.com.
You need some kind of audio source to drive your transmitter. This will typically be either a computer (just plug the cable into your sound card outputs, a mixer and a variety of audio sources, such as a microphone, CD player, DAT player, tape deck, gramophone, MP3 player etc. Brought to you by PCS Electronics, www.pcs-electronics.com...
- You can now connect audio sources of choice and verify audio performance. You should not sound louder than other stations, in fact unless you have an expensive high performance software or hardware sound processor you should sound quieter than other stations. Brought to you by PCS Electronics, www.pcs-electronics.com...
If you go downhill your speed will be greater with same amount of gas pedal. Likewise here your supply voltage can affect the actual output power slightly. <STEREO MODE> You can set your transmitter to MONO or STEREO here. Brought to you by PCS Electronics, www.pcs-electronics.com...
Digital signal processor starts compressing the signal beyond that point. The higher the ∞ compression ratio the higher the compression. For example, compression ratio of 1: would in effect be a limiter. Fig. 8: Explanation of the compressor settings Brought to you by PCS Electronics, www.pcs-electronics.com...
Left and right channel volume (only with DSP stereo encoders) This option allows you to precisely adjust the input sensitivity of both audio channels. This is very useful when your audio source has either too high or too low output level. Brought to you by PCS Electronics, www.pcs-electronics.com...
55 degrees C at maximum output power. This alarm applies to externally sensed temperature (ControlMini2), if you are using external PWR/SWR METER. <SWR ALARM> You can set the sensitivity of software driven SWR alarm here. <BAND SELECT> CyberMaxFM+ supports three bands: Brought to you by PCS Electronics, www.pcs-electronics.com...
Next check the troubleshooting table on the next page. If you have problems you cannot solve yourself, please see our website for contact information and support resources in our forum.

Output power less than expected Units can have slightly reduced output power at the band edges around 88 and 108 MHz. You can improve performance by tweaking coils in filter a little bit. Brought to you by PCS Electronics, www.pcs-electronics.com...
90MHz 792mm 819mm For other antenna designs check our web site here: http://www.pcs-electronics.com/guide_antenna.php Some more improvement tips Think about purchasing SWR meter to tune and align your antenna. A good antenna system is extremely important and can make up for a lot of power. For a suitable SWR meter check: http://www.pcs-electronics.com/cn101l-daiwa-power-meter-p-347.html...
MPX signal is passed to its MPX input (all mono transmitters have this input). Such exciters can than optionally drive big amplifiers with powers going into tens of KW with maximum range. You can check our amplifiers here: http://www.pcs-electronics.com/fm-amplifiers-c-41.html You can check our wireless STL links here: http://www.pcs-electronics.com/wireless-audio-links-c-42.html Brought to you by PCS Electronics, www.pcs-electronics.com...
C to 9dBd you’d need 8 dipoles. And for 12dBd you’d need 16 dipoles. 16 dipoles would in theory increase your range 4x compared to a single dipole. In practice there would be some losses in combining so many dipoles. You can use circular dipoles in very similar configurations. Brought to you by PCS Electronics, www.pcs-electronics.com...
It is also possible to have cables of different lengths, but you have to know velocity factor of the cable so we have omitted this for simplicity reasons. If you want more info please contact our technical staff. Brought to you by PCS Electronics, www.pcs-electronics.com...
Next you can connect external stereo encoder or wireless link receiver to the MPXin input at the back of the unit. If you get stuck or need our advice please contact our technical department. Brought to you by PCS Electronics, www.pcs-electronics.com...
Fig. 25: RDSMAX 4000+ windows application splash screen Once the installation is done you are ready to start the program. You are now ready to establish connection with the RDS encoder and configure all the RDS parameters. Brought to you by PCS Electronics, www.pcs-electronics.com...
In Windows go to Start > Settings > Control Panel > System > Hardware tab > Device Manager (This can vary depending on your Windows version). You should have something like this on your screen at this point: Fig. 28: Configuring Com port for USB driver Brought to you by PCS Electronics, www.pcs-electronics.com...
Take note of the COM port number here, you will need it later to configure the COM port inside RDSMAX4000+ windows control program. If you wish to change this port right click on the PCS USB-COM port and select Properties.
