  • BROADBANDED FM EXCITER

    LCD CONTROLLED FM EXCITTER15/25/50/100Watt / 87.5 – 108 MHz

    • Suitable for digital audio. FM exciters of last generation are fully compatible with digital audio. In fact the amplitude and group delay linearity extended to the sub-sonic frequencies avoiding the low-frequencies overmodulation and phase distortion exalts the musical quality of digital audio. Even the musical quality of traditional analogic audio is emphasized.

    • 0 ÷ 15/25/50/100 W maximum output power continuously adjustable by external control. Ideal as a stand-alone transmitter or a versatile exciter for power amplifiers.

    • Frequency agile. Instant direct frequency programability from LCD Sub Menu with 10KHz steps. No tuning or adjustments required.

    • Digital stereo coder. High performances digital STEREO CODER BUILT-IN (optional) with stereo separation (≥ 65dB) and signal/noise ratio (≥ 80 dB) for a top sound quality.

    • Top quality sound. The generated signal is characterized by an excellent signal/noise ratio and by negligible residual AM and FM. All this guarantees the best quality of the broadcast signal.

    •High frequency stability in short and long terms is assured by uProcessor Controlled Digital Phase Locked Loop circuit with low drift quartz reference.

    • Deviation limiter. Internal dynamic function limits the maximum frequency deviation according with the international requirements (CCIR, FCC, etc…). This is to avoid adjacent channels invasion in case of accidental overmodulation without reducing the modulation quality.

    • uProcessor Controlled protections with LCD front Panel Display in case of load mismatching (VSWR) or transmitting frequency error (PLL UNLOCK). Every alarm event is displayed by front panel LEDs and/or LCD display and can be resetted by automatic and /or manual control.

    • LCD Menu Metering/Indicators: Working Frequency, Forward Power, Reflected Power, Frequency Deviation, Internal Power Supply Voltage and Current, Heat Sink Temperature, Input Audio L & R levels are displayed by front panel LCD Display.

    • Adjustments and settings. Output power (PWR adj.), frequency deviation (DEV adj.) are front panel available or via Sub Menu on LCD front Panel Control for instant adjustment and setting.

    • Output low pass filter. It assures a pure RF spectrum, according to the international requirements.

    • Meets or exceeds international standards for safety and electrical specifications.

    Hello Web Admin, I noticed that your On-Page SEO is is missing a few factors, for one you do not use all three H tags in your post, also I notice that you are not using bold or italics properly in your SEO optimization. On-Page SEO means more now than ever since the new Google update: Panda. No longer are backlinks and simply pinging or sending out a RSS feed the key to getting Google PageRank or Alexa Rankings, You now NEED On-Page SEO. So what is good On-Page SEO?First your keyword must appear in the title.Then it must appear in the URL.You have to optimize your keyword and make sure that it has a nice keyword density of 3-5% in your article with relevant LSI (Latent Semantic Indexing). Then you should spread all H1,H2,H3 tags in your article.Your Keyword should appear in your first paragraph and in the last sentence of the page. You should have relevant usage of Bold and italics of your keyword.There should be one internal link to a page on your blog and you should have one image with an alt tag that has your keyword....wait there's even more Now what if i told you there was a simple Wordpress plugin that does all the On-Page SEO, and automatically for you? That's right AUTOMATICALLY, just watch this 4minute video for more information at. Seo Plugin

    Forgot to say WATCH THE ACADEMY AWARD-WINNING MOVIE “INSIDE JOB”—-then watch it again…AND AGAIN…you will get mad enough to fight and do whatever it takes to stay in your home and stick it to the banks, for what they did to the American people…and what they will continue to do…until we ALL start FIGHTING BACK with the LAW…which IS ON OUR SIDE.  The problem is the situation is so unprecedented and unfamiliar with judges and even lawyers, that we literally have to SHOW them how various laws were violated…I know it sucks, but WE HAVE TO DO IT FOR OUR FUTURE AND OUR CHILDREN’S FUTURE.

    Kualitas Stereo di FM dan AM hampir sama  karena AM Stereo system pemodulasiannya menggunakan system Digital, karena tidak ada system lain.
