  • The APC 542 can work stand alone managed from the Control Wheel and OLED Display but it can also be remote controlled from the Internet. You can create new settings using a simple PC or Tablet. It is the only processor that controls and optimizes the FM transmission using an internal FM Modulation Monitor.
     
    The 542 includes a new idea that has revolutionized the market: adding a FM Modulation Analyzer to the digital signal of your Radio. It allows fine tuning of 24 parameters and even check how your radio stations work to be sure that your radio is the best of town
    • Five bands worked with 5 x AGC; 5 x Comp; 5 x Limit; 5 x Clipper
    • Quadruples the power of its radio and sports programs Journalistic eliminating interference
    • World only that offers FREE Internet remote setting of the Processor + transmitter + antenna
    • Best voices of speakers for the music automatic mode - VOICE
    • Total flexibility: The 542 is a Universal Processor changing its performance by installing a new software
    • The software is updated remotely without interrupting programming to air and can do the same operator.
    • Monitor only includes FM radio with Sound Quality Analyzer
    • In case of failure of communication studies automatically switches audio input
    • One that lets you enhance the sound in the air correcting the chain: Coax Transmitter + cable + antenna.
    • Send messages to cell over transmission failures or operating
    • It includes internally to RDS Coder to see texts in FM receivers
    • It includes two versions of remote control software: one for engineers and one for operators (Commander Lite)
    • It includes MPX power meter and setting for constant energy with European standard ITU BS 412
    • Options 542 / AoIP for input and streaming RM-542 Remote control from studies

    The 542 also generates a list of 24 measurements of the on-air FM signal that you can send to Solidyne to have an accurate diagnosis of any technical problems.

    But there is much more, it is the first time that an audio processor and a Modulation Monitor operates together and synchronized under the control of an internal computer. And this opens up a new world that was never within the engineers reach even with the best modulation monitors of the market. This is due to the fact that the 542 not only measures the transmission; It generates the test signals to measure it after aired with no annoying the audience. This was never feasible before now it is possible to measure the stereo audio quality of the transmitter assembly + coaxial cable + antenna while the radio is on the air; without suspending the transmission for "technical adjustments".

    You can simply click on the mouse and make the measurements and generate a report so your engineer (or Solidyne) can advise you on how to improve your radio. 

    Now you can know if the channel separation is correct and the sound is of good quality by measuring the THD Harmonic Distortion, Signal to Noise Ratio, Stereo Phase Vector, RMS Power Levels, etc. 

    You can verify how the 542 APC changes the settings according to the musical themes that go to the air (through the signal of RDS) or pass from the musical adjustments to the setting "Announcers" when the console connects the microphones to the air all automatically.

    You will also receive an email on your phone or PC when any of the technical parameters or the human operation cause problems.

    You can control EVERYTHING with your radio operating 24 hours a day without having to leave the air to take measurements.
