The Audimax 362HD has 7 analog processing stages and the digital stereo coder. It works with 3 audio bands and has 7 front panel controls for customize the sound (so that your radio sounds different from the others) Its very low price tag is appropriate for community FM radios and low power stations. Model 362 has simultaneous stereo balances outputs for audio streaming in Internet and coaxial MPX output for FM transmitter. The 362-IT model is an excellent processor for WEBcasting because analog inputs has internal equalization for optimal performance of streaming (you can listen audio streaming; select it at the left menu)

Operating in a FM radio, the AudiMax 362 increases the reach of the FM transmission, improving the coverage area between 30 and 50%, obtaining an impressive audio quality that will distinguish your radio station. You can learn more about how processing improves the FM reach, at our Power Point presentation: Audio Processors (Spanish) .

AudiMax is fully controlled by VCA, being very simple to adjust. In fact, with all the knobs to the center position, your radio will sound perfect on the air. You don’t need a technician to make the settings. Its main characteristic is the ease of use, because it does not require a specialized technician to start up and to adjust the unit; and neither it has the critical Input level control, since an automatic system adapts the input gain to the output level of any audio console and radio-operators (still the most distracted...)The stereo coder stage uses digital synthesis with 16X oversampling, a technology developed by Solidyne that guarantees ultra-low distortion and high channel separation, not requiring any readjustment during all its full life. MPX output is differential type, with floating ground for cancelling the residual humming.

  • An audio expander ensures the elimination of background noise at times when there is silence
  • An AGC system (Automatic Gain Control) guarantees to enter the delicate multiband system with the same level of audio always, avoiding variations in the level of transmission of its radio due to different speakers or interviewees and even to errors of operation.
  • A phase rotation system employs Kahnn-Bonello peak symmetrizer technology, eliminating the asymmetry of the human voice that reduces the range of the radio and gives a sense of weakness to the sound
  • Dynamic Equalizer is a 3-band dynamic audio equalizer that allows you to reinforce certain frequencies, usually the bass, to have a sound with a strong punch of low frequencies, ideal for car radios. Unlike conventional equalizers whose action is lost for high levels of modulation, this equalizer emphasizes its action the higher the modulation
  • The Band Energy system increases the density of peaks in the 3 bands achieving very high loudness signals. It is adjusted according to whether the radio wants an aggressive or soft and melodious sound.
  • Multiband Compressor; it is the base of the processing system constituted by independent audio processors that act in 3 bands.
    The attack times are automatic adjustment.
    A single control allows modifying the gain at the input of the compressors.
    Exclusive Intermodulation cancellation filters allow the cleaning of
    sound that characterizes the 362HD
  • MPX clipper with instantaneous operation between 0 and 6 dB with SuperModulationtechnologythat allows to gain between 2 and 3 dB of audio signal without over-modulating the transmission
