Solidyne - Digital Power

FM audio processor model 362

The best chose for lovers of HI-END analog sound

The Audimax 362 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 por audio streaming in Internet and coaxil MPX output for FM transmitter. The 362-IT model is an excellent processor for WEBcasting because analog inputs has internal eculization 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.

The input level is self-adjusted for any audio console and supports variations of the VU-meters level originated by DJs or radio operators.

Processing 1: An audio expander guarantees the suppression of background noise when silence of between pauses on the locution.

Processing 2: An AGC (Automatic Gain Control) system guarantee that the input level to the sensitive multiband system always be at the same level.

Processing 3: A phase rotation system uses the Kahnn-Bonello technology for cancellation of asymmetry peaks. This eiminate the asymetry of the human voice that reduce the reach of the radio and gives a sensation of weak sound.

Processing 4: Dynamic Equalizer is a dynamic audio EQ of 3 bands that allow reinforcing certain frequencies, generally the bass, to have a sound with a loud punch, ideal for the car-stereos. Unlike the conventional EQ, whose action is lost for high levels of modulation, this equalizer emphasizes its action, as grater is the modulation.

Procesing 5: The Band Energy system increases the peak density for the 3 bands obtaining signals of very high loudness. One adjusts based on the kind of sound wishes by the radio: an aggressive or smoother sound.

Processing 6: Multiband Compressor is the core of the processing system, constituted by 3 independent audio compressors that works on 3 frequency bands: Low, Mid and High. The attack times are automatic and the user controls recovery times with the Band Energy controls. One control allows modifying the input gain of the compressors. The band of high, being affected by the 75 uS pre-emphasis, has at the compressor output an ultra-fast peak limiter, followed by a Intermodulation cancelling filter to obtain a total cleaning sound in the high frequencies.

Processing 7: The sum of the signals is sent to the stereo coder. It has a safe clipper that acts at 0 to 6 dB and works over the MPX using a technology called SUPERMODULATION, increasing the audio signal between 2 and 3 dB, without over modulation.

362 have separated audio outputs for MPX and for WEBcasting. Their excellent internal construction, with IC mounted on sockets and components identification, turns it an equipment of excellent professional quality, of very moderate price.
