3-Band FM Audio Processor



With its advanced functionalities and impressive versatility, SOUND4 PULSE Eco gives broadcasters the ultimate price - performance ratio, providing much more value than just a basic FM processor. Flexible and powerful, it ensures perfect sound quality and full compatibility with radio broadcasting standards and can be used simultaneously for FM and HD, DAB, DRM or streaming.

One of the most distinctive features of the SOUND4 PULSE Eco is the three-band processor which is at the heart of dynamic processing. A single algorithm guarantees the gain in each of the bands in order to complete sound stabilization. “Coloring” is controlled by the Fidelity parameter. Thus, it is possible to have a "purist" and a "colored" sound texture. The 3-band Process is achieved through the revolutionary algorithm S.I.S. (Sound Impact System), which makes it possible to maintain the authenticity of the original sound attacks.

Another great feature of this model is the intelligent 2-band Automatic Gain Control whose main purpose is to stabilize the input levels and prevent noticeable level differences between recent and old titles. This product also has a real stereo enhancer and a 3-band stereo image limiter acting on the control of the energy transmitted by the stereo sub-porter at 38 kHz. This unique functionality limits issues currently caused by the traditional enhancement processes. The stability of reception in areas "disturbed" by Multipath conditions is thus greatly optimized.

SOUND4 PULSE Eco has Analog, Digital and AES-67/Livewire inputs and outputs, as well as an MPX FM output. The outputs of SOUND4 PULSE are fully assignable. For example, the analog output may replicate the signal which is fed to the analog input, the digital output delivers an HD signal, the TX1 one delivers the MPX signal and the TX2 output drives the 19-kHz pilot signal. Your investment is very well protected with ability to upgrade by the licensing to the next step in the processing features - top of the line Impact Eco 6-band processor.

Thanks to the capacity of its memory card to store audio files, SOUND4 PULSE Eco also guarantees bulletproof backup functionalities, ensuring continuity of the on-air programming and solving the problem of radio silence. Additionally, SOUND4 PULSE Eco provides an optional streaming output fully compatible with all standard servers, including HLS.
