With its advanced features and impressive versatility, the SOUND4 PULSE ECO offers broadcasters the best price/performance ratio, providing much more value than a simple basic FM processor. Flexible and powerful, it ensures perfect sound quality and full compatibility with broadcast 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 the heart of dynamic processing. A unique algorithm guarantees gain in each band to complete sound stabilization. “Colouring” is controlled by the Fidelity parameter. Thus, it is possible to have a “purist” and “colored” sound texture. The 3-band process is achieved through the revolutionary S.I.S. (Sound Impact System) algorithm, which maintains 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 input levels and avoid noticeable differences between recent and old titles. This product also has a true stereo booster and a 3-band image limiter that controls the energy transmitted by the stereo subcarrier at 38 kHz. This unique functionality limits the problems currently caused by traditional enhancement processes. This greatly optimizes reception stability in areas “disturbed” by multipath conditions.

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

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