With its advanced functionalities and impressive versatility, SOUND4 PULSE gives clients the ultimate price - performance ratio, providing much more than just a 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 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 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.
Due to the capacity of its memory card to store audio files, SOUND4 PULSE also guarantees bulletproof backup functionalities, ensuring continuity of the on-air program and solving the problem of radio silence.

The SOUND4 PULSE has four inputs - Digital, Analog, IP (Livewire or SOUND4 IP Connect) and PCI.
On the software interface, the input currently in use is indicated by a triangle on the left side of its name.
With the SOUND4 PULSE, the first processing function is the 2-Band AGC - automatic gain control whose main purpose is to stabilize the loudness level applied to the input of the processor and prevent noticeable level differences between recent and old titles.
The Tone FX makes coloring of sound before dynamic processing possible. To do so, it groups together two types of processing functions:
- A 4-band parametric equalizer;
- An effect system making it possible to strengthen low frequencies and high frequencies.
The two functions offer results that are entirely different, which is why they are gathered on one single screen.
In Basic mode, use of the four parametric equalizers is simplified to the maximum. Only the gain for each correction is accessible. For FX Bass and FX Treble, dosage of the effect is also made accessible.
In Advanced mode, users have access to all equalizer parameters (gain, frequency and Q factor).
SOUND4 PULSE has a true stereo enlarger, 100% mono-compatible. Its role is to sublimate the existing stereo image. It will thus never create stereo in mono sources.
In addition to embellishing the stereo image, it also has 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 enlargement processes. The stability of reception in areas disturbed by multiple routes is thus greatly optimized.
The 3-Band Process
The 3-band Process is the heart of dynamic processing. With SOUND4 PULSE, 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.
The 3-Band Limiter
The main purpose of the 3-band Limiter is to prepare the work of the final limiter. It is also provided with a very powerful predictive algorithm, which has been simplified to the maximum, so that it is not encumbered with useless parameters.
The Final Limiter
The Final Limiter comprises two sections - one for FM applications and one for HD applications.
The FM Section consists of a Bass Clipper, guaranteeing powerful bass without distortion, an FM limiter and an MPX limiter.
The HD Section is specifically designed for high quality digital applications (HD/DAB/DRM). This is a look-ahead type of limiter and in this mode the outputs are not limited to 15 kHz.
Assignment of Outlets
The outlets of SOUND4 PULSE are fully assignable. For example, the analog outlet may replicate the signal which is applied to the analog input, the digital outlet delivers an HD signal, the TX1 outlet delivers the MPX signal and the TX2 outlet drives the 19-kHz pilot signal.
