  • SOUND4 FIRST offers a full set of the most important features required from an FM/HD processor in a small, compact PCI Express card. Powerful, yet affordable, it produces clear audio of unrivalled quality. It is 100% autonomous in terms of resources and only requires power from your PC. This PCIe card gives you intelligent and highly efficient 2-band processing, a digital stereo generator and an IMPACT Clipper in one single product.

    Among its most important advantages are an HD Limiter, a Low Distortion Bass Clipper and a Low Distortion FM Limiter. SOUND4 FIRST comes equipped with Analog, Digital and AES-67/Livewire inputs and outputs, as well as an MPX FM output and a streaming output fully compatible with all standard servers, including HLS. Additionally, it solves the so-called “blending problem” resulting from the switch of receivers from stereo to mono, bringing you a constant level of clear audio. The product is fully BS-412 compliant and has a reliable backup source which ensures an uninterrupted audio stream.

    What is especially worth mentioning are the software options that customers can choose from, depending on their specific requirements. These options include Basic and Full RDS, PCI Radio Driver In/Out, Streaming Extension, IP TX + RX and Dual IP TX + RX.

    All of this makes SOUND4 FIRST your essential PCIe card and a guarantee of superb performance.

    SOUND4 FIRST Fields of Application
    The SOUND4 FIRST is a three-band processor and the smallest device in the FM product line. It is particularly well-suited to the following uses:

    For small radios, as a principal processor. It is fully compliant with radio broadcast standards while at the same time having a strong, clear and balanced sound.
    For transmitter finalization, with a SOUND4 FIRST located in the studio. All radio standards are met.
    For radios seeking natural but powerful tonalities.
    As a web radio processor, thanks to its algorithms, specially optimized for this kind of application. Furthermore, its low cost makes it affordable for any radio station wishing to set itself apart from other stations.
    As a small standby processor.
    The SOUND4 FIRST can thus be used as an audio broadcaster thanks to the PCIe entry driver, as a processor thanks to the processing functions and as an Audio streamer thanks to the streaming option.
    A Highly Versatile Processor
    The SOUND4 FIRST is the first small processor that has been specifically developed for new radio markets. The outputs can thus be used simultaneously for FM and HD, DAB, DRM or, of course, WebRadio.

     An Integrated Backup Solution
    Much more than a mere processor, the SOUND4 FIRST has Audio Backup functionalities. Due to the capacity of its hard disk to store audio files, it is the first processor that guarantees continuity of the on-air program, solving the problem of radio silence.
    An Integrated Basic RDS Encoder
    In addition to being a high-quality processor and offering a backup audio source, the SOUND4 FIRST also provides the option of a basic or a full RDS encoder, the latter being UECP-compatible.
    Fully Compliant with All Standards
    With the SOUND4 FIRST, clients can be sure that they have a product which meets the various radio broadcast standards worldwide. It thus fulfills the following criteria:

    Excursion in frequency - once the output level is fixed at 75kHz, it will never go beyond this maximum limit.
    Multiplex Power - valid mainly in Europe, the ITU-R 412 recommendation is applied perfectly in accordance with the requirements of the radio broadcasting authorities.

  • Input State
    The SOUND4 FIRST 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.
    2-Band AGC
    With the SOUND4 FISRT, 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.
    Tone FX
    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).
    Stereo FX
    SOUND4 FISRT 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 FISRT, 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 FISRT 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.
