Un bon manuel d’utilisation

Les règles imposent au revendeur l'obligation de fournir à l'acheteur, avec des marchandises, le manuel d’utilisation Dynaudio Air Series. Le manque du manuel d’utilisation ou les informations incorrectes fournies au consommateur sont à la base d'une plainte pour non-conformité du dispositif avec le contrat. Conformément à la loi, l’inclusion du manuel d’utilisation sous une forme autre que le papier est autorisée, ce qui est souvent utilisé récemment, en incluant la forme graphique ou électronique du manuel Dynaudio Air Series ou les vidéos d'instruction pour les utilisateurs. La condition est son caractère lisible et compréhensible.

Qu'est ce que le manuel d’utilisation?

Le mot vient du latin "Instructio", à savoir organiser. Ainsi, le manuel d’utilisation Dynaudio Air Series décrit les étapes de la procédure. Le but du manuel d’utilisation est d’instruire, de faciliter le démarrage, l'utilisation de l'équipement ou l'exécution des actions spécifiques. Le manuel d’utilisation est une collection d'informations sur l'objet/service, une indice.

Malheureusement, peu d'utilisateurs prennent le temps de lire le manuel d’utilisation, et un bon manuel permet non seulement d’apprendre à connaître un certain nombre de fonctionnalités supplémentaires du dispositif acheté, mais aussi éviter la majorité des défaillances.

Donc, ce qui devrait contenir le manuel parfait?

Tout d'abord, le manuel d’utilisation Dynaudio Air Series devrait contenir:
- informations sur les caractéristiques techniques du dispositif Dynaudio Air Series
- nom du fabricant et année de fabrication Dynaudio Air Series
- instructions d'utilisation, de réglage et d’entretien de l'équipement Dynaudio Air Series
- signes de sécurité et attestations confirmant la conformité avec les normes pertinentes

Pourquoi nous ne lisons pas les manuels d’utilisation?

Habituellement, cela est dû au manque de temps et de certitude quant à la fonctionnalité spécifique de l'équipement acheté. Malheureusement, la connexion et le démarrage Dynaudio Air Series ne suffisent pas. Le manuel d’utilisation contient un certain nombre de lignes directrices concernant les fonctionnalités spécifiques, la sécurité, les méthodes d'entretien (même les moyens qui doivent être utilisés), les défauts possibles Dynaudio Air Series et les moyens de résoudre des problèmes communs lors de l'utilisation. Enfin, le manuel contient les coordonnées du service Dynaudio en l'absence de l'efficacité des solutions proposées. Actuellement, les manuels d’utilisation sous la forme d'animations intéressantes et de vidéos pédagogiques qui sont meilleurs que la brochure, sont très populaires. Ce type de manuel permet à l'utilisateur de voir toute la vidéo d'instruction sans sauter les spécifications et les descriptions techniques compliquées Dynaudio Air Series, comme c’est le cas pour la version papier.

Pourquoi lire le manuel d’utilisation?

Tout d'abord, il contient la réponse sur la structure, les possibilités du dispositif Dynaudio Air Series, l'utilisation de divers accessoires et une gamme d'informations pour profiter pleinement de toutes les fonctionnalités et commodités.

Après un achat réussi de l’équipement/dispositif, prenez un moment pour vous familiariser avec toutes les parties du manuel d'utilisation Dynaudio Air Series. À l'heure actuelle, ils sont soigneusement préparés et traduits pour qu'ils soient non seulement compréhensibles pour les utilisateurs, mais pour qu’ils remplissent leur fonction de base de l'information et d’aide.

    30 ACOUSTICS - BACKGROUND INFO Acoustics When we talk about making a room "sound right", we are probably dealing with room acoustics as a science acoustics has been around for about hundred years.

    31 ACOUSTICS - BACKGROUND INFO Sabines formula Sabine is the father of modern acoustics. He found that reverberation time is described by a relationship between the room size and the amount of absorption in the room. Larger rooms - longer reverberation. More absorption - shorter reverberation. T = 0.161 * V / A where T : Reverberation time in secon[...]

    32 ACOUSTICS - BACKGROUND INFO Diffusers A diffuser provides dif fuse reflection of the sound radiated against it. It can be a very useful solution in cases where reflections are disturbing the sound image and it is not advisory to ad further absorption. So in order to reduce flutter echoes, comb filtering etc., special elements can be placed on th[...]

    33 BACKGROUND INFO - ACOUSTICS St anding W aves S tanding waves exist in all kind of rooms. The shape of the room, the dimensions of the room, and the relationship between the dimensions of the room, are important parameters that will determine the frequencies around which the phenomenon exists as well as the distribution of these standing waves. B[...]

  • Page 36

    34 ACOUSTICS - BACKGROUND INFO Room modes These special frequencies are also called room modes. S tanding waves between parallel walls are called axial modes. Other modes exist. For instance t angential and radial modes. (See the illustration). Normally the axial modes are the strongest. Axial T angential Radial[...]

  • Page 37

    35 ACOUSTICS - BACKGROUND INFO The standing waves are characterized by having a maximum sound pressure at the boundaries of the room. Depending on the frequency there are one or more dips across the room. In a box shaped room the frequencies can be calculated as follows: where f = frequency in Hz c = speed of sound (approx. 340 m/s or 1 130 ft/s) l[...]

    ACOUSTICS - BACKGROUND INFO 36 At low frequencies a monitor can be considered as to radiate the sound energy in all directions. This is also called a 4 π radiation. When placing the monitor close to a solid boundary - for instance a wall - the sound energy that should have been radiated in the direction of the wall instead is radiated into the fre[...]

    37 ACOUSTICS - BACKGROUND INFO Comb Filtering The filtering function that arises when a signal is added to itself af ter having been delayed in time is called a comb filter . The resulting frequency response resembles a comb, hence the name. T wo 500 Hz sinusoidal tones added. The second tone is delayed 1 ms hence the sum is zero T wo 1 kHz sinusoi[...]

    ACOUSTICS - BACKGROUND INFO 38 T wo typical situations in which comb filters arise, either acoustically or electrically . In general: All digital signal processing takes time. This means in practice that comb filter effects can arise if you loop a signal via, for example, a compressor and combine this signal with the original. An example of a comb [...]

    39 ACOUSTICS - BACKGROUND INFO Rear wall cancellation When the monitor is set up at some distance in front of a wall, reflections from the wall may occur and influence the perceived frequency response. This could result in comb filtering if all frequencies produced by the monitor were radiated in all directions. But the monitors are typically only [...]

    THE SUBWOOFER - BACKGROUND INFO 40 The Subwoofer A subwoofer is a monitor that reproduces low frequencies. The purpose is to t ake over from the main monitor(s) as frequencies approach the lower end of the frequency range. I.e. approximately below 120 Hz. When used in professional monitor systems it is commonly preferred to use subwoofers below app[...]
