Les préamplis micro de la gamme AuviTran Audio ToolBox: testés et approuvés par le CFPTS (Centre de Formation Professionnelle des Techniques du Spectacle)

Créé il y a plus de 40 ans, le CFPTS est aujourd'hui le plus grand centre de formation continue aux techniques du spectacle en Europe.
Avec plus de 160 250 heures stagiaires en 2011, le CFPTS est donc devenu une référence reconnue et incontournable dans son secteur.
Pour la partie audio, le CFPTS organise une quinzaine de stages annuels, avec les meileurs produits et techniques du moment.
   Aussi sommes nous ravis d'entendre dire du bien du CFPTS sur nos équipements.

Début Janvier  2012, AuviTran a réalisé en partenariat avec le CFPTS une session d’écoutes comparatives en aveugle.

Sur un plateau Live, face aux nouvelles cartes Préampli Micros AxC-AX4M AuviTran, le CFPTS avait choisi de tester des préamplis convertisseurs réseau haut de gamme :

• l’AD8HR Yamaha équipé de son kit EtherSound,
• l’AQONDA 16 de Digigram
• le MICSTASY RME équipé également de son kit EtherSound

Préamplis micros AuviTran pour la gamme Audio ToolBox, jugés d’excellente qualité
face à Yamaha AD8HR, Digigram Aqonda et RME Micstasy

Le jury - composé de formateurs du CFPTS et de professionnels de l’audio allant du classique à la variété-  a bénéficié d’un plateau de musiciens pour juger des qualités de chaque appareil. La scène, équipée d’une façade en Nexo et de retours en L-Acoustics a été entièrement câblée en réseau et en numérique aux NXAMP de Nexo comme aux LA-4 raccordés grâce à une Audio Toolbox équipée de sorties AES-EBU. Un enregistrement simultané a permis de réécouter les sessions pour comparer à nouveau les préamplis écoutés.

Si la matinée de tests a  été consacrée aux écoutes comparatives en aveugle, l’après-midi a permis de se pencher plus en détails sur le comportement de l’Audio Toolbox, avec des points précis comme l’écoute du seuil de bruit, le comportement en saturation ou les bruits de commutations des étages de gain de l’appareil.

Après cette journée complète  de tests, le jury a conclu que les préamplis micro de la gamme AuviTran Audio ToolBox sont au « top du top » de la qualité, et ce pour un prix et une modularité imbattables.

Lors des tests, les jurés ont particulièrement noté l’absence de bruit, la transparence et la précision analytique des Audio Tool Box testés.

Le jury... impitoyable et convaincu

Cette série de tests approfondis en situation de terrain nous permet de constamment affiner nos produits, afin de nous rapprocher au mieux des besoins de nos utilisateurs.

Aujourd'hui disponibles commercialement, les cartes AxC-AX4M avec quatre préamplis micro permettent de créer des configurations en réseaux, aussi bien sur scène qu'en régie.

Avec la gamme AuviTran Audio ToolBox:

Choisissez votre réseau audio et vos configurations audio, bridgez vos configurations réseaux

La gamme AuviTran Audio Toolbox propose désormais 12 cartes disponibles pour l’AVBx3, la version 1U du rack AuviTran Audio Toolbox. 

Les cartes DANTE™, COBRANET™ et ADAT™ viendront se rajouter à la gamme dès septembre 2012. En parallèle, la carte AxC-DANTE est déjà prête pour l’AVB. 

Ultra modulaire, la solution Audio Toolbox ouvre des possibilités très larges pour l’utilisateur qui devient lui-même le concepteur du produit dont il a besoin.

AuviTran se place ainsi en leader des breakout-box multi réseau, qui permettent non seulement de raccorder des entrées sorties de tout type vers EtherSound™, Dante™, Cobranet™ ou Madi, mais également de bridger n’importe lesquels de ces réseaux.

Un grand merci aux équipes du CFPTS pour leur temps et leur aide !

La Gaite Lyrique, Paris - More than 360 x roof loudspeakers, all EtherSound connected and individually adressable

Situated in the heart of Paris, La Gaite Lyrique began in 1862 as a theater.
Inaugurated in March 2011 in its new format, La Gaite Lyrique is now a creation and resources center dedicated to digital medias and arts, and to modern music creations.
Completly reformed and reinvented, la Gaite Lyrique now offers various creation rooms, concert halls and resources centers.

La Gaite Lyrique 2.0 - Architecture: Manuelle Gautrand

In close collaboration with the audiovisual designer (Labeyrie), the choice has been made to have a completely digitally networked creation tool in all spaces of the building (including halls), and thus providing artists with an unique creation tool: all loudspeakers in all levels of the building are connected and indiviudually adressable, through EtherSound
AuviTran AVP4-ES100 digital EtherSound roof amplifiers (4x10W) have been widely  used to provide these unique features.

Audiovisual design: Labeyrie & associés (www.labeyrie.net)
Integrator: IEC Paris
Products involved for the sonorization of all halls of the creation center:
93 x AuviTran AVP4-ES100 EtherSound connnected amplifiers (4x10W), connected to
360 x roof loudspeakers
In complement, Amadeus active loudspeakers and subwoofers directly connected to the EtherSound (20 x Sub ML12-ES and 4 x PM5-ES)
2 x AV3rd-ES100 for multidiffusion to EtherSound from PC (with Abbleton Live software)
1 x Innovason Eclipse console for routing matrix

Other Innovason consoles and Amadeus loudspeakers are used in the main concert hall
