DBX - 1231 - Egaliseur Graphique

La gamme des égaliseurs graphiques série 12 DBX est conçue pour les environnements de sonorisation les plus exigeants.

La gamme se compose de deux modèles à deux canaux :

le 1215 (2 x 15 bandes 2/3 d’octave, format 2U) et le 1231 (2 x 31 bandes 1/3 d’octave, format 3U). Les DBX 1215 et 1231 offrent tous deux des caractéristiques communes telles que des fréquences centrales au standard ISO, une plage de gain d’entrée de ±12 dB, des filtres coupe-bas Bessel commutables à 18 dB/octave à 40 Hz et des faders à course de 45 mm, ainsi qu’une commutation ±6dB ou ±15 dB de l'efficacité, une connectique offrant à la fois XLR, Jack 6,35 mm et bornier, des entrées/sorties symétriques, un découplage de masse électrique/châssis et un transformateur d’alimentation interne.

Logés dans un boîtier robuste en acier et aluminium, les égaliseurs DBX série 12 sont conçus avec précision pour des années d’utilisation et une fiabilité à toute épreuve. Pour une compatibilité avec tous les types d’installations, la série 12 est équipée de transformateurs blindés, d’entrées et de sorties à symétrie électronique, avec filtres HF et d’un bypass par relais lors de la coupure du secteur. La mise sous tension dispose d’une temporisation de 2secondes. DBX a sélectionné les meilleurs composants pour les égaliseurs série 12, ce qui se traduit par une bande passante linéaire de 10 Hz à 50 kHz, un rapport signal/bruit supérieur à 90 dB (réf. +4 dBu), une distorsion à 0,0005 % (1 kHz à +4 dBu) et une diaphonie inférieure à –80 dB de 20 Hz à 20 kHz.

Specifications :

• Sélection de la plage d’efficacité (entre ±6 dB et ±15 dB)
• Entrées et sorties symétriques
• Connexions par XLR, bornier et jacks 6,35 mm
• Plage de gain d’entrée de -12 dB/+12 dB
• Filtre coupe-bas 18 dB/octave à 40 Hz de type Bessel
• Possibilité de découplage de la terre et du châssis
• Transformateur d’alimentation intégré
• 1231DBX : 2 U, 19 pouces

DBX - 1231 - Dual Band Graphic EQ

The DBX 1231  Dual Band Graphic EQ. High quality, respected and designed for the most demanding applications.

The DBX 1231 was designed to meet the needs of the most demanding sound reinforcement environments, while offering the simplicity of straightforward controls. The 1231 provides standard features like dual-channels, 31 1/3 octave bands, ISO frequency centers, +/- 12 dB input gain range, and switchable 40Hz/18 dB per octave low-cut filters, but also includes other insightful features. These include 45 mm faders; selectable +/-6dB or +/-15dB boost/cut range for precise gain adjustments; XLR, barrier strip, and 1/4 inch TRS connectors for installation ease; balanced inputs and outputs for quiet operation; and chassis/signal ground lift capabilities for quick hum isolation. The visionary design of the dbx 12 Series makes your job easier.

The main features of the DBX 1231 include :

• Switchable boost/cut ranges of 6 or 15 dB
• Electronically balanced/unbalanced inputs
• Servo balanced/unbalanced outputs
• RF filtered inputs and outputs
• XLR, Barrier Strip, and 1/4 inch TRS connectors
• -12dB/+12dB input gain range
• 18dB/octave 40Hz Bessel low-cut filter
• Chassis/signal ground lift capability
• Internal power supply transformer
• Power-off hardwire relay bypass with 2-second power-up delay
