Description française :


La JDI Duplex de Radial est une double DI passive conçue pour apporter le maximum de flexibilité à l'ingénieur du son dans les applications les plus exigeantes.

Elle est équipée de 2 transformateurs pour un transfert du signal optimal avec un minimum de distorsion tout en produisant le son chaud qui a rendu Jensen légendaire. La JDI est parfaite pour donner un caractère analogique aux sources digitales telles que les samplers ou les claviers numériques qui ont tendance à sonner "froid".

Chaque canal a 2 entrées Jack 6.35mm et RCA (parallèles) pour la connexion des sources et la sortie thru vers un appareil à haute impédance. A ceci s'ajoute une entrée XLR pour la connexion d'une source à +4dB. En façade, on trouve un switch PAD qui réduira le signal d'entrée de 15dB, un filtre coupe haut pour éliminer les bruits parasites des vieux équipements électroniques, ainsi qu'un switch Merge qui permet de sommer les 2 entrées vers 1 sortie mono.

  • Idéale pour guitares acoustiques et basses
  • Claviers, batteries électroniques et modules de sons
  • Tout instrument électronique à haut niveau de sortie
  • Elimine hums et buzzs dans les systèmes sons

English description :


The Radial JDI Duplex is a full-feature, stereo passive direct box designed to enhance connectivity, reduce noise, and simplify the hectic life of the touring professional, broadcast engineer or AV integrator. It is plug-and-play easy to use while delivering the utmost sonic quality.

Like the Radial JDI, the Duplex employs two high-performance Jensen audio transformers with the same pristine audio signal path that has made the JDI the industry standard. It features exceptional signal handling with virtually zero phase shift or harmonic distortion, while remaining linear across the entire audio spectrum. When driven to extremes, the natural transformer saturation and resulting warm Bessel curve makes the Radial Duplex the perfect choice for smoothing out highly dynamic instruments such as digital pianos and electronic drums that can sound harsh when pushed. Transformer isolation provides the additional benefit of eliminating troublesome ground loops that can cause hum and buzz in the audio system or interfere with video displays.

This 'Swiss Army knife' DI is equipped with ¼' connectors for instruments, RCA connectors and a 3.5mm TRS for unbalanced -10dB consumer electronics plus XLR inputs for +4dB professional line sources. Radial's innovative book-end design provides protective zones on the front and rear to keep connectors and switches out of harm's way. The 14 gauge I-beam inner frame adds tremendous rigidity to eliminate outside stresses that could torque the PC board and cause premature solder joint and trace failure. The steel outer shell couples with the transformer's MuMETAL® shield to protect against stray magnetic fields from power transformers or lighting systems that could cause interference. Finally, a full-bottom no-slip pad works double-duty by providing both mechanical and electrical isolation. The Radial Duplex delivers outstanding connectivity, superlative audio and quiet dependable performance..

JDI Duplex… the world's finest passive stereo direct box.

Features :

  • Stereo direct box for high output sources
  • Ultra linear response from 10Hz to 40kHz
  • Virtually zero phase & harmonic distortion
  • Eliminates hum and buzz from ground loops

Duplex with Stereo Keyboard

The Duplex is able to withstand huge transients without distortion. This gives digital keyboards a warm, smooth vintage tone.

Duplex with Two Stereo Sources

With the dual stereo architecture, the Duplex can easily be set up to handle two different stereo sources at the same time.

Duplex in Multimedia System

Whether you have a CD player, iPod, computer or professional +4dB balanced source, the Duplex can handle any situation.

Please note that we sell European 220/240v versions, most of which can be switched to 110/120v if needed, either directly via the hardware next to the power supply, or via an external power transformer, don't hesitate to contact us if you have any questions.
