Radial JDI Stereo 2-Channel Passive Direct Box
Radial JDI Stereo 2-Channel Passive Direct Box
The World’s Finest Stereo Direct Box
The Radial JDI Stereo brings unprecedented sonic transparency and accuracy to any stereo instrument – providing the artist with the freedom to focus on their music.
Pure sound of the instrument
The Radial JDI Stereo is a passive two-channel direct box designed to handle extreme signal levels without distortion of any kind. It employs two world-class Jensen JT-DB-EPC audio transformers to deliver a smooth, warm sounding Bessel curve, reminiscent of the finest vintage gear. Ruler flat from 10Hz to 40kHz and with virtually zero phase deviation, the JDI Stereo delivers the natural, pure sound of the instrument without artifact. By its no-power passive design, the JDI Stereo performs both high-to-low impedance conversion and signal balancing over a magnetic bridge that passes signal while rejecting stray DC voltage. This makes it particularly adept at eliminating hum and buzz caused by ground loops.
JDI Stereo Applications
-
Two basses connected to amps and PA
The JDI Stereo is perfect for sending the pure bass signal to the PA system. Use the Thru connectors to feed two channels on your amp. -
Stereo laptop with controller keyboard
The Jensen equipped JDI Stereo is able to gracefully handle extreme transients from your digital piano, laptop or DJ mixer without choking. -
Two acoustic guitars connected to the PA
The smooth sounding Jensen transformers smooth out the peaks from your acoustic guitar to produce a nice rich, warm tone.
Features:
- Jensen transformer equipped passive DI
- Eliminates hum and buzz from ground loops
- Virtually zero phase & harmonic distortion
- Exceptional signal handling and noise rejection
- Compact stereo format for twice the performance
-
Thru
Thru-put from the JDI Stereo to the amp. Hi impedance will not load instrument down. -
Inputs Left & Right
Unbalanced 1/4″ input jacks used to connect instruments to the JDI Stereo. -
-5dB Pad
Reduces the input sensitivity for active basses and high output keyboards. -
XLR Out
Balanced 150? mic-level output wired to the AES standard with pin-1 ground, pin-2 (+) and pin-3 (-). -
Ground
Disconnects pin-1 at XLR output to reduce hum and buzz caused by ground loops. -
No Slip Pad
Provides electrical & mechanical isolation and keeps the JDI Stereo from sliding around. -
Powder Coat
Durable finish keeps your JDI Stereo looking great for years. -
Mil-Spec PCB
Full ground plane for noise-free performance, double sided for durability. -
Jensen Tranformers
Nickel core for the best signal transfer and MuMetal® shield for protection against EMI. -
Metal Switches
Rated at over 20,000 cycles for added durability and years of use. -
