Radial JDI Stereo: Unleash Pure Sound in Your Music Setup
Experience unparalleled sonic clarity with the world's finest stereo direct box.
• Pure Instrument Sound: Delivers the natural, pure sound of any stereo instrument without distortion. Its passive two-channel design with Jensen JT-DB-EPC audio transformers offers a smooth, warm Bessel curve, like vintage gear. Zero phase deviation from 10Hz to 40kHz ensures no artifacts.
• Eliminates Ground Loops: Thanks to its no-power passive design, it performs high-to-low impedance conversion and signal balancing over a magnetic bridge, rejecting stray DC voltage and eliminating hum and buzz.
• Versatile Applications: Ideal for musicians. Connect two basses, acoustic guitars, or a stereo laptop with a controller keyboard to the PA system or amps. The Thru connectors let you feed two channels on your amp. The -5dB pad adjusts for active basses and high output keyboards.
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
