ProDI / ProD2 Features & Specifications
 
                       

The ProDI and ProD2 share the same feature set.
Look inside a ProDI or ProD2 and you will find the build quality and components to be of only the highest professional standards. Radial's proven construction methods and materials ensure years of trouble-free service. The ProDI and ProD2 feature audio transformers custom made to our exacting standards to achieve the highest possible audio quality while maintaining an affordable price. The ProDI and ProD2 easily outperform all other direct boxes in their price range in both signal integrity and features
    Inside the ProDI and ProD2
  1. Isolated XLR connectors to eliminate chassis ground potential.
  2. Custom audio transformer on input provides 100% isolation to eliminate hum and noise causing ground loops while maintaining signal integrity.
  3. Military spec PC board with full surface ground plane to reduce susceptibility to RF noise.
  4. High grade switches - long life, high cycle for reliable performance.
  5. 14-gauge steel welded I-beam construction makes it virtually impossible to torque the PC board.



         
    ProD2 Input and Output Panels
  6. PAD - 15dB pad for LEFT channel reduces the level going in from loud sources that could overload the circuit and cause distortion.
  7. LEFT INPUT and THRU - instrument 1/4" input and thru-put to amplifier.
  8. RIGHT INPUT and THRU - instrument 1/4" input and thru-put to amplifier.
  9. PAD - 15dB pad for RIGHT channel reduces the level going in from loud sources that could overload the circuit and cause distortion.
  10. Book-end design creates a protective zone around the switches & connectors, indestructible 14-gauge steel construction.
  11. Full no-slip rubber bottom pad provides mechanical isolation, electrical insulation and prevents unit from sliding around.
  12. LEFT - balanced male XLR output connector, AES standard with pin-1 ground and pin-2 hot.
  13. LIFT ground pin-1 - switch lifts the ground to pin-1 on both channels.
  14. RIGHT- balanced male XLR output connector, AES standard with pin-1 ground and pin-2 hot.
  15. Heavy-duty baked enamel finish for excellent durability and great looks for years!
     

Construction

The ProDI and ProD2 are designed to withstand the rigors of the most demanding high-use professional environments. Radial pioneered the use of it's innovative 'book cover' design, which provides a protective zone around the switches and connectors that keeps these components safe.

Stress on circuitboards causes broken and intermittent solder joints, a common cause of failure in commercial rental and other high-use environments. Radial's 14-gauge welded I-beam inner chassis and 14-gauge outer shell greatly reduce the possibility of torque stresses being applied to the PC board.

A full-bottom no-slip rubber pad works double-duty by providing protection from electrical shock and making sure these DI's stay put.
