Radial Engineering ProD2 2-channel Passive Direct Box

World-class Stereo Passive DI BOX

The ProD2 is a 2-channel passive direct box that connects stereo keyboards or high-output instruments to a PA system or home recording setup without noise or distortion.

At the heart of the design are two high-performance Eclipse ET-DB2 transformers. These deliver 20Hz to 20kHz performance with less than 1.5dB deviation above 18kHz and are able to withstand tremendous signal levels without distortion. Unlike active circuits that overload when the signal exceeds the rail voltage, transformers saturate. This creates a pleasing effect that naturally rounds out the tone, acting like a subtle limiter which is particularly advantageous when interfacing the ProD2 with digital pianos, samplers and drum machines that can produce excessive dynamics. Transformers are particularly adept at eliminating hum and buzz caused by ground loops.

Main features:

• Full-range passive direct box
• Isolation transformer eliminates noise
• Very low harmonic and phase distortion
• Compact and rugged design
• Ideal for live sound and studio
• Isolated XLR connectors eliminate chassis ground potential
• Custom audio transformer on input provides 100% isolation to eliminate hum and noise-causing ground loops while maintaining signal integrity
• Military spec PC board with full surface ground plane to reduce susceptibility to RF noise
• High-grade switches - long life, high cycle for reliable performance
• 14-gauge steel welded I-beam construction makes it virtually impossible to torque the PC board
• -15dB pad reduces the level going in from loud sources that could overload the circuit and cause distortion
• Book-end design creates a protective zone around the switches & connectors, indestructible 14-gauge steel construction
• Full no-slip rubber bottom pad provides mechanical isolation, electrical insulation and prevents unit from sliding around
• Balanced male XLR output connector, AES standard with pin-1 ground and pin-2 hot
• Lift switch lifts the ground to pin-1 on both channels
• Heavy-duty baked enamel finish for excellent durability and great looks for years
