Radial ProD2

Stereo Passive Direct Box

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

• Stereo direct box designed for keyboards

• Smooth, warm sound rounds out digital edge

• Able to handle huge transients without choking

• May be rack mounted for touring rigs

World class DI
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.

FEATURES

1/4" Input
Instrument connection to the ProD2

Thru
Instrument thru-put to an amp. High impedance thru will not load-down instrument's tone.

-15dB Pad
Reduces the input sensitivity for active basses and high-output keyboards.

XLR Out
Balanced 600 Ohm mic-level output, feeds mixers or mic preamps.

Ground
Lifts pin-1 at XLR to reduce hum and buzz caused by ground loops.

Book End Design
Creates a protective zone around the jacks and switches.
