Radial ProD2: Stereo Sources Made Simple

Keyboards, laptops, and DJ mixers produce stereo signals that need two DI channels. The ProD2 puts both in one rugged box, with custom transformers that handle strong signals without saturation and keep bass and midrange phase distortion extremely low for a full, clear sound.

Eliminate Hum and Buzz

Transformer isolation breaks ground loops between your instruments and the console, a common source of hum with electrically powered gear. Isolated XLR connectors, a military-spec circuit board, and a ground lift switch help keep your system quiet.

Setting Up the ProD2

Connect the left and right outputs of your keyboard or playback device to the 1/4-inch inputs, use the thru jacks to feed a stage amp or monitor, and run XLR cables from the outputs to your mixer. Engage the -15 dB pad for hot signals and the ground lift if you hear hum.

What to Pair With the ProD2

Pair the ProD2 with quality instrument and XLR cables, a mixer or stage box, a keyboard stand, and a Radial ProDI for mono instruments.

Ideal for Keyboards and Playback

The ProD2 is a go-to DI for keyboard rigs, backing-track computers, DJ setups, and media players in churches and conference rooms, delivering a stereo signal free of hum over long cable runs.

Built Radial Tough

A 14-gauge welded I-beam inner chassis protects the circuit board from torque stress, the book-end shell protects switches and connectors, and a no-slip rubber pad provides electrical insulation and keeps the DI in place.

Passive vs. Active DI

Passive DIs like the ProD2 need no batteries or phantom power and excel with line-level sources such as keyboards and playback devices. Active DIs are often a better fit for passive pickups with very low output.

Why Use a DI Box?

Keyboards and playback devices produce unbalanced signals that pick up noise over long cables. A DI converts them to balanced, low-impedance signals that travel cleanly to the mixer, matches levels to the mic preamp, and isolates the stage from the console to stop ground loops.

Tips for Best Results

Keep the instrument cables between your source and the ProD2 short, and use the XLR outputs for the long run to the console. Label left and right channels on the stage box, start with the pad off, and use the ground lift whenever hum appears.
