Stereo Passive DI Box

The Klark Teknik DI 10P PRO is a passive direct box that accepts stereo signals and sums them to a single mono output. It uses a custom-built Midas transformer to maintain high headroom and signal integrity without requiring any external power supply.

For Line-Level Summing, Not Instrument Splitting

This unit suits engineers who need to connect stereo sources such as playback devices, keyboards or submixers to a mono XLR input on a console. It is not intended for users who require a thru output for on-stage amplification, separate channel routing or active buffering for high-impedance instruments.

Adjustable Levels and Ground-Lift Included

Independent level controls for both input channels let you balance the stereo mix before it reaches the summed output. A Neutrik XLR connector provides a secure professional connection while the Earth Lift switch removes ground-loop hum without additional accessories.

Questions about this item

What connectors must my stereo source have to plug into the DI 10P PRO?

The unit accepts a stereo source via its 1/8" TRS jack or a pair of RCA plugs, so your keyboard, media player or submixer needs one of those outputs.

Will the passive DI 10P PRO work properly if I keep using my older mixing console with standard XLR inputs?

Yes, the high-quality Neutrik XLR output delivers a balanced mono signal that any mixing console with a mic or line XLR input can accept without extra adapters.

How can I confirm the DI 10P PRO is passing signal cleanly after I connect it?

Set the independent level controls, engage the Earth Lift switch if hum appears, and verify a noise-free summed mono signal arrives at the console’s input meter.
