Behringer DI22P Passive Stereo DI Box

The Behringer DI22P stands apart from typical DI boxes by offering two fully independent passive channels in a single rugged enclosure, making it an ideal solution for stereo keyboards, backing tracks, or dual mono sources without the need for active circuitry or phantom power. Its transformer-isolated design ensures clean signal transfer and effective elimination of hum and buzz caused by ground loops.

Highlights

• Passive stereo DI box with two independent channels
• Behringer OT-1 transformers for galvanic isolation
• Ground lift switch per channel to eliminate hum
• 3-position attenuation pad (0 dB, -20 dB, -40 dB) per channel
• Road-ready metal chassis with stackable design

In daily use

Connect unbalanced line-level sources such as keyboards, DJ mixers, or laptops to the 1/4" TS inputs. The DI22P converts the signal to balanced XLR for long cable runs to a mixing console or audio interface. The link/thru outputs allow you to feed a local amplifier or monitor without affecting the main signal. The ground lift switch comes in handy when dealing with noisy venues or multiple power sources. The passive design means no batteries or phantom power are required, ensuring reliable operation in any setup.
