Warm Audio WA-DI-P2 Transformer- Balanced 2-channel Passive Direct Box

When stereo signal routing needs to remain simple and reliable, the Warm Audio WA-DI-P2 passive stereo direct box provides two channels of direct injection without requiring external power. Designed for keyboards, synthesizers, pedalboards and other stereo sources, it converts instrument- and line-level signals to balanced outputs while maintaining the natural dynamics of the source. Built around CineMag USA transformers, this passive stereo DI box delivers consistent output, low-noise performance and stable signal integrity for both stage and studio applications.

Transformer-Based Circuit for Reliable Signal Conversion

The WA-DI-P2 uses a transformer-balanced design to maintain signal integrity from input to output without active circuitry. This approach provides strong isolation and noise rejection while preserving low-frequency detail and high-frequency clarity. Well suited for higher-output sources such as keyboards, drum machines, playback systems and modelers, it delivers a consistent, balanced signal ready for mixers, audio interfaces and PA systems.

Dual Channels Support Stereo Instrument Setups

With two independent channels, the WA-DI-P2 is designed for stereo rigs that require consistent performance across left and right signals. It supports stereo synthesizers, dual-output pedalboards and acoustic-electric instruments without introducing additional routing complexity. The passive design allows for straightforward integration into existing signal chains while maintaining phase consistency and overall balance.

Durable Passive DI Box for Stage and Studio Use

Housed in a rugged aluminum enclosure, the WA-DI-P2 is built for dependable use in live and studio environments. A variable pad from -3dB to -30dB allows controlled signal attenuation, while a ground lift switch helps reduce hum in complex setups. Compact and reliable, the Warm Audio WA-DI-P2 passive stereo direct box provides a practical solution for clean, balanced stereo signal routing.
