Warm Audio WA-DI-P2 Passive Stereo DI Box for Pristine Signal Integrity

The Warm Audio WA-DI-P2 sets a new benchmark for passive stereo DI performance, whether on stage or in the studio. Thanks to USA-made CineMag transformers, this model converts instrument-level signals to balanced mic-level outputs with fidelity and no unwanted coloration. Musicians can rely on the WA-DI-P2 to preserve the full tonal character and dynamic range of their guitars, keyboards, synths, or basses when connecting to professional audio equipment. Premium components combined with rugged construction make it indispensable for engineers and performers who demand reliability in every session. Expect pro-level clarity and flexibility exactly where it matters most.

Standout Features: CineMag Transformers and Advanced Controls

Distinguishing the WA-DI-P2 is its use of custom-wound CineMag transformers for each channel—components more commonly found in higher-priced DI boxes. Among its advanced features are per-channel ground lift and phase reversal switches, plus a variable pad for seamless adaptation to varying signal levels and sources.

Technical Performance—Signal Handling & Connectivity

Careful signal routing is crucial when integrating instruments into professional audio systems. To ensure a transparent, noise-free path for any stereo setup, the WA-DI-P2 offers:

• Input Impedance: 1 MΩ — compatible with passive and active pickups
• Output impedance is 600 Ω (mic level), making it ideal for long cable runs and interfacing with preamps.
• Frequency Response: 10 Hz–100 kHz ±0.5 dB — preserves a wide range of detail for today's instruments
• THD: 0.01% (20–50 Hz), <0.004% (50 Hz–20 kHz) — delivers near-transparent signal in demanding conditions
• Variable Pad: -3 dB to -30 dB — adjusts for signals from synths, amps, or hot outputs

Practical Benefits—Studio & Stage Flexibility

For real-world use, robust features address challenges in both live and studio environments. Separate ground lift and phase controls per channel simplify ground loop and phase alignment for stereo rigs or multi-instrument setups. Its compact, sturdy housing enables the WA-DI-P2 to fit comfortably in road cases or permanent installations.

• Each channel includes ground lift to eliminate hum from ground loops
• Phase Reversal: Yes, per channel — ensures phase alignment in complex stereo or multi-mic arrangements
• Instrument/Amp Out Switch: Yes — offers routing flexibility for direct instruments or guitar amp outputs

Dimensions & Build Quality

Built for durability, the WA-DI-P2 features compact dimensions and a robust metal enclosure. It easily fits pedalboards or racks and provides shielding against interference.

• Dimensions: 127 x 140 x 71 mm
• Weight: 0.78 kg
• The rugged metal chassis is engineered for heavy-duty, everyday use.
