Warm Audio WA-DI-A2: Professional-Grade Stereo DI Performance

High-end stereo direct injection is accessible for any stage or studio setup with the Warm Audio WA-DI-A2. Featuring transformer-balanced signal paths, dual-channel flexibility, and selectable active or passive operation, this model ensures your instrument's sonic character remains intact when routed to mixers or recording interfaces. The WA-DI-A2 is engineered for challenging tasks, handling everything from keyboards and synthesizers to stereo guitar rigs and bass.

Standout Features for Unmatched Clarity

Unique to this model is the use of custom USA-made CineMag transformers for each channel, which provide impressive noise rejection and preserve the instrument’s natural sound. The circuitry allows active/passive switching on each channel for greater adaptability, while a rugged aluminum chassis ensures reliability on tour or in the studio.

Signal Integrity and Flexible Connectivity

Maintaining a pure, balanced signal is crucial in professional audio. The WA-DI-A2 achieves this with advanced technical specifications and features tailored for versatile stereo setups.

• Inputs: 2x 1/4” TS, 2x 1/8” (3.5 mm) TS — guitars, keyboards, synths, or drum machines can be connected in stereo or mono for flexible integration.
• The balanced XLR outputs (2x, 600 Ohms) deliver mic-level signals directly to mixers or interfaces, minimizing interference in live or studio contexts.
• Variable Pad: -3 dB to -30 dB — users can set the signal level for any instrument, preventing overloads in complex setups.
• Phantom Power: 48 V operation in active mode — consistent output and reliable performance over long cable runs are supported.

Technical Precision for Demanding Sources

This model’s technical design delivers low distortion and a broad frequency range, which musicians and engineers value for professional sound quality.

• Frequency Response: 10 Hz – 100 kHz (±0.5 dB) — every nuance, from bass to treble, is preserved for true-to-source audio.
• Input Impedance: 1 MOhm — compatible with both passive and active instruments for universal use.
• Total Harmonic Distortion: 0.003% (active) — keeps the signal path transparent and free from unwanted noise.
• Dedicated polarity/phase reverse switches instantly address phase and wiring issues for each channel.

Adaptable and Rugged for Stage or Studio

Adaptability for a range of audio sources is achieved through its robust aluminum enclosure, which withstands the rigors of touring. The ground lift switch for each channel counteracts hum and buzz, while amp/instrument modes and thru jacks optimize routing for advanced configurations. Dimensions are 140 x 127 x 71 mm, and at just 0.8 kg, this DI box remains compact without sacrificing durability.
