Description
Overview
The Warm Audio Transformer-Balanced 2-Channel Active Direct Box is a professional-grade stereo DI solution engineered to bridge the gap between high-impedance instruments and mic-level inputs. Designed specifically for stereo rigs, this unit ensures that keyboards, synthesizers, and complex pedalboards maintain their tonal integrity while delivering a clean, balanced signal to mixers, audio interfaces, and PA systems.
At the heart of this unit are custom-wound CineMag USA transformers, which provide the classic warmth and stability required for high-fidelity recording and live reinforcement. By converting unbalanced instrument signals to balanced mic-level signals without degradation, it eliminates the noise and signal loss typically associated with long cable runs.
Key Details
- Premium Signal Path: Features custom-wound CineMag USA output transformers and top-quality Class-A components with gold-plated traces on the circuit board for maximum conductivity.
- Flexible Power Options: Operates as an active DI via 48v Phantom Power for increased headroom and signal boost, but can also be used passively for high-output sources.
- Precision Level Control: Includes a variable pad ranging from -3dB to -30dB, allowing you to dial in the perfect input level for your preamp or console.
- Noise Management: Equipped with a ground/lift switch to instantly eliminate ground-loop hum and interference.
- Rugged Build: Housed in a durable aluminum chassis designed to withstand the rigors of touring and studio environments.
Use Cases
- Stereo Synthesizers & Keyboards: Preserve the wide image and frequency response of stereo synth patches when plugging directly into a mixing console.
- Complex Pedalboards: Ideal for guitarists using stereo modelers or spatial effects processors that require a balanced connection to the Front of House (FOH).
- Low-Output Instruments: Utilize the active circuitry to boost weaker signals, ensuring they hit your preamp at an optimal level without adding noise.
- Studio Recording: Use as a high-end interface between outboard gear and your audio interface to achieve a “transformer-colored” professional sound.
Installation
Setup is straightforward and requires no permanent installation. Connect your instrument’s output to the input jacks using standard TS cables. Connect the balanced outputs to your microphone preamps or mixer using XLR cables. For active operation, engage 48v Phantom Power from your mixer or interface. If you encounter a hum, toggle the ground/lift switch to isolate the signal.
Compatibility
- Input Compatibility: High-impedance (Hi-Z) instruments including keyboards, synthesizers, electronic drums, and guitar processors.
- Output Compatibility: Any standard XLR microphone input, mixer, or audio interface.
- Power Requirements: 48v Phantom Power (for active mode); no power required for passive mode.
