Essential Information on the 2U Push-Pull Tube Mic Preamp
- Push-pull tube architecture for controlled harmonic saturation, excellent headroom, and solid dynamics.
- Gain in 2 dB steps from +10 to +70 dB for fine and repeatable adjustment during recording.
- Variable mic input impedance (600 Ohm / 1.2 kOhm / 2.4 kOhm) to tailor the "character" and matching with your microphones.
- High-impedance front panel instrument DI input (>1 MOhm), ideal for guitars, basses, and synths.
A Preamp Rooted in the Tradition of Classic Studio Channels
Designed in the spirit of classic transformer-based units, this tube preamp emphasizes musicality and precision. The push-pull architecture reduces noise and improves hum rejection while delivering the warmth sought by modern sound engineers. It positions itself as a "controlled color" solution balancing transparency and character.
Who Is It For and What Are Its Uses?
Perfect for lead vocals, acoustic guitars, drum overheads, and live bass, it suits both professional studios and demanding home studios. Producers, premium podcasters, and content creators will appreciate the gain reserve, consistent stepped control, and extended frequency response for clean and detailed recordings.
Features Designed for Modern Recording
Uncompromising Signal Control
The -20 dB pad placed before the transformer protects the input stages and preserves sonic texture on strong sources. Peak indicators help target the sweet spot, whether capturing a clean signal or a slight harmonic push.
Maximum Adaptability
Adjustable input impedance optimizes the response of dynamic, ribbon, and condenser microphones. The +48V phantom power ensures compatibility with condenser mics, while the front-panel DI input avoids repatching and maintains instrument clarity thanks to its very high impedance.
Smooth Workflow
Rear XLR inputs/outputs easily integrate into a patchbay. The 19-inch 2U rack format facilitates installation in any rack, whether in fixed control rooms or mobile setups.
