Mackie MDB-2P Stereo Passive Direct Box
The Mackie MDB-2P is a stereo passive direct box designed to connect two mono instruments or a single stereo source to dual balanced microphone inputs. With ultra-low THD (0.002%), 128 dB dynamic range, and compact steel chassis, the MDB-2P delivers transparent, professional-grade audio conversion.Overview
The Mackie MDB-2P is a professional stereo passive direct box engineered to condition high-impedance, unbalanced stereo signals for entry into balanced microphone preamp chains. Ideal for keyboards, synthesizers, stereo instruments, and portable audio devices, the MDB-2P combines transparent audio fidelity with rugged construction suitable for studio and touring environments.
Key Features
- Dual 1/4" TS unbalanced inputs convert high-impedance signals to low-impedance balanced XLR 3-pin outputs
- Ultra-low total harmonic distortion (THD) at 0.002% (1 kHz) ensures transparent, artifact-free signal conversion
- Exceptional 128 dB dynamic range captures subtle details in quiet passages and loud peaks
- Frequency response of 20 Hz–20 kHz (±0.2 dB) covers the full audible spectrum with precision
- Input impedance around 140 kΩ; output impedance approximately 400 Ω for professional mic input compatibility

FAQ
Can I use the MDB-2P for a mono instrument?
Yes, you can use one input/output pair for mono operation, leaving the second pair available for another source if needed.
What is the ultra-low THD specification important for?
The 0.002% THD ensures that the DI conversion introduces virtually no audible distortion, preserving the original tonal character of keyboards, synthesizers, and other instruments.

Frequently Asked Questions
What audio sources work best with the MDB-2P stereo setup?
The unit handles either two mono instruments (guitar and bass, for example) or a single stereo source (keyboard, synthesizer, or computer audio), each routed to its own balanced XLR output.
How do the THD and dynamic range specifications affect sound quality?
The 0.002% THD and 128 dB dynamic range mean virtually no audible distortion and a huge headroom for quiet and loud signals, ensuring transparent professional-grade audio conversion.
Is the compact steel chassis durable for touring?
Yes; the rugged steel construction protects the internal circuitry and provides reliable performance in studios, live venues, and field recording without requiring external power or batteries.
Can I monitor both channels independently before sending to the mixer?
The MDB-2P converts stereo or dual mono signals to balanced XLR outputs; for individual monitoring, consult Procure.ae on system integration with your existing setup.
Does the unit include ground-lift control for hum elimination?
