Professional Passive Direct Box for Balanced Audio Signals

The Professional Passive Direct Box is a high-quality interface designed for connecting instrument, line, or speaker-level signals to a mixer or other balanced input via a high-performance audio isolation transformer, ideal for live sound and recording applications. It converts the high-impedance, single-ended 1/4″ input into an isolated balanced low-impedance signal output, ensuring clean and neutral sound with a wide variety of signal sources and over long signal runs in high-noise environments.

Product Highlights

• Reliable passive interface for balanced audio connections
• Handles instrument, line, or speaker level signals with ease
