PROEL D10P Passive Direct Injection Box 1/4 Inch Jack
Passive DI box with transformer for clean signal. Eliminates hum and ground loops. No power needed. XLR and Jack.
The PROEL D10P Passive Direct Injection Box is a professional-grade audio solution designed to connect high-impedance, unbalanced sources to a mixer's low-impedance, balanced input. As a fully passive unit, it requires no external power, such as phantom power or batteries, ensuring reliable operation in any setting. The built-in transformer provides full galvanic isolation, which effectively eliminates ground loops and cancels common-mode noise like hum, delivering a clean and interference-free signal path.
The D10P features a 1/4 inch unbalanced input and a link output for daisy-chaining multiple signals, while the balanced XLR-M output ensures a secure connection to mixing consoles. With a high input impedance of over 250k Ohms (without PAD) and a maximum input level of +20dBu, it handles a wide range of instruments and line-level sources. The switchable PAD (-20dB) and GND LIFT controls offer flexibility to match various signal levels and prevent ground-related hums.
