Countryman Type 85
Direct Interface Box

How do you send the purest warmest and most natural signal out of a high-impedance instrument to a balanced mic input at the console? Countryman's Type 85 Direct Interface box.

Reflecting the ultimate engineering and highest-quality materials the Type 85 DI Box adds nothing and removes nothing from the instrument's signal. No distortion. No electronic hum or buzz. No loss of dynamic range. It's the only active direct box that delivers such a clear strong warm signal to the mixer.

What's more its design is sleek compact and virtually indestructible and its 9V battery back up to phantom power helps ensure it will never lose power onstage. Countryman's Type 85 is hands-down the most valuable and cost-effective direct box on the market!


  • Connects any high-impedance instrument (including piano) to an XLR mic input
