Countryman DT10 active DI box; low distortion, low noise, high accuracy

Countryman DT10 (Type 10) Active DI Box

The Countryman DT10 (Type 10) is a virtually indestructible active DI box which delivers the lowest distortion, lowest noise, and highest accuracy of any direct box. The result is a clean, precise signal that is completely faithful to the original sound.

Precise Performance
Unmatched technical performance separates the Type 10 / 10S DI boxes from all competitors. The result is a clean, precise sound.

Virtually Indestructible
Armored inside and out, with a moulded core wrapped in an extra thick architectural aluminium housing, our DI boxes are virtually indestructible.
