Type 10 Direct Box

The Type 10 DI box combines exceptional ruggedness and versatility with an advanced design that sets a new standard for pure performance.



The Type 10 delivers your sound with 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.

  • Lowest distortion
  • Lowest noise

Precise performance

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

Virtually indestructable

Armored inside and out, with a molded core wrapped in an extra thick architectural aluminum housing, our DI boxes are virtually indestructable.

Direct Box Phase Inversion

Most DIs do not handle high signal levels with grace. Many use old and cheap op amps plagued by poor overload characteristics; most notably, phase inversion.

Phase inversion is where the op amp output abruptly transitions from one supply to the other on overload. This leads to countless non-linear artifacts, to put it mildly. In fact, phase inversion will even mask the original fundamental frequency of the source.
