2DI4 Pentode Direct Box

2DI4, now in upgraded Mk.II version, is a dream come true for bass players, as well as guitarists who record direct and use an amp simultaneously. It can also be used to yield character to any string instrument with a pickup (like pedal steel!), to make keyboards sound warmer, even to improve the sound of music players. And because it has both line and mic level balanced outputs, which can be used at the same time, it can drive a variety of inputs.

As with the Creamer, a single pentode is the only gain stage. The high and low frequency boost circuits use high quality capacitors and inductors to impart fatness or top end to your signal in a very musical way. 

A buffered “thru” output enables a long cable connection with your amp, without a high end roll-off.

A special DI transformer brings the output down to mic level, to drive consoles. A balanced line level output is also there for direct recording. We think this is the absolute state of the art in direct boxes.

If you are a bassist, you may want to check out some 2DI4 threads on talkbass.com forums, as they have some very useful information regarding it’s use on stage or in a studio:

In the meantime… The 2DI4  has already hit Vancouver’s studios, clubs and players.
(this was posted back in 2012)

At the Warehouse studio, Boris dropped one off just as an important session was starting. They had already figured out their bass guitar recording setup so the 2DI4 wasn’t supposed to get much, if any use. But when they tried their trusted DI workhorse (yes, it’s the most famous one!), somehow the tone was a bit thin, plus there was a lot of noise…They switched over to DI box #2 (another famous unit). Dissatisfied again, they patched in the 2DI4, and just couple seconds after the first bass note was plucked, a few jaws dropped! Needless to say, it was the DI of choice for the rest of the session.

Now everybody and their dog wants one!
