The Crimson Audio Direct Injection Box gives you a rugged road-worthy DI with a smooth sound in a small footprint. This makes the Crimson Audio DI perfect for the studio and the stage.

The Crimson Audio Direct Injection Box features everything you need in a DI box, but in a convient compact size. You get two 1/4" TS connections, which either can be used as your input and Thru. These connect to a balanced XLR connector on the output, and features the much needed ground lift switch. While a ground lift is most often not needed in a studio, home studios may not have the best wiring and environments, and the stage is 90% trouble shooting. All of this is centered around Crimson Audio's own CT-121di transformer. The CT-121di is a precision wound, hum bucking design, that is housed in a mu-metal case which provides excellent noise rejection.

What We Think


The Crimson Audio Direct Injection Box is very well build and perfectly quiet. The ability to use either TS jack as the input or Thru is nice, and while as a studio engineer and musician I rarely need a groud lift - it is nice to have. Sonically the Crimson Audio Direct Injection Box has a slightly rolled off top end that presents a smooth sound. I tried it with several electic guitars and the Crimson DI always provided a smooth rounded sound. The buidl quality lets me know this thing will handle the road, so I have no doubt this will be a favorite for many musicians out there.
