The DI Box that Rocks

By Michael

from Thousand Oaks, CA

This box is rock-solid and I am using it for my keyboard rig. While it may seem a little pricey, this is something that will last for decades. I have a similar non-stereo one from back in the '80s that still works great. Very pleased so far...

Perfect for Keyboard Rig

By Craig Mayhle

from Seattle WA

This stereo DI box is just what you need for your live keyboard rig. I run two keyboards through a small sub mixer, and then through this box to the FOH board. The thru's give me a sub-feed for a stage keyboard amp. Completely solved some ground loop issues, and I didn't even need to lift the ground switch on it! This unit is built like a tank.

Worth every penny

By David

from Staten Island, NY

I bought this to replace an inexpensive, noisy Behringer Ultra-DI. This DI is so quiet and rugged, and it passive circuitry perfectly matches the impedence of the my mixer. I'm driving two keyboards through this, and I bought it because a fellow musician uses it for his submixer which is about 100 feet from the main mixer.

Never worry about replacing a DI again!

By Cole

from New Jersey

I own several of these, not one has ever failed me. They are great for anyone from a beginner musician to a touring act. The build quality is fantastic you could step on it, throw it across the room, run over it with your car, and then light it on fire, and it would still work. A great investment for an individual or a company, as you will buy this and never have to worry about replacing it. I only gave it 4 stars because it lacks some of the nicer features its more expensive siblings have.
