A high-quality, passive direct box that uses 2 proprietary custom-made transformers, one for each channel, for both impedance conversion and isolation. Linear from 20Hz-18kHz, with low distortion and virtually zero phase distortion makes it perfect for live or studio performances. Because of the transformer isolation, problems such as hum and buzz caused by ground loops are eliminated, making it very easy and hassle-free to use. Features include 1/4" thru/input, -15dB pad, and ground lift protected from damage by a protective front panel. Heavy-duty construction, baked enamel finish, and 600ohm balanced output. 3" x 5"..

5.0 out of 5 stars This thing is a Tank.
Reviewed in the United States on March 1, 2023
Verified Purchase
I have to say, this DI box is an absolute powerhouse. It's built like a tank and can withstand just about anything you throw at it. Whether it's being jostled around in a gig bag or dropped on the floor, this DI box just keeps on working.

What's even better is that everything about this DI box just works. The sound quality is fantastic and it does exactly what it's supposed to do - take an unbalanced, high-impedance signal and convert it to a balanced, low-impedance signal. I've used it for everything from recording to live gigs, and it's always performed flawlessly.

But what really sets this DI box apart is its durability. It's probably the best in the industry, and I've seen firsthand just how tough it can be. It's been dropped, and stepped on, but it still keeps on working like a champ.

Overall, if you're in need of a DI box that's incredibly durable and reliable, this is definitely the one to go for. It's built to last, sounds great, and just does what it's supposed to do. Highly recommended!

5.0 out of 5 stars Solid - we use 3 of these live - just bought a fourth today.
Reviewed in the United States on May 1, 2014
Verified Purchase
Our band has played around 8 shows in smaller clubs within the last year. We use 3 of these mounted in the J Rack (sold separately). These DI's are built like a tank, no hums, no problems. I almost forget we have them because we've never had an issue. I just bought a fourth today as we are going to add a few more outputs to the FOH.

In our setup, we have multiple outputs coming from a MOTU 828mk3 rackmount sound card and use these to convert to XLR, remove hum, and protect the audio device from any accidental phantom power from the mixing desk.

While everything routes through the sound card (so that's your true source), we essentially have keyboards, guitars, vocals, and our backing tracks all coming through these. Never heard anyone complain about tone.

The sound guys at the desk are always happy to see us roll up with our own DI's. Normally they have 1 or 2 if you are lucky at a small club.

Note: I don't have experience with any other DI because every review I read said to go with these. I have no reason to look any further.

5.0 out of 5 stars Church Sound System - NO BUZZ / HUM... quiet as a church mouse :)
Reviewed in the United States on May 2, 2018
Verified Purchase
Our church recently remodeled, and replaced our acoustic drums with electric drums. The size of our sanctuary just couldn't handle acoustic very well (too small/loud). The problem was, once we hooked up the electric drums we had an issue where they would periodically "clip" (pop in the speakers) when hit harder. This didn't seem to be a consistent repeatable thing, it just kept happening consistently-random. To avoid this, we had to pull the drum kit volume down to 3 or less (Default is 13).
Additionally, there was this TERRIBLE BUZZ in the speakers. NO matter what volume level you put the drum kit on, the buzz was still there (Same level). When we pulled the drum volume down on the mixing board, we could reduce the volume of the buzz, but not eliminate it altogether, and then, all the other instruments/vocals were overpowering the drums.

So i did some research and concluded that we must be experiencing a "Ground Loop". After reading reviews on this product, i though i would give it a try. I installed this between the drum kit and the snake. When i powered on the sound system, i was shocked that there was NO SOUND. No buzz, no hum, no noise of any kind. it didn't even sound like i had turned anything on. Our sound system has NEVER been that quiet, even before the remodel. My first thought was "Man, this thing isn't working, now i have NO sound". As i walked toward the box to start trouble shooting, it occurred to me that i should at least TEST the drums first. Guess what, they WORKED. The box was just THAT GOOD. Praise God. Additionally, this also seemed to fix the Popping / Clipping volume issue we had previously as i can now put the drums back on the default volume level of 13 with no issues.

5.0 out of 5 stars Best for unbalanced connections from a TD-30
Reviewed in the United States on April 26, 2024
Verified Purchase
Used for two main unbalanced outputs to a PA to produce a stereo field live. Voltage drops to microphone level, which really cleans up the sound enabling low impedance transmission.

Compared to a much cheaper version, the sound was noticeably better. Worth the money!

4.0 out of 5 stars solid, dependable direct box. Great for stereo instruments
Reviewed in the United States on July 19, 2010
Verified Purchase
Ive been using these direct boxes for ~ 4 years. I find them to be very solidly constructed, & low noise. Because they are 2 channel, they are particularly handy for stereo instruments like keyboard, or guitar through stage effects processors. Ive used other cheaper direct boxes, but eventually have had issues with noisy connections, switches, etc.
