Review: Well worth the money - - Bought to match the unbalanced output of a TV with the balanced input of powered monitors. Yes, you can ground one side, but you also lose 14 dB of gain when feeding a balanced input with an unbalanced source. A passive device, so no power needed. Also isolates the units so that you don't get the hum of a ground loop. A good solid metal case. Well worth the money.
Review: EXCELLENT 5 STAR DUAL PORT DIRECT BOX! ⭐⭐⭐⭐⭐ - As a Professional Stage & Lighting Technician, Sound & Studio Engineer, Professional Audio-Visual Production Specialist and Musician I cannot stress the importance and necessity of having a good Direct Box in your kit! I think most of the people reading this know what a direct box is used for and how it's utilized in a professional application! However, in case someone is just starting out and not too familiar with what a direct box can do here's a quick synapses!! A direct box can take an unbalanced signal from let's say an Acoustic Guitar (TS) and allows it to connect via a Balanced Connection (XLR) directly to your mixer/board! If you refer to the pictures that I've attached to this review you'll see a typical application for a direct box! Here's where it gets better! If you have Two Instruments that utilize unbalanced outputs such as a Keyboard or in my example an Acoustic Guitar you can now plug BOTH instruments into this DBMKII because this unit is actually Two (2) Direct Boxes in one! The convenience of this unit alone is well worth it because now you can carry one less Direct Box in your Kit! Anyhow in my example & test with my Taylor Acoustic Guitar this DBMKII unit performed exceptionally well! The audio quality was super and there wasn't any other strange or unwanted characteristics which this unit produced in my test! The quality of construction of this unit is Excellent as well!! IT'S AN ALL METAL CHASSIS WHICH WORKS GREAT FOR TOURING PROFESSIONALS LIKE MYSELF! I LOVE EQUIPMENT WITH METAL CHASSIS BECAUSE OUR ROADIES & TECH TEAM HAVE A TENDENCY TO THROW THINGS AROUND AND THIS UNIT WILL SURELY WITHSTAND THE RIGORS OF BEING ON THE ROAD!! I'm obviously NOT recommending that you throw this around in just merely pointing out that because it's metal it has a better chance of actually surviving a Tour! Overall I LOVE this unit! It's super convenient with the Dual Channels and the fact that it's in essence Two (2) direct boxes in one! I love it and cannot wait to take this on the road this spring and summer! I'm definitely going to have it at Coachella and Stagecoach and everywhere else we end up going! I'm rating this Unit 5 Stars based on Great Audio Quality, Ease of Use, the fact that it's 2 Direct Boxes in One, All Metal Chassis and simply a Great Unit!! ⭐⭐⭐⭐⭐

## Features

- ✅Perfect for all live sound permanent installations, club, church and practice PA systems, monitor systems, home and project recording studios, karaoke and DJ sound systems.
- ✅Enables the connection of any unbalanced audio source signal (such as from an electric instrument, keyboard–even from an amp speaker output) to any balanced input (such as that of a mixer).
- ✅Parallel Output allows simultaneous connection to 2 separate inputs (such as to an amp and mixer). Translates high-impedance instrument outputs into low-impedance balanced signals or balanced low-impedance balanced signals into unbalanced outputs.
- ✅Converts unbalanced +10dB DJ mixer signals to balanced line level signals, enabling both easier interfacing with consoles and longer cable runs.
- ✅Enables multiple keyboard setups plugged into an instrument amp to be directly input to a console mixer by connecting the speaker outputs of the amp to the console input through the DB-MKII, thus eliminating the need for a direct box on each.
- ✅3-position input attenuation switch (0dB, -20dB, -40dB) facilitates proper output signal levels for optimum level matching to connected equipment. Switchable ground lift eliminates ground loop continuous reliability.

### ⭐⭐⭐⭐⭐ Surprisingly sturdy, works well!
*by K***T on May 1, 2025*

Just got back off the road. Picked up this inexpensive DI box as a backup to my normal DI. I'm glad I did - old faithful quit on me halfway thru the shows. First impression - this thing is well made, solid metal, and built like a tank. It added no new noise to my signal chain (important for acoustic instruments), was as easy to use as my normal DI, and compared to what I paid for old faithful, it's HALF THE COST. I can't complain at all and plan to get another as a backup to my backup.
