The 9 Best Stereo DI Boxes (2023 reviews)

The pyle stereo di box's material feels more premium than its price would suggest. The box is constructed of very sturdy metal. It reduces stage clutter, noise and signal loss from long instrument cable runs. It provides attenuation to interface a line or instrument output with a balanced microphone input. You can even plug your guitar, bass or keyboard amp’s speaker output into the pdc22, which can handle ratings and still deliver a perfect signal.

The purpose of this box is to convert unbalanced to balanced for noise reduction. It is great for any stereo. It is made of metal, feels sturdy, and the connectors fir snug. They also allow you to set input levels via a switch just in case your input is hot.

Best For computer: Mackie Stereo DI Box

Buy on Amazon

Next on the list, we've got yet another box that manages to win our hearts. It's the mackie stereo di box and it's widely considered as one of the best convenient box you can buy. This is an “active” DI box, meaning that it needs a battery or phantom power from the mixer. This device translates input from each 1/4" input to the associated XLR output. It feels like a solid little box that is well made. If you are using your own board, this is a cool piece of hardware and has a lot of nice features like the 15db pad, the ability to combine two sources or use the second 1/4" jack as a "through" jack.

This last feature is actually very useful not only for driving an amp onstage as a monitor while the low-Z signal goes to the mixer. It is great with no buzz or hum.

Why We Like This:

More buzzing sound from the computer through the mixer console
Tons of flexibility, small enough to fit on a pedal board, and quiet
Lot of satisfied buyers

Best For Ipad: ART Stereo DI Box

Buy on Amazon

The art stereo di box is satisfactory and appropriate and fits well with your daily purpose. When you connect the DI Box to a PA amplifier that provides phantom power for mics, the DI box can be powered by that phantom power. It converts various high impedance balanced and unbalanced inputs (microphone xlr connections, 1/4" line level phono plugs like a guitar, etc) to a standard balanced low impedance signal output. It does not supply phantom power to a condenser mike through the input port.

This is exactly like two separate single channel DI boxes, so if you've got the right splitters, you could use it for a stereo input/output. It comes with a full line of vacuum tube preamplifiers and compressors that deliver unmatched warmth, tone and character. It has an extremely flat and wide frequency response and can handle high signal levels.

Why We Like This:

Very quite and lean sounding direct box
Well built and runs great off of the phantom power from the mixer
Works on 9v battery or phantom power

Best situation type: Radial Engineering Stereo DI Box

Buy on Amazon

The radial engineering stereo di box's material feels more premium than its price would suggest. This box is part of radial jdi line that uses genuine jensen transformers for soft and subtle sound curves. It features exceptional signal handling with virtually zero phase shift or harmonic distortion, while remaining linear across the entire audio spectrum. It also has a polarity flip switch for each output to eleminate hum caused by import sound devices. It can work as two standalone mono boxes.

The front of the unit has one XLR output and one XLR input for each channel. There's a "mix button" that will allow the thruput line to become a second input line for mixing stereo signals to mono. It does this thru a transformer and (without getting into the physics) as such protects both lines from one another while at the same time elemintaing the possibility for problematic ground loops.
