The 5 Best Professional DI Boxes (2023 reviews)

Behringer has been making feature-packed box for years, thanks to a combination of clever design and high-end materials. While they're not amazing or mind-blowing (this IS just a passive DI box, mind you), they're surprisingly quiet and solid. The product feels really nice quality and the size is really nice for bringing it with you at all times in a guitar case. The advantage is this direct injection box converts a 1/4 inch guitar cable line out to a microphone cable xrl balanced line giving you more to work with as far as incoming signal on the recorders input provided it accepts a common stage mike cable.

This load can be a speaker or speaker load simulator, basically what you would normally connect to the amp. It does a great job of eliminating line level hum/noise. When the ground lift is enabled, the hum is pretty low and having a good strong output from the source helps keep the noise floor low. It does not completely remove the noise. This is a great unit for connecting your laptop to your mixer and would easily recommend this witnkit reservations.

Why We Like This:

Very nice device, no hum or buzzing when connected, just clean tone
Works flawlessly for electric bass/acoustic-electric guitar
Good brand reputation

Best For home recording: Donner Professional DI Box

Buy on Amazon

Compared with other box in this category, the donner professional di box has a convenient design. This is a fantastic DI box, perfect for independent recording. It provides impedance and signal matching for the direct connection of instruments to mixers and amplifiers. The input is connected to a single coil, and this is placed next to 2 coils which connect to the XLR output. It comes with tartar sause and it is great as a dual outpt. The ground lift switch does what it’s supposed to and completely removes the hum.

The output impedance of the di box is directly correlated to the number of windings in the output coils, but only slightly correlated to the impedance of the input coil, so there is no need for a switch or a separate coil to accept different inputs. This direct box is durable, sounds great, and won't break the bank.

Why We Like This:

Well made and built pretty solidly
More static buzz and no more bass amp
Good investment for long term

Best For streaming of radio station: ART Professional DI Box

Buy on Amazon

Next on the list, we've got yet another box that manages to win our hearts. It's the art professional di box and it's widely considered as one of the best convenient box you can buy. This direct box is incredibly small considering that it houses two channels. It is used for a microphone but it has no need for it. The ground lift switches let you totally separate the input and output signal grounds, when appropriate, to isolate two systems, thereby reducing hum and ground-loop noise. There are a lot of buttons to select pad levels, ground lift, etc. It also has a phase invert on each channel.

While a number of DI boxes are available this one is simple, has a filter for use on digital devices others don't, and doesn't require phantom. The input attenuator switches allow for a wide range of signal levels and the input thru jacks allows for tapping off of your signal chain.

Why We Like This:

Multi level padding, ground lift, sturdy case
Cut filter to eliminate possible interference from digital devices
20 db attenuators on each channel which can also be stacked for
