What is a DI Box?

This piece of equipment is a tool that musicians use to assist in the balancing or increasing of the signals. It also can be used to isolate your guitar from any electronic interference being translated into the sound. 

This unit is used to be able to plug your instrument straight into a laptop or PA without losing signal quality. You can also use a DI box to eliminate electronic hum or buzz from faulty wiring in venues due to the inclusion of a balancing transformer.

What Purpose Does a DI Box Serve?

There are many things that these boxes do for the recording or performing guitarist. Knowing the jobs that this box can do will easily help you along with the process of making a decision that will elevate your performance.


The DI box’s primary objective is to take signals that are transmitted from an unbalanced connection like a guitar or other instrument through an electronic unit to produce a balanced signal emitted through an amp or PA system. 

Elimination of Noise

Units will come with a ground lift switch, which breaks the ground wire connection between the in and out. This, in turn, eliminates the noise from wiring and electronics.


Some will have phase switches that will switch up the positive and negative parts of the signal. This can help when using both guitar and microphone. 

Volume Control

Stabilizing and balancing the input signal can help even out the volume levels. This will help the sound quality to be enhanced, leaving the guitarist with a clear tone.

How to Choose a DI Box

You may not be familiar with the features and functions of a DI box, and even if you are, you may not know what to look for in a good unit. So, to help you with this, we have gathered together a list of the features we think you should be considering as you make this important decision.


There are two styles of DI box: passive and active. Knowing which one you are looking for will help narrow down your selection of choices.


These boxes are able to be used without any external power source. These types of DI boxes are best to be used with instruments that have active pickups.


This version uses phantom power or battery or a combination of both. They are best used with instruments that use active pickups and/or are electric.

I/O Ports

When finding the right option, you will want to find the one that has the right amount of inputs and outputs for your needs. This will be dependent on how many instruments or devices you will be using.


Thinking about your intention in use will help dictate the size you need. If you are using it in a studio, a larger option may be just fine. Whereas if you are a gigging professional, then you may want a lightweight, compact option for better portability.

Why it Stands Out to Us

Aspects to Consider Before Buying

Looking at the durability of the options is a crucial consideration. Looking at what material and the quality of that material is an aspect that will be important.


Though most artists may only need one channel, for those that want more versatility, multiple channels are the better option. So, knowing what you plan to pipe through this box will be helpful in the decision-making process.


Considering how much you are willing to spend can be crucial to the choice as well. Knowing the amount of money you have available and your must-haves when looking at the DI boxes available will allow you to choose the right one for you.


Knowing what you intend to use the box for can be an aspect that plays a part in finding the right option for you.

Cautious Considerations to Keep in Mind

You will need to think about what venues that you will be playing in. Choosing the wrong option for the places you will be playing could be detrimental to the efficiency and use of this tool.


You will need to pay attention to the instruments that you are using as well as the devices. Older models may not be compatible with every model available to you. So, if you are using older equipment, you will need to find ones that are compatible with them specifically.


There are many types of transformers available, and paying attention to how they are mounted in the unit can be an important aspect to pay attention to.

People Also Ask

If you still have a question that haven’t been answered, take a look below to see if it is one of our most frequently asked questions.

Do I Need an Active or Passive DI Box?

The most significant difference between passive and active is that passive does not need any power to be used. Passive boxes are a transformer that uses the internal components to match the impedance and balancing with no other significant jobs.

Does a DI Box Boost Signal?

DI boxes do not boost the signal. In fact, they are specifically designed to manage balanced signals from low to medium levels and balance the signals within it. There is absolutely no gain added with the use of the DI box.

Do DI Boxes Need Phantom Power?

They don’t need phantom power to be used. Passive models do not require any form of power source to operate.

Can You Use a DI Box Backwards?

A passive model can be used in reverse; however, the active variety cannot. When using the passive model in reverse, you have to pay close attention to the signal levels. If you are not cautious, you can easily overdrive the DI.
