As shown in the picture, connecting a DI box is simple. There are several benefits of using a DI box. One of the major benefits is that it allows you to use longer cables.
Normally, you get unbalanced output from instruments like guitars and keyboards. These unbalanced cables can not be used for more than 5 meters long. If your mixer is more than 5 meters away from your instruments, you must use DI boxes to connect all your unbalanced cables to the mixer.
Di boxes will reserve unbalanced input and provide you with balanced output. You can connect this balanced output to the mixer using XLR longer cables or snake cables.
The other benefit is that DI Boxes can isolate your instruments from electrical interference. This helps you to avoid unnecessary noise, hum, or buzz.
Moreover, by using DI boxes, you can avoid losing the audio quality that is produced by your instruments. When you use longer cables that are unbalanced, you will drop a significant amount of sound quality.
Therefore, our advice is to use DI boxes for all the unbalanced instruments.
