Additionally used to record a clean signal of your instrument for later reamping, while allowing you to use longer cables on stage without noise or interference. Key features include Ground Lift to reduce noise, Pad for reducing the signal level and Thru/Bypass for routing signals directly to stage amplifiers while sending them to the PA system.
Gear4music offers a comprehensive range of both active and passive direct boxes from leading brands Palmer, ART, Radial and more.

About DI Boxes
D.I Boxes (Direct Injection), are essential tools in both live performance and studio settings. Their core function is to convert unbalanced or high-impedance instrument signals, like those from electric guitars and basses into balanced signals that are compatible with professional audio equipment. A bass D.I box and guitar D.I box let you directly connect to a mixing console's microphone input without loss of sound quality while rejecting interference and noise.
There are three main functions of a D.I box. Firstly, they match the output level of electronic musical instruments to a microphone level. Secondly, they convert unbalanced signals into balanced ones, which is vital since most professional audio setups are designed to handle balanced inputs. Lastly, D.I boxes effectively suppress ground loops and humming noises, which can detract from the clarity and quality of the audio signal.
There are two main D.I box types: Passive and active. Passive D.I boxes are straightforward, non-powered devices that work well with instruments that already have a high output level, such as bass guitars or DJ equipment. Alternatively, active D.I boxes require an external power source, typically 48V phantom power, and are ideal for low-level signal instruments like acoustic guitars. As a rule of thumb, if the input source is passive, use an active D.I box, and vice versa.
DI Boxes FAQs
What does a D.I box do?
A D.I box converts the unbalanced, high-impedance signal from an instrument to a balanced, low-impedance signal. This conversion reduces noise and eliminates any ground loops and buzzing both on stage and in the studio.
Do you need a D.I box with an amp?
You do not need to use a D.I box when connecting an electric guitar or bass guitar to an amplifier. Amplifiers feature very high input impedance, capable of accepting low-level instrument signals. A D.I box will be needed when using professional equipment such as mixers or audio interfaces.
What happens if you don’t use a DI box?
If you do not use a D.I box, you can experience noise and interference, especially with high-impedance instruments like guitars and basses. A DI box aids in solving these issues by balancing the signal, allowing for longer cable runs without loss of quality or introduction of noise.
