DI Boxes
What is a DI Box?
A DI box, or Direct Injection box, is a device used to connect instruments directly to a mixing console or recording interface.
Do I need a DI Box?
If you are playing an instrument like a keyboard or a semi-acoustic guitar, especially in a live or recording set-up with long cable runs, then a DI Box will be necessary.
What does a DI Box do?
Impedance Matching: DI boxes convert high-impedance signals from instruments to low-impedance signals suitable for mixing consoles.
Signal Balancing: They help to balance the audio signal, reducing noise and interference over long cable runs.
Ground Lift: Many DI boxes include a ground lift switch to eliminate hum caused by ground loops.
Level Adjustment: They can adjust the signal level to match the input requirements of the mixing console.
What are the different types of DI Boxes?
Passive DI Boxes: These use transformers to convert the signal and do not require power. They are typically used with high-impedance sources.
Active DI Boxes: These require a power source (usually a battery or phantom power) and are often used with low-impedance sources for better sound quality and signal strength.
How much does a DI Box cost?
Prices start from £10, and you can pick up a decent mid-range DI Box for around £178. Expect to pay up to £1,899 for a top specification professional device with multiple features.
