Direct Boxes (DI Boxes)
DI (Direct Injection) boxes are audio devices used to connect electronic instruments, such as guitars and keyboards, directly to mixing consoles, amplifiers, or PA systems. They convert high-impedance, unbalanced instrument signals into low-impedance, balanced signals, reducing noise and signal degradation over long cable runs. DI boxes ensure clean and reliable audio transmission, making them essential tools for achieving optimal sound quality and consistency in live performances and studio recordings.
