Description The benefits of using a DI Box are substantial, and it is something every pedal user should have on hand. What does it do? It converts unbalanced signals, which typically use a 1/4″ jack, to balanced signals, which typically use XLR connectors. A DI (DI stands for direct input) is especially beneficial for longer cable runs; it allows for more length without noise due to the use of a low impedance XLR microphone cable. A 1/4″ unbalanced instrument cable has just 2 conductors, the center conductor and the shield. The centre conductor carries the positive portion of the signal and the shield carries the negative portion of the signal. This is why these cable are more susceptible to noise. The balanced XLR cable has 3 conductors, 2 to carry the positive and negative portions of the signal and a separate ground, which is the shielding. This provides far superior noise rejection. Low impedance balanced cable lengths can be much longer than unbalanced instrument cable lengths, which are functionally limited to the 20′ range. The Little Red Di Box also has a Ground Lift Switch that, when lifted, can eliminate ground hum when present. Still need to know more? For one, the sound guy will love you for using a DI Box, as it makes his job easier. Even if you typically use an amp, you may find that you are not loud enough at a particular gig (or worse…your amp meets its maker) and going straight to the PA can remedy the situation. In a word, INSURANCE. POWER The Little Red DI Box is a passive device requiring no power to operate. Dimensions: L 60 mm x W 53 mm x H 45 mm
