A direct box, or DI box, provides the facility for the direct insertion of an audio signal into a mixer or recorder. The PDC21 offers a variety of DI solutions for live sound and recording applications. You can connect all kinds of audio signals like guitars, keyboards, outboard signal processors. This unit enables you to tap off the signal from a guitar or bass guitar and pass the signal from the Para Output to the on stage amplifier without affecting the original sound. This can eliminate the need for mixing the guitar amplifier, which in many cases is preferable, especially with bass guitar.
The unit is also very useful for connecting unbalanced signals from sources like signals DJ and sub-mixers, effects processors and keyboards to a main PA or recording mixer. The PDC21 balanced output provides a clean signal at a low level as long as runs of cable are possible. Another benefit from a balanced connection is common mode rejection, which provides cancellation of unwanted sounds (hums and buzzes) while leaving the original signal pure.
Direct Insertion of an Instrument to PA System
One of the most popular uses of a DI box is getting the signal of the bass guitar to the PA system. Simply put, the low frequencies produced by bass are difficult to mic/record, so use of a DI box is almost always preferable.
Have the capability of tapping off signals from amplifiers, such as the output or guitar amp or power amplifier. You can even connect this unit to the line output of a consumer stereo system or boom box --if you want to sample some old records or cassette tapes.
This DI box also does a great job in the studio for connecting unbalanced devices. For instance, the output levels of many keyboards are low, so their signals can benefit generally by connecting their unbalanced outputs to the unit which makes the signal to move cleanly without interruption. The signal will be allowed to travel for long distances while benefiting from the low noise and common mode rejection provided by this unit's balanced low-level output.
