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
and even the high-powered speaker output from an amplifier. The
PDC21 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 PDC21 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 so long runs of cable are possible.
Another benefit from a balanced connection is common mode rejection.,
which provides cancellation of the bad sounds(hums and buzzes) while
leaving the original signal pure.
One of the most common applications for using a DI box is getting the
signal of a bass guitar into the PA system. Simply put, the low
frequencies produced by bass are difficult to mic, so use of a DI box is
almost always preferable. In addition, the signal going to PA system can
be tweaked by the FOH(front of house) engineer, without affecting the
sound the musician dials up on stage. You can use PDC21 to plug a
guitar directly into the PA system as well. Especially acoustic guitars with
pickups and when using electronic guitar processors and modelers.
