Professional Power
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
high-powered speaker output from an amplifier. 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.
Clean Audio
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.
Versatile
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
speaker 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.
