User Manual

A direct box, or DI box, provides the facility for the direct insertion of an audio
signal into a mixer or recorder. The PDC22 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 PDC22 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 PDC22 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 PDC22
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. Follow the diagram and steps below to connect a guitar to a PA
mixer.
