PDC21 1/4'' Instrument To Balanced & Unbalanced (1/4''/XLR) Direct Box
Front and Rear Panel Layout 1 5 2 3 4 1. INPUT: 1/4" input connector. 2. PARA OUT: It’s parallel output 1/4" jack for passing the input signal through to a stage amplifier or monitor system. 3. ATT Switch: input attenuation, switchable(0dB,-20dB,-40dB) 4. BALANCED OUTPUT: Male XLR connector. 5. GROUND: When engaged, the ground from the PDC21 chassis detaches from the XLR jack.
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. Direct insertion of an Instrument into a PAsystem One of the most common applications for using a DI box is getting the signal of a bass guitar into the PA system.
Connecting to High Power Signals The PDC21 provides the capability of tapping off the signals from amplifiers, such as the output or guitar amp or power amplifier. You can even use PDC21 o connect to the speaker output of a consumer stereo system or boom box, for example, if you want to sample some old records or cassette tapes. NOTE: Be sure that the ATT switch is set to (-20db or -40db) position before connecting the signal from the output of any amplifier.

The output levels of many keyboards are low.
