The PDC21 can be quite useful on stage or in the studio for connecting unbalanced devices, particularly key boards. The output levels of many keyboards are low. So their signals can benefit greatly by connecting their unbalanced outputs to the PDC21 by doing so the signal can be sent cleanly for long distances while benefiting from the low noise and common mode rejection provided by PDC21’s balanced low-level output. The diagram following shows a typical hook-up for a stereo keyboard connected to a stereo stage monitor system and the main PA mixer.
