4. rds 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 Specifications Frequency Response 5 35 KHz 3dB Noise Level 22 22KHz Input Shorted 104dBu THD N 10Hz 22KHz 0 013 typ 1 VRMS 1KHz Input Impedance 50K Ohm Max Input Level 1 THD 8 1 dBu 9V Batt 11 3dBu 48V Phantom Instrument Input 1 4 Phone Jack unbalanced Parallel link out 1 4 Phone Jack unbalanced BALANCED OUTPUT XLR Connector balanced Dimensions 4 72 x2 95 x1 57
