Connecting the PPA-1 to Your Audio System
First, turn your power amp off. Do not connect the PPA-1's power supply until all audio connections have been made.
Power Supply Connection: Stock Power Supply
To connect the stock AC power supply that comes with the PPA-1, connect
the power supply's cable to the coaxial AC power input on the upper right
corner of the back of the PPA-1. Do not plug the power supply into the AC
wall socket until you have finished all audio connections. Do not connect
the stock power supply if you are using the PS-5 Power Station.
If you are using the optional PS-5 Power Station pow-
er supply, plug the cable that comes with the power
supply into one of the multipin DC outputs on the
back of the PS-5, then into the multipin Power Station
input near the lower right corner of the PPA-1. Do not
plug the PS-5 into the AC wall socket until you have
finished making all audio connections. Be sure to dis-
connect the stock AC power supply before you con-
nect the PS-5 Power Station.
