Making Audio Connections
Audio input connections are made using the included green 3-pin terminal-block connectors (HARMAN
part number: 32-0381)� Audio output connections are made using the included orange 3-pin terminal-block
connectors (HARMAN part number: 5089098-00)�
Audio Input and Output Wiring Convention
The DCP-555 provides cable shielding "back from the destination" to eliminate ground loop problems� This
means that the shield connection on an input is grounded, whereas the shield connection on an output is
floating (although connected via an internal network to ground for EMC compliance)�
