Getting Started Operations TroubleshootingENGLISHConnections and SettingsNOTE• Do not plug in the power cord until all connections have been completed.• When making connections, also refer to the operating instructions of the other components.• Be sure to connect the left and right channels properly (left with left, right with right).• Do not bundle power cords together with connection cables. Doing so can result in humming or noise.Connections for all compatible audio signal formats are described in these operating instructions.Please select the types of connections suited for the equipment you are connecting.With some types of connections, certain settings must be made on the POA-A1HD. For details, referto the instructions for the respective connection items below.Audio cables Signal directionAnalog connections (XLR)Balanced cableAnalog connections (RCA)Pin-plug cableSpeaker connectionsSpeaker cablesAudio signal:OutputInputInputOutputCables Used for ConnectionsSelect the cables according to the equipment being connected.PreparationsCarefully check the left (L) and right (R) channels and + (red) and – (black) polarities on the speakers beingconnected to the POA-A1HD, and be sure to interconnect the channels and polarities correctly.1 Peel off about 10 mm of sheathing from the tip of the speaker cable,then either twist the core wire tightly or terminate it.2 Turn the speaker terminal counterclockwise to loosen it.3 Insert the speaker cable’s core wire to the hilt into the speakerterminal.4 Turn the speaker terminal clockwise to tighten it.NOTE• Connect the speaker cables in such a way that they do not stick out of the speaker terminals. Theprotection circuit may be activated if the core wires touch the rear panel or if the + and – sides touch eachother (vProtection circuit).• Never touch the speaker terminals while the power supply is connected. Doing so could result in electricshock.Protection circuitIf speakers with an impedance lower than specified are used for an extended period of time with thevolume turned up high, the temperature may rise, activating the protection circuit.When the protection circuit is activated, the speaker output is shut off and the power indicator flashesred. If this happens, unplug the power cord, then check the speaker cable and input cable connections.If the set is extremely hot, wait for it to cool off and improve ventilation around it. Once this is done, plugthe power cord back in and turn the set's power back on.If the protection circuit is activated again even though there are no problems in the ventilation around theset nor in the connections, the set may be damaged. Turn the power off, then contact a DENON servicecenter.Connecting the speaker cablesConnections and Settings1.POA-A1HDE2_ENG.indd 9 2008/01/18 11:34:28
