Connecting the Speaker Cables Carefully check the channel numbers and + (red) and - (black) polarities on the speakers being connected to the POA-3012CI, and be sure to interconnect the channels and polarities correctly. 1 Peel off about 0.03 ft/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 speaker terminal. 4 Turn the speaker terminal clockwise to tighten it. When using a banana plug (for North America model) Tighten the speaker terminal firmly before inserting the banana plug. Protection circuit If speakers with an impedance lower than specified (for example 4 Ω/ ohms speakers / NORMAL MODE) are used for an extended period of time with the volume turned up high, the temperature may rise, activating the protection circuit. There are 2 kind of protection circuits in POA-3012CI. 1. Protection circuit for individual Amplifier (Zone 1 ~ 6) This protection circuit detects over load condition of the amplifier circuit. When the protection circuit is activiated, the speaker output of individual Amplifier (Zone 1 ~ 6) is shut off, and the Zone operation mode indicator for protected Zone No. flashes red. If this happen, unplug the power cord, then check the speaker cable and input cable connections. 2. Temperature rise protection circuit in the chassis. This protection circuit detects temperature rising in the chassis. When the protection circuit is activiated, the power source for all Amplifier circuits is shut off, and the power indicator flashes red. If this happen, it may be extremely hot in the chassis, unplug the power cord. Wait for it too cool off and improve ventilation around it. Once this is done, plug the 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 the set nor in the connections, the set may be damaged. Turn the power off, then contact a DENON service center. NOTE • Use speakers with an impedance of 4 to 16 Ω/ohms. Use a 8 to 16 Ω/ohms speaker for BRIDGED output. • Connect the speaker cables in such a way that they do not stick out of the speaker terminals. The protection circuit may be activated if the core wires touch the rear panel or if the + and - sides touch each other (v "Protection circuit"). • Never touch the speaker terminals while the power supply is connected. Doing so could result in electric shock. ENGLISH  Getting Started Connections Setup Operations Troubleshooting Specifications
