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.
1Peel 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.
2Turn the speaker terminal
counterclockwise to loosen it.
3Insert the speaker cable’s core wire to
the hilt into the speaker terminal.
4Turn 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.
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.
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.
