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.

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.

Turn the speaker terminal

counterclockwise to loosen it.

Insert the speaker cable’s core wire to

the hilt into the speaker terminal.

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.

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 Ampilﬁer (Zone1 ~ 6)

This protection circuit detects over load condition of the ampliﬁer

circuit.

When the protection circuit is activiated, the speaker output of

individual Ampliﬁer (Zone1 ~ 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.
