Connecting the Speaker Cables
Carefully check the left (L) and right (R) channels
and + (red) and – (black) polarities on the speakers
being connected to the AVR-488, 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
Tighten the speaker terminal firmly before
inserting the banana plug.
NOTE
• Use speakers with an impedance of 6 to 16
Ω/ohms. When using front A and B speakers
simultaneously, use speakers with an impedance
of 12 to 16 Ω/ohms.
• 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) are used for an
extended period of time with the volume 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
flashes red. 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, 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.
