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-788, 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.
