• This unit is equipped with a high-speed protection circuit. The purpose of this circuit is to protect the speakers under circumstances such as
when the output of the power amplifier is inadvertently short-circuited and a large current flows, when the temperature surrounding the unit
becomes unusually high, or when the unit is used at high output over a long period which results in an extreme temperature rise.
When the protection circuit is activated, the speaker output is cut off and the power supply indicator LED flashes. Should this occur, please
follow these steps: be sure to switch off the power of this unit, check whether there are any faults with the wiring of the speaker cables or
input cables, and wait for the unit to cool down if it is very hot. Improve the ventilation condition around the unit and switch the power back
on.
If the protection circuit is activated again even though there are no problems with the wiring or the ventilation around the unit, switch off
the power and contact a DENON service center.
Protector circuit
• The protector circuit may be activated if the set is played for long periods of time at high volumes when speakers with an impedance lower
than the specified impedance (for example speakers with an impedance of lower than 4 Ω/ohms) are connected. If the protector circuit is
activated, the speaker output is cut off. Turn off the set’s power, wait for the set to cool down, improve the ventilation around the set, then
turn the power back on.
Note on speaker impedance
• With this unit’s speaker outputs, signals with the reverse phase of the “+” side output terminal’s signals are also output from the “-” side
output terminal.
Do not connect to a device for switching between multiple speakers (a speaker selector or audio channel selector) or connect in ways other
than described in this manual. Doing so will result in damage.
Cautions on connecting
(7) Speaker system connections
Be sure to turn the amplifier’s power off when connecting the
speaker systems.
• Use the included cables to connect the input terminals on the back
of the speaker systems (see diagram) to the amplifier’s speaker
output terminals. Connect the speaker system for the left channel
amplifier’s “L” terminals, the one for the right channel to the
amplifier’s “R” terminals, matching the polarities (“≈” and “√”
marks). Inverting the polarities will result in unnatural sound, with
the phase off or no low bass sound. Also check that all two terminal
knobs are tightly fastened.
Connections
(The red terminals on the right side are the “≈” terminals, the black
ones on the left side the “√” terminals.)
Loosen the terminals knobs, insert the cables’
core wires, then tighten the knobs.
Connect to amplifier’s “≈” side. (Copper color)
Connect to amplifier’s
“√” side. (Silver color)
NOTE:
Make sure the core wires do not touch
each other.
Connecting the speaker cords
Use the included connection cords to connect the input terminals on
the backs of the speaker systems (see the diagram at the right) to the
ADV-M71’s speaker output terminals.
• Connect the speaker system for the left channel to the “L”
terminals, the speaker system for the right channel to the “R”
terminals, and be sure the polarities (“+” and “–”) are properly
interconnected.
• Note that if the polarities are inverted, the phase may be off and the
bass sound may be missing, resulting in an unnatural sound. Also
check that both the speaker terminal’s screws are tightly screwed.
Either twist the core wires
firmly or terminate the wires.
