Features
Advanced HC (High-Current) single push-pull
circuit installed to simultaneously achieve both
“subtlety” and “powerfulness”
Employs HC transistors that pass 2 – 3 times the peak current
of conventional audio power transistors, to acquire a stable,
expressive quality of music from extremely low-levels to high
volume.
High-speed, large current capacity power circuit
To draw out the full potential of the HC single push-pull circuit,
the power circuit uses DENON custom-specification block type
electrolytic capacitors, as well as SBD (Schottky-Barrier Diode)
with short reverse recovery time and minimal current noise.
Source Direct function, for pure audio playback
Achieves pure audio playback, protecting the purity of the sound
by by-passing TONE (BASS, TREBLE), LOUDNESS and BALANCE
controls.
Reduced power consumption during standby
In consideration of the environment, power consumption during
standby has been reduced to 0.3 W or better.
Cautions on handling
•Before turning the power on
Check once again that all connections are correct and that there are
no problems with the connection cables.
•Power is supplied to some of the circuitry even when the unit is
set to the standby mode. When going on vacation or leaving home
for long periods of time, be sure to unplug the power cord from the
power outlet.
•About condensation
If there is a major difference in temperature between the inside of
the unit and the surroundings, condensation (dew) may form on
the operating parts inside the unit, causing the unit not to operate
properly.
If this happens, let the unit sit for an hour or two with the power
turned off and wait until there is little difference in temperature
before using the unit.
•Cautions on using mobile phones
Using a mobile phone near this unit may result in noise. If that
occurs, move the mobile phone away from this unit when it is in use.
•Moving the unit
Turn off the power and unplug the power cord from the power
outlet. Next, disconnect the connection cables to other system units
before moving the unit.
•About care
•Wipe the cabinet and control panel clean with a soft cloth.
•Follow the instructions when using a chemical cleaner.
•Benzene, paint thinner or other organic solvents as well as
insecticide may cause material changes and discoloration if brought
into contact with the unit, and should therefore not be used.

v See overleaf
Connections for all compatible audio signal format is described in
this operating instructions. Please select the types of connections
corresponding to the equipment you are connecting.
NOTE
•Do not plug in the power cord until all connections have been
completed.
•When making connections, also refer to the operating instructions of
the other components.
•Be sure to connect the left and right channels properly (left with left,
right with right).
•Do not bundle power cords with connection cables. Doing so can
result in humming or noise.
•Do not turn up the volume without a turntable connected to the
PHONO input terminals. Doing so will cause humming or noise.
n Cautions on playing SA sources:
When regular speakers not compatible with SA sources (DVD
Audio discs, Super Audio CDs and other sources, including
treble components above the audible range), set the properties
of the player (DVD Audio player, Super Audio CD player, etc.)
for use with regular speakers (or amplifiers).
The speakers may be damaged if the volume is set too high
when playing SA sources. For instructions on player settings,
refer to the operating instructions included with the player.
Cables used for connections

Connecting the speakers
Connecting the speakers cables
Carefully check the left (L) and right (R) channels and + (red) and –
(black) polarities on the speakers being connected to the unit, and be
sure to connect the channels and polarities correctly.
Peel off about 10 mm of sheathing

from the tip of the speaker cable, then
either twist the core wire tightly or
apply solder to it.
Turn the speaker terminal

counterclockwise to loosen it.
Insert the speaker cable’s core wire to

all the way into the speaker terminal.
Turn the speaker terminal clockwise

to tighten it.
NOTE
•Connect the speaker cables so they do not stick out of the speaker
terminals. The protection circuit may be activated if the wires touch
the rear panel or if the + and – sides touch each other (vpage5
“Protection circuit”).
•Never touch the speaker terminals while the power supply is
connected. Doing so could result in electric shock.

Protection circuit
The protection circuit is be activated in the following situations:
•If the speaker cable wire touches the rear panel or screws or if the speaker cable wire touches the
speaker cable’s + and – sides are touching
•If the surrounding temperature is extremely high
•If the inside of the amplifier gets hot to extended use at a high output
If this happens, unplug the power cord, then check the connections of the speaker cables and input cables.
If the unit becomes very hot, wait for it to cool off and improve the ventilation around it. After doing this,
plug the power cord back in.
If the protection circuit is activated even though there are no problems with the ventilation around the unit
or in connections, the unit may be damaged. Turn off the power and then contact a DENON service center.
Speaker A/B connection (PMA-720AE only)
•The same signal is output from the SPEAKER A and B terminals.
•When only one set of speakers is to be connected, use either the SPEAKER A or B terminals.
