WARNING!
To eliminate the risk of electric shock, never open this unit. Do not subject it to
humidity or moisture of any kind. If the unit is not functioning properly, take it to a
qualified service technician.
A lightning bolt inside an equilateral triangle
warns the user that uninsulated voltage within the unit may have sufficient magni-
tude to cause electric shock.
An explanation point inside an equilateral triangle
alerts the user that important literature concerning the operation and mainte-
nance of this unit has been included.
Labeling on products that use lasers
(Does not apply to some countries)

Power source
This unit is intended for use with a 230 V AC power sup-
ply only. Connecting to a different power source may lead
to accidents or fire and can damage the unit. Check the
voltage of the power source before you connect this unit.
Power cable
This unit has a detachable power cable. Plug it into the
appropriate outlet on the back panel. Make sure that the
unit is completely turned off until all other connections
have been completed. Make sure that the power cable is
routed so that it is not pinched or in the way of foot traffic.
A damaged power cable should be replaced immediately.
Placement
Place the unit on a stable, even surface. If it is placed on
a shelf, make sure that the shelf and its brackets will be
able to bear the unit’s weight. Do not place the unit in a
humid or extremely hot or cold place or on a soft surface,
such as a rug. Make sure that the unit is well-ventilated.
We recommend at least 10 cm [four inches] of space on
all sides, as well as on top. See the figure below. In order
to insure that the unit is always properly ventilated, never
cover the ventilation holes in the cabinet.
Cleaning
Before cleaning, disconnect the power cable. The unit
can be cleaned with a soft cloth. Never use strong sol-
vents or other liquids.
Water and humidity
Do not use the unit near water (for example, a bathtub,
bathroom or kitchen sink), damp basements, wet rooms,
or a swimming pool.
Temperature
Do not use the unit in extremely high or low temperatures.
The ideal temperature is above +5º C [41º F].
Cabinet
Do not open the unit’s cabinet. There are no parts inside
the cabinet that you can repair yourself. Only an
authorized service technician can carry out repairs. Every
change in the product alters the terms of the warranty.
If a foreign object falls inside the cabinet, disconnect
the power cable immediately and contact an authorized
service center.
Abnormal odor
If the unit emits an abnormal odor or smoke, turn it off im-
mediately and disconnect the power cable. Contact your
retailer or the nearest service center.
Overloading
Do not overload wall outlets or the fuse box, as this can
result in a risk of fire or electric shock.
Connections
Use only the enclosed or recommended connection ca-
bles and accessories.
Replacement parts
When replacements are required, be sure to use parts
specified by the manufacturer or that have the same
properties as the original part. Unauthorized substitutions
may result in fire, electric shock, or other hazards.
When to contact your service representative
The unit needs to be inspected by qualified service per-
sonnel if:
- The unit has been dropped on a hard surface or been
damaged in any way.
- The unit has been exposed to rain or water.
- A foreign object has fallen inside the cabinet.

stereo plug to the PHONES output on the front panel.
When the headphones are connected, the speaker
output turns off automatically. When the headphones
are connected, there is no audio output from the speak-
ers. Adjust the volume with the volume knob. Listen-
ing through the headphones at high volumes can be
dangerous to one’s hearing.
NOTE! Before disconnecting headphones, turn the vol-
ume knob to minimum (VOL OO).
Connecting an audio source to LINE IN on the front
panel
Connect an external sound source (such as an Mp3
player) to LINE IN on the front panel. Use a cable with a
3.5 mm [1/8 inch] stereo plug. Select LINE as an audio
source using the SOURCE button on the front panel or
the INPUT button on the remote control.
Connecting an audio source to AUX on back panel
Connect an external audio source (such as a CD player,
DVD player or computer) to the AUX inputs on the back
panel. Use a cable with PHONO plugs. Select AUX 1,
2 or 3 as the audio source using the SOURCE button
on the front panel or the INPUT button on the remote
control.

STEREO ONE ACE PLUS SPEAKERS
Stereo Two ACE PLUS speakers
These speakers are included in the packaging. They were designed and developed to be used exclusively with the
Stereo Two CD receiver. These speakers can not be connected to another amplifier. The enclosed speaker cables
can be replaced by another cable if other length is required.
Thanks to Audio Pro’s patented ACE BASS technology, Stereo Two ACE PLUS, together with the Stereo Two CD
receiver, offers a unique audio experience.
What is ACE BASS?
The laws of physics apply to the construction of ordinary speakers. As a consequence, in order for it to reproduce a
deep bass, the speaker cabinet would have to be very big. With our ace bass technology, we can “alter” the laws of
physics to make the speaker element believe that it is housed in a much bigger speaker cabinet than it is really is. In
addition, this technology also makes it possible for us to improve the unit’s electronic performance and properties.
Connecting the speakers
Read more about connecting the speakers on page
10. Be careful to connect the red cable to + and the
black cable to -. Use only the included cables. They
must not be shortened or lengthened.
Note that the cables are different. The end with the
crimped fork terminals must be connected to the
speakers.
Placement
The Stereo Two ACE PLUS is designed to be placed
on a stand, table, or bookshelf. If the speaker is
placed on a bookshelf, make sure that there is at
least 10 cm [4 inches] of space in back of it.
Try to place the speaker in accordance with the
figure below. For an optimal stereo image, axis (y)
should be shorter than axis (x). For a wider stereo
image, the speakers can be turned inward slightly.
