Speaker Types
The XDC-1 consists of two types of speakers.
•Main speaker (Model XD1) x 2 •Subwoofer (Model XDSW1) x 1
The cabinets of these speakers are made from natural wood so the grain
finish differs from that of artificial wood. The appearance of each cabinet
will differ slightly and has its own individual character. As molded plywood
has been used, the surfaces may have a slight roughness but this does not
have any influence upon the performance.
Standard Arrangement
The sound image becomes sharper the closer the subwoofer is placed to the main speakers.

Precautions for Use
To maintain the look of the unit
Wipe with a dry, soft cloth if the cabinet or control panel should become dirty.
If very dirty, apply a small amount of water or neutral detergent to the cloth and
Wipe clean. Then wipe with a dry cloth.
Good manners when listening to system
When you are listening to the system, please listen at volume that will
not disturb your neighbors. At night, in particular, even soft sounds
spread easily to your surroundings. Please show consideration and
close windows, or listen using headphones, etc. in order to maintain a
pleasant living environment.
The symbol shown here is the Sound Etiquette symbol mark.
Improving the sound field
If the speakers are facing a solid wall or glass door, etc., it is
recommended to furnish the wall with materials that absorb sound,
for example by hanging up heavy curtains, to prevent generation of
reflections and standing waves.

Precautions for Installation
•To prevent deformation or discoloration of the cabinet, do not install
the unit where it is exposed to direct sunlight or high humidity, and
avoid installation near air conditioning outlets.
•Speaker vibrations may cause playback devices to malfunction or
skip. Place the unit as far away from the playback device as possible.
•Take the occurrence of earthquakes or other physical shocks into
consideration when selecting the installation place, and secure the
unit thoroughly.
•This unit is magnetically shielded so as not to cause color distortions on color television sets. However, depending on the
installation method, color distortions may occur. Please pay attention to the following points when installing the unit.
1. When placing these speakers near a TV set, turn off the TV’s main power switch or unplug it before installing the speakers.
Wait at least 30 minutes after the system is installed before turning on the TV’s power.
2. If another speaker system has been set up near the TV set, that system may cause color distortions in the TV’s picture.
In spite of the shielded design of these speakers, some types of TVs may be affected by them. If this happens, move the speakers
a short distance from the TV set.
•When placing the speaker system, note that the affixed feet on both
the satellite speakers and subwoofer (as well as the optional taller
feet) may slightly discolor the setting surface after an extended
period, depending on the setting surface’s material.
•To be considered when installing the XDC-1
•The sound reproduced by the speaker system is subtly affected by
the conditions of the listening room. The arrangement of this
system can be changed to match the conditions of the listening
room. We recommend that you use the following guidelines to
arrange the system to expand the sound field and ensure a clearly
pinpointed sound image.
•XD1 (Main Speaker)
•We recommend that there be at least about 20 in. of free space
between the sides and a wall.
•We recommend that there be at least about 4 in. of free space
between the rear side and a wall.
(Note that there is a risk that terminals may be short circuited if they
contact a wall, etc.)
We recommend that there be a distance of about 3 to 7 feet between
each speaker, and each speaker should be placed with the front
facing forward towards the listening position.

Connections
■Before connecting
1. Turn OFF the subwoofer before the connecting the main speakers to it. The amplifier for the main speakers may be
damaged if the speaker cables are short-circuited while the subwoofer is on.
2. The maximum input accepted by the system is 50 watts. This is the value (rms) at which the signal source can be input
for a short interval without the speaker suffering damage.
■Normal connections
1. Connect the XD1 to the XDSW1 as shown in the figure 1below.
2. Connect the output of your source to the input of the XDSW1 as shown in figure 2below.

Connections (continued):
•The XDC-1 accepts low-level stereo signal sources, such as home or portable CD/DVD players,
mp3 players, computer soundcards, gaming consoles, etc. It will also accept the tape or preamp
output from a receiver or preamp (we suggest the preamp output as it allows for volume control).
•Some sources (such as computer soundcards and portable mp3/CD players) only output through
3.5mm connectors; for these applications, use of a 3.5mm/2 RCA Cable (included), or a 3.5mm/2
RCA Adapter (available through Xhifi) is required.
•The XDC-1 employs two different volume controls, one for the subwoofer only, and one “master”
for the entire system (consisting of both speakers PLUS subwoofer). If the signal source also
employs a volume control, please consider using this when operating the system (see below).
•Utilizing a crossover fixed at 230 Hz, the subwoofer divides the incoming signal into two parts,
retains the bass portion, then sends the midrange/treble portion to the main speakers. The
XDSW1 subwoofer can be used as a stand-alone subwoofer, but please note that the speaker
output terminals on the XDSW1 will remain active (for connection to the XD1 Satellite Speaker
ONLY).
•Make all connections before the plugging the AC power cord into an AC Outlet.
Operation
•STANDBY/ON lamp (with auto power on/off function) – applicable to XDSW1 Subwoofer ONLY
When the POWER button is pressed to ON, the STANDBY/ON lamp lights up green. If about 30 minutes elapse with no signals, the mode
switches to the standby mode, and the STANDBY/ON lamp lights red.
When audio signals are input, the mode automatically becomes the ON mode, and the STANDBY/ON lamp lights green.
ON mode: STANDBY/ON lamp lights green.
Standby mode: STANDBY/ON lamp lights red.

Operation (continued):
We recommend using a music source for setup.
Before pressing “Play” on your source, make sure the XDSW1’s MASTER
VOLUME and SUBWOOFER VOLUME controls are turned all the way down. If
your source also has a volume control, make sure it is turned all the way down.
Adjusting the volume
After pressing “Play” on your source:
1. Turn up your source/preamp/receiver’s volume control (if applicable) to 75% of its
maximum.
2. Turn up the XDSW1’s MASTER VOLUME control until it reaches the 6:00 position.
3. Slowly turn up the XDSW1’s SUBWOOFER VOLUME control, until you reach a
preferred bass level and blend with the main speakers.
4. Once you have achieved your preferred bass blend, if your source also has a volume
control, we recommend using that to control the volume of both the main speakers and
subwoofer at once. If your source does not have a volume control. you can also use the
unit’s MASTER VOLUME control for this purpose, noting the following conditions:
(1) At its minimum position, the MASTER VOLUME control will not fully mute the
satellites or subwoofer. To mute both at once, you must either turn the source’s
volume all the way down (if possible), or stop/pause its playback.
(2) The MASTER VOLUME control raises and lowers the satellites and subwoofer at
different rates; therefore, you may need to adjust the SUBWOOFER VOLUME
control to compensate for any change in the MASTER VOLUME.
The XDSW1 subwoofer has a protection circuit which automatically reduces the output of
the subwoofer when the source’s volume exceeds the allowable input of the subwoofer
circuit. In this event, lower the volume of your source (if possible) to a level at which the
protective circuit does not activate. NOTE: This circuit only engages under extreme
circumstances, and will not do so when presented with typical fixed or variable output
(with volume control) sources like computer soundcards, mp3 players, gaming consoles,
CD/DVD players, etc.
