DS18 Candy-6 User manual

Congratulations on purchasing this DS18 CANDY-6 Class
D Full Range Amplier. The amplier has been designed
using the latest electronic technology available, allowing
you to produce high quality stereo playback in mobile
applications. This system provides you with low harmonic
distortion, a considerable amount of reserve voltage and
high temperature stability.
Just enjoy the perfect sound this amplifier brings to you!

INSTALLATION
• Since the amplier is sensitive to electrical and motor noise and
interference from the amplier may affect your radio reception, try to
mount it at least 3 feet away from the receiver. Good locations include
under a seat, in the trunk or hatch area.
• Please remember this is a high power unit which generates high
electrical energy and heat. Therefore be sure to install the unit in a place
with sufcient airow, a minimum of dust and no moisture. Allow enough
space around the cooling ns to permit reasonable airow and cooling.
It is important to ensure that the cooling ns of the heat sink are not
against a panel or a surface preventing air circulation.
• Never mount the amplier in a location that is subject to direct sunlight
or exposed to moisture. Be sure to mount the amplier to a strong, solid
surface which will not give way under the stress of a sudden stop or
accident.
• When mounting the amplier on a side wall, try to position it so that
the slots in the cooling ns are vertical. Amplier should not be mounted
on the bottom of a rear deck with the ns facing down because the heat
will radiate back up into the amplier. Leave yourself enough room on
either side of the amplier to make all the wire connections and adjust
the controls. If you have a subwoofer box in your vehicle, you can mount
the amplier on the outside of the box.
CAUTION:
If you are mounting the amplier to the vehicle’s oor, check beneath
the car to be sure your screws won’t puncture a brake or gas line.
WARNING
Continuous exposure to sound pressure levels over lOOdB
may cause permanent hearing loss. High power autosound
system may produce sound pressure levels well over
130dB, use common sense and practice safe sound please!

IMPORTANT!
Before making any connections, disconnect the cars battery until
the installation is completed to avoid possible damage to
the electrical system

POWER CONNECTION

CAUTION:
The power cables must be connected tightly. A loose connection may
cause malfunctions or interference noise or distortion.
•The +12V DC power cable should be heavy gauge stranded copper
cable with heavy insulation, since it draws power directly from the
positive battery terminal. Select the cable gauge at least 4AWG. And
the ground cable gauge should be the same as the + 12V DC.
• Connect the +12V Power terminal to the battery ( +) position terminal.
An in-line fuse must be installed in the + 12V power cable near the
battery less than 50mm. Without one, an accidental short circuit could
pose a re hazard and damage your amplier. Connect the fuse holder
to battery, however, do not install fuse at this time.
• Connect the GROUND Power terminal directly to the battery ( -)
position terminal or the car chassis. Ensure that all paint or other
insulation is remove from around the hole area, and using self tapping
screw, securely afx the bare wire ends to the vehicle chassis. Use as
short as possible.
• Many radio’ s and other music sources have an output terminal for
connection of the remote turn on of the power amplier. CONNECT the
output terminal to the amplier REM control jack. If a radio doesn’ t have
a remote turn on feature, you can connect the REM pole to external
switch for positive +12V ON/OFF.
• To help minimize interference, it is best to run the power cables along
the opposite side from the audio cables.

INPUT CONNECTIONS
• This amplier has RCA connections for low level inputs. Low level signal
is carried through RCA cables. it is preferred to use low level inputs to
the amplier if the head unit is equipped with the low level outputs.
SPEAKER OUTPUT CONNECTIONS
You do not need to make any adjustment for the input connection of
amplier before you connect the speaker output.
• Connect subwoofer wire to corresponding speaker output terminals
of the amplier.
• Be sure to have the positive wire from the speaker to the positive
speaker terminal of the amplier and the negative wire from the speaker
must connect with the speaker terminal of the amplier. Reversing any of
these connections will result in the speaker cones moving out of phase
which causes bass cancellation.
LEVEL CONTROLS
Turn the VOLUME control on the amplier to Min initially.
Once the initial power sequence has been performed, set the
CD/RADIO volume control to roughly 80% of full. Insert a CD or tune
to a radio station and slowly turn up the amplier VOLUME control until
you hear some distortion, and then back it off for clean sound.
