THE PLACEMENT AND INSTALLATION OF LOUDSPEAKER
The size of the room, the treatment of the wall and floor surfaces, the
placement location of the loudspeakers in the room are all factors to
achieve optimal sound reproduction. Please carefully read the following
references：
position of furniture and the
zIt is recommended the loudspeakers and the listener to be in the
direction of long axis. Please see the fig.1. If the loudspeakers and
listener are located in the direction of short axis, the sound quality
will not be as refined due to wall reflections. If you have no choice
to set up this way, you may need to do some sound absorbing
treatment on the front and back walls. The shape and size of the
room have a great influence in the outcome. You should experiment
with positioning a number of times to find the SWEET SPOT.
zThe optimum height for the loudspeakers placed on the floor, the
center of the aluminum ribbon tweeter should be on the same level
with your ear when you sit on your accustomed seat.
Please see the fig.2.
zDo not place the loudspeakers near walls or corners. fig. 1
Usually, the distance between the back of
the loudspeaker and the wall is a minimum
of 1m/40"; the distance from the side of
the loudspeaker to the nearest wall is a
minimum of 0.8m/32". Of course, the
optimum position will depend on room
size and layout. Please assure that the
optimum position can be found as long
as you move the loudspeaker several times.
zIf you position the loudspeakers too close to
the wall or corners, it will increase the bass response
and at the same time becomes cloudy and will loose imaging.
zIf the wall and floor surface is too smooth, it will increase sound reflections and lengthen the
reverberation time and hence makes the sound muddy. If you meet these circumstances, you must
do some partial treatment to the wall and floor. Sound quality will improve if you install a wall
hanging and place a rug in front of the loudspeakers on the floor.
zThe loudspeaker should be located on a flat stable floor; spikes must be installed and adjusted to
suit.
CONNECTING LOUDSPEAKERS TO YOUR POWER AMPLIFIER
It is very simple to connect the loudspeakers to the amplifier, but the cable that connects the
loudspeakers with the amplifier can have a significant effect on the overall sound quality of your
audio system. So please choose high quality loudspeaker cables that can match your audio equipment
perfectly, ask your AURUM CANTUS dealer or distributor for their recommendation.
2

630 loudspeakers have four connectors (for bi-wiring use) on the rear panel. And each connector can
accept spade plugs, banana plugs or bares wire.
Make sure the output terminals “+”or“red”on the amplifier are connected to the connectors “+”
or“red”on the loudspeakers, likewise, make sure the output terminals“－”or“black”on the amplifier
are connected to the connectors“－”or“black”on the loudspeakers, and then please double check the
connections are correct and stable.
When using the bi-wring system, firstly remove the gold short-circuit plates from the connectors, and
then connect the cables following the above instructions.
NOTE：
BEFORE POWER UP, YOU MUST REMOVE THE PROTECTIVE MEMBRANE FROM
THE ALUMINUM RIBBON TWEETER.
THE OPERATION APPROACHES POWER UP
zFirstly, switch on the power of the sound source equipment (CD, SACD, DVD－Audio, LP, DVD
ect) , then switch on the power source of the amplifier (you must assure that the volume control of
the amplifier is set in the lowest (0) position)，lastly raise the output power of the amplifier slowly
after you inserted the software into the sound source equipment until you are satisfied with the
volume.
When you want to shut down the audio system, please firstly dial the volume to the lowest (0)
position, and then switch off the power source of the amplifier, lastly switch off the power of the
sound source equipment.
zPlease adjust the volume with care when you are playing dynamic music. If the sound pressure
level is too strong, the instant peak value of the dynamic music may cause the amplifier to distort
and can cause damage to the loudspeakers.
zIf you purchased a low-priced amplifier, please use it with care.
LOUDSPEAKERS BREAK IN PERIOD
After testing, the aluminum ribbon loudspeaker requires at least 80 hours of break in to obtain the
normal working condition. In order to achieve the optimum performance sooner, we recommend the
loudspeakers break in as continuously as possible.
CLEANING YOUR LOUDSPEAKERS
zPlease do remember not to use a vacuum cleaner on or near the loudspeakers, otherwise it could
cause damage to the diaphragm of the aluminum ribbon tweeter.
zPlease remove the grille before cleaning the grille cloth.
zUse a damp soft cloth to clean the cabinets. We recommend maintaining an occasional furniture
grade wax and polish the wood surface of the cabinet.
ATTENTION
zThe magnetic field of the aluminum ribbon tweeter is very powerful, so please keep any
magnetizer away from the front plate of the loudspeaker at least 20cm/8"to avoid loudspeaker
damage due to the strong magnetic attraction.
zPlacing the loudspeaker near a television may cause a magnetic interference. Place the speaker
about 90cm/35"away from your television when you combine your loudspeakers with a home
theater system.
zLoudspeakers should be placed away from heat sources and prevent direct sunlight on the
loudspeakers, otherwise, this can cause life reduction of the drivers and aging of the cabinet finish.
zMake sure that you have read and understand the information in this manual. If there is anything
you don’t understand or are unsure of, please contact your AURUM CANTUS dealer or distributor.

zNow you have responsibility to set up your loudspeakers following the recommendations set out
