This symbol indicates an advisory warning
Once connected to the mains supply, never attempt to remove drive units or rear amplifier panels. Do not use these
loudspeakers if defective and if for any reason they are found to be defective, unplug from the mains supply.
Only use the supplied power cables and USB power adapter and replace immediately if damaged.
Should you have any problems please contact your Blue Aura Distributor.
The loudspeakers are covered with a soft faux leather material. Please take care when unpacking the speakers to
avoid scratching or indenting the material.
Before installing this product please read all of the instructions.
The amplifier inside the loudspeaker have built in thermal and short circuit protection.If an amplifier is driven beyond
its power output capabilities it will produce distorted sound which may damage your loudspeakers. Make sure
you do not leave your loudspeakers unattended when playing and reduce the volume at the first sign of audible
distortion.We recommend that you keep all packing until you are completely satisfied with your purchase.
The mesh grilles on your WS90t loudspeakers have been designed to provide acoustic clarity and no significant
sound improvement will be gained by removing them.

loudspeaker is stable.
Adjust spikes where necessary to ensure
loudspeaker is level, and then fully tighten
lock nuts.
Spike support cups are available to use
where Spikes are preferred but flooring is
to be protected.
Why use spikes?
Some low frequency energy is dissipated when a loudspeaker
is placed on a soft surface, i.e. carpets. This effect can be
minimised by using Spikes to help couple the loudspeaker to the
Spikes help to minimize overall vibration of the loudspeaker by
reducing the amount of sound energy between the loudspeaker
and the floor
Loudspeaker placement
Left and Right loudspeakers can be identified by looking at the amplifier panel on the rear of each cabinet. Place the
loudspeakers in your preferred position but within reach of wall sockets. With the wall socket in the OFF position connect the
power lead to the loudspeaker using only the supplied power cables. Once connected, the mains switch can be turned to
the ON position.
What is the ideal position for my WS90t loudspeakers?
Placing each WS90t at least 300mm from the back wall will reduce reflections and improve accuracy and detail. Each
loudspeaker should be the same distance from where you are seated. Ideally the loudspeakers and the listening position
should form an equilateral triangle. Depending on room layout, some “toeing in” may improve stereo imagery and staging
by reducing reflections from side walls.
