• Do not operate near heaters or place it near other apparatus
which produce a lot of heat.

• Only use accessories specified by the manufacturer.

• Make sure the mounting surface can easily support the
speaker’s weight.

• Use only industry-accepted mounting tools and methods.

• Exposure to loud audio levels over a long time can cause severe
hearing loss.

• Don’t forget to consult the local law directions regarding
producing sound in public places.

The enduring success story

The origin of MASK loudspeakers goes back as far as 2006, when
the introduction of MASK4 and MASK6 set an industry standard for
numerous professional users all over the world. Reliability, sound
performance, an unseen design and a unique ease-of-use Intelli­mount bracket resulted in an instant success in every major market
worldwide.

So with this essential philosophy of construction quality, reliability,
ease-of-installation and sound performance in mind the next
generation of MASK was created.

MASK4C - MASK4CT / MASK6C - MASK6CT

A designer evolution with an installer friendly revolution. MASKC
series got a subtle facelift resulting in a more mature look and feel.
Its underlying engineering evolved to an unprecedented level,
exceeding every installer’s expectations.

The patent pending ClickMount bracket is a true revolution for
installers and users alike.

Rigid constructed to withstand the most fierce conditions in which
a professional loudspeaker can be used. MASK will remain an iconic
industry standard for many years to come.

• Determine the position where the ClickMount will be mounted
on the wall. Please allow a minimum distance of 105 mm for
MASK6C and 50 mm for MASK4C between the top of the
ClickMount and the ceiling is necessary when installing the
speaker in the upright position. The cable entry point is 95mm
below the top of the bracket. The cable can enter from the
rear of the bracket so that it is completely hidden from view.
The ClickMount MUST be mounted with the arrows facing
upwards!

• Now mark the four mounting holes on the wall. Use the built-in
spirit level for correct positioning of the ClickMount unit.

Drill the mounting holes and attach the ClickMount in place using
adequate hardware. Use only hardware capable of supporting the
speaker’s weight safely. Be careful when you drill the holes in the
wall: make sure not to drill into the speaker cables or other objects
hidden inside the wall.

• Attach the SAFCAB cable to the rear of the speaker and
attach the other end firmly to the wall close to the ClickMount
(preferably above the ClickMount). The SAFCAB can handle
more than 10 times the speaker’s weight, so mount the
cable on the wall using appropriate mounting hardware (not
included). Do not use ClickMount to attach the SAFCAB. The
SAFCAB must be attached to the wall structure separately.

CLICK!

• The speaker can be mounted on the ClickMount in 4 ways:
upright, 90° rotated to the left, 90° rotated to the right or at
the ceiling. It is not possible nor allowed to mount the speaker
upside down on the ClickMount. When the speakers are

the logo on the grille accordingly.

MASK4C(T) / MASK6C(T)

Note: All MASK models have a unique 3 stage overload protection,
which is activated when the speakers are overloaded for long
periods. When too much power is fed into your MASK, first the
red led will blink when the music signal hits peak levels. When you
neglect this early warning, the overload protection will disconnect
the signal going to the loudspeakers and the red led will remain lit.

Turn down the music level . After about 3 seconds cooling down
the signal will be reconnected to the loudspeakers.

REMINDER

Protection systems are not built to be activated all the time, they are
to warn you and to give you a safety margin!
