Introduction
Thank you for buying the Apart MASK12 speaker. With this new
member of the MASK series, we have once again broken new
ground in sonic performance and installer convenience. The
MASK12 speaker is meant for fixed indoor installations. Available
in 8 ohms and 100 volt, MASK12 can be used in many full range
applications where a medium to high sound pressure level is
required.
The multi-angle plywood cabinet, equipped with 14 rigging points
for shoulder eye bolts, and the optional wall/ceiling U-bracket allow
you to safely install the speaker in many different positions, be it in
a horizontal or vertical position, close to the ceiling or at the wall.
With a weight of only 19.2 kgs, the speaker is easy to install.
As usual, these Apart speakers will convince you in terms of sound
quality, reliability and setup versatility. Paired with our Revamp
2600 amplifier, your sound system will be taken to a new level of
performance.
Please read this manual carefully before using the product. This
will give you the necessary product and installation instructions to
assure a seamless installation and non-compromised overall sound
quality.

Speaker installation
Install the speaker on the wall or ceiling using our optional
U-bracket. Make sure the wall, ceiling, surface, structure and
additional mounting hardware are capable of safely supporting the
speaker’s weight. When suspending the speaker with chains, make
sure to mount the M10 shoulder eye bolts (not supplied) on more
than one side of the speaker. Use at least 3 chains, for example,
one at the top of the speaker, and 2 on each side. Adjust the length
of the chain(s) to position the speaker correctly. Do not attempt to
suspend multiple speakers on the same set of chains or brackets.
For safety reasons, every speaker must be mounted using its own
set of chains or brackets.

Speaker orientation
The high frequency horn has a nominal dispersion angle of 90°H
x 70°V. When the speaker is mounted horizontally, we advise to
rotate the high frequency horn by 90° to ensure the 90° horizontal
dispersion angle. The Apart logo on the grille can also be rotated.
In order to mount the speaker close to the ceiling, one side of the
speaker is angled.
