CAUTION: Do not attempt to use MASK2
units as full range loudspeakers. They are not
designed to reproduce bass frequencies and do not
have overload protections. Biamp recommends using
matching subwoofers (SUBLIME) and/or high-pass
filter systems. Contact Support for the recommended
components to use with MASK2 loudspeakers.

MOUNTING THE SPEAKER
1. Point the center of the speaker at
the center of the listening area.
2. Test t the speaker on the
bracket to ensure the desired
angle (see Step 7) before
mounting the bracket on the
wall.
3. Using the bracket as a
template, drill the mounting
holes as shown in Figure 1.
Note: The base plate may be rotated by 45 or 90
degrees to get the maximum tilt angle in the desired
direction when installing in a corner.
4. If the speaker location is pre-wired, thread the wiring
through one of the four pre-cut cable entries on the
bracket base prior to mounting the bracket (Figure 2).
5. Mount the bracket to the surface (Figure 3). The
mounting materials for solid brick walls are included.
6. Tighten all the screws and cover with the screw
covers (Figure 4).
7. Determine the angle of the speaker by adjusting
the bracket base and the H-hook on the half-sphere
ball. The H-hook can be adjusted with or without the
speaker attached to the hook. Adjust the turning force
of the H-hook by tightening or loosening the central
screw (Figure 5).
8. Slide the rubber security piece (a) out from the back
of the speaker and slide the speaker on to the H-hook
(b) on the mounting bracket. Slide the rubber piece
back in place to lock and secure the cabinet
(Figure 6).
9. Remove the euroblock connector (a) from the
speaker and connect the speaker wires (b)
maintaining the polarity marked on the back of the
speaker: + is positive, - is negative (Figure 7).
Fully insert the bare portion of each wire into the
connector. Maintain the same color code for all of the
sound system wiring from amplier to loudspeakers.
Note: For distances up to 20 meters, 0.75 mm²
(18AWG) speaker wire can be used without loss of
performance. For longer distances use thicker wire.

CAUTION: Do not attempt to use MASK2 units as
full-range loudspeakers. They are not designed to

CAUTION: The overload protection system is
incorporated in subwoofers and amplifiers, NOT in
the MASK2 speaker.

PAINTING THE LOUDSPEAKER
CAUTION: Although the loudspeaker is paintable,
the MASK2 grille is not removable and should not be
painted.
1. Fully mask the grille and loudspeaker face so that
all internal components will not receive any paint.
Also mask o󰀨 any input, mounting connections, and
safety labels. Don't use conventional masking tape
and NEVER use duct tape. These kinds of tape leave
adhesive residue that is di󰀩cult to remove and may
cause damage. Painter's or other low-adhesive tape
is best.
2. Spray paint with two light coats. Let all components
dry completely before reassembly.
3. Remove all of the masking materials.
CAUTION: NEVER use abrasives, gasoline,
kerosene, acetone, methyl ethyl ketone (MEK),
paint thinner, harsh detergents or other chemicals on
the loudspeaker. These chemicals and agents may
permanently damage the nish. Some are also toxic
and highly ammable.
CAUTION: Blocking the grille holes with paint
or getting any paint on the drivers or internal
parts will a󰀨ect loudspeaker performance and void the
warranty.
