PRODUCT INFORMATION
Desono DX Ceiling Loudspeakers are engineered and manufactured to be rugged
and are carefully packed in sturdy cartons. However, it is wise to thoroughly
inspect each unit after it has been removed from the packaging, as damage could
occur during shipping.
All DX ceiling loudspeakers are shipped in pairs. Below is a representation
of what is included. The tile rails for the DX-IC6LP look slightly different. The
DX-IC6LP-TAA is made in the USA, contains the same elements, and is installed
the same as the DX-IC6LP.

RIGGING AND ELECTRICAL SAFETY
IMPORTANT: The loudspeakers described in this manual are
designed and intended to be mounted to diering building
surfaces using a variety of rigging hardware, means and
methods. Installation of loudspeakers should only be performed
by trained and qualied personnel. All electrical connections
must conform to applicable city, county, state, and national
(NEC) electrical codes.
. DANGER: It is possible to experience severe electrical shock
from a power amplier. Always make sure that all power
ampliers are in the "OFF" position and unplugged from an AC
Mains supply before performing electrical work.
IMPORTANT: Refer to the sections on installation and
connections later in this manual for additional information on
rigging and electrical safety.

IMPORTANT: Please review the safety guide accompanying
this product and these installation instructions prior to
installing this loudspeaker.
CAUTION: Installation of Biamp loudspeakers should only be
performed by trained and qualied personnel. It is strongly
recommended that a licensed and certied professional
structural engineer approve the mounting. Severe injury and/
or loss of life may occur if this product is improperly installed.
DANGER: It is advised that a safety cable be secured to a
suitable load-bearing point separate from the primary
loudspeaker mounting point, with as little slack as possible so
as not to develop undue kinetic force if the primary mount
were to fail.
IMPORTANT: This loudspeaker is approved for use in plenum
air handling spaces.
INSTALLATION
The DX ceiling loudspeaker family is designed to be installed with or without
above ceiling access in drop ceilings. Prewiring and installation of optional New
Construction Brackets (SPA-NCxxx) allows DX-IC loudspeakers to be installed
in new drywall ceilings. DX-IC4, DX-IC4LP, and DX-IC6 loudspeakers can be
mounted in larger cutouts using optional ceiling trim rings (SPA-TRxxx).
Once the loudspeaker is mounted, rotate the face-mounted tap switch to select
the appropriate tap setting before any audio is passed through the loudspeaker.
Do not change the setting on the tap switch while the loudspeaker is in use.
Installation in drop (suspended) ceiling (typical)
1. Run wires to the loudspeaker locations.
2. Remove the ceiling tile and use the template to cut a hole in the center of
the tile. Remove any debris from around the hole.
3. Place the tile rails on the grid and t the C-ring tabs onto the rails.
DX-IC6LP only - secure C-Ring to rails with screws (see detail below)
4. Reinstall the ceiling tile and align C-ring with the opening.

NOTE: All electrical installation
connections for loudspeaker
lines are subject to all
applicable governmental building and
re codes. The selection of appropriate
electrical hardware to interface with the
loudspeaker lies solely with the
installation professional. Biamp
recommends that an appropriately
licensed engineer, electrician, or other
professional identify and select the
appropriate conduit, ttings, wire, etc. for
the installation.

DX-IC6LP Only
Installation in a drop (suspended) ceiling with conduit
Prepare the ceiling tile as shown above. Access to the loudspeaker through an adjacent tile space is necessary to install
the cover after the unit is installed in the ceiling tile. The included wiring cover has knockouts on the side and top (1/2" NPT
(21.34mm), M20 (20.0mm), and PG13.5 (20.4mm)). Conduit fittings are not included. Use flexible conduit close to the
loudspeaker to make alignment and connections easier. Run wires and conduit to the loudspeaker locations.
NOTE: DX-IC4LP has only one knockout on the side to maintain a low profile. Conduit use may be required for some plenum
spaces and should also be used in damp spaces. Using input covers with conduit wiring will comply with the City of Chicago
requirements.

6. Thread the cable or wires through the clamp and wire the euroblock
connector as shown. Pay special attention to the labeled polarity.
Loudspeakers may be daisy-chained by using the second set of terminals.
IMPORTANT: Use the provided cable
clamp fitting to secure the wiring to
prevent accidental removal of the
euroblock connector if the wires are
pulled.
Install a cable clamp fitting in one of
the knockouts and run cable through
before wiring the connector. Tighten

9. If necessary, adjust spring
clamps (with a Phillips head
screwdriver) to allow slightly
more space between the rim and
the bottom of the spring clamp
than the depth of the ceiling tile
and C-ring together. The clamps
should all be at the same height.
10. Secure a safety cable to the
seismic safety tab. Make the
cable as short as possible.
Attach the cable to a secondary
structural point directly above the
seismic safety tab to minimize
impact force and swing in the
event of a ceiling failure.
*NOTE: This can also be done
after installing the unit if there is
access in the ceiling.

11. Rotate loudspeaker clockwise as you insert it into the hole. This
collapses the clamps as they move up through the hole (a-d). Once past
the ceiling the clamps will spring out and prevent it from falling.
IMPORTANT: The loudspeaker must be fully supported until the clamps
have moved above the ceiling and returned to their "out" position.
12. Push the loudspeaker up with the rim against the ceiling tile and tighten
the screws (opposing sides rst), to lower the spring clamps to secure it
in the ceiling.
NOTE: Do not overtighten. If the ceiling tile is deformed, the grille may
not stay on.

INSTALLATION OPTIONS
Installation in a drywall [sheet rock] ceiling
Adequate distance above the drywall must be available to accommodate the
depth of the back can.
1. The appropriate size of new construction brackets (SPA-NCxxx) should be
utilized and secured to the ceiling structure (see below).
NOTE: Use a stretched string or laser to align the brackets, rather than
aligning to the truss.
2. Run wiring to each bracket location allowing sucient length to allow for
connection to the back can.
3. A safety cable should be attached to the structure with sucient length to
allow for connection to the back can.
4. Install the drywall and cut out the hole inside the bracket. Allow wires and
cable to hang through the hole or be accessible in the ceiling.
5. After the ceiling is nished, install the loudspeaker (steps 5-12 of this guide
- pages 4-6). Screwing down the spring clamps will secure the loudspeaker
in the ceiling.
6. Finish the installation by setting the tap switch and installing the grille
(steps 13-15 - page 7).

spray (PRF Label O®, Goo Gone® or similar).
2. Pull the grille away from the face. Remove the tether
plug from the face, do not bend the grille.
3. Gently pry the logo from the grille using a non-metallic
tool, or fully mask the logo. Use a sharp knife to
trim the masking material close to the edges of the
masked areas.
4. Remove the grille cloth (scrim material) by spraying all
of the fabric with the adhesive remover.
5. Wait a few minutes to allow the fabric to fully absorb
the spray.
6. Carefully peel o the grille cloth, taking care not to rip
or stretch the fabric.
7. Once the cloth and logo have been removed, some
glue residue may remain on the grille. If so, apply
additional adhesive remover to remove the glue.
8. Thoroughly clean and degrease the grille before
painting. Do not use a solvent (see Cautions above).
9. Paint the grille with several light coats of spray paint
at twice the recommended distance from the grille. Do
not clog the grille perforations with paint.
10. Allow the paint to fully dry and cure.
11. If necessary, reattach the grille cloth. Use a light coat
of simple spray adhesive. Avoid clogging the grille
perforations with any adhesive.
12. Press and smooth the cloth on the grille.
13. Reattach the tether plug.
14. Reattach the logo if required.
15. Attach the grille to the loudspeaker per the installation
instructions.
