RIGGING AND ELECTRICAL SAFETY
IMPORTANT: The loudspeakers described in this manual are designed and
intended to be mounted to differing building surfaces using a variety of
rigging hardware, means and methods. Installation of loudspeakers should only
be performed by trained and qualified 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
amplifier. Always make sure that all power amplifiers 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 qualified personnel. It is strongly recommended that a licensed
and certified 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-IC 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
NOTE: All electrical installation connections for loudspeaker lines are subject to all applicable governmental building and fire 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, fittings, wire, etc. for the installation.
Installation in drop (suspended) ceiling (typical)
-
Run wires to the loudspeaker locations.
-
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.
-
Place the tile rails on the grid and fit the C-ring tabs onto the rails.
-
Reinstall the ceiling tile and align C-ring with the opening.
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 (22.2 mm [0.875″]). 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 only has 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 the cover with conduit wiring will comply with the City of Chicago requirements.
Install the loudspeaker in the ceiling
The cover acts as a strain relief for wiring connections. -
Remove one of the knockouts from the cover and install the cable clamp.
-
Thread the cable or wires through the clamp and wire the euroblock connector as shown in Figures 1 and 2. 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 the clamp after the cover is installed to secure the wires. -
Install the cover as shown (a-b) and secure by tightening the circled screws (c) (Figure 3).
-
Tighten the clamp screws around the cable to provide strain relief.
-
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.
-
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.
-
. Rotate loudspeaker clockwise as you insert it into the hole. This collapses the clamps as they move up through the hole (Figure 5 [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. -
Push the loudspeaker up with the rim against the ceiling tile and tighten the screws (opposing sides first), to lower the spring clamps to secure it in the ceiling (Figure 5-e).
NOTE: Do not overtighten. If the ceiling tile is deformed, the grille may not stay on.
IMPORTANT: For closed ceiling applications all connections (wiring and safety cable) must be made with the input cover installed before inserting the unit in the ceiling.
Set Power Tap -
Set tap switch by rotating knob to the desired setting. (DX-IC6 shown in Figure 6).
Install Grille -
Fully insert the grille plug attached to the grille’s safety tether into the empty hole in the loudspeaker face (Figure 7).
-
Place grille against the face. The magnets will hold it in place. Make sure the grille is fully seated on the loudspeaker face.
INSTALLATION OPTIONS
Installation in a drywall [sheet rock] ceiling
Adequate distance above the drywall should be available to accommodate the
depth of the back can.
| Model | Fits |
|---|---|
| SPA-NC300 | DX-IC4, DX-IC4LP |
| SPA-NC400 | DX-IC6 |
| SPA-NC500 | DX-IC8 |
| SPA-NC600 | DX-IC10, DX-IC10SUB |
-
The appropriate size of new construction brackets (SPA-NCxxx) should be utilized and secured to the ceiling structure (Figure 8).
NOTE: Use a stretched string or laser to align the brackets, rather than aligning to the truss. -
Run wiring to each bracket location allowing sufficient length to allow for connection to the back can.
-
A safety cable should be attached to the structure with sufficient length to allow for connection to the back can.
-
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
-
After the ceiling is finished, install the loudspeaker (steps 5-12 of this guide – pages 4-6). Screwing down the spring clamps will secure the loudspeaker in the ceiling
-
Finish the installation by setting the tap switch and installing the grille (steps 13-15 – page 7).
LOUDSPEAKER REMOVAL
If there is a wired conduit connection to the loudspeaker, it must be
disconnected first, by removing the cover and terminal block.
Follow steps below to remove the loudspeaker from the ceiling (Figure. 9).
-
Pull the grille down until the magnets let go, and let it dangle from the tether.
-
Loosen the spring clamps by turning each screw counter-clockwise until it stops. The spring clamp will travel up the screw and turn against the can. Repeat for all screws.
CAUTION: The loudspeaker must be fully supported as the spring clamps are turned to prevent it from falling as the spring clamps move up and in. -
Remove the loudspeaker from the ceiling. Detach the safety cable (and wiring, if it wasn’t removed previously).

PAINTING INSTRUCTIONS
The grille may be painted to match room decor. Do NOT paint the grille when on the loudspeaker. Remove the scrim material (cloth) prior to painting.
- Purchase a citrus-based label/adhesive remover spray (PRF Label Off®, Goo Gone® or similar).
- Pull the grille away from the face. Remove the tether plug from the face, do not bend the grille.
- 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.
- Remove the grille cloth (scrim material) by spraying all of the fabric with the adhesive remover.
- Wait a few minutes to allow the fabric to fully absorb the spray.
- Carefully peel off the grille cloth, taking care not to rip or stretch the fabric.
- 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
- Thoroughly clean and degrease the grille before painting. Do not use a solvent (see Cautions above).
- 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.
- Allow the paint to fully dry and cure.
- If necessary, reattach the grille cloth. Use a light coat of simple spray adhesive. Avoid clogging the grille perforations with any adhesive.
- Press and smooth the cloth on the grille.
- Reattach the tether plug.
- Reattach the logo if required.
- Attach the grille to the loudspeaker per the installation instructions
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 finish.
Some are also toxic and highly flammable.
IMPORTANT: Do not bend or damage the grille on removal or reinstallation.
IMPORTANT: Blocking the grille holes with paint or getting any paint on
the drivers or internal parts will affect loudspeaker performance and void the
warranty
