INSTALLATION PLANNING

First, find a suitable location to set-up the C25. It is best to put the

amplifier in a stable location near other equipment to be used.

It can be set in a cabinet, on a tabletop, or mounted on the wall. The

C25 may be wall-mounted using the integrated mounting holes.

Appropriate mounting hardware should be purchased locally.

Location in the Classroom

Connecting the Power Supply

• Locate the power supply and AC power cord.

• Connect the AC power cord into the DC power supply.

• Insert the DC connector into the “Power” port on C25 and plug the other end to an electrical outlet.

• The C25 automatically powers on and the white Power light on the front panel will turn on.

• A network connection is required for network communication when using the DC power supply.

Power over Ethernet: PoE+

• Locate network switch that can support PoE+ power.

• Insert PoE+ Ethernet Cable into the “Ethernet” port on C25 and the other end to the

network switch.

• The C25 automatically powers on and the white Power light on the front panel will turn

on.

• If the C25 is connected to a network switch with PoE+ ports and the DC power supply is

also used, the C25 will be powered by the DC power supply.

TCQ Speaker Installation

SYSTEM COMPONENTS AND UNPACKING

• (1) Ceiling grid T-bar (US & Canada use)

• (1) 50  (15m) plenum rated speaker wire (If ordered)

• (1) 19  (6m) coil safety wire

• (4) Self drilling screws (outside U.S. and Canada)

NOTE: Wiring should follow the class 2 wiring methods as outlined in the National Electric Code.

SELECTING SPEAKER MOUNTING LOCATIONS

One TCQ speaker will distribute sound throughout a classroom of up to 1,200 sq 

(112 sq m). The location of the speaker is important to ensure even sound distribution.

Ceiling height should be 9 - 12  (2.75m - 3.75m).

1. Identify the center of the of the classroom for optimum location.

2. Select a ceiling tile that is free from fixtures (lighting, HVAC, etc.) within a 6  (1.8m)

radius nearest to the center point.

3. Remove the selected ceiling tile for speaker installation.

The dimensions of the TCQ are 1’ x 2’. It is designed to fit into any

standard 2’ X 4’, or 2’ X 2” suspended ceiling tile grid.

1. The ceiling tile will need to be cut to accommodate the TCQ

2. Set the ceiling tile on a flat work surface with the patterned side

facing down.

3. Using a straight edge, cut a 1’ x 2’ section from the ceiling tile,

creating a 1’ x 2’ section and a 3’ x 2’ section, or two 1’ x 2’

sections depending on the size of your tiles.

4. Locate the 2’ ceiling grid t-bar attachment. Locate the

attachment slots in the existing ceiling grid and snap the new

T-bar into place to create a 1’ x 2’ and 2’ x 3’ sections, or two 1’ x

SECURING THE TCQ SPEAKER (U.S. & CANADA ONLY)

To comply with Building Codes, the TCQ MUST be secured to the building

structure with two safety wires.

1. Locate the safety wire. The safety wire needs to be permanently attached to the

solid building structure with metal clips, tie point studs, concrete anchors or eye

screws designed for the specific structure material. The specific anchors will need

to be provided by the installer.

2. Cut the safety wire in half.

3. Install the appropriate anchor into the building structure (see figure 6).

4. Loop one end of the safety wire through the anchor (or eye screw), then twist it

around itself at least five times. Repeat for the second anchor tie point.

5. Place the TCQ into the desired grid location.

Caution: Make sure the TCQ is stable on the grid rails with side brackets capturing

the T-bar grid. If not stable, there could be a danger of it falling until safety wires

are attached.

6. Loop the other end of the safety wire through one of the tabs on the TCQ (located

in opposite corners). Pull the wire through until it is taut and twist it around itself

at least five times to secure the TCQ and cut o any excess wire if needed (see

figure 7).

7. Repeat with securing the second safety wire to the other tab.

SECURE TCQ TO CEILING RAIL WITH SELF-DRILLING SCREWS

1. Locate the four (4) self-drilling sheet metal screws.

2. Utilizing existing holes on the vertical section of the ceiling rail

(center of the hole to the base of the rail must be a minimum

of 0.6”, drill two screws on each 2’ side of the TCQ (see figure

8). Drilling these screws into the designated areas of the TCQ

chassis will not cause harm to the product.

NOTE: Do not drill in the area designated with yellow tape as

this could aect audio quality and void the warranty.

1. Find and open the front panel door on the TCQ by sliding the

door toward the end of the TCQ to disengage the lock (see

figure 9A).

2. Run speaker wire through back of speaker and into the

terminal block area. Use appropriate conduit connector or

cable bushing/grommet (not supplied) as needed for the 1/2”

opening (see figure 10).

3. Attach the two wires to the terminal block screws as indicated

(see figure 11). Spade lugs are provided that can be attached

to the speaker wire, if desired.

4. Close speaker door securly by applying pressure outward on

the main body of the TCQ. Then slide the door toward the

middle of the unit and lock into place (see figure 9B).

5. To continue with installation, go to Page22: Connecting Wire

to Amplifier.

FOR MM X MM CEILING GRID

To comply with Building Codes, the TCQ MUST be secured to the building

structure with two safety wires.

The TCQ has spacer brackets mounted on each of the four sides. With these brackets

installed, the TCQ will fit a standard 2’ x 2’ suspended ceiling grid. With the brackets

removed, it will fit a 600mm x 600mm ceiling grid.

Remove the spacer brackets from each of the four sides of the TCQ. Replace the two

screws into the woofer end of the speaker cabinet to ensure proper audio quality

Note: If your ceiling grid is any other dimension than mentioned above, contact your

local Lightspeed representative.

1. Locate the 6m length of safety wire. The safety wire needs to be permanently

attached to the solid building structure with metal clips, tie point studs, concrete

anchors or eye screws designed for the specific structure material. The specific

anchors will need to be provided by the installer.

2. Cut the safety wire in half.

3. Install the appropriate anchor into the building structure (see figure 1).

4. Loop one end of the safety wire through the anchor (or eye screw), then twist it

around itself at least five times. Repeat for the second anchor tie point.

5. Place the TCQ into the desired grid location.

Caution: Make sure the TCQ is stable on the grid rails with side brackets capturing

the T-bar grid. If not stable, there could be a danger of it falling until safety wires

are attached.

6. Loop the other end of the safety wire through one of the tabs on the TCQ (located

in opposite corners). Pull the wire through until it is taut and twist it around itself

at least five times to secure the TCQ and cut o any excess wire if needed (see

figure 2).

7. Repeat with securing the second safety wire to the other tab.
