UNPACKING

Open the box, and take out the speaker. If you notice any defects in one of the elements as you unpack, please get in touch with your reseller. Before disposing of the packaging, make sure there is nothing left inside. Each box contains :

• SECRET speaker
• Grill
• User manual
• Cutting pattern
• Tool to dismount the grill (hook) - Except LCR7

PREPARATION

The custom installation speakers of the SECRET range are designed to be installed in walls or ceilings. To do so, you will need to make an opening in the partitions where the speakers can be installed. The following table indicates the dimensions of the openings and the installation depth needed for the installation:

opening depth

	ICT4 ICT5	ICT7/7+	EMT7	ICT8	IWT7	IWT8	LCR7
Needed opening	6.69"	6.93"	8.11"	7.9"	9.64"			10.67 × 6.61"	13.3 × 8.5"	14.48" × 7.48"
Minimum installation depth	2.75"	3.03"	3.58"	3.3"	4.17"		3.42"	3.9"	3.9"

Before drilling, you should make sure the locations chosen in the wall/ceiling are free of obstructions such as pipes, ducts or wiring that will interfere with the installation.

Using the supplied pattern, draw a line on the wall/ceiling, then cut the shape using an appropriate tool.

In the event you wish to receive more informations about the installation of your SECRET speakers, you should contact your TRIANGLE reseller.

SPEAKER PLACEMENT

The SECRET range speakers have been developed to guarantee a high quality sound in most environments. In order to ensure the best possible listening experience, it is advisable to follow certain recommendations depending on the type of use wanted.

As a general rule, avoid placing the speakers too close to a corner or an obstacle (e.g. a pillar, etc.), that could affect the acoustics by creating unwanted reflections.

Stereo setup

For a stereo setup, the SECRET speakers should be located between 9 and 16 feet apart, on a symmetrical basis from the main listening position.

Home theater setup

To use the SECRET speakers in a home theatre setup, the front and center speakers must be located approximately 2 ft in front of the screen. The IWT in-wall speakers must be put on the sides, under the screen, or behind, if the screen is acoustically transparent. The rear speakers must be placed close to the main listening position.

CONNECTION

The speakers of the SECRET range are fairly easy to install. To ensure an optimal installation, please follow these steps carefully.

First, ensure you route the cables through the wall/ceiling in order to connect your SECRET speakers to the amplifier. Leave some spare cables to ease connecting them to the terminals on the back of the speaker. The maximum cable diameter accepted by the terminals is 4.5mm.

Use high-quality cables: the length of the cables needed for this type of installation is important. It is therefore necessary to use cables that least influence the speaker's signal dynamics, type 2 × 2.5 ~mm^2 in OFC.

Strip the cable, and then connect it to the spring terminal. Ensure that the speaker connexion polarity is correct: the cable of the positive terminal on the amplifier must be connected to the red terminal, the cable of the negative terminal must be connected to the black terminal.

INSTALLATION ICT - IWT - LCR

Once the speaker is connected, ensure that the tightening hooks are placed so they don't stop the speaker from entering into its allocated slot. Insert the speaker into the partition in a manner so the edge is at the level with the wall/ceiling. Beware not to trap the cables during the installation.

Then, secure the tightening hooks to fasten the speaker with a cross-head screwdriver. Be careful not to damage the speaker membrane during handling. Do NOT use electric screwdriver which could damage the clamping hooks if the torque is incorrectly adjusted.

Finally, install the magnetic grill on the front of the speaker.

The speaker is ready for use. To remove the grill, use the dismounting tool that is supplied. For more discretion, the grill can be painted. Use the provided hook, remove the white fabric and preferably use a spray paint for an optimal result.

Note that the bass and treble level of IWT & LCR can be adjusted according to your needs by using the available switches: 0 / -3 dB for ITW models and 0 / -2 dB for LCR.

INSTALLATION EMT

Once the speaker is connected, ensure that the tightening hooks are placed so they don't stop the speaker from entering into its allocated slot.

(A) Insert the speaker into the partition in a manner so the edge is at the level with the wall/ceiling. Beware not to trap the cables during the installation.

(B) With one hand hold the outer rim of the in-ceiling mount, with the other hand rotate clockwise the center part of the speaker using the three center arms. This will lock the speaker onto your ceiling. (C).
