3. Installation and Setup

Proper installation is crucial for optimal performance and safety. It is recommended that installation be performed by qualified personnel.

3.1 Preparing the Ceiling Opening

1. Determine Location: Select a suitable location in the ceiling, ensuring adequate clearance behind the speaker for wiring and mounting hardware.
2. Use Template: Place the provided cutout template at the desired location and trace the opening onto the ceiling material.
3. Cut Opening: Carefully cut the opening using an appropriate tool. The recommended cutout diameter is 8.3 inches (210 mm). Ensure the edges are clean and smooth.

3.2 Installing Support Hardware

For secure installation, especially in suspended ceilings, use the C-ring and tile rail supports.

1. Insert C-Ring: Feed the C-ring support backing plate through the cutout opening. Position it so the tabs align with the speaker mounting points.
2. Attach Tile Rails: If installing in a suspended ceiling, attach the tile rail supports to the C-ring and extend them to rest on the ceiling grid rails.

3.3 Wiring Connections

The speaker features a removable locking terminal block for audio input. Ensure the amplifier is turned off before making any connections.

• Identify Terminals: The terminal block is labeled for positive (+) and negative (-) input, and loop-thru connections.
• Connect Speaker Wire: Strip approximately 6mm (0.25 inches) of insulation from the speaker wires. Insert the positive wire into the '+' terminal and the negative wire into the '-' terminal. Secure the wires by tightening the screws on the terminal block.
• Loop-Thru (Optional): If connecting multiple speakers in a distributed system, use the 'Loop Thru' terminals to pass the audio signal to the next speaker.
• Re-insert Terminal Block: Once wired, firmly insert the terminal block back into its receptacle on the speaker.

3.4 Setting Transformer Taps / Impedance

The Control 16C/T-BK includes a multi-tap transformer for 70V/100V distributed systems and an 8-ohm direct mode. Select the appropriate setting using the rotary switch located on the front baffle, accessible by removing the grille.

• 70V System: Choose the desired wattage tap (e.g., 3.8W, 7.5W, 15W, 30W) for 70V systems.
• 100V System: Choose the desired wattage tap (e.g., 7.5W, 15W, 30W) for 100V systems.
• 8 Ohm Direct: Select the '8Ω' position for direct connection to a low-impedance amplifier.

Ensure the amplifier is off before changing tap settings.

3.5 Mounting the Speaker

2. Secure Tabs: Tighten the mounting screws on the front baffle. This will rotate the mounting tabs outwards, clamping the speaker firmly to the ceiling material. Do not overtighten.
3. Attach Grille: Once the speaker is securely mounted, attach the grille by aligning it with the speaker baffle and pressing firmly until the magnets engage.
