CC525T: How To Set Up, Install & Use

Introduction

The Rockville CC525T 70V Commercial Ceiling Speakers are perfect for restaurants, offices, retail spaces, houses of worship, and other commercial installations. These speakers operate on a 70V system, allowing you to run multiple speakers on a single amplifier while controlling the wattage per speaker.

This guide will walk you through:

• How 70V systems work
• Installing the CC525T speakers
• Wiring and setting tap options
• Connecting them to an amplifier

Understanding 70V Speaker Systems

A 70V system allows you to connect multiple speakers to a single amplifier without worrying about impedance matching. Instead, each speaker draws a fixed wattage from the amplifier based on the tap setting.

Example:

• If your amplifier provides 100W, you can run:
  • 10 speakers tapped at 10W each, or
  • 20 speakers tapped at 5W each

This efficient power distribution allows for large-scale installations without overloading the amp.

Step 1: Cutting the Ceiling Hole for Installation

Each CC525T speaker comes with a cutout template to simplify installation.

1. Use the provided template to mark the hole location on the ceiling or drop ceiling tile.
2. Cut along the marked circle using a drywall saw or similar tool.
3. Insert the speaker into the hole and remove the grille using the included tool.
4. Secure the speaker by tightening the screws with a Phillips screwdriver.

Tip: The speaker grilles are paintable to match any ceiling.

Step 2: Setting the Speaker Tap

On the back of the speaker, you'll find the 70V tap selector, which determines how much wattage the speaker pulls from the amp.

1. Choose a tap setting:
   • 2.5W, 5W, 10W, 15W, or 20W for 70V mode
   • 8-ohm mode (for traditional setups with standard amplifiers)
2. Turn the dial to the desired wattage.

Tip: If using multiple speakers, ensure their combined wattage does not exceed the amplifier’s power capacity.

Step 3: Wiring the Speakers in Parallel

70V speakers are wired in parallel. This means:

• All positive terminals connect to the next speaker’s positive terminal.
• All negative terminals connect to the next speaker’s negative terminal.

Steps to Wire the CC525T Speakers:

1. Take the red (positive) wire and insert it into the positive terminal of the first speaker.
2. Take the black (negative) wire and insert it into the negative terminal.
3. If wiring multiple speakers, daisy-chain the positive wire to the next speaker’s positive terminal, and repeat for the negative wire.
4. Continue this pattern until all speakers are connected.
5. Run the final speaker’s wires back to the amplifier.

Tip: Using multi-zone amplifiers allows for independent volume control for different areas.

Step 4: Connecting to the Amplifier

1. Ensure your amplifier supports 70V output.
2. Match the total speaker wattage to the amplifier’s output capacity.
3. Connect the speaker wires:
   • Red wire to the 70V terminal on the amp
   • Black wire to the common (COM) terminal on the amp
4. Power on the amplifier and adjust the volume levels.

Step 5: Adjusting the Aimable Tweeter

Each CC525T speaker has an adjustable tweeter to direct sound where needed.

1. Gently angle the tweeter toward the listening area.
2. Adjust for even sound coverage in the room.

Tip: This is especially useful in restaurants or offices where sound needs to be directed toward specific seating areas.

Conclusion

The Rockville CC525T 70V Ceiling Speakers provide crystal-clear audio, flexible wattage settings, and easy installation. Whether you’re setting up a small café or a large commercial space, these speakers allow you to create a professional audio experience.
