CCL5T: How To Set Up, Wire & Install

Introduction

This guide will walk you through setting up your Rockville CCL5T 5" 70V commercial ceiling speakers. The package includes four speakers, making it ideal for restaurants, offices, gyms, and many other commercial spaces. These speakers are available in both black and white finishes.

Even if you’re new to 70V systems, the steps below are simple and easy to follow. All you’ll need are the included cutout guide, a blade for cutting, and speaker wire for connections.

Step-by-Step Instructions

1. Understanding 70V Systems

• A 70V amplifier allows you to connect many speakers (even 100+) from one amp.
• Each speaker is tapped to a specific wattage (e.g., 1.25W, 2.5W, or 5W).
• The total wattage tapped across all speakers must not exceed the amp’s wattage.
  • Example: If your amp is 100W, you can run 20 speakers at 5W each.

2. Cutting the Ceiling Hole

1. Take the included cutout guide and place it where you want your speaker installed.
2. Use tape to hold the guide in place if needed.
3. Cut the hole carefully with a blade, following the outline.

3. Installing the Speaker

1. Push up the spring retainers on the sides of the speaker.
2. Place the speaker into the cut hole.
3. Release the spring retainers to lock the speaker in place.

4. Wiring the Speaker

• Connect the black wire to the negative/common terminal.
• Connect the positive wire to your chosen tap (1.25W, 2.5W, or 5W).
• Example: If using 10 speakers on a 50W amp, use the 5W tap for each speaker.

5. Parallel Wiring (Daisy-Chaining) Multiple Speakers

1. Connect the first speaker’s negative terminal to the negative terminal on the next speaker.
2. Connect the first speaker’s positive terminal (tapped wattage) to the positive terminal on the next speaker.
3. Repeat this process for all four speakers.
4. On the last speaker in the chain, run speaker wire to the amplifier:
   • Positive wire → Positive 70V terminal on the amp
   • Negative wire → Negative/common terminal on the amp

6. Final Connection to the Amplifier

• Ensure all speakers are connected in parallel (daisy-chained).
• Double-check that the total wattage tapped across speakers does not exceed the amp’s rated wattage.
• Power on the amplifier and test the system.

Troubleshooting & FAQs

Q: Why are my speakers not producing sound?

• Check that the black wire is connected to the negative/common terminal.
• Make sure the positive wire is connected to a wattage tap, not left unconnected.
• Verify that the amp is powered on and connected to the correct outputs.

Q: Can I mix different wattage taps on different speakers?

• Yes, you can. For example, in larger rooms you may use 5W, while smaller spaces may only need 2.5W.

Q: My amp keeps shutting down. What should I do?

• Add up the total wattage of all speakers tapped. If it exceeds the amp’s capacity, lower the wattage taps per speaker or reduce the number of speakers.

Conclusion

Your Rockville CCL5T 5" 70V ceiling speakers are now installed and ready to deliver clear, consistent sound across your commercial space. By following these steps, you can easily cut, install, wire, and connect the speakers in a parallel configuration for reliable performance.
