VOL70200: How To Make A Multi-Room System

Introduction

This guide will walk you through setting up a multi-room audio system using the Rockville VOL7200 volume controller. Whether you are using a single-zone or multi-zone amplifier, this setup will allow you to control audio levels across different rooms easily.

What You Need

• Rockville VOL7200 Volume Controller
• Amplifier (Single-Zone or Multi-Zone)
• Speakers
• Speaker Wire (CL2-rated recommended for in-wall installation)
• Electrical Box (Single-Gang Drywall Ring or Electrical Box with Back Removed)
• Stud Finder
• Flathead and Phillips Screwdrivers
• Saw (Hand Saw or Reciprocating Saw for drywall cutout)

Step-by-Step Installation

1. Choosing the Right Amplifier

Before installation, determine whether you're using a single-zone or multi-zone amplifier:

• Single-Zone Amplifier: Connect the speaker wire to the 70V main output, not the 100V or 8-ohm output.
• Multi-Zone Amplifier: Connect the speaker wire to the output of the specific zone you want to control.
• Ensure the power rating of your volume controller matches the amplifier or zone output (e.g., do not exceed 200W per zone on the Rockville RCS 6506 or RCS 6508).

2. Choosing a Wall Mount Location

• Install the volume controller at the same height as standard light switches for convenience.
• Decide if you want an in-wall or surface-mount installation:
  • In-wall installation (recommended) requires cutting into the drywall.
  • Surface-mount installation may be used in industrial settings.

3. Cutting the Hole for the Volume Controller

1. Check for obstacles behind the wall using a stud finder.
2. Use a single-gang drywall ring as a template to mark the hole.
3. Cut the hole using a hand saw or reciprocating saw.
4. Insert the drywall ring or electrical box and secure it with screws.

4. Running the Speaker Wire

1. Use two sets of speaker wires:
   • One set runs from the amplifier to the volume controller.
   • The other set runs from the volume controller to the first speaker in the chain.
2. Label the wires to keep track of which set connects to the amp and which connects to the speakers.
3. Plan the wiring route, ensuring you have 20-40% extra wire for flexibility.
4. Use CL2-rated speaker wire for fire resistance and safety compliance.

5. Connecting the Speaker Wire to the Volume Controller

1. Remove the Euroblock terminal from the back of the volume controller.
2. Locate the Input and Output terminals:
   • Input terminal: Connect the speaker wire from the amplifier.
   • Output terminal: Connect the speaker wire leading to the speakers.
3. Use a flathead screwdriver to loosen the terminal screws.
4. Insert the speaker wires into the correct terminals and tighten the screws.
5. Reinsert the Euroblock terminal into the volume controller.

6. Mounting the Volume Controller

1. Align the volume controller with the electrical box.
2. Secure it using the long screws provided.
3. Be careful when using a power drill—go slow to avoid damaging the screws or box.

7. Attaching the Faceplate

1. Align the faceplate with the volume controller.
2. Secure it with the provided screws using a flathead screwdriver.

Setting Volume Levels

1. Start by setting the volume controller to 0.
2. Set the amplifier volume to 75-80% for optimal headroom.
3. Use the volume controller to adjust the room’s volume without overloading the amp.
4. If adding another volume controller in a different room, repeat the same steps.
5. Never exceed 650W total power or 200W per zone to avoid damage.

Conclusion

Now you have successfully set up a multi-room audio system using the Rockville VOL7200. This allows for independent volume control across different rooms while keeping your wiring organized and efficient.
