ROCK SHAKER 6.5: How To Set Up 6.5" Powered Home Theater Subwoofer

Introduction

The Rockville Rock Shaker 6.5 Powered Subwoofer enhances low-end sound for home theater systems, audio interfaces, and recording setups. This guide will walk you through setting up your subwoofer, including connections to a home theater receiver, powered speakers, and an audio interface.

Step 1: Connecting to a Home Theater Receiver or Amplifier

Option 1: Using RCA Line Outputs (Recommended)

1. Locate the RCA sub output or line output on your home theater receiver or amplifier.
2. Take an RCA cable and plug one end into the receiver’s sub output.
3. Plug the other end into the RCA Line Input on the back of your Rock Shaker 6.5 subwoofer.

✔ This method provides the best sound quality and cleanest signal.

Option 2: Using High-Level Speaker Wire Inputs (For Receivers Without RCA Outputs)

If your receiver or amplifier does not have RCA outputs, you can connect via high-level speaker wire inputs:

1. Take two sets of speaker wires.
2. Connect one end to the speaker output terminals on your amplifier (Front A or B terminals).
   • Red wire → Positive (+) terminal
   • Black wire → Negative (-) terminal
3. Connect the other end to the High-Level Input terminals on the back of the subwoofer.
   • Left terminal on the amp → Left input on the subwoofer
   • Right terminal on the amp → Right input on the subwoofer
4. To complete the chain, connect additional speaker wires from the High-Level Output terminals on the subwoofer to your front speakers.

✔ Use this method only if your amplifier lacks RCA outputs.

Step 2: Adjusting the Subwoofer Settings

• Power Switch: Turn the subwoofer on or off.
• Volume Knob: Controls overall subwoofer volume.
• Frequency Knob (Low-Pass Filter):
  • Adjusts which frequencies the subwoofer plays.
  • Example: Setting it to 75Hz allows only sounds at 75Hz and below to come through the sub.
  • Tune based on your preference and speaker setup.
• Phase Switch (0° / 180°):
  • If the bass sounds out of sync, switch between 0° and 180° to align the subwoofer with your main speakers.
  • Useful when using two subwoofers.
• Auto Power Mode:
  • When turned on, the subwoofer automatically turns on when it detects a signal.
  • It turns off after 15 minutes of inactivity to save power.
• RCA Line Output:
  • Used to connect additional speakers or subwoofers to expand your setup.

Step 3: Optimizing Subwoofer Placement

• For maximum bass response, place the subwoofer near a wall or in a corner.
• Experiment with placement to find the best balance for your room.

Step 4: Connecting to an Audio Interface for Recording & Mixing

If you're using the Rock Shaker 6.5 subwoofer in a studio setup, follow these steps:

Connecting the Subwoofer to the Interface

1. Connect your audio interface to your computer via USB.
2. In your computer’s sound settings or DAW, set the input/output device to your interface.
3. Use an RCA to dual ¼-inch cable:
   • Plug the ¼-inch ends into the left and right outputs of your audio interface.
   • Plug the RCA ends into the RCA input of the subwoofer.
4. Connecting Studio Monitors (Full-Range Sound):
   • Take an RCA cable and plug one end into the RCA Output of the subwoofer.
   • Plug the other end into the RCA input of your studio monitors.

Step 5: Fine-Tuning Your Studio Sound

• Turn on your subwoofer and speakers.
• Adjust the volume knob and frequency knob on the subwoofer.
• Use the main mix knob on your interface to control overall volume.

✔ You can also connect the speakers to the interface first and the subwoofer second, depending on your setup preferences.
