4. Setup

4.1 Speaker Placement

Proper placement of your center channel speaker is crucial for optimal sound imaging and dialogue clarity in a home theater system. The center channel speaker is primarily responsible for reproducing dialogue and on-screen sound effects.

  • Location: Position the center channel speaker directly above or below the center of your television or projection screen.
  • Height: Ideally, the tweeter of the center channel speaker should be as close to the height of the main left and right speakers' tweeters as possible, and at or near ear level when seated.
  • Distance: Ensure the speaker is placed at an equal distance from the primary listening position as your main left and right speakers to maintain proper sound staging.
  • Clear Path: Avoid placing objects in front of the speaker that could obstruct the sound.

4.2 Connecting to Your Receiver

The JBL Stage 2 245C is a passive loudspeaker and requires connection to an audio/video (AV) receiver or amplifier. Use high-quality speaker wire for the best performance.

  1. Power Off: Ensure your AV receiver/amplifier is turned off and unplugged from the power outlet before making any connections.
  2. Identify Terminals: Locate the speaker terminals on the back of your JBL Stage 2 245C speaker and on your AV receiver. The terminals are typically color-coded (red for positive +, black for negative -).
  3. Prepare Speaker Wire: Strip approximately 1/2 inch (12mm) of insulation from the ends of your speaker wire. Twist the bare strands tightly.
  4. Connect to Speaker: Connect the positive (+) terminal of the speaker to the positive (+) center channel output terminal on your receiver. Connect the negative (-) terminal of the speaker to the negative (-) center channel output terminal on your receiver. Ensure no stray wire strands are touching each other or other terminals, which could cause a short circuit.
  5. Verify Polarity: Maintain consistent polarity for all speakers in your system (positive to positive, negative to negative) to ensure proper phase and sound reproduction.

Refer to your AV receiver's manual for specific connection instructions and speaker setup procedures.

5. Operating Your Speaker

As a passive speaker, the JBL Stage 2 245C does not have its own controls. Its operation is managed entirely through your connected AV receiver or amplifier.

  • Power On/Off: Turn your AV receiver on or off as usual. The speaker will receive power and audio signals from the receiver.
  • Input Selection: Select the desired audio/video input on your receiver for your source device (e.g., Blu-ray player, streaming device).
  • Volume Control: Adjust the overall system volume using your receiver's volume control.
  • Speaker Level Calibration: For optimal performance, use your AV receiver's automatic speaker calibration feature (e.g., Audyssey, MCACC, YPAO) if available. This will set appropriate levels, distances, and equalization for your center channel speaker within your listening environment.
  • Break-in Period: Like many loudspeakers, your JBL Stage 2 245C may benefit from a break-in period of several hours of normal use. During this time, the drivers will loosen up, potentially leading to a more refined sound.

6. Maintenance

Proper care will help maintain the appearance and performance of your JBL Stage 2 245C loudspeaker.

  • Cleaning the Cabinet: Use a soft, dry cloth to wipe the cabinet surfaces. Avoid using abrasive cleaners, waxes, or solvents, as they may damage the finish.
  • Cleaning the Grille: The fabric grille can be gently vacuumed with a soft brush attachment to remove dust. If necessary, it can be carefully removed and hand-washed with mild soap and water, then allowed to air dry completely before reattaching.
  • Driver Care: Avoid touching the speaker cones or tweeters directly, as this can cause damage.
  • Environmental Conditions: Keep the speaker away from extreme temperatures, high humidity, and direct sunlight.
