2. Setup and Installation
2.1 Unpacking
Carefully remove the loudspeaker from its packaging. Retain all packing materials for future transport or storage.
2.2 What's in the Box
- 1 x JBL Studio 680 Floor Standing Loudspeaker
- 1 x Owner's Manual (this document)
- 1 x Warranty Card
- 4 x Carpet Spikes
- 4 x Feet Pads
2.3 Speaker Placement
Optimal speaker placement is crucial for sound quality. Position the loudspeakers equidistant from your primary listening position. For stereo imaging, ensure the speakers are placed symmetrically in the room. Avoid placing speakers directly in corners, which can overemphasize bass frequencies. Experiment with toe-in (angling speakers towards the listening position) to find the best soundstage.
Attach the included carpet spikes for stability on carpeted surfaces or feet pads for hard floors. This helps to decouple the speaker from the floor, reducing unwanted vibrations.
2.4 Connecting to an Amplifier/Receiver
The JBL Studio 680 is a passive loudspeaker and requires an external amplifier or AV receiver for operation. Ensure your amplifier is turned off before making any connections.
- Use high-quality speaker cables to connect the loudspeaker to your amplifier.
- Connect the positive (+) terminal (red) on the loudspeaker to the positive (+) terminal on your amplifier.
- Connect the negative (-) terminal (black) on the loudspeaker to the negative (-) terminal on your amplifier.
- Ensure all connections are secure to prevent short circuits or signal loss.

3. Operating Instructions
Once the loudspeakers are properly connected to your amplifier or AV receiver, you can begin playback.
- Ensure all connections are correct and secure.
- Turn on your amplifier/receiver and select the desired audio input source.
- Start playback from your audio source (e.g., CD player, streaming device, turntable).
- Gradually increase the volume on your amplifier/receiver to a comfortable listening level.
The JBL Studio 680 loudspeakers are designed for optimal performance with a wide range of audio content. Avoid excessively high volumes for prolonged periods to prevent potential damage to the speakers or hearing.
4. Care and Maintenance
Proper care will ensure the longevity and performance of your JBL Studio 680 loudspeakers.
- Cleaning the Cabinet: Use a soft, dry cloth to wipe the cabinet surfaces. For stubborn marks, a slightly damp cloth can be used, followed immediately by a dry cloth. Avoid abrasive cleaners, solvents, or strong chemicals.
- Grille Care: The speaker grilles are magnetically attached. They can be gently removed for cleaning. Use a soft brush or a lint roller to remove dust.
- Driver Protection: Avoid touching the speaker cones or tweeters directly, as this can cause damage.
- Environmental Conditions: Do not expose the loudspeakers to extreme temperatures, humidity, or direct sunlight for extended periods.
5. Troubleshooting
If you experience issues with your JBL Studio 680 loudspeakers, consult the following common troubleshooting steps:
No Sound from Speakers:
- Verify that the amplifier/receiver is powered on and the correct input source is selected.
- Check all speaker cable connections at both the loudspeaker and the amplifier. Ensure they are secure and correctly matched (positive to positive, negative to negative).
- Confirm that the volume on your amplifier/receiver is not set to minimum or muted.
- Test with another audio source or another set of speakers (if available) to isolate the problem.
Distorted or Unclear Sound:
- Reduce the volume level on your amplifier/receiver. Distortion can occur if the amplifier is overdriven.
- Check speaker cable connections for any loose strands that might be causing a short circuit.
- Ensure the audio source is clean and not distorted.
- Verify that the speaker grilles are not obstructing the drivers or vibrating.
Unbalanced Sound (One Speaker Louder/Softer):
- Check the balance settings on your amplifier/receiver.
- Inspect speaker cable connections for both speakers to ensure they are identical and secure.
- Ensure both speakers are connected to the correct left/right channels on the amplifier.
If these steps do not resolve the issue, contact JBL customer support for further assistance.
