How should I place my JBL HLS820 speakers for optimal performance?
Proper placement of the JBL HLS820 speakers is an important step in obtaining the most realistic soundstage possible. For optimum placement, position the speakers so they form a 40-60° angle with your main listening position. These recommendations are a guide, and slight variations will not diminish your listening pleasure.
The JBL HLS820 speakers are video-shielded and can safely be placed near a television.
How do I connect my JBL HLS820 speakers to an amplifier?
Speakers and electronics terminals have corresponding positive (+) and negative (-) terminals. It is important to connect both speakers identically: the positive (+) on the speaker to the positive (+) on the amplifier and the negative (-) on the speaker to the negative (-) on the amplifier. Wiring speakers “out of phase” results in thin sound, weak bass, and a poor stereo image.
What should I do if there is no sound from any of my JBL HLS820 speakers?
If there is no sound from any of the speakers, check the following:
• Receiver/amplifier is on and a source is playing.
• Review proper operation of your receiver/amplifier.
What troubleshooting steps should I take if there is no sound coming from only one of my JBL HLS820 speakers?
If there is no sound coming from one speaker, check the following:
• Check the “Balance” control on your receiver/amplifier.
• Check all wires and connections between the receiver/amplifier and speakers.
• Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut, or punctured.
Why does my JBL HLS820 system shut off when I increase the volume?
If the system plays at low volumes but shuts off as volume is increased, check the following:
• Check all wires and connections between the receiver/amplifier and speakers.
• Make sure all wires are connected. Make sure none of the speaker wires are frayed, cut, or punctured.
• If more than one pair of main speakers is being used, check the minimum impedance requirements of your receiver/amplifier.
What should I check if there is low bass output from my JBL HLS820 speakers?
If you experience low bass output, check the following:
• Make sure the polarities (+ and -) of the left and right “Speaker Inputs” are connected properly.
