Risoluzione dei problemi

If you encounter issues with your Z-640 system, refer to the following common problems and solutions:

Problema	Possibile causa/soluzione
Nessun suono dagli altoparlanti.	Ensure the system is powered on and the power indicator LED is lit. Check all audio cable connections between the speakers, subwoofer, and your audio source (computer/console). Verify that the volume is turned up on both the speaker system and your audio source. Ensure headphones are not plugged into the center speaker's headphone jack.
Suono debole o distorto.	Check the audio source quality (e.g., low bitrate music files can sound poor). Adjust the volume levels on both the speakers and the audio source to avoid overdriving. Experiment with your sound card's equalizer settings. Ensure speaker cables are fully inserted and not damaged.
No bass or weak bass.	Adjust the "Sub Volume" knob on the back of the subwoofer. Ensure the orange cable (subwoofer/center channel) is correctly connected to your sound card. Check your sound card's settings to ensure the subwoofer output is enabled and configured correctly.
Rear speakers are too quiet or too loud.	Adjust the "Fader" control on the center speaker to balance front and rear volume. Verify the black cable (rear speakers) is correctly connected.
Bright blue LED on center speaker is distracting.	This is a design feature. If bothersome, a small piece of electrical tape can be placed over the LED.
