Question about Logitech Z-680 Computer Speakers

2 Answers

Z-680 optical acting very strange

I unplugged my Mac G5, where my Z-680 system had been working superbly, and moved it all into a new office, where I carefully reassembled everything. For some reason, my Z-680 now no longer produces sound. I've checked system settings, volume/mute issues, optical in vs. out, etc. My speaker test works fine; they're all plugged in and operational. But when I power up the Mac, the speakers start making weird popping and rumble noises, sounding sort of like an electrical storm. And needless to say, none of the system audio works at all through the Z-680 now. Any ideas? Could it be that my optical cable is bad? It looks like brand new, but who knows? Thanks for the help.

    I just replaced the cable tonight and yes indeed, the old one was bad after all. Everything's fine now. Thanks anyway!

I had a problem something similar - once reconnected my rear speakers stopped working, i could hear "hiss" from the speakers very low but no sound whatsoever so i tried the combination of "INPUT + SETTINGS" hold for a couple of seconds and this resets all settings plus shows FIRMWARE. all back to normal after, my rear speakers started working again. i hope this helps others in the future.

How do I update my wireless mouse?


try updating the mouse drivers. Go to the Verbatim manufacturer website, search your model of mouse and download the latest driver. To update drivers on windows go Control panel>device manager>mice/input device then right click your mouse and update driver software. If the mouse continues to play up even though it works on other computers then the mouse is probably incompatible with your operating system.

I'm using a new mac pro 5.1 and this method works best for me. Turn off your computer unplug your bose companion 5 and the usb cable as well. Unplug keyboard usb plug it in the front of your tower, plug back your bose system and usb cable voila. From now on you'll never have problems ever again :D

Can i use these on a macintosh G5 powermac? the sound is very low and i need something louder but hard to know if these would suit my old mac. thanks


These are basic speakers and can be used on any computer, game system or anything other type of equipment with a stereo plug. You can plug these in the audio out jack or the headphone jack and they should work fine.

I unpluged back left speaker, forgot to turn off the power and the wire somehow droped down on the floor and smell burn with sound of shot circuit between + and - , after that my speaker does not make any...


Sorry, once there is short circuit happened in one of the component of a set devices mainly your surround sounds speakers and since they are all interconnected of there will be a chain reaction, one short circuit runs through the other device and then another short circuit will happen.

To make it short, if your speakers still have a warranty contact the manufacturer for support and most probably parts replacements.

If all else fails, purchase a new one...

Please never forget that on all electrical and electronic devices, especially home appliances, NEVER PULL OUT THE PLUG IF ITS TURNED ON, TURN IT OFF FIRST.

Hope these helps.

Feedback sound


If moving the microphone doesn't work then suspect "microphonics" where a loose electronics component is vibrating and acting as a microphone. Could be cable. Unplug all microphone cables, still feedback? Right click speaker icon, sound properties, temporarily disable computer sound input devices. If still feedback then analog section of sound card (or motherboard sound chip) or your speaker system.

Volume dial not working


i would recommend you ask logitech if they can fix it, if the cost is too high i would go look for other stores that fix speakers, if it still cant be fixed, your better off buying new ones because having speakers like those for 5 years is a long time, it may just be time to change

BA7500g speakers won't work with my mac


I have the same problem except i'm using a macbook and i'm trying to connect the speakers. My macbok accommodates optical digital audio output, but you have to buy a  a standard toslink cable with a toslink mini-plug adapter.  Since the speaker input is a digital coaxial (not fiber, optical) you have to buy a Digital Fiber Optical (Toslink) to Digital Coaxial (S/PDIF) Converter.  good luck. hope this helps
