Question about my Logitech z906 5.1

[alexfegan321]

I have the 5.1 logitech z906 system 

 

I normally have this connected to my pc with the green, pink and black cables and it sounds epic. but my pc is at another house.

 

My question is, how come it works pretty decent with just the green cable into my ipad? I mean it only enables 5 of the speakers but it still works, sounds decent and subwoofer is enabled.

 

Can someone help explain these 3 cables and then recommend a decent adapter for when i do want to connect it to something else other than my pc into the motherboard lol

1 cable just gives you stereo (left and right channel).
But the Logitech system has built in detection and if it just sees stereo it will automaticly fill it to the rest of the speakers. (a sort of fake surround).

 

If you connect them with 3 cables you have your front left and right your back left and right en the last one is centre and subwoofer.
But the subwoofer wont work cus it uses the data from the stereo channel to make its own subwoofer sound. (Why you choose always full rang when setting it up in windows)
And when there needs to be sound from the back or centre the computer will send it to the right channel directly.

Thanks bro, I agree, it is like two main ones are working, and the other two get fake sound, and one is off, but I mean for short notice and one cable, 2 speakers and bass is more than enough for this new eminem album lol. thankyou

Yup, Logitech does now how to make them work with lots of stuff.
Enjoy your most likely booming sound.

Youd be surprised lol, only thing that seems off is the choice in how loud it makes the words to sub ratio, sub itself doesnt sound much different? more like instruments but im not an audio guy as you can tell lol

Sorry  to digging up old thread.
Enable full rang in settings apply for all sound system which ever use the 3cable or just specific for z906?
Coz i searched about it & suggest only for if the satellite speaker have their own bass system.

It is common for a subwoofer to take a common 2 channel stereo signal and use a LPF or low pass frequency cross over to extract only the frequencies required for the subwoofer.  For all extents and purposes a dedicated sub channel is not required, that is considering that your stereo signal is full range and not set to a small speaker subset.

Small satellite speakers should not be set to full range when configuring them for surround sound in Windows

z906 speaker is also small, doesn't it?

Not with most Logitech surround sets.
By choosing the small speakers you let Windows do the cross-over for the subwoofer.

Thats not how it works with those Logitech products!

They just use the main left right channel and take the lower frequencies from there and send it to the sub.

The actual sub-channel will not be used. (Probably so they can have a working subwoofer with only stereo signal).

With the unit I had back in the day there was a mixer setting to pump a stereo signal through everything, but turning it off you'd still want the windows center/sub channel configured properly. Do newer units do this differently?

I have the Ancient Z5500 (picture below).

On that i have a setting to take 3x stereo or 1x surround.

Since on PC i'm using 1x surround, and i could just disconnect my center/sub cable and still the sub would work.

 

Since Windows is absolutely awful with sound management, its a good thing, when you play anything from your browser its stereo anyways and would mean with lesser systems you have no subwoofer sound.

 

Thats why many use aftermarket sound-cards that have a crossover setting available.

I know the Realtek onboard cards will NOT let you do that.

 

I don't know about newer setups, but i know most surround stuff from Logitech does it this way. Even the cheaper ones.
