you have almost diagnosed your problem…
the problem with these lowfi and hifi home systems is, that they have their stereo speakers with multi speaker configuration in their boxes so that even 2 speakers give an illusion of surround sound. however optical is providing a full surround signal which either the aiwa unit canot decode or is bypassing the frequency range it canot proces and reproduce accurately.
your easiest options is that you try connection using analogue cables like RCA and other non digital connections… those are stereo signals only so you should get proper clean sound.
PS: your speakers are too loarge for your unit… in future try getting a proper amp with atleast 100W out per channel.
Thanks for the detailed answer Farhan.
I was also thinking about the same solution because i guess we can’t control this decoding using remote of TV, Setup Box or the Unit itself. Today i checked the Setup box and it has a 3mm jack written AV on it. I’ll use this connection instead. Bye Bye Digital connection
PS. You nailed it man. I know its only 30 Watt amp and speakers are 150 watt. Actually my original amp got burned by my friend using 220 Volt input and then i got this one in replacement. At that time prime requirement was to get optic input it is not required anymore. But i’ll get bigger amp now.
BTW. What would be the negative effect of using small amp on big speakers?
