Please run the YPAO room calibration. Set the volume knob at the sub to mid position when you do this.
Take some time and read the manual on how to do this correctly.
After this calibration set the speakers to small and the cross-over to 80Hz or 100Hz for the sub.
You may also be sitting in a null position. Try the sub crawl to find the best position.
Set the phase to normal during the initial set up.

Setting the gain to max for the sub at the avr will give a lot of distortion and no head room.
Try and achieve 0dB or -2dB for the sub after calibration. This will mean adjusting the volume level at the sub and re running YPAO calibrtion until you get the desired level.

This may all sound confusing and steep learning curve but once you have done it, it is rather simple.

Thankyou so much for advising everyone. But this is so complicated man. Those setup izzit in Setup --> Speaker Config. Everything inside ?

You should at least read the manual book once to know what functions and setting it has. Then refer back when you encounter a problem.
99% of info are in the manual book.
Stuff like these are never 'Plug ad Play'.
And its really a waste of money just to sell it off just because you dunno how to set it.

Some ppl like me only dream to have a system like yours

I know. But the manual comes with a CD. Is not a book. Plus my Pc monitor died. Thats y. lolz.

Azbro u wake up so early ho everyday !XD

umm... your PC monitor died so you can't read the PDF file but you can still surf and post stuff on Lowyat.net?

Anyway... I'm still curious as to what your reference audio files are.. Playing from CD? MP3? Watching DVDs?

lol bro. I using my office pc. thats y cant bring any cd or usb lolz

even picture that u guys attached i also cant view.

Now my plan is:

Since i still have no budget to buy new plasma TV

So i decide to buy a LCD monitor bout 22 - 24 inches.
Then, output HDMI from my PC to LCD monitor to play DVDs or MP3. I dont really use DVD player to watch movie. Coz my DVD player very cakai one = =

Oh... I see...

Umm... HDMI from a PC to a 24" LCD Monitor for MP3? How about your Yamaha set?

Bro just went to lawyat to grab the new Samsung LCD BX2231 with HDMI. But still confuse for the setting lolz..

I try to OUTPUT the HDMI from my PC into the YAMAHA AMP. After that i OUTPUT from AMP to LCD. Will it works ?

Of course it will work lah...provided your setting is correct...

I think you should need to read the manual book before asking such a basic question like that.

If you can't access the book at home, then get it printer out somewhere.

Bro do u good in PC stuff too?
