good day peeps,

karon lang ko naka remember nga naa koy question that i've asked many people with dugay na unya wala judkoy nadawat nga answer nga claro.

i own an altec lansing 251
its a 5.1 speaker system. when i bought it, it was 5.5k and there was an option to add 3k and get a dolby digital decoder, but wala rako nikuha sa dolby digital decoder ky kulang ako budget para ana at that time.

but i was always curious... unsa gud gamit anang dolby digital decoder? and if ever ganahan ko mupalit ana, available pa kaha ni? is the decoder specific jud per model of speakers?
