congrats, now you just need to change the sub woofer cable to direct solder
if you don't change the sub speaker cable, there will be 'bass lag' mili seconds sound slow reach....

add me in baby.... ATP3 user

At the initial modding stage, I did solder the subwoofer cable onto the pcb directly. However, later on it had broken the fragile soldering pads, so I removed it.



Now I'm trying to figure out drilling holes on the pcb for a cable connector as picture below shows.

Did TS still active? add me in, VS4121. Long user already, not new

hey all, one proud ADA885 user here.

just bought optical to coaxial spdif converter and now i have digital sound from my laptop to ADA885. i used dolby digital live and now i have 6-channel sound, compared to 4 using quad mode, as well as much lower hissing when not using the speakers. im pretty sure it could also be used for PS3 or XBOX360, so can get surround sound instead of stereo through the analog. got it for 15usd incl. shipping so it's pretty worth it for this feature in ADA885.

Yes, I'm still here. Sorry, have been preoccupied with work lately. I've only been glancing through the audiophile section. PM me if I don't add you to the user list.

Why don't you make a breakout board instead of drilling holes on the existing PCB..

Buy those perfboard, those connector should fit nicely on them..

Perboard cost like RM2 per pieces and can be cut/saw easily..

Read / search thru this thread, I snap a photo of the back of the PCB and bm2000 identified the lose solder ( soldah is his "slang" ), I re-flow it ( put more solder and re-melt the existing solder for a complete connection ) and it is working ever since..

It is not that difficult as it sounds but you would need some basic soldering skills and a soldering iron too..

Hey guys, wanna ask something, i got an Altec Lansing ACS 45.1. I wanna buy another 2.1 AL vs 4121 to connect both through splitter to pc...

1. Does the quality will be splitted also? Or it will remain the same?

2. Wanna ask from the experts, compare between both ACS 45.1 and VS 4121, which one better? in terms of bass, or tremble...or clear sound...because i know ACS sound very blur bit...

I can only answer question 1

it will not split the quality in half though. but in terms of volume power, it will reduce slightly

not sure but if both speaker amps differ in power,ohm,current,etc. it might interfere and one will benefit more than the other

Oh, so it means that, the volume power will reduce, so if i turn up the volume bit, still same huh? I thought the bass or sound maybe will reduce to half though it splitted ba thanks dude

i'm no expert =) but i can try to help answer
ACS 45.1 obviously has more nice bass, blur because its old and doesn't have tweeters
has slightly nicer transformer,10000uf powerfilter


VS 4121 has tweeters(clearer) but doesn't sound as good as 45.1 because the new models are all cost cut versions...
has cheaper transformer,4700/6800uf powerfilter

personally i have both, and i still prefer the 45.1 anyday =)

Hmm...i can feel the new version of AL is a bit like cheaper quality if compare to ACS 45.1, coz nowadays all made in china, and ACS 45.1 of mine is made in US...thanks for the info and, did you just open it up?
