AMPLIFIER

Apa yang kau nak ni pun aku tak paham.

5.1 channel pakai delay? Audio ke movie?

Belajar dulu ikut peringkat.

1-Mono
2-Stero
3-Mono surround
4-Stereo+mono surround
5-Stereo+stereo surround
6-Stereo+virtual surround (macam NICAM/Dolby surround/delay line)
7-5.1 (Dolby Digital)
8-THX
9-7.1(DTS?)

Kau dah sampai peringkat mana? Kalau aku baru masuk dalam peringkat THX, itupun tak habis sebab tak mampu.

I think all the DVD player can support it

and so easy to build
from your 2.1 atau 2 chanel audio output

Not all DVD player can support execpt those expensive branded player....

Its not easy for me, coz normal ppl could not build this kind of amplifier, it requires alot of equipment to build it and costly...

[QD_boysJB]

geng
tolong la bantu aku
buatkan atau carikan
delay line yg sesuai...(rear signal)
side signal(stereo)
rear sound (stereo) yang ada sekarang adalah mono-rear-surround sound
centre-rear-sound...
aku harap korang leh bantu aku.....
okkk

Are you sure about it? a 5.1 channel audio input is depending on how can the player support. By the way, can you afford this? We can start from a 2.1 channel computer speaker amplifier, it may be more easy to modified it...

nie cara2 nak buat 5.1ch decoder yg sempurna(complete) tapi untuk peringkat biaser jer la... bukan untuk yg expert... tapi boleh laaaaaa...


nie untuk cadangan camner nak connect semua unit 'surround sound system'


nie dia punya matrix decoder + subwoofer decoder...


nie laks dia punya 'digital delay unit'



nie laks dia punya 'stereo width controller'


nie laks dia punya 'electronic crossover'


nie laks dia punya complete power supply untuk 5.1ch decoder nie....

occay nie sajer yg aku dpt beritahu korang tentang camner nak buat surround system yg complete...
selamat mencuba...........

chowwwwwwwwwww......

Ops.... forgot to tell you guys, that 60V input is power supply input.... not audio input.... sry..

Volt lar.... try check some high class audio amplifier, especially tube AMP, its output is about 300V++...

occay, occay... aku faham...

Input with 60++volts?...R U sure it's volts?..Not watts?

Just Curious...

I think 60 watt la... not volt...

[amirul_km]

 Oh My GOD!! too many channel ler.... I prefer using 2 channel and a transistor AMP. Sound clear much better for me, I like a AMP with 60++ volt input too..

Sound clear, everything is good...

sorry aku tak dt upload gambar amp dia sbb masa aku nak post di tulis...
The upload folder is full. Please try a smaller file and contact the administrator.

[QD_boysJB]

nie aku ada combined-diagram....
try la...
aku pun tak try lagi...
kalau ada saper2 nak buat... jangan lupa buat amp dia sekali.... buat 11watt pun jadi la....
asal boleh...
try to do it...

Me too.... so boring.... but playing with a 5.1 channel Amplifier is not a good idea, its too hard and the circuit is too big. Maybe we can play with chip AMP like TDA2050, LM3886 or TA8229K, only 1 or 2channel... we are still rookie...

I think , the first think we should do is to do the 5.1 surround sound encoder.... after that kita baru buat dia punya amp pulak....
masalah aku sekarang aku nak cari atau korang boleh tolong carikan camner nak buat rear-sound dia stereo... selama nie aku dapat hanya mono.... jadi senang citer kita akan dpt just 4.1 ch.... kalau kiter dpt stereonyer belakang sound (rear stereo) kita boleh combined jadi sampai 6.1 ch... dan kalau korang dapt , atau aku try cari camner nak buat output signal untuk 'stereo-side-signal', kita akan dapat 8.1ch.... lepas tue baru kita buat amp dia laks.... amp kita boleh buat serendah 10watt dah cukup..(bilik punya ) kalau nak buat satu chip yg boleh buat 4ch sekali gus ... kita boleh pakai IC TDA 1554Q....(4X11watt)....jadi kita boleh pakai just 3 IC TDA 1554Q...
argh citer banya pon tak guna...
yg penting sekarang camner nak buat:-
delay line yg sesuai...(rear signal)
side signal(stereo)
rear sound (stereo)
centre-rear-sound...
aku harap korang leh bantu aku.....
okkk

iskhhhhhh
aku tengah bosan nie
jom la borak pasal surround system
saper tahu aper dia dan apa apa la mengenai surround system citer ar..
aku nak tanya sikit
kat pawagam biasanyer diorang guna berapa channel....(maksud aku kalau utk rumah 5.1 atau 7.1 ch... kalau kat wayang laks berpa ch)
camner nak buat surround system yg berbeza (maksud aku speaker belakang)... selama nie aku jumpa kalau utk rear speaker sumernyer samer kiri dan kanan ...... jadi takder beza la untuk rear left dan rear right... jadi camner nak buat supaya speaker rear left dan rear right berbeza signal nyer....
lagi satu camner nak buat DELAY UNIT yg ok... aku dah jumpa... tapi guna IC mitsubishi M65830 ... aku dah try tanyer kat kedai tapi diorang kata takder juall... jadi aku kena pakai IC atau opamp lain.. tapi masalahnyer takder org lain yg pakar tahu buat...
poning aku... jadi siapa yg tahu buat terangkan la...
lagi satu saper yg pandai mengenai teori 5.1 dan 7.1ch... terangkan la... camner nak dapatkan signa utk rear left... rear right.. front left... front right... centre... dan subwoofer....(nie untuk 5.1ch) tapi kalau utk 7.1ch laks apa yg lebih lagi 2 tue...tak paham aku...


apa tujuan width controller...
apa tujuan delay unit yg sebenarnyer .. adakah hanya utk melambatkan bunyi sampai ke telinga kita atau ada tujuan lain...

tolongla hamba tentang audio nie... sesungguhnya hamba tak berapa arif mengenai audio nie... tetapi minat hamba tentang audio nie amat mendalam....

thanks bebanyak my friend

Based on your description/explaination you're looking for 6ch audio, later you asked for LPF schematics. Few years back I work with a lot of audio system wether in setting up or repairing, so I basically know lot about them.

I'm willing to help anybody who want to improve themselves, but, wait you don't even know what NICAM is. And, as previous ocation your answer will be something like this http://www.qd-race.com/forum/index.php?board=16;action=display;threadid=569;start=0#msg7880.

It's my "iman" which being tested here, others I don't know. Good luck to you.

Once you think you really want to improve yourself e-mail me. Else, don't give us your childish request.
