Hi Kawan2...
Mari kita berdiskusi tentang amplifier...
Diminta para forumer untuk memberi pendapat dan berkongsi pengetahuan... kalau ada yang salah tolong betulkan.. TQ

Seperti yang kita sedia maklum... amplifier adalah sangat penting kepada setiap pemuzik. Tetapi ramai yang tidak ambil peduli dan lebih pentingkan instrument dan efek semata2...

Memang sudah ada beberapa perbincangan tentang amplifier sebelum ini... tapi perbincangan ini adalah lebih kepada untuk mengenal amp dan cara mengendalikannya.
Jadi Eniqma.. Sila jalankan tugas korek mengorek anda...

Mengikut daripada permerhatian.. ramai pemuzik jarang ambil peduli tentang peranan Amp dengan lebih terperinci. mereka lebih gemar membeli, pulas2, main, tak sedap, jual... dan keluar statement AmpA tak sedap, AmpB sedap.
Setiap kali ke studio, berbagai kerenah amp dapat dilihat. Sound yang tidak sekata, bising, humming, cracking dan lain-lain. Tanpa pengendalian yang betul, ia bukan sahaja dapat memberi masalah kepada sesi jamming anda, malah kepada pengendali2 studio yang hensem. Cool

Gambaran yang selalunya kita anggapkan adalah begini:
Gitar -> Efek -> Amp&Speaker -> telinga


Amplifier selalunya terbahagi kepada beberapa bahagian utama...
1. PreAmp - Memproses bunyi dari input
2. PowerAmp - Menjana bunyi dari PreAmp terus ke speaker
3. Speaker


ataupun
input -> preAmp -> Send/Return -> PowerAmp -> Speaker Out -> Speaker

PreAmp pula terbahagi kepada
1. OD/Dist/Clean channel
2. Equalizer
3. misc (efx, boost, reverb, etc)


jadi.. contoh chain sebuah amp ialah:-
input -> OD/Dist/Clean Channel -> Equalizer -> Effect -> Send/Return -> PowerAmp -> Speaker Out -> Speaker

jadi... Amplifier bukanlah sejenis benda mudah yang sekadar memproses input dan menjana output begitu sahaja.
Tapi ia melalui beberapa bahagian seksyen yang setiap satu penting untuk membentuk tone dan bunyi yang keluar. Jika salah satu section ini di setup secara salah, ia boleh memberi bunyi bising dan bunyi yang tidak kita gemarkan.

bersambung....

Kepada yang membaca, mohon maaf kiranya penulisan ini tak begitu teknikal, tak ada tone MOJOs, takde superduper technical term..
sebab aku tak pandai.. ahaha... yang mana salah tolong betulkan

Part II

Dibawah ini dipaparkan gambarajah yang dicilok dari gmarts.org .



ia adalah contoh susunan satu rig.
guitar > efx/preamp > Amp > Speaker

jika anda telah mempunyai digital effect simulator seperti Multiefects... anda boleh menggantikan pedal efek anda dengannya. Tetapi jika multieffect/effect processor anda mempunyai preamp simulator...
seeloknya anda sambungkan terus ke poweramp menggunakan 'Return' efx loop pada amp.

Guitar -> Mfx(effect>preAmpSimulator) -> amp'Return' -> PowerAmp -> Speaker

Tetapi anda juga boleh sambungkan multieffect anda terus ke amp input untuk mendapatkan sound yang berbeza mengikut citarasa anda...
contoh..

guitar -> Mfx(effect>preAmpSimulator) -> Preamp -> Poweramp -> Speaker

dengan ini anda mempunyai 2 preamp...
keadaan ini juga dapat dibandingkan dengan situasi anda menggunakan 2x pedal OD/Dist dalam rantai efek tanpa on/off atau bypass...

Disini dapat kita lihat bahawa adalah lebih baik untuk mengetahui dan memfokus kepada pengedalian preamp (dan effect2 lain) kerana ianya sangat penting dalam pembentukan bunyi yang dikehendaki.
Poweramp dan speaker juga penting tetapi ia memerlukan kos yang lebih tinggi jika hendak menguasai peringkat ini.

bersambung....

pernah baca dulu2.. pasal band Garbage.. diorang langsung tak pakai amp atas stage, semua electronic instrument line out direct to PA, then dengar thru monitors.. diorang kata sound onstage sangat2 la clean, dan tak bising sangat.. tapi equipments diorang warrant this kind of setup la... dengan expertise sound engineers diorang lagi..

my 2 cents:
GENERALLY.. selalunya amplifier senang difahami dengan general electronics architectural design dia.. ada selalunya 2-3 segments.. preamp, power amp, dan tone stack (eq, effects reverb etc...)

preamp : yang ada gain or volume channel
poweramp, yang ada master volume , presence
tone stack (eq) : yang ada bass, mid, treble,

pastu variations of these kind of circuit designs yang buat kita pening.. ada yang hybrid, apa mende itu effects loop, etc...

Direct PA:
Mereka still gunakan Preamp (pedals, efx, mixer preamp etc)...
dan menggunakan power amp dari PA...
Cuma dengan cara ini mereka sudah bypass amp dan speaker miking

Effect Loop / SendReturn:
Selalu nya mempunyai 2 connection out dan in...

Out/Send: connection out dari preamp... Kiranya kita mahu menggunakan sound dari preamp sahaja...

In/Return: Connection in ke Power amp.. sekiranya kita tidak mahu menggunakan preamp amp tersebut...

Jadi send-return atau effects loop juga boleh digunakan untuk menambahkan effect kepada amp selepas preamp dan sebelum power amp... seperti EQ, Delay, OD, etc...
ia juga digunakan untuk membantu mengawal output signal yang dihantar ke poweramp...
Kadang kala signal yang dihantar ke poweramp terlalu tinggi dan mem'boost' poweramp sehingga clipping ketahap OD/Dist...
