tak berapa clear lagi..
jumlah ohm tu bergantung pada berapa biji speaker ke? atau pun, mmg sebiji speaker ialah 8 ohm?
so kalau cabinet yg ada 4 speaker tu maknanya 8ohm x 4 biji speaker = 32ohm? huhuhuu.. tak tau la bang..

Speaker impedance (ohm) mmg ade tulis kat speaker, beli la speaker ape2 pon, mmg tulis 2 bende; max power (Watt RMS) dgn impedance (ohm). Speaker utk guitar, slalunye comes in 4, 8 & 16 ohm, those r the standard...
There's actually a concept to calculate impedance in speaker cab, which depends on how they r wired. Ade 2 cara; parallel & serial. In parallel the impedance is 1/2 the impedance of the collective impedance. Maknenyer kalo ade 2 8ohm speakers connected in parallel, total impedance dia ialah 4 ohm.
Serial simply means adding the total impedance together. Maknenyer kalo ade 2 8ohm speakers in serial, total impedance dia jd 16ohm...
Cheers...  |

yess faham skrg..
tp kalau parallel, kalau speaker tu 8ohm dan ada 2 speaker, so total ohm dia should be 8 ohm la kan? 4 + 4ohm ...
ok now, aku dah faham pasal ohm pada amp dan cabinet. Here we come to the basic problem.. Now kita ada satu TUBE HEAD 40watt.. so macam mana nak tau head tu mesti connect pada berapa ohm punya cabinet/speaker? kat head tu ada tulis ke mesti load pada beberapa ohm punya speaker..?

Sorry, aku kena rephrase balik ape aku ckp psal parallel wiring, rocket science la katekan... 
In parallel the formula is like this, aku bg example la...
(8ohm)(8ohm)
-----------------
8ohm + 8ohm
Do the calculation on that, & u will get 4ohm total impedance. Lg senang nak kira ialah kalo ade 2 speaker yg same (cth; 8ohm), so divide by two je amount tu, dpt la 4 ohm...
Actually, kat suma amp ade tulis bape ohm yg amp tu blh carry. Kalo ko perasan suma amp ade tulis, check je kat belakang tu, dr yg murah2 sampai la yg mahal giler2, mmg ade. Paling x pon ade dlm manual dia. Amp2 termasuk la jugak amp utk PA system...
Cheers... |

tapi ko kena paham, band aku ni main kat contest, so sound check cuma 5 minit je. apa kejadah yg sempat aku buat dlm masa 5 minit??? setting kat amp je la jawabnya, kalau nak setting kat Zoom, ish banyak patch nak kena setting + save tu bang! banyak masa terbuang, kena potong markah nanti ahahah...

Kalo mcm citer JCM 800 ko td...ko ade Zoom ko, dgn Power Block ni. Kalo JCM 800 ade loop, connect kat return jack, settle. Kalo x de, connect Zoom ko kpd Power Block, speaker output Power Block connect ke speaker cab... |
so maksud ko, Power Block ni sama macam 'single channel clean amp head'.. gitu? correct me if i'm wrong..
thanx bro sbb jawab soalan2 merapu aku.. hehe

Yup, aku paham situation ko, & psal situation mcm tu la gear2 gitar mcm multi f/x kat Msia ni popular giler. Hook kat depan (insert to preamp) lps tu adjust pakai EQ pd amp nak dpt tone. Set sound dr multi f/x ke input amp lg senang drpd masuk ke return jack f/x loop. Unless ko blh jumpe cara yg cepat nak adjust setting, mmg susah la ko nak perform...

Dia single channel, tp gain dia blh push sampai distortion. So far usability amp ni mmg bagus; light weight, good sound & portable. Price pon ok & features pon byk, mmg cool la...
