you wanna plug in an electric guitar and a bass guitar to the amp?

i rather u not. the bass would blow or crack the speakers dude.

somore u wanna use it for church environment?

i agree. actually i think i spoilt my dads guitar amp coz i played my bass thru it. when u crank up the volume, the speakers cant really handle the low freqs and may result in it cracking. i guess mine is spoilt, but i havent told my dad yet hoping he wont find out

anyway, about your k/b amp handling bass guitars, i'm not sure about it but i guess to some extent it is true.
but my question is, you are gonna use the amps to fill up the room for about 50-60 ppl?
i dont think its a good idea. cant u mix it to the main systems?
if u use the amp to power the whole room, u'll be loud in the front (and for you) while soft behind.

my recommendation is just to line in the bass to the main systems. then get a budget amp for your electric guitars. maybe 40watts? just to hear yourself, and mike up that guitar amp for the front of house.

about the k/b's that may be true. but better safe than sorry. maybe the better k/b amps can handle bass freqs but then the budget models may not handle it so well.

u got spare wan, u can plug in the bass thru a DI box mah.
u can try using the k/b amp, but go safe and dont blast it.

well as i said above, u can do anything wan. whether its practical is another matter.
u put 50watts, the front guy can hear loud loud, behind maybe soft soft.
u want behind to hear u crank it up, the front guy + stage goes deaf

u the sound guy ah? where your church again?

that was my suggestion. but his mixer only 5 channels, and 4 are taken up by mics already.

u have to remember that amps are for the player only. not for the front of house / main hall.

DI box is to balance the signal. a balanced signal can travel further without losing the strength of the signal. this helps if your PA is located far from the stage. sometimes the lineout is not a balanced signal, and that is when u need a DI box to balance the signal.

line out from the amp and DI box is usually the same. if they say its a balanced signal out from the amp, then it should be a balanced signal already coming out from it.

if u use the DI, then i guess u can use the last channel on the mixer. but i guess u have to plan out the future needs of the church. better to spend a little now and have room for expansion later.

cheap DI box is by behringer. they are quite good performing budget DI's.

actually, the only reason i asked u to DI box and send to the mixer is so that u dont have to use an amp. if u wanna use the k/b amp, then that will be the monitor for the bassist. then when u output from the amp to the mains, that is for the whole place.

if the output is balanced, then good. u dont need a DI box. but if its unbalanced, then u may have a problem with the signal if the mixer is too far behind.

its safer/better to use a DI box, but it is not a must.

how did u blast it? usually amps wont die unless the signal is distorted (i think) or they handle too low frequencies that they not designed to handle.

i believe yes ler. u try softly first just to be safe.

it wont kill the PA. make sure that the gain settings on the mixer is at the appropriate level, and everything will be fine.
mic the amp or lineout the amp?

hmm thats weird. maybe power spike or something. should be nothing wrong if normally loh.

DI box well anywhere also can get ler. u're from subang jaya? where's your church?
the distributor of behringer in malaysia is Avem electronics. u call them.
should be around rm200 only.

alright. if u wanna come my church to look around, no problem okay.

every last week of the month we try to have jam sessions. u can come n join in or watch if u're interested

hope the setup works for your church dude.

definately, coz the keyboard amp is not really suited to handle the booming bass sounds of the bass guitar.
maybe some low-end from a keyboard, but not full flat low ends.
