no prblem dude.. whether any one live in anywhere on this earth. technology is very advance now a days.
anyway lemme explain the prblem.
I have a dj music system filled with following.....
2 base with 4x18" boofer
4 top with 8x15" speaker
2 amp ca18 of 5000 watts
1 crossover
1 phonic mx300 mixer
i can connect it all n sound appear very melodious, but there is also so lot more function behind amps. I dnt knw wots is that, how to use them and wots they rule in amps.
if u are intrested then I can post the pics of system.
wots the function of crossover in system. I m nt using it till now.
parellel mode, bridge mode, gain, rms, ohm, db, and many other term is making me irritate.
hey freshie if u knw simething then plz help me.
no any person in my circle is able to help. even I could nt find a paid one.

Crossover used to cut frequency range to the speakers or buffers. Because if you will send audio signal in full frequency range to the buffer (20 - 20000Hz), buffer will give you many bad sounds and efficiency will go done. It means that on your crossover on sub woofer output you must cut all frequency range instead 20-100Hz. And same with another speakers.

Paralleled mode used in amplifier to give possibility to use 2 channels. Means you can connect 2 speakers to 1 amplifier, but nominal output power will decided on 2.
Bridge mode used in amplifier to connect 1 speaker, and in this case i will get full output power.

Gain - is used to up level of sound.
Ohm - is Resistance of speakers, ie you can use 8Ohm speakers with 8Ohm amplifier to get more efficiency. Same with 4Ohm
db - is level of sound.

oh! finally got a ryt person. thanx dude.
tell me, smone who were using my system burn out completly 7 speakers out of 12 in my absense. what could be the strongest reason. coz he is nt telling me properly that what was the scene. n I m also total newbi in this field. burning boofers n speakers hs been happend 2 times n I were nt there. its a total loss fo me. I purchased all them new again and dnt wants get loss again.
u describe well defination. could u tell me how to use these value fo getting top performence from the system. how to maintain connections and settings.
its very time consuming fo u in typing bt hope u will manage to reply.

The best way to setup your system is do it on the place.
But if you will give specs with models or links, some information i can provide.
Because different models - different settings.

ibcrese ni 22g increse hota hai.
thnx fo the info.
@ shpak if I post the pics of crossover n amps from front n back then can u suggest me connections?
specifications me kya kya info du?

I could nt upload pic coz of low network. n I will do it as soon as possible.
now the specs of amps n crossover are.......
crossover- coz I dnt hv too much technical info, I m typing wots written on its front. its a 24 db linkwitz riley crossover with total 7 nobs, cha low, mid, hi. chb low, mid, high + a sub nob. mono is also written in lower place of sub nob. all nob also hv a mute push down butten. in the middle of crossover there is 2 more push down butten with 3 led. mode 1 and mode 2 and 3 way + 2 way + fr is written on these.
in the back side there are 9 option for conection. lemme start in sequence, ( sub) ( hi chb) (m-h/fr--2way) (low). ..... (hi-cha) (m-h/fr--2way) (low) and input is ( chb) (push down butten with mono) ( cha)
soz if it makes u irritate.
amps ki bhi du kya?

Channel A and Channel B inputs - there you connect Left channel and Right channel from your mixer.
For each channel you mast connect speakers:
low - for sub-woofer amp
Hi channel (hi-ch) - hi frequency speakers amp
M channel (m-h/fr--2way) - Middle frequency speakers amp

If you have only woofers and normal speakers, i think you need to use only Low and M channels.
Try this =)

low channel is woofer amplifier - speakers 20-100(200)Hz range
M channel is normal speakers amplifier - speakers 200Hz>more range

Normal 2 way speakers are like this:

It consists of 2 speakers:
On the top is a high freq speaker and on the bottom is a middle freq speaker.

You do not have woofers?
2 speakers or 2 speakers like 1 box? Or 1 box and 3 speakers and 1 connection
If you have in 1 box 3 speakers - there no utilization of your crossover...
Better see photos...I get confused)
