[QUOTE=Manimal]Is this a line out or a speaker level out?[/QUOTE]It is a speaker out. It is wired in parrallel to the speaker that is already in the cabinet. Do not run it into anything other than an adequate speaker load.

[QUOTE=Samick]i need some general info on vocal P.A. thanx[/QUOTE]

well, that is TOO general.

what do you want to know?

My PA's speakers are 8 ohm. If I added on an 8 ohm extension speaker off of each end would that bring the load down to 4 ohms? I'm not sure if my powered mixer can handle 4ohms or not.

2 8ohm speakers wired in parallel will give you 4 ohms.

It will also depend on the outputs of your powered mixer. If it is a stereo powered mixer then yes you should be able to do this. Having a minimum of 4 ohms load on each of the two outputs.

However, if it is only a mono powered mixer, and if you are currently running two 8 ohm speakers off it then it will already be running at 4 ohms.

I just double checked. Its a mono amplifier. Meaning my 2 8 ohm speakers are a 4 ohm load on the amp. Meaning that adding on 2 more 8 ohm speakers would create a 2 ohm load correct?

Yes, correct. And it may not be safe to run anything < 4 ohms off your powered mixer.

I always see amplifiers in musicians friend being advertised as 1000 watts x 2 @ 2 ohms and such. Is this just false advertising to get you to think "more watts, better amp"?

Can some amps actually run at 2 ohms safetly for long periods of time at loud volumes?

Some amps can be safely run at 2 ohms. Usually these amps have got built in cooling fans and large heat sinks to help dissipate the heat caused by doing so.

It would be best to stick with what is noted on your amp to be its minimum safe loading.

Another question:

My current powered mixer is, as you now know, a mono amplifier. It has a line out on the back to connect to an outboard amp. I plan on using this later on to run either monitors or my mains if i need more power later and run my monitors off of the powered mixers main outs. If i use a stereo amp for this will i need to run a splitter cable to duplicate the channel onto the second stereo channel of the new amp?

This powered mixer has a cooling fan in the back. I'm not so sure as to if it can handle that type of load though. I'll have to check in the manual.

[QUOTE=Manimal]Another question:[/QUOTE]
A Y splitter would do the job.

Good stuff.

Thanks moaner and Aes.

Looks like I have another for you guys:

I tried plugging my guitar direct to the powered mixer to see how it would sound. However I noticed that the level was very low even when the volume on the channel and the main volume was set very high? Is this normal or is something wrong with this?

check for a mic gain knob?

If you are running an electric guitar direct you'll need either a Preamp or a DI box before running it into the powered mixer.
If you are using an acoustic/electric guitar (with a built in preamp) then make sure the levels on the guitars preamp are suitable set and it has fresh batteries in it.

Just a footnote tho. Running an electric guitar direct to the PA (using a DI) doesnt usually sound too impressive (especially not if you want a distorted tone - It wont be any good for the Mixer anyway).
I'd reccomend using an amp modeller (like a POD) or a Preamp with a suitably voiced direct output. Better yet, Mic up your guitar amps speaker cabinet.

behringer make a DI box with cab simulation, for not a lot of money. You could use that with a distortion pedal or amp's line out.

Yeah I know it doesnt sound very good. I was just curious to see how well it actually sounded. I'd never think about doing this to use as an amp.

[QUOTE=moaner]well, that is TOO general.

what do you want to know?[/QUOTE]
just simple things like, do u plug the mic straight into the p.a. whats a cheap one, why do i gotta use a p.a. on vocals VS a amp.
never used p.a. befor so...

There's really too much to go into.
I suggest you read through these articles: [url]http://www.colomar.com/Shavano/pa_page.html[/url]

Then ask more specific questions if you need anything confirmed.

The built in effects on my PA just don't work, it dosen't say anything about it in the instruction manuel

Here it is:

i need moniters, i figure this thread's close enough. I don't have much money at all to mess around with, but i want 2 moniters, i dont need them to be particularly loud. I already have a mixer. any suggestions on cheap moniters?

Are the FX send levels on each channel up enough?
Are the FX return levels set properly.

monitors? cheap?

not usually words in the same sentence.

the problem comes when you need a way to power your monitors.

Either, get a powered monitor, and a passive, and use those (works out expeensive)

or a couple of cheap passives off ebay, and a cheap poweramp (a bit cheaper)

better still, find a band upgrading their PA, or buy a new, small Pa setup. then, use the speakers in it as your monitors, powered by the powered mixer.

argh... so even if i buy PAs i still have to use a poweramp? blowage! well thanks moaner, you kick ***. any suggestions on brands?

hmm...

kustom, behringer, and any ebay nonames.

Some model powered mixers come with an ability to be switched to split for both monitoring and FOH applications.

[QUOTE=Aes820]Some model powered mixers come with an ability to be switched to split for both monitoring and FOH applications.[/QUOTE]

its usually not the lower end ones, unfortunately.

I never worked out how they managed that, form an electroics point of view. i guess splitting the line signal into 4 and combining it again after 4 transistors could allow 1/2 ttrassistors outputs to be split for monitoring and the rest combined to make i louder.

Foh?
