A higher watt power amp or a power conditioner.
An EQ could help too.

Run 'er through a brush shredder! ...
:twisted:

then get a new one. :D

hmm, one thing you can try is paying attention to what the speakers are in front of and how far away. you would be surpised how much diff placement against a wall or other barrier will make. You can boost the front end with more vol (eq) but that is likely to ruin your amp. Add more speakers (careful to get the impedance right)

good luck

Turn all the dials & sliders all the way up, and then put your mic right up against the speaker. You'll get a slightly different sound, but it will be loud.

The three things that come to mind are moving the main speakers as far in front of the mic's as possible, keeping the monitors lower and using a feedback exterminator, of course there are many other things that can be done however those three simple things will help without you breaking the bank.

"Keep in mind that increasing output by 3dB creates a perceived doubling in volume."

**Actually Sean a perceived doubling in volume is achieved by a 10 db increase which is achieved by a 10 fold increase in applied power, for example -the difference between 100 and 200 watts is a 3 db difference, this is the point at which someone notices a slight volume increase.



"What all that means is that good speakers can produce more than twice the loudness of crappy ones"

**Since a 10 db difference equates to twice the loudness you'd have to have about a 13 db difference in speakers to say one is more then twice as loud


"depending on the situation and specs you have to play with. If your speakers have a low sensitivity rating, of 91dB, buying speakers with 98dB rating will make your perceived volume double not once, but twice!"

**The 7 db increase is noticable but is not enough increase to achieve double the apparent volume, you'd have to add another 3 db to achieve that...every 3 db increase is achieved by doubling power ; 100 watts doubled to 200 watts will only give you a 3 db increase which is barely noticable however a 10 db increase (equivalent to a 10 fold increase in power) will achieve a doubling of volume (basically going from 100 to 1000 watts)


"In other words, is you have been using speakers rated for 8ohms and 400 watts with a sensitivity rating of 91....and your amp will put out higher wattage at 4ohms....and you switch to 4ohm speaker cabs with a sensitivity of 101dB, you may be shocked to discover your volume levels have doubled three times".

**This sounds like a 13 db difference (3 db difference between 4 & 8 ohm speakers plus the 10 db you mention) this would be slightly more then double the volume.
A 10 fold increase in db level will yield a doubling of volume, to achieve a 'three times' doubling would require an immense jump in power or speaker sensitivity. To double the volume level at 100 watts you need 1000 watts, to double that you need 10,000 watts.


"Just remember that a 3db increase represents a perceived doubling of volume".

**A 3 db increase represents a doubling of power not volume

I'll never forget the day when I was playing barefoot on a cement basement floor. I was using a non-polarized amp, and one of my guitar strings touched a water pipe . . .


LOL...I was grinning by the time I hit the barefoot on a cement floor part. Years ago I got so sick of being shocked half the time when my lips touched a mic I started using a foam windscreen on it. We'd spend 20 minutes trying to flip ground reverse switches and flip plugs over and still have problems, (very few 3 pin ground plugs on older amps) and I finally got fed up and got a windscreen...and avoided playing outside in really cloudy weather...

Now everything I have is grounded, first thing I do is replace plugs with broken ground pins, but I still use my old faithful windscreen, I don't want to know if it's going to shock me, when that bunch of electrons hits your lips it HURTS...and I don't get moustache hairs pulled out any more either :D

But to get back on topic it sounds like some 4 ohm speakers might make a big difference, you'd be surprised how much better efficiency makes too.
As far as grounding problems, here's a cool trick I figured out all by myself after having holes burned through my lips (well, almost). If your amp has any extra 1/4 inch jacks that you don't ever use (fx send/return etc.) plug a cable (instr. or spkr doesn't matter) into it and into an unused 1/4 in jack on the PA. This grounds the two even if you're plugged into completely different circuits. I hate the smell of ozone coming off my moustache.

Keep in mind that better mics will feedback less.
