Ive just bought 2 pevey impulse 1012 speakers that are rated 8 ohms. I want to use them with my alto pbm8 500 powered mixer ( 500w per side) that is rated 4ohms. Will this set up work ok? will it do these speakers justice.

This mixer will run 2 8 ohm cabinets per side, if this is an older unit, it has only one NL2/combo jack per channel....with the button on the front panel in the Main Monitor position you can run 2 main cabinets and 2 monitor cabinets, you will have to daisy chain your speakers.All speakers powered from the back of the unit must be passive, no powered speakers.....if you want to use this head just to run moitors and run a pair of powered mains then connect the jack on the front that says main out to input of your powered speakers, hopefully your powered speakers can be daisy chained at low level, then if you want to use the 8600 to power only monitors, get a 1/4 in y cable and plug it into monitor out on the front of the mixer and then plug it into PA 1 and PA 2 to the right there and both sides will now be the monitor mix from this mixer and it will run 2 speakers per side, as long as the cabinets are 8 ohms.
Those specs would be right - I have this same board but the amp was fried by a previous owner. I pulled the amp board out and tossed it and use the mixer now to drive an external amp. Great board.
This amp is rated at 1200W "peak", bridged into an 8ohm load. That would equate to about 900W RMS bridged into 8ohm or 450 per side into 4ohm loads per side.
You can't daisy chain all 4 speakers....impedance would be too low. You can run two of your 8ohm speakers per side - that results in a 4ohm load per side for the amp. That would give you amp delivery of 450W per side. Your speakers are rated to handle more than that so you're fine.
For the record.....you could run one speaker per side no problem....just lower power output.
Sorry, but you have a problem. The amp is rated to 4 ohms per side. Your speakers would have to be 16 ohm type to allow 3 per side in parallel. The Bose ratings are usually consumer type ratings and they would have to be set to 200 watts each (twice the rating that the amp can produce per side) to be safe connected to that amp. Your speakers are likely 8 ohm so you could parallel ONLY two per side OR if they are 4 ohm, then you would have to series them. You could series two or three per side safely for the amp. You don't tell us what model Bose speakers you have. Anyway, one has to first meet the specs of the amp and the speakers to avoid damage. It is likely the amp is too BIG for the speakers. For the setup of the mixer portion of this problem I want you to view videos on YouTube. Search for "mixer setup". Don't worry that they are different mixers than yours... there is enough commonality and the functions are nearly the same for MOST analog mixers. Recommendation: forget about two of the speakers... keep them as spares and run low volume to avoid blowing the speakers. I can't imagine any competent audio equipment supplier configuring your system this way.
First off it's outputs to your speakers. If you had an extra set of powered or amplified speakers you could "Y" cable your speaker outputs. Your passive speakers won't work without an amp. You really need powered speakers or an amp for your extra speakers. (if you had powered/amp'd speakers you could run them off one of you "aux" out for monitors. Do not daisy chain your speakers connecting twi together, you'll change the resistance/ohms and damage your speakers. Trust me, I do this for a living.
Hello Sir, Hi, the amplifier best suited for it would be a Behringer also, the EP2500 would be a match, and the eurolive B815neo speakers, but this cost a lot, any amplifier and a corresponding speaker will do. for your electric guitars or acoustics the GTX30.
If you will use your 15" speakers, match it with a right amplifier, you did not mention its watts rating, If your speakers are 250 watts, then buy an amplifier slightly higher that 250 watt,
that depends on your speakers, not the mixer. the amp should be matched to the speakers, in watts and in ohmage. for example, 400 watt, 8 ohm speakers should get an amp that runs at 350-500 watts at 8 ohms.
This is hard to explain and what needs to be done is wire in parallel both subwoofers. This website will help just put in the amount of speakers and amount of ohms each and it gives you diagram. http://www.the12volt.com/caraudio/woofer_configurations.asp?Q=2&I=81#results
If the speakers are rated at 500W or greater, then you'll need two amps to get their full potential. When you connect two to a single 500W amp, each speaker only gets a max of 250W. Also, check the ohm rating for the outputs of the amp and the ohm rating of the speakers as well. Unmatches speaker/amp impendence also results in poor performance. If you connect two speakers to one terminal, the total impedence of the speakers falls by 1/2 (two 4 ohm speakers wire together will result in 2 ohm impedence). So, if you have an amp rated at 4 ohms, you could connect two 8 ohm speakers to a single output. Hope this helps some!
If the horn cuts out after some usage ...then its probably the limiter lamp that is gone .... the limiter lamp is switched into circuit once the " polyswitch " gets hot .... so at first the horn works ...then when the limiter lamp is switched in ...nothing !
its just a standard 12volt car tail light lamp ...let me know if this helps

It depends on the impedence of the speakers. Carfull as you could burn up this amp if you exceed the resistance rating on it. Go here on all of the specs of this model of crown amps. http://www.crownaudio.com/amp_htm/xlsspec.htm Good Luck
