PA Speakers matter for sound quality too.
Thanks guys for helping me out. I have a pair of no-brandname PA speakers and am planning to use the for karaoke. Each speaker is rated at 250W and max @ 500W. The speakers require an amp that can pump out at least 200W of power. So the Behringer A500 won't be enough. I'm choosing between the Behringer EP1500 and the Cerwin Vega CV900. Which one of these would you recommend? How good are Cerwin Vega amps?
Your no name brand PA speakers might be a problem, there is so many " No Name Brand Speakers " out there made in China by the lowest Contractor Bid, just like here in America, doesn't that make you feel all warm and cozy inside ?!
It can spell Doom for your Good Sound you obviously want !
Most No Name stuff has power ratings that are outrageous like 1,000 watts power handling and 120 db signal to noise ratio, do not believe it for Once in your life', unless of course it is a reputable brand name, but even then be careful' why ?.........
Ok so here is why:
The 1st weak link in your chain of good audio quality is really your equipment you use plain and simple: meaning bad A/C Line Power and or Line Noise and Grounding Problems like Hum Noise, your Mixer, the Mixer Source, Audio and Speaker cables, CD player, Record Player, Tape deck, MP3's and Loss of Quality Compressed Audio, E.Q unit etc.
Well your speakers are really the 2nd weak link here, and not really your amplifier.
Because if they, your PA speakers sound bad, then no good amplifier or audio source is going to make them sound any better !!!
And so your 3rd weak link naturally in your audio chain is your Power Amplifier.
Don't get me wrong here, their All Important Together here in making good audio sound quality, but what Sound Quality are You looking for, also in your Budget range/cost, so that is really the question here ?
Power amps have to be beefy enough to not clip when the music volume level demands it, a high dynamic power amp will make even cheapo' low wattage speakers last longer because they do not clip as easily. When you do clip an amplifier it is not pretty, and can ruin your speakers' voice coils, burn and scorch them to Toast !!!
Most PA name brand Power Amps are good enough to power large PA Speakers with large Sub Woofers in them, so I think the amplifier will not be a problem as long as you have a true 200 watt rating with a good dynamic headroom response of at least 20 db. And a distortion level of at least .07 at 1 khz. And look for PA Amplifiers that weigh allot more, because of their huge transformer(s) and Huge Power Capacitors inside that translates the 115 volt or 220 volts into a massive power output when the music demands it. Also look for at least a clean Dynamic Power output up to 500 watts Dynamic Level, that should be good for anyone with a stereo PA and Sub set up, and for up to 4 or 5 PA speakers total.
This a ball park and not exact, it really depends on the load of the speakers and that determines the power output and in the speaker Ohms load power handling rating you need in the amplifier.
If you have more PA speakers than say 5 total including your Sub, then you may need multiple amps or a PA amp that can handle multiple speaker channels and more than one Sub.
As the comments already suggested go with more reputable brand names, although I am not familiar with Technical Pro or Pyle Amps, Pyle did make some descent raw speaker drivers like Sub Woofers for car and home speakers at one time.
And I thought they sounded pretty good, but the Name Brand stuff coming out of China now is made better and sounds better than most of the Pyle stuff.
