Dayton Audio PMA250 250W PA Module with Mixer
Why not a full range plate amp without a mixer?
I have used these amps in the past and have had good results with them in different projects from small PA full range box to a 4-10 upper mid box for a bass amp. I just wish it didnt have a mixer and maybe more power. Or possibly a bi-amp model to build a cabinet similar to a JBL eon or a Mackie 12" 2 way.Also with my experience with these amps is that they tend to run hot and if you are at an outdoor venue be sure to keep them out of direct sunlight. I have had to use a fan on mine to keep them from shutting down.
There are companies that make plate amps that are full range with no mixer, and variations for bi and tri-amp. They are in the pro league and tend to be VERY expensive. Yes - you are very right - not only is heat and sun bad for the amps - it's hard on the woofers. The frames get very hot conducting to the spiders and surrounds pre-maturely aging them

is there a protective enclosure for circuitry?
Is their any protective inner enclosure or baffle included to protect the circuit boards from damage due to the vibrations of the woofer?
There is no protective cover, but it is well sealed to prevent air leakage. I don't believe that the circuit boards would be subject to vibration damage. I've run them quite a while with a lot of power, no problems.

are speaker crossover units needed in addition to this module mixer plate amplifier
Yes, this unit doesn't feature any kind of internal crossover or bi-amping circuitry, so if you're using various speakers for highs, mids, and lows, you would need a crossover network of some fashion in place.

Will one of these be able to power my idea for a speaker?
I currently have a pair of Technics SB-A53 speakers. I bought them cheaply, and they are plenty loud enough for the parties I DJ at.I'm planning on building a speaker box and just pulling the components out of the Technics Hi-Fi speaker boxes and putting them into a more portable box using this plate amp.The speakers are rated at 250 watts each, and I'm wondering if this plate will work to power 1 of these speakers, maybe even both of them put into the same box.
Short answer is yes this plate amp will work with any speaker between 8 to 4 ohms and provide a good solid 175 Watts RMS to 8ohms. I don't know much about these speakers so i would check to see that the drivers are rated. Are the speaker cabs 4 ohm or 8 ohm? If it's 4 ohms per cab then you will need 2 plate amps.Hope this is of assistance.

Can an acoustic guitar be connected to an input along with a mic?
You can connect two mics to this amp or any mic or line level to it. You didn't say how you are contacting the acoustic and, well. it's called an acoustic guitar for a reason. Some have built in pickups or you would need one or to have it mic'd then run either 1/4" or XLR.

What type of speaker/s wouldyou pair this with?
I sing and accompany myself with an acoustic guitar. Does anyone with decent technical knowledge have any suggestions for a good sounding but relatively budget friendly selection of speaker and or crossover components?
I also perform in small venues an appreciate my small good sounding portable PA system. I think this amp installed into a pair of MTX12" on speaker stands located behind on both sides would be awesome and affordable.
