Product Details

Dayton Audio PMA250 250W PA Module with Mixer

This amp is ideal for building active monitors or converting existing speakers to a powered audio system. Perfect for karaoke applications! The open frame module design mounts easily to speaker cabinets creating a self contained portable P.A. system. The unit features two microphone and one line level input, each with its own level control allowing for easy mixing of all inputs. Each input is compatible with both balanced and unbalanced sources. A handy line level output allows for easy daisy chaining of multiple amplifier units.

The amp also has a convenient speaker output for connection of an additional "slave", or non-amplified speaker system, so only one amplifier module is needed for a two speaker system. The high performance class AB amplifier has all the power you need and includes thermal, short circuit and fuse protection for years of reliable use. Other useful features include clip indication LED, bass, treble and master volume controls. Includes 1/4" to RCA "Y" adaptor, 8 x 3/4" mounting screws and 6 ft. IEC power cord. 120/220 VAC switchable. Dimensions: plate = 10-7/16" square; cutout 9-1/2" square. 3-3/8" max depth at power transformer, bottom left of plate. S/N Ratio: 73 dB A-Weighted.

Dayton Audio PMA250 250W PA Module with Mixer
Dayton Audio PMA250 250W PA Module with Mixer is rated 4.0571 out of 5 by 35.
Rated 5 out of 5 by from FlexibleI purchased this amp 6+ years ago. I mounted it in a box (NOT with the speaker) and am using it as a PA amp driving a couple of columns I built with six 10" PeyVey Black Widow speakers. With proper eqing I cover an audience of up to 1,200 and run the program for up to 6 hrs. PERFECT sound, as loud as I need it and doesn't even get warm. NICE!

Rated 1 out of 5 by from not workingI purchased this amp in July, and just installed it into a Behringer 2X10" speaker. I was going to use it for Karaoke. It worked for about 10 minutes before I could smell burning and then it died. I will be contacting PE to arrange for its return in the next couple of days.

Rated 4 out of 5 by from Not too bad. So far so good.I installed this in an unused JBL SF-15 and have used it at bout 4 shows so far.It seems to work as advertised.Pros:*Fairly powerful. I have no problem filling small to mid-sized venues.*Installation is straightforward.*Nice to have the built in mixer with mic and line inputs.Cons:*Unless you install it from inside the cabinet you are almost certainly going to damage the knobs at some point- it would be so much better if the mounting plate was recessed.*As mentioned in another review, the line-level input does seem weak. You really have to crank it up to get good sound levels.*Hard to distinguish the level knobs from the bass/treble/etc knobs. They are all the same color and all grouped together.*A bit pricey for what it is considering that you can get an EV powered 12 speaker for about $350.All in all not bad for what you get. If you have an unused full-range cabinet lying around that you're not using (like I did) this gives you a chance to get added life out of it.I have no idea about the long-term reliability of this unit and I'm not sure if I would depend on it as your only powered speaker system but since I do 3-5 shows a week I should find that out fairly soon.

Rated 5 out of 5 by from Good product does the job wellI replaced a built in power amp on a 220 volt German Leslie speaker.this allowed me to have tone controls and a XLR input eliminating a unbalanced converter and a huge ground buzz. this is good amount of power for my application.they are quite and well built. this is my second unit and i would buy more.

Rated 1 out of 5 by from 1 input is very weakThe last input is so weak I had to boost the gain all the way up to get sound from a pretty hot source

Rated 5 out of 5 by from Awesome Amp!I purchased this amp to convert my 3-way 15" DJ speakers into powered PA's. I am using one amp to power both of my speakers. I was a little concerned about the quality and power output, but after a quick 15 minute installation, I am really impressed with this amp. I no longer will need to carry around a separate power amp.The sound quality is great and plenty loud enough. There is no loud pops when turning it on and seems to be built with high quality parts.My only wish is that they would build a 2 channel plate amp with 250 watts or more. This amp will power two speakers but it is a mono amp. So for now I have a mixer converting my 2 channel (Stereo) signals into a mono signal but it hasn't really affected sound quality so I am very happy with my purchase.Mark

Will this fit into the MTX TP1200 ThunderPro2 12" 2-Way PA Loudspeaker? Size? Impedance? Crossover? Drive a slave MTX TP1200 ThunderPro2 12" 2-Way PA Loudspeaker?

Asked by: zooty91
All the specs are on the product page, you will need to scroll down to see them. This is a full range amp so it has no crossover, but this should work for one of those speakers. Since they are 4 ohms, this will only drive one properly.

This amp gets hot. Is there a fan you can buy to install over the fins

Asked by: Dyhomey
We offer quite a few fans that you can use for this but none will have a specific way to mount to the heat sink. A 110 VAC fan will move the most air but be pretty loud, whereas a 12VDC fan will be quieter and most less air, and require a 12 VDC power adapter.

I am building an in home studio setup with 3 speaker setup and wanted to know if I will need a 3-way crossover above and beyond this amp? I want it to sound tip top, so any additional thoughts are welcome...

Asked by: RobIrwin
If you are planning on using this to power a multi-way speaker you will need a crossover between the amp and the drivers since this only has a full range output. For more detailed information, please contact our tech support for more help with this question, or 800-338-0531 x1.

Good afternoon, a have one speaker 8 ohms, and capacity  240watts, so could this amplifier does the job? thank you

Asked by: Laurent
Yes this amplifier will provide 150 watts RMS into an 8 ohm load so it should work well for that application.
