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 4.125 out of 5 by 32.
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

Rated 5 out of 5 by from Amazing ValueHats off to the designers at Dayton Audio: This module is fantastic. I installed the PMA250 into an old Klipsch pro audio cabinet with about one hour measuring, sawing. and drilling. Plugged it in and it worked like a charm. The module seems very solidly build. The two mic inputs and one line input give a lot of flexibility. Paired with my cabinet, this amp plays LOUD. The package even included an RCA to 1/4" adapter to simplify plugging in an mp3 player.

Rated 4 out of 5 by from Does what I need it toI bought a pair of these to get away from always having to lug in my amp rack and play some smaller venues without taking up so much real estate in the room. Compared to my triamped three-way system, it comes up short (go figure). However, when I mounted these amps in the back of some 15" two-way cabinets, the ability to play a small room improved immensely. They have more than enough power to fill a smaller room, and the built-in mixer is a really nice feature. I won't use the microphone inputs (I still use my main playback rack with the Rane MP44 in it to drive them) but knowing I could is nice. I've just bought another pair of these, and we'll see how they work with a 4 ohm woofer (I got some Peavey Black Widow 15" rated at 4 on accident) as I've seen some other reviews complain they don't like the lower impedance. However, running them at 8 ohms, with a crossover in the cabinet was like a dream come true. No running tons of speaker wire (just a simple microphone cable) and the ability to chain them together also is a plus for me. The only issue I've had is with one of the inputs cutting in and out, so I have to make sure the microphone cable is supported somehow. I use the velcro strap used to bundle it together and keep it neat in the truck and use that to "tack" it to the back of the speaker cabinet. I would also recommend getting something like a dbx driverack px to help, as having the speaker management capabilities will help them really reach their full potential. Overall, I'd say they do exactly what I bought them for: to add power to some cabinets and make me more portable and flexible in my ability to play more venues.

Rated 3 out of 5 by from fills a need for such an itemI wish I would've known about this type of amplifiers years ago. I build my own speaker cabinets and this gives me the option of making them powered. The only negative thing I have to say is that parts express does not repair damaged units. I can't find an authorize repair center to have it repaired. While inserting into the cabinet a capacitor was ripped off the circuit board.

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.
Asked by: muzeeshun
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?
Asked by: RTS Audio
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

Asked by: c'mon
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.
Asked by: FreakinScreamer
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?

Asked by: Biscuit
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?
Asked by: fossilmusic
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.
