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 4.0294 out of 5 by 34.
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.

Rated 4 out of 5 by from Great standard ampI'm an engineer that designs analog/digital test systems. I build powered audiophile speakers and I'm not using this product as intended. I active filter and equalize three-way speakers, and used this amp to drive the woofers. The power, distortion and features are all in spec and work great. Only two complaints: there is no relay to connect the speakers, so there is an occasional "whoosh" when turned on, and there is a little higher noise (hiss) than I would of liked. But these are expected from PA type amps. I have four, and in one, an internal cable was reversed on assembly (which reversed ground and shield with no affect) - made in China.

Rated 4 out of 5 by from more power!works as advertised. converted a 2-12" cab running at 4 ohm to use as side fill. Its the only plate amp that i've found so its hard to compare with any other product. I wish it came in a more powerful version. Also the knobs are unprotected, so install from the inside of the cutout so the knobs are recessed, this offers some protection. good product

Rated 4 out of 5 by from If McGiver was a DJ........he would have one of these.I just comnpleted the install of my PMA250 onto the back of a Kustom KMC12, and I cannot express how proud I am for making the jump from Passive speaker to Active Speaker.For years I have been a skeptic of powered speakers, but with my having a huge Wedding coming up to be held on a little Island destination known as Catalina (of the California Coast), I had no choice but to experiment and see how compact of a mobile system I could make with the tools/speakers I had on hand.I discovered the PMA250's while on browsing the Web looking for a Powered Speaker to buy for an upcoming Wedding in which I will have to take a Yatch Crusie Boat in order to reach my destination. Anticipating luggage and equipment weight restriction I knew having a Powered Speaker System would drastically cut down on my weight and the amount of Anvil Cases I would need to carry since my main DJ Coffin was going to be too heavy.However, the cheapest active speaker I could find with any quality started at $399. By opting for and mounting the PMA250 on the back of my Kustoms, I am not only saved money, I also saved lots of space, and weight.Other reviews that I have read on here have mentioned some hint of noise. Well I suspect that was all apart of their own electrical home wiring. When I fired up my PMA250, the sound quality was EXCELLENT. If not for the green indicator light on the back panel itself, I would not even have known they were on.These speakers are quite when at rest, and produce excellent volume when at play. Perhaps I did a great job of matching the right speakers. No his and no dostortion (even at 80% volume).I have yet to actually use these on the road, but a mild home test proved to be satisfactory.For good measure, and not one to take chanced I took the initiative to instala dedicated 1/4 jack on the existing panel and ran the amplifier to it, instead of directly to the speaker. By rigging my speaker to be used with a 1/4" to 1/4" jump jack, I have left myself a way out, and can always unplug the PMA250, and run my primary Amplifier into the passive jack inlet, should I ever have any problems with the PMA250 cracking up under pressure.I am so pleasedd with my Daton so far, I have already begun scoping out other Dayton Brands here on Parts Express. I have never heard of them before shopping at Parts Express, but it appears they may be Parts Express' exclusive Brand.....so far so good.Many thanks to PE.Kurt / DJ 'K' the #1 D.J. in the USA

Rated 5 out of 5 by from Excellent Plate AmpI used this amp for a mid-high box for a keyboard setup. I use an active Carvin box with a 12 and a horn, but like most setups it a great PA unit, but lacks a strong mid range for keyboards. I built a box just big enough to house an 8" NEO speaker, a horn, driver, this plate amp and a customized x-over. It sits atop the 12" active box.It's become a lightweight very efficient mid-range active speaker. The pianos and clavs cut through the mix with incredible clarity.I recommend this amp for doing DIY portable amplification.

Rated 4 out of 5 by from Great value of a hard to find productIt's clearly made in China but for the price it is a great product. I've run it hard for several hours and no issue with overheating. So far, it's been able to handle the road but I have some concerns about how it will hold up under the abuse of being on the road. I'm very happy with the performance except that it DOES NOT soft clip and will distort during clipping. Would have been nice to add an output limiter. All in all, I'm very happy.

Rated 5 out of 5 by from A Good ProductI bought two of these PA modules to install intwo of my home built stage monitors to reduce theamount of equipment I have to haul to smallvenues. I had designed the monitor cabinets sothe backs were big enough to mount these modules.Initially, I had some concern about heat build-upin the monitiors because they are filled withpolyfil for damping. It does not seem to be aproblem because the amps seem to run faily cool.These amps provide plenty power for the 12-inchwoofers in the monitors which are rated at 175 WRMS and have a SPL sensitivity of 97 dB re 1 Watt.Another good thing is they don't seem to be affected by having the speaker disconnected duringuse. I tried it, expecting the fuse to blow orsomething. When I reconnected the speaker and theamp was still going. Very reassuring.My only real concern is that the level and tone controls may get damaged because they are not recessed in the panel. I am considering addingsome sort of cover to protect them. I alsonoticed that these amps do output some quiesentnoise, but it is very low and quite acceptablefor their intended use.All in all these amplifier modules seem to be agood product and fill a real need. I intend topurchase several more to install in the othertwo stage monitors I have. I am very pleased with these amplifiers.

Rated 5 out of 5 by from heavy-duty & well builtI bought this amp to power an 8 ohm 12" Pyle Pro PPA-12 woofer in a small 2 cubic foot enclosure I built for my bass guitar. No whistles and bells, but once I got the port tuned correctly, the whole system really sounds good! Very tight, solid deep bass with clear sound... no distortion and plenty of volume for small gigs.I messed up by buying a 4" Precision Flared Port Tube for this small of a cabinet and couldn't get the bass to sound quite right. I resorted to my old tried-and-true method of using 3" ABS plastic pipe for the port... getting the length close by calculation... and then fine-tuning by cutting several lengths in 1/4" increments a little shorter and longer than the the prescribed length. After playing a bunch of music with different kinds of bass, one length definitely stood out as performing best overall. It wasn't scientific, but it works well! Total cost of project was under $200... and it definitely sounds loads better than other small bass head-speaker combo's I've heard for anywhere near the price.

Rated 5 out of 5 by from Solid PerformerThey get the job done as adverised. They Don't get too hot which is encouraging, and i am driving a 4 ohm load (crossing over above ~150 Hz) I haven't found many other options, but would buy again for this application. I don't really need the mic pre's since I use 2 of these in a stereo keyboard/instrument rig for a rock band over the last several months. In fact all the bass, guitars and keyboards are coming through it now. The only second thoughts I have is that buying 2 was about the same total price and weight as the entry level QSC GX amp (which I use on the subs). So my speakers are heavier than if i had designed the system with another power amp in a rack w/wheels. But if you need a powered speaker this is a good way to go (I don't know why major power amp companies don't have anything like this)

Rated 4 out of 5 by from Got my PA back up adn running with this one!I bought this amp module to replace a similar one sold under another brand label which got damaged at a gig. I'm pretty sure the Dayton module is an updated version of the OEM panel I had been using - about the only difference is the use of combi-jacks instead of separate XLR and 1/4" jacks, as well as a larger heat sink. I had to cut and fit a new back panel to the speaker cabinet as the Dayton panel is slightly shorter than my old one, but that was relatively easy. Once installed, the speaker tested out just fine! I think after an initial break-in period this amp panel will perform well. I'm planning to use it at rehearsals for a while before bringing it out to a show, just un case, but I'm not expecting an issue. By the way, PE ROCKED the shipping on this order! I placed my online order at 2pm on a Thursday and received the delivery at 4:30pm on the Friday! 26 hours from order to delivery! To Canada! Nice job, PE!

Rated 5 out of 5 by from Worth checking intoI have been useing these for a couple of years, in my monitors. Rescently I started using them in a small set of Mains ( front of house ). I use them for everything from the Band to DJ! If you have a good set of speakers and want to be able to leave the heavy power amps at home? This is the way to go. 250 watts at 4ohms is a lot louder than you may think. Check them out you wont be disappointed.I've played in Country Bands for years, and have small home studio, and I love them enough to own 5 Sets

Looks like they took care of the seal problem other people were complaining about because nothings leaking. Using it as an active main for the smaller, acoustic shows and what not that i do instead of dragging along my QSC 1450's. I strongly suggest that if your looking for something like this, this is it.

Rated 4 out of 5 by from Great addition for roadworthy keyboardUpgraded my computer based Hammond organ clone rig speaker cabs with 2 of these amps. Also upgraded with PE's 260-140 crossovers and 264-225 compression drivers. Plenty of power even at 8 ohms. Could not get a schematic, but figured out a mod to change one of the mic inputs to another line-in via the preamp feedback resistors. Cabs + amps a little on the heavy side but system works well. Amp heatsinks are just pleasantly warm even after a pounding outdoor gig. I've had a number of orders with PE over the last 3 years and I'm happy with their products/service/shipping. PE, keep it up!

Rated 4 out of 5 by from Great way to make a powered speakerHave had 3 of these:2 have been built into old RAMSA Speakers WS-A200 to be exact on a rebuild project - They sound amasing so good I bought another!With 1 speaker and a passisve WS-A200 you can do karaoke or DJ a cruise ship for about 50- 100 people!Has enough power to run in stereo ( 2 powered speakers) and drive another pair - I've been pretty impressed as this project was simply to be used as a back up speaker or monitor for larger shows!Only a few caviates:1. inputs and outputs are not fully sealed and will leak air - not a deal killer but if you cover and seal the ports yourself this unit rocks!2. Watch your levels - this amp will clip (like ever other amp in the world) and gets very hot and as it gets hot will sound terrible.That said, buy a compressor if you are running a mixer into it and you will be fine otherwise just watch your levels!~over all this was a great value when it was a no name plate amp as well as when it was made by dayton- I said I had 3 - 1 is about 4 years old and still great - the other doa out of box but... I didn't find out till about 9 mos later when they became Dayton - Parts express honored the warranty and I got the new dayton which is identical to the first 2.Thank you dayton and Partsexpress!!!

Rated 2 out of 5 by from Poor Speaker Protection (if any)When the amp worked it was a great little system. However, I was playing Christmas carols through the PA last week when the amp fried and took out the woofers in each cabinet. This amp's specs say that it has speaker protection circuitry but it my case it didn't have any protection; both woofers are burned out. The company has said it will replace the amp, but not the speakers.

Rated 5 out of 5 by from Neat Product!I installed this in a well used speaker that was given to me. The result is wonderful! I tried it with a SM57 mike and it makes a pretty good Karioke.

Rated 4 out of 5 by from Great little ampI bought one of these amps to convert an existing set of PA cabinets into a powered set of boxes that anybody could figure out how to use; and it works perfectly. Each cabinet has a 12 inch Selenium woofer, a six inch Celestian sealed midrange and a Motorola Piezo tweeter. The sound is awesome, with excellent sparkling highs and plenty of punch at the bottom end. Have used this set up for church picnics, beer gardens, announcing players at baseball games, bingos and backyard parties. Nice and portable and so far no problems.

Rated 4 out of 5 by from Turn any speaker in to a powered speaker w. MixerI love that it has line and Mic inputs as well as speaker out and line out. I wish it was a bit lighter and could take RCA inputs, but it comes with an adaptor to do just that. this is the 3rd one I have bought of the the first two I bought died after 2 years of use. I could be louder as well the line level input is a little weak.

Rated 4 out of 5 by from Zero ProblemsI've built 3 monitors with these with no problems. We run these 'bout once/wk. I was skeptical at first, but after surviving outdoor heat, late night humidity, & careless connections during setup, we're pretty impressed. They deliver good punch & clarity for monitor use & run fairly cool. Of the 3, one was odd in that it shipped with different feeling pots.observations: 1. they do "leak" air at the connections2. Wish they were flanged for recess mounting3. mic in's sound a little dull compared to line in.4. For the money, wish the highs had a bit more sparkle. Great for monitor use; not sure if I'd use them for mains because of this.5. Would LOVE to see a bi-amp version without the mic inputs.6. I'm curious to see how the boards hold up to long-term vibration. They are not as solidly-anchored as other oem active spkr amps. I'll rate 4.5 for performance & features. However 3.5 for value. The prices on these continue to go up, but items 3, 4 & 6 pose limitations.

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 this amp's balanced line output be run into a balanced mic input of another mixer for recording?

Is the output signal as clean as a standard line-level output?
Asked by: Buzz11
I don't find an xlr balanced output on this unit. It does feature a line level output. If you require xlr balanced you could purchase a direct box.with RCA input jacks and xlr outs.Most modern mixers have both Mic preamp channels and one or more stereo line level inputs. Some mixers have a 1/4" line input on each Mic channel. If your mixer has an input gain control you can easily adjust the incoming level to match the system levels either way.You may need RCA to 1/4" adapters to maximize your options of det-up

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: SPL1000
Apparently, yes to the voltage question.As for the second question, apparently not.

Good for bass guitar AND bass drum mic

How would this item fare if u plugged in a bass guitar AND a XLR Mic going to a bass drum? And would it push a 15" woofer OK for that setup?
Asked by: theruckman
This unit would be just fine for bass guitar and bass drum. How well it would work with a 15" woofer will depend on which woofer you're using. It will provide 250 watts of power to whatever speaker(s) you choose. For full range reproduction of the audio spectrum, you'll most likely want a high frequency driver to work in tandem with your 15" woofer. Without any highs, your bass guitar and/or bass drum will be sorely lacking in definition, sharpness and attack. Adding a tweeter or horn driver will also require a crossover network.

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.
