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.

Reviews

Dayton Audio PMA250 250W PA Module with Mixer
Dayton Audio PMA250 250W PA Module with Mixer is rated 4.1053 out of 5 by 38.
Rated 4 out of 5 by from Solid full range plate ampGood sound quality. A little heavy compared to the class-D plate amplifier available on the market. But class-AB does sound less harsh on HF. Heat sink is a good size. It sticks out over 1", so unless it is recessed into the cabinet, it will stick out.

Rated 5 out of 5 by from Perfect for my useAfter much deliberation, I ordered this amp. Pleasantly surprised on arrival...everything works properly. Measurements for the cutout were slightly undersize, but far better than oversize. Clean, clear audio. I installed it in one of my pa speakers (the one I built years ago with parts from you. Good price for a versatile product.

Rated 5 out of 5 by from Wonderfully Versatile Amp..!I have owned one of the Dayton Audio PMA250 250W PA plate amplifier for 2 years now and am very happy with it. I originally built it into a very small ¾ cubic foot enclosure for a JBL GTO 804 speaker (JBL's recommended size for the 4 ohm 8" 400 watt RMS speaker). I built and used it with a sub-based synthesizer for my kick drum and drove it hard! It worked great till the voice coil in the 'beefy' little speaker finally burned out. I then used the same amp to power the "Leslie" tone cabinet for the keyboard player's B3 and it worked fine with plenty of power (150 watts into the 8 Ohm load) with twice power of the original "Leslie" amp plus it has bass & treble EQ also. Now I'm building a new box to use it for my kick (bass) drum again. This time using a JBL GTO 1214 (12" 400 watt RMS, 4 Ohm) driver. I have speculated however that using these speakers with such strong magnet structures probably degrades the performance characteristics of the amp so I fabricated a steel 'can' shield for the new speaker and will also create a 'compartment' out of galvanized steel to shield the amp from the speaker magnet as well.I am very happy and pleased with the "Dayton Audio PMA250 250W PA" plate amplifier a workhorse & powerhouse, you'll find it works as advertised!Kudos to the Dayton Audio design engineers at Parts-Express. To make improvements to the line of full range plate amps, why not add a light weight steel 'chasis' box to the back of the amps to protect them form the powerful magnet stuctures of todays speakers? And more 'gain' to the line imput of the PMA250.

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.

A signal to noise ratio of only 73db? Wouldn't this introduce a large amount of hiss from a high-sensitivity horn driver?
