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 4.1212 out of 5 by 33.
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

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.

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.

I have a pair of bose series 802, my question is would that plate feet on the back of my unit? The fact is I don't know the size of the plate, and do you think it would sound good considering I have the bose equalizer already.

Dayton Audio PMA 250, Does this amp have a crossover in it?

Asked by: Taber
No, this amplifier only has a single full range output what would need to be fed into a crossover for a two or three way speaker.
