Dayton Audio MCA2250E 2.1 Channel Class D Plate Amplifier
Dayton Audio MCA2250E 2.1 Channel Class D Plate Amplifier is rated 4.5714 out of 5 by 14.
Rated 5 out of 5 by from Perfect for 2.1 channel systemI am working on a compact computer audio system. This amp works great for small full range drivers. I used an 8" dayton audio dvc sub and Tang Band 3" driver. At first I wasn't sure about the 150hz high pass filter for the mains, but it works great for smaller speakers and still blends well with the sub.

Rated 5 out of 5 by from Great AmplifierI built a custom PC based jukebox and use this amplifier in the jukebox. The jukebox and this amplifier has been used about 8 hours a day, 7 days a week in a functional fitness gym since 1/2011. It sounds great even when the volume is up high.

Rated 4 out of 5 by from Nice compact solution for a small systemI really like this little class D 2.1 amp. It has plenty of power to drive some small sealed speakers and a small sealed sub. Having the subwoofer and mains amp in one chassis relieves the user of additional wires that are even more conspicuous in small setups. I was a little skeptical of the sub amp's quality, but the class D topology once again proves to make very well controlled and tight bass. The subwoofer exhibits much less visible excursion and sounds cleaner at higher levels that my small class AB sub amp.I think PE needs more class D subwoofer plate amp options. Class D seems to consistently outperform AB topology when it comes to bass IMO. I use a Crown XLS2500 in my main system for driving the subs with great results, but it's a little pricey for secondary systems.As mentioned before, the amp does exhibit some hiss during quiet passages and that keeps me from giving it five stars.

Rated 5 out of 5 by from Replaced my Bose System AmpMy Bose cube speakers & sub-woofer plate amp failed again. I replaced it with the Dayton Audio MCA2250E 2.1 Channel Class D Plate Amplifier. Great replacement with plenty of headroom. Bose doesn't repair or sell parts to their older systems.

Rated 5 out of 5 by from repeat buyerI was so happy with the first one, I bought a second to build a 2.1 for my brother. I got a passive sub from a Sony home theater and 2 Sony mb105 bookshelf speakers. Another great match for the power of this amp. Sounds clean and mean. great job Dayton audio! I will the first to buy one when they make one with more power........ hint....

Rated 3 out of 5 by from Good features but noisy power supplyThis is useful module and I'm pleased with the features and sound quality.The downside is the audible noise produced by the switching power supply; soundslike one of the transformers might have a loose lamination. This would be less of an issue if the module was inserted into the back of a subwoofer enclosure. My application has it mounted on the outside rear of my compact sub and sittingat ear level on my computer desk, and you can clearly hear the power supply singing away in the background; it's louder than the hiss coming from the speakers.I would recommend this product; with qualifications.

Dayton Audio MCA2250E 2.1 Channel Class D Plate Amplifier

Where does the sub plug in at the back of the amp? I see connections for the satellites but not the sub...Any help is appreciated...

Asked by: technoguy2000
This amplifier is designed to be mounted in the subwoofer enclosure, so the subwoofer connections are on the opposite side of the amplifier than the connections and controls. The subwoofer connection is a red and black cable.

Will I be able to connect a BT-1A Bluetooth Receiver Module to the Line In internally?

I'm attempting a BOOMBOX project with the power cord being the only cable.One sub,two tweets,two mids,and this amp. Any advice would be greatly appreciated since this is my first project. I'm planing to use the belkin to power the BT-1A.
Asked by: Masterbrk
Using this 2.1 plate amp for a "BOOMBOX" would be total overkill for a boombox and a MAJOR under-utilization of this product. I have righteously rocked backyard pool parties with this plate amp... two Dayton Audio B652's and one Kicker Comp 8" Subwoofer in a TLine. And I barely had the input volume turned up at all. With the input volume low this provided just enough volume that it didn't make it too hard for people to have conversations with each other... but people weren't hearing other peoples conversations... you know.. that sweet spot you need the volume at in the beginning of the event. Before people get tipsy and the event shifts more towards dancing and shakin' it on the floor... then you just walk on over and turn-up the input volume. If you're going to use those Tang Band W4's I'd suggest making TLines for them too! I've now done several TLines with their W3-881SI's and it's amazing the output you can get out of such a small speaker!

Remote Volume Control?

Is there a remote volume control for this amp? Usually I have the sub on the floor under my desk and the volume control is on a cable and sits on my desk.
Asked by: starguy
For this amp, no...Check the cord you have, if it has jacks that are compatible it should work. This is just a passive volume knob common since the eighties... To set it up properly, turn the volume on the wire up all the way, then turn up the satellites until they are as loud as you will most likely ever want them. Next turn up the subwoofer until its nicely blended with the satellites. Now the volume knob on your wire will control both within your preferred listening range.Why would you need it though? If your source is the computer then use the volume control in your OS. Most of the media players available also let you set your mouse wheel to the volume when the player is focused. The same goes for your Ipod, or any other mp3 player or TV, just use the on board volume control.The only time this would really become a problem is if your source was a CD player with no volume control. If this is the case then a remote pre-amp could be used. Anything with a power supply and a volume knob could be used. PE sells the Behringer unit, it is overkill with three too many channels, but with a few adapters could be pressed into service for a reasonable price.If you are the type to muck about some then the Velleman kit is lots of fun for a decent price as well. For about $75 you can have your cake and eat it too. You will get a nice little box to sit on your desk, it will have volume control as well as Bass and Treble knobs!!! It is pricier and you need to get the metal Hammond box, power supply and do some soldering also.

Standalone Sub amp?

can this operate as a stand alone subwoofer amp, without connecting to any satellites?
Asked by: kelv
Yes it can although you may want to consider something like our SA70 or even SA100 for about the same price with more power output instead.

Are the satellites filtered too?

I see there's a variable low pass filter for the sub, are the satellites high pass filtered to compliment this so that the subwoofer and satellite woofer aren't doubling output at the top of the subwoofer range? i.e. standard subwoofer crossover setup.
Asked by: Sonoran
Yes, this utilizes a 150 Hz, 12 dB/octave high pass for the satellites.
