Dayton Audio MCA2250E 2.1 Channel Class D Plate Amplifier
Dayton Audio MCA2250E 2.1 Channel Class D Plate Amplifier is rated 4.4737 out of 5 by 19.
Rated 5 out of 5 by from Replacement for Klipsch Synergy Sub-10 420W AMPI Purchased this because my amp on my Klipsch Synergy Sub-10 420W 10" Sub woofer went bad. It ended up fitting it great after gluing in a small approx 1.5" x 5" block of wood to make up for the shorter amp length. The sound is great maybe not as powerful as the old amp but the bass blends into my overall system to sound better.

Rated 4 out of 5 by from Great for the moneyMy application is desktop 2.1 designed around this amp, 6.5" peerless sub and 4" TB fullrange drivers, designing to fit the amp helps. there are a few features that would be nice as well as a couple tweaks to the cross over arrangement.1) Adding a sub phase switch would be very helpful, in phase if all at one location, out if sub is remote (on floor)2) Dropping the sat output high pass filter to something more usable like 80Hz would be a nice touch. 150Hz is leaving money on the table for most apps.3) The killer app for this plate is desktop hifi, how bout tossing a usb power point on the back?4) Back the overall input gain 6dB would put it line with the rest of the audio world. A little to much noise when gained up fully.I dont review many products with high marks as i'm an audio professional. I give this plate amp a "good" four star rating as its a great concept and a decent performer. A good solid value for the right application.- SoundGuy1

Rated 3 out of 5 by from PLEASE make version 2I love the 2.1 setup with auto turn on. It works perfectly in my application. I HATE the 40Hz high pass crossover on the sub channel, and 50W RMS just doesn't cut it for me. 25W RMS on the satellites is getting it done, but could be bumped up as well. I'm exploring other options, but what I would love to see is a version 2 of this product that addresses these two issues - double the power, and give the subwoofer channel a user selectable infrasonic (high pass) filter that varies between 15 and 40 hertz.

Rated 4 out of 5 by from Good but not greatI originally bought this amp to use for my computer audio system. The audio quality couldn't compare to what I get out of the DTA-2 T-amp, so I just ordered a sub amp and kept using the small DTA-2 with the computer.This plate amp ended up in the basement drum room, where volume is more important than sound quality. It does a great job there! It gets plenty loud enough.Feature-wise, it would be great to have a variable crossover. Also the lack of a main volume control is a bit of a pain. You should get the balance between the satellites and the sub right and then use your audio source as the volume... However, it seems I am always forgetting to do this and throwing off the balance. I'm just used to being able to turn a knob to adjust the volume...

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.

Dayton Audio MCA2250E 2.1 Channel Class D Plate Amplifier

Can a 6" 4ohm 30w subwoofer be used with this amp? I also have a pair of each: 8" woofer, 4" mid and 1" tweeter for each speaker at 8omh each. Would these work with this amplifier? Thx! 

Asked by: rsoto70
Yes, the subwoofer output can handle a 4 ohm load or higher, the satellite outputs can handle 8 ohms or higher.

The satellite freq response goes down to 150Hz but the sub x-over is variable 40~240Hz. Doesn't that leave a gap if i set the sub below 150Hz? I fully admit my noobie-ness.

Asked by: Tom17
yes, if you set the sub below 150Hz and are not using other speakers outside of this than you may have a gap. satellites will get frequencies above 150hz. the sub will get everything below the frequency you set it to.

Does this amp fit well in a particular cabinet that you sell? 

Asked by: shawngraham
The cabinet would be more dependent on the speakers you would want to use with the amplifier. There is no specific cabinet that we would recommend on the amplifier alone. It would only have to accommodate the enclosure cutout: 4-5/8" W x 9-1/4" H, and the overall dimensions: 5-7/8" W x 10-7/16" H x 4-1/2" D.

Are the RCA line inputs internally wired in parallel with the 3.5 mm Aux input? In other words, if I apply a signal to the 3.5 mm aux input would it appear (be available) on the RCA line input connectors? I'm looking to daisy chain the signal. Thanks!

Asked by: Fred66
The 3.5mm is connected to the RCA inputs but not designed as an output. The resistance put on the input signal will then be seen at the Subwoofer. Basically its unfiltered.

Does any one know of a way to control the volume of this remotely? I have a tv with a fixed audio out that I want to use with this. Preferably something small, not an av receiver.

Asked by: Ryanroehl
You will need a separate device (sometimes called a preamplifier) with a remote controlled volume setting placed in the signal chain before the plate amplifier to enable remote-control volume adjustment.

Can the satellite channels be bridged to create a single mono signal? I have a special project where I need one tweeter, one mid, and one sub. I am hoping to run the tweeter and mid in parallel off one bridged mono channel. Thanks.

Asked by: akmiller
No, the stereo outputs cannot be bridged on this amp.
