Product Details

Dayton Audio APA150 150W Power Amplifier

Amplifiers today need to be multi-faceted to keep up with the task at hand, and versatility is the foundation upon which the Dayton Audio APA150 is built. When configured in stereo mode, amplification is provided to a pair of speakers for stereo or surround playback. Select bridge-mono mode and the APA150 is ready to power a center channel speaker, or a subwoofer/tactile transducer when used with the on-board low pass filter. Full-range line-level outputs allow for daisy chaining amplifiers for a multi-room whole house audio system or for bi-amp applications. The APA150's smaller chassis consumes less space than conventional amplifiers, making placement options virtually limitless.

Key features of the APA150 include high current, discrete power transistors (used in premium amp designs), a hefty toroidal power supply transformer, low-noise forced air cooling, a fully adjustable—and defeatable—electronic 50-150 Hz low-pass filter (18 dB/octave), and complete protection against electrical shorting and thermal overload. Also included are auto-on/off, silent turn-off with no audible transient, gold plated RCA inputs/outputs, and 5-way binding posts.

Features and Specifications: • Measured power output: 2 x 75 watts RMS (into 4 ohms @ less than 0.01% THD) • Signal-to-noise ratio: greater than 100 dB • Class A/B design topology • Input sensitivity: 1 V • Input impedance: 47k ohms • Auto-on sensitivity: 3 mV • Voltage requirement: 120/230 VAC, 60/50 Hz • Dimensions: 5.6" H x 5.7" W x 12.8" D.

Dayton Audio APA150 150W Power Amplifier
Dayton Audio APA150 150W Power Amplifier is rated 4.5137 out of 5 by 146.
Rated 4 out of 5 by from Compact AmpI bought this over a week ago, used for shakers in my home theater setup. Great power for a small versatile amplifier. High quality speaker terminals. Only reason for 4 stars, is that it doesn't have gain control on it, had to purchase an in line gain booster. It would be perfect for my project if it had it. Got a good price on a refurb unit. Thanks Part Express!!!!

Rated 5 out of 5 by from Extremely good value in HIFI. Robust build.I purchased two of these as "refurbs" from PE... Neither of them had a single mark on them and no signs of refurbishment (pain scratched from the screw heads, etc.). So far as I can tell they are new and the pair set me back significantly less than two benjamins with free shipping. Each has a date code from 11 months ago (fresh stock). The toroidal transformer in them is MASSIVE for a 150 watt amp and the capacitors appear adequate. This amp has been tested by other to perform cleanly down to 2.5ohm and deliver >200w rms into a 6ohm load in bridged mono operation. I'm driving a pair of Dayton Audio RS621CB independently (minimize cross-talk) with the two amps in my office. The system has been calibrated to my listening field with REW and a very small investment in calibration equipment from PE. Could not be much happier.The fans are never going to run on these amps driving 6" bookshelfs in tandem and I suspect the amps will last a very long time. No issues with the autopower threshold like others have expressed (but my soundcard has good output capability). These are VERY quiet amps -- with the system running (PC, sound card, amps) you can turn the amps to full-gain and there is no noise detectable. It's really hard to believe China can make something this reasonable in design and build quality for PE to sell this cheap. I suspect that Emotiva invested in the complete development and manufacturing of this amp (did all the groundwork) before they disappeared and PE just licensed the design and keeps the orders active for the manufacturer. With the world economy not looking very spectacular, it's probably a pretty good time to buy these while you can.

Rated 5 out of 5 by from Seriously great amp for the moneyI bought this to use as a simple power amp between my Polk bookshelf speakers and a pre-amp I already owned and use for my inputs. I just needed something with 40 or so amps of clean(ish) power for listening to vinyl. I can really crank this little amp quite loudly with very little distortion. It's a great amp for a small setup.

Rated 5 out of 5 by from Works great and very compactI bought this to power 2 Aura bass shakers and it works great. Great customer service from the techinical team as well!!! I decided to do my test/demo using "Fury" and wow...plain and simple - WOW!!! What a great addition to any home theater set up! Definitely recommend!

Rated 5 out of 5 by from Fine little amp for what it isThis is the second one I've purchased. I daisy chain them for speakers in different rooms. Having volume controls on each amp makes this a cinch. Don't be misled by the power rating. The manufacturer doesn't provide a stereo power rating for 8 ohm loads, only bridged mono into 8 ohms or stereo into 4 ohm loads - so caveat emptor.

Rated 5 out of 5 by from Versatile and dependableI'm looking for a new amp right now, and just decided I had to let everyone know about this one. I've had mine for a couple years, and it gets the job done! I've used it in all it's different capacities and it has done great with all of them.At first, I was using it for my pair of Dayton Classic 8" MTMs, but it wasn't quite enough to bring them to their full capacity. That was my first build. Then I made a smaller MTM pair for the Iron Driver competition in 2012 which this works very well for. I also built a big vented box for 4 Dayton DVC 8" subs wired in parallel-series-parallel for a 4 ohm load. This isn't rated to handle 4 ohms bridged, but I did it anyway, and it did well for those too, although obviously it didn't bring them to their max capacity either.THEN, I've added a 15" Bravox sub to my system, and so I have the big towers running on an iNuke1000, the small towers on a HT receiver, and the quad8DVC on one channel, and the 15" sub on the other channel of this amp. I have a splitter coming out of my mixer which sends stereo to the iNuke and stereo to this amp which is passing thru to the HT receiver. Using the built in LPF which works great. I know this is a crazy setup, but it actually has been working very well, although I'm running both towers full-range, which isn't ideal.The only two things I could dream of that would make this amp better were if it had more power (which doesn't matter for me anymore because I can use my mixer as a preamp, and this can drive both of these 4 ohm subs plenty) and if the auto-on didn't turn off when you're playing very low level music, or there's a quiet moment (which also doesn't matter for me because my whole system is always on and I just using my power strip for that.)All in all, for the price, this amp is good enough if it were just RCA in and speakers out. The extra features make it perfect for people who tend to use a variety of setups. It's built very well, looks nice, and has never given me a bad sound. It has the potential to put out much more power than rated, and has only even gotten hot when it's been running way over rated power for a long time. Still, after all I've put it thru, it's never failed me. I've blown a couple amps in the past to be honest. I tend to push them. This one is a survivor!My feedback on this amp is that it would be great to add a sub to your stereo setup if you have a high sensitivity sub, or don't listen at very high volumes. It would be great to have around in general for a stereo setup, or a backup, or testing amp. And from my experience, it can put out a really nice level if you use a preamp. Of course, if you blow it, you can't blame me. I'm just some guy. But I have bridged at four ohms and played heavy dance music for hours at much higher levels than it would put out without a preamp, and it didn't even flinch.

Dayton Audio APA150 150W Power Amplifier

What power output will this amp provide in stereo with a pair of 8-ohm speakers? I know it will be less than 75W but will it be half (32.5W)?...or better, or worse?

Asked by: VirtualRain
There is not an 8 ohm rating, but you can expect slightly more than half of the 4 ohm power. I would expect around 35 watts per channel when driving an 8 ohm stereo load.

Is a 1.6A fuse included for 220V operation? If not, is this the correct fuse? http://www.parts-express.com/littelfuse-16a-gdc-type-5-x-20mm-slo-blo-fuse-5-pcs--071-860

Asked by: Aijan
The fuse included is only for 120 VAC input. The fuse in the link will work for 220 VAC input.

I am running a 2.1 system for a computer with an integrated sound card, Because there is not a pass through for a sub, is there a possibility that the sub and the speakers will be off? I mean off in a sense when they give sound, it is a powered sub.

can I use this amp in Australia?. it looks like it has a voltage switch.

Asked by: bigzee3
Yes this does have switching input voltages but you will need to swap the fuse for use on 220V.

Hello Parts x, I bought this amp along with two bass shakers.  Do you have a recommended connection diagram?  I can place a splitter on my LFE out but where should it go on the amp. Also, i read that it is best to hook up two bass shakers in parallel ?
