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.

Reviews

Dayton Audio APA150 150W Power Amplifier
Dayton Audio APA150 150W Power Amplifier is rated 4.507 out of 5 by 142.
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.

Rated 5 out of 5 by from Great amplifier.Over the last year, I've used this amp with a pair of bookshelf speakers, with a pair of tower speakers with built-in powered subwoofers, and in bridged mode with a center-channel speaker. It worked and sounded great for all of those scenarios. The auto on/off didn't work very well for me, so I just turn the power on and off manually. I like that the amp powers up and down without causing any annoying speaker sounds. After a year of regular use, the amp still works and sounds great. If I needed another amplifier, I wouldn't hesitate to buy another one of these.

Rated 5 out of 5 by from APA150 Power AmplifierWe have a holiday light display that features lights 'dancing' to musical sequences. In addition to broadcasting on a low power FM broadcast band transmitter, sound is provided for viewers who choose to leave their cars or who are checking out the lights in the neighborhood on foot.This is my third year of the display and previously (and the first few days this year) the outdoor sound was powered by an old Radio Shack amplifier the was probably about 45 years old and was rated at about 6 watts per channel.I decided I wanted to upgrade speakers and the power amplifier. In my searches for a power amplifier I found several of the newer digital amplifiers but noted the published reviews were mixed. Plus, I'm an old fashioned analog guy and actually have a few tubes in some of my musical equipment. When I read that the APA150 was class AB and had a 'real' transformer, I decided to make the purchase.I had a very pleasant experience on the phone with Parts Express and found I could get the unit rather quickly for a surcharge of less that $5. It arrived Friday afternoon in time to set it up for the weekend shows. The footprint closely matches the old amplifier I replaced and sits nicely on a window sill.I was very impressed by the heft of the amplifier and the overall appearance. And it sounds great. The combination of new speakers and amplifier are quite noticeable and I've received compliments from those who have viewed our display on foot. In fact some of them preferred the outside sound to their car radios!

Rated 3 out of 5 by from After about 2 years, unit cuts out oftenReally liked this unit, though the auto off never really worked well for me. I leave the auto switch to 'on.'Within the last few months, it has begun to turn off while I'm playing music. If I turn the music source off and on it works again. The unit also recently makes an odd cycling/clicking/scratching noise. Which I don't understand, because there ought to be no moving parts in there, right?Has been a pretty good unit, but should've lasted longer. I will be replacing it with something else.

Whats the input sensitivity in volts ?

Asked by: ashdd

What size speaker is in this unit? 

Asked by: JazzyDan
This does not have a built in speaker, this is just an amplifier to power a pair of speakers.

i have a tv with  bose speakers surround sound and was wondering if this would work to power the speakers, i have no room for a big clumsy receiver,just want something small

Asked by: rooster479
This amplifier is only designed to provide power to two speakers (a stereo left/right pair); it cannot provide surround sound.

For some time I've had these connected to the PC speaker jacks.  However, the 3mV trigger is not effective at turning then on.  Any suggestions to increase pc speaker voltage output?  Will a stereo distribution amplifier help?  I need auto off too.

Asked by: greyleopard66
I use one of these amps at my desk, connected to my PC. I often turn down the volume setting on the amplifier, then turn up the PC sound card's output, and I'm able to get much more output than I need this way. This also gives me more fine control over the output level using the PC's volume slider within Windows. I would recommend a similar arrangement for you.

What are the FTC ratings for this amp, both channels driven?

Asked by: Colt4531
The power ratings are specified in RMS not FTC ( continuous). The RMS is 75 Watts per channel into 4 ohms. 150 watts into 8 ohms.

I have recently put in a 5.1 surround sound system in my basement.  I have one passive 12" 400W peak power sub.  Would this amp be a great choice in powering that sub?  Thank you.

Asked by: Lambo23
Yes, as long as the sub is no less than 4 ohms for stereo mode (perhaps a dual voice coil woofer) or no less than 8 ohms in bridged mode.
