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 impedance: 47k ohms • Auto-on sensitivity: 3 mV • Voltage requirement: 120/230 VAC, 60/50 Hz • Dimensions: 5-1/2" H x 6" W x 11-1/2" D.

Dayton Audio APA150 150W Power Amplifier
Dayton Audio APA150 150W Power Amplifier is rated 4.4963 out of 5 by 135.
Rated 5 out of 5 by from Worth the money spent so far.....Shipping was very fast (to a friend in NYC whom I was visiting for a week, the import duties are very high) and the unit came very well packaged. I'm not to sure about the complaints about auto-on sensitivity because I'm having no problems in that department. The power light is a little bright but definitely not a deal breaker, and remember the price! Like I said, well worth the money!

Rated 4 out of 5 by from Nice amp but...Bought this amp to power Infinity speakers connected to my TV and a cd player - yes I know only one out but I planned to build a switch box. Amp is nice sounding, like no sound but the auto on/off feature does not always work - I miss the first few seconds of music before it turns on, and if the CD is quiet, it never turns on. I stopped using that feature but it I would have like to use it.

Rated 5 out of 5 by from Excellent Amp - Ridiculously Low Price!I purchased my APA150 during the 2013 holiday season and have been enjoying it ever since. While it may not be as good as the best amplifiers I own (which are much more expensive) this integrated amplifier faithfully honors the music.That is to say that it adds nothing unpleasant to the music, and as such, errs by omission as opposed to commission.It is a nicely built, compact piece of hi-fi gear that has this audio enthusiast wondering why I have spent so much money on audio amplification in the past.When driven by the music software in my netbook computer, the APA150 easily drives my 1980's Linn Kan I bookshelf monitors to very loud levels. The APA150 is rated at 50 wpc into 8 ohms when used as a stereo integrated amplifier, which works quite well for powering any computer monitor or bookshelf speaker that I can think of.The APA150 is easily worth its $200 list price and was a bargain at the $125 price I purchased in at on Partsexpress.com during the 2013 holiday season.Highly recommended!

Rated 4 out of 5 by from Nice little amp for the price !This is a great little amp. I have it hooked up to my iMac and some Bose Acoustimass "cube" speakers with the Bose subwoofer and it sounds great. Plenty loud for this application, for me. Like many of the other owners though, I too am having problems with the "auto on/off" function. The amp keeps shutting off, so I boost the input volume and the amp comes back on but then shuts off again later on. I would have rated it 5 stars had it not been for this. Since I'm on my computer pretty much everyday, I just leave the amp on all the time now and it barely gets warm at the volumes I use. I've had it turned on and running now for about 2 months. I might try hooking up this setup to my TV next and see how that performs. Very happy so far with the sound of this amp and the quality of construction for the price.

Rated 4 out of 5 by from Very good for the moneyI purchased this amp so that I could use my existing rear-channel amp (Parasound 275) bridged in mono to get more power to my center channel. For the price, this amp is hard to fault. Bear in mind, however, that the 2 x 75 watt rating is for a 4 ohm load. I was using the Parasound to run the rear channels before. The Parasound is rated at 2 x 75 w @ 8 ohms and 120 w @ 4 ohms...a huge difference.My rears are Energy RC 10s, rated at 91 db, so I figured the Dayton amp would be plenty. I was wrong...it has just enough power to get the job done, and no more. For music listening, I keep the amp's volume (gain) control at the 12 o' clock position, and for music I turn it all the way to the right. It has about 1/2 the power and volume of the Parasounds, as the ratings would suggest. Please don't think I'm being critical here...the Parasound is nearly four times the price, and has higher current reserves.Sound-wise, I was missing a lot of detail I had previously enjoyed. I switched out my Signal Cable Analog Twos for a pair of Signal Cable Resolution Reference (silver) cables, and the clarity, detail, and punch of the Dayton Amp came alive...very close to the Parasound. I would prefer more power; say, double. But still this is a lot of amp for the money. It is well built, and looks like a much more expensive amp.A couple of quibbles, however: When I first opened the box, the amp had a distinct "burnt" smell, almost like an electrical odor (which, of course, would definitely not be the case, as it had not been plugged in). The smell is almost completely gone now, and I would guess it is related to a plastic or glue of some kind. The other quibble is the blue light, which is distractingly bright, particularly when the amp sits high on a component rack, as in my configuration. I solved that problem by taking two self-adhesive round felt pads and poked a sharp hole in the middle of them with an awl. I then stuck the pads together and put them over the light, and, "voila"--the distracting blue light became a muted "dot" instead. If you don't need a lot of power reserves, this amp will serve you well. It is one of the best values I have encountered in hi-fi.

I just bought the Apa 150 amp.  I have four aura bass shakers.  How should I wire these ? What settings should I use in the back ??

Asked by: SteveD15
The only way to wire four bass shakers to this amp would be two on each channel, wired in series.

I like to purchase 2 amps run them mono to some large 4 ohm floor speakers can this amp handle that load?

Asked by: cpontiac1
Unfortunately these will only handle a 4 ohm load in stereo mode and 8 ohm load bridged.

I am looking at purchasing an amp to power 1 Clark Synthesis TST209. Eventually buy a 2nd one for same couch (unless single is adequate). How would I set up powering the transducer & not have it overpowered by the amp? Is this amp sufficient for 2 Clarks?

Asked by: krispjorn
The best way to wire one or two of the Clarks to this amp is simply to wire one to each channel of the amplifier for the full 75 watts of output power.

Asked by: cagusthyde
This amp is only stable to 8 ohms in bridged mode.

When I connected this to my Denon AVR-2802 receiver the sub hardly makes any noise. I found if I run the signal to this amp then to the receiver it sounds great except I loose the ability to control the volume with the receiver. How can I fix this?
