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 4.5 out of 5 by 136.
Rated 5 out of 5 by from Very high value amplifierJust bought one to power my Polk OWM3 desktop loudspeakers.It is very well suited for that purpose because of the low noise when idling.I also have a SMSL SA-98e mini Tripath desktop amplifier and with this one i hear noise from the tweeters when no music is playing.No problem at 2meters or more away but at only arms lenght away from the pretty revealing Polks OWM3 speakers i can hear the noise and it kinda bothers me.I compared both amplifiers on my JBL Studio 580 loudspeakers and the sound was very similar but this was not the case on the Polk OWM3.Not only does the SMSL has the hissing noise from the tweeters but it also sounded harsh here.The Dayton APA-150 on the other hand is a sweet sounding and very detailed amplifier.No transformer noise or speaker pops when switched on or off either.btw the noise in the video was in the track,it's not generated by the amplifiers on test here.

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.

Driving two Bass Shaker AST-2B-4...better to connect in stereo or mono bridged?  If mono bridged connect the Bass Shaker's in a series?  Would bridged be too much for the AST-2B-4?

Asked by: rsnow
You will get the same output power into each bass shaker with both configurations. I generally recommend wiring one on each channel using this amplifier, but it will not matter either way.

How would you hook this up to a standard PC, 3.5mm audio for true stereo input and output to this amp?  3.5mm stereo to mono splitter then two mono to stereo rca cables one for left and one for right? Sorry newb question. :)

Asked by: rsnow
All you will need for this is a standard 3.5mm to RCA cable which you can see below.http://www.parts-express.com/35mm-slim-plug-male-to-2-x-rca-male-adapter-cable-5-ft--240-065

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.
