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 4.4928 out of 5 by 138.
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.

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 during the 2013 holiday season.Highly recommended!

Dayton Audio APA150 150W Power Amplifier

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.

on a scale of 1-10 how well will this power a 12" 4 ohm sub that is hungry for power and has a 325 RMS rating and a 1300 peak?

I purchased this amp 4 years ago.  Worked fine until last week when it started to produce a clicking sound in the amp (not the speaker).  Turned off, then turned back on.  Clicking gone, but amp not producing power (even though it is on).  Help please.

can this amp drive a pair of power hungry 4ohm speakers ?

Asked by: Rich01
Yes this will work with any standard 4 ohm speaker as long as it is in stereo mode. Power hungry usually means inefficient. This will limit the output capabilities depending on the actual speaker sensitivity, but the amp will have no problem driving that load.

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.
