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: 5.6" H x 5.7" W x 12.8" D.

Reviews

Dayton Audio APA150 150W Power Amplifier
Dayton Audio APA150 150W Power Amplifier is rated 4.5 out of 5 by 140.
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.

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!

Dayton Audio APA150 150W Power Amplifier

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.
Answered by: MattP
Date published: 2014-12-10

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?
