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.

Dayton Audio APA150 150W Power Amplifier
Dayton Audio APA150 150W Power Amplifier is rated 4.5135 out of 5 by 148.
Rated 5 out of 5 by from Nice Desktop PC Music Collection Power SupplyI purchased the Dayton APA150 amplifier to replace a dead Onkyo receiver as the amplifier for my PC based music system. So far it's made for a good fit within arms reach on my desktop. Simple, no frills, smallish footprint with sufficient power to push my Bowers & Wilkins 685's. Perfect for my needs.I manually turn the amp on/off, so the fickle auto on/off feature reported by some doesn't effect me. And yes, you can't miss that blue high intensity power-on LED.

Rated 4 out of 5 by from Amp for Bi-AmplificationThis is a good amplifier for bi-amplification, specifically the tweeter channel on the CBK36K speakers. The DC offset of the amplifier is less than 5 mV and when I turn the amp on and off briefly to simulate a power drop out (thank you PEPCO) there are not thumps, crackles, or any other sounds.I would like to have tried your tripath class-D amps but there DC offset was several tenth's of a volt which is too much for the tweeters. If the tripath is built for you (Dayton) you should have a DC offset adjustment built into the cicuit.

Rated 4 out of 5 by from Compact AmpI bought this over a week ago, used for shakers in my home theater setup. Great power for a small versatile amplifier. High quality speaker terminals. Only reason for 4 stars, is that it doesn't have gain control on it, had to purchase an in line gain booster. It would be perfect for my project if it had it. Got a good price on a refurb unit. Thanks Part Express!!!!

Rated 5 out of 5 by from Extremely good value in HIFI. Robust build.I purchased two of these as "refurbs" from PE... Neither of them had a single mark on them and no signs of refurbishment (pain scratched from the screw heads, etc.). So far as I can tell they are new and the pair set me back significantly less than two benjamins with free shipping. Each has a date code from 11 months ago (fresh stock). The toroidal transformer in them is MASSIVE for a 150 watt amp and the capacitors appear adequate. This amp has been tested by other to perform cleanly down to 2.5ohm and deliver >200w rms into a 6ohm load in bridged mono operation. I'm driving a pair of Dayton Audio RS621CB independently (minimize cross-talk) with the two amps in my office. The system has been calibrated to my listening field with REW and a very small investment in calibration equipment from PE. Could not be much happier.The fans are never going to run on these amps driving 6" bookshelfs in tandem and I suspect the amps will last a very long time. No issues with the autopower threshold like others have expressed (but my soundcard has good output capability). These are VERY quiet amps -- with the system running (PC, sound card, amps) you can turn the amps to full-gain and there is no noise detectable. It's really hard to believe China can make something this reasonable in design and build quality for PE to sell this cheap. I suspect that Emotiva invested in the complete development and manufacturing of this amp (did all the groundwork) before they disappeared and PE just licensed the design and keeps the orders active for the manufacturer. With the world economy not looking very spectacular, it's probably a pretty good time to buy these while you can.

Rated 5 out of 5 by from Seriously great amp for the moneyI bought this to use as a simple power amp between my Polk bookshelf speakers and a pre-amp I already owned and use for my inputs. I just needed something with 40 or so amps of clean(ish) power for listening to vinyl. I can really crank this little amp quite loudly with very little distortion. It's a great amp for a small setup.

Rated 5 out of 5 by from Works great and very compactI bought this to power 2 Aura bass shakers and it works great. Great customer service from the techinical team as well!!! I decided to do my test/demo using "Fury" and wow...plain and simple - WOW!!! What a great addition to any home theater set up! Definitely recommend!

Dayton Audio APA150 150W Power Amplifier

How would you connect this amp to a laptop

Asked by: fallszero
You would either us a 3.5 mm to rca cable , or a audio interface that supports rca outputs

Want to set this up for a 2.1, but have a powered sub (JBL ES250PBK) without speaker level inputs, just line level. The 2 speakers are premier acoustic pa-6s (don't laugh, they sound pretty decent)

Asked by: Supernerd
The only way this will work is to either split the output from the source and feed it to the amp and the sub and control the volume with the source, or send the line output from the amplifier into the sub and control the volume individually.

How would I configure the Dayton APA150 with stereo in, 1) going out to a single voice coil (mono) subwoofer, and 2) daisy chained to send the high pass signal to a stereo amp?

can use this amp with Malaysian voltage (220-240v) ?

Asked by: carlead
Yes this will accept 110-220VAC input via a switch on the back.

Is it always class B or sometimes (the very first watts) also A?

Asked by: Kamis
This is a class A/B amp topology so its intended to be more efficient than a class a but still reduces distortion of the push pull design of class B designs.

I am currently running two APA100's on the Electrovoice Evid 6.2's in my backyard (the "party" speakers).  How would the APA150's compare to the APA100's?  I like the smaller footprint but I would not want to give up any power or SQ if I were to switch.

Asked by: Electrical Engineer
The apa150 should have similar sound quality, and just a little more power. It is probably not enough to make an audible difference though so the main advantage would be just the size and shape of the amp.
