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 Low pass filter: 12 dB butterworth Class A/B design topology Input sensitivity: 1V 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. USA Power cord included.

I've had one for a couple of years now and I'm very happy with sound and quality and always wanted another one to run each one in bridge mode. Don't know if this is considered true monoblocking but they do sound as good as my ears can tell to more expensive amps. I would recommend these to anyone who listens to average to a little above listening volume. I have mine setup for two channel audio and two channel home theater in my living room. I gave 4 stars only because there is better amps but not for this price point.

I got 8 years of occasional (weekly) use out of this amp until one day, the right channel decided to stop working. That seems like it should be enough to be satisfied, but in my opinion, there's no good reason a piece of equipment like this should fail after that amount of time. I have Rotels that are 5 times as old and still kicking.I doubt I will be buying another Dayton Audio product.

Using a Dayton APA150 to drive a 12 subwoofer on 5.1 Channel surround sound home theater system (room is 13 X 20 ft.) Sounds crisp and clear, no noticeable distortion. Tried pushing a 150 watt RMS sub and subwoofer was breaking up a max power, replaced subwoofer with a 500 RMS woofer I had laying around and now it can shake the windows ( just little) at max power (250 RMS sub is probably a good match). This unit is great for music movies because cooling fan only turns on during heavy loads. You can get more power for your buck but most units I saw in this price range had loud continuous running fans that you can hear when watching movies and/or higher distortion. Automatic on/off and quality connections are also nice features

I tried a Fosi TP-02, Emotiva Basx 3, and this Dayton Audio APA150 on TWO 50w 4 ohm Aura Bass shakers. This Dayton Audio barely even put out a whimper. I was completely shocked how vast in difference in power there was after all the rave reviews. My best metaphor is by comparison to cars and speed. The Dayton Audio was like a Ford Ranger hauling a bed full of dirt. The Fosi Amp with only ONE Aura bass shaker was like a Camaro SS. And the Emotiva Basx3 like a Corvette.Bass shakers! Go with a Fosi TP-02 per bass shaker for the cheapest option. U can use it with two but it's kinda a tease. Otherwise, find something that feeds the bass shaker a minimum of 100w rms.You will waste your time with this Dayton Audio. It looks nice but those 60-70w rms, 120w at 8ohms stats are BS. I really wanted this to work because I didn't want two Fosi amps in my entertainment center. However I would take one Fosi amp over 11 of these wimpy Dayton Audio APA150'S.

I have to say for the price l'm very happy, I bought an old school stereo console for $40.00 and went to work rebuilding it. I am using 2 of these amps to power everything one for my mids and highs and the second one for the console mounted subwoofer bridged in mono. This project turned out awesome and has sound to match. I only wish Dayton Audio offered this same compact amp with a high wattage output. The speakers are also Dayton Audio matched up with a Skar Audio 8 sub l had just sitting around doing nothing. Today l've had the music playing for about 6 hours straight and niether amp is even warm to the touch.
