When purchasing this amplifier, I was a little confused at first. This confusion was due to the fact the price felt too cheap for it to be a decent product. However, I went ahead and bought the amplifier anyway. And to my surprise, this was the best amplifier I have ever purchased.
When you initially buy the amplifier, it takes a couple of days for you to totally get along, but when you finally do, it is totally worth it. I’ll break it down slowly, as to what makes this amp one of its kind.

Dayton Audio Apa150 Review 
At the first look, you’ll notice the profile of the amplifier, which is smooth. The square face is some-what around 6’’. The brushed metal faceplate includes just a power button and a specialist blue LED, as well as a volume handle of extremely smooth activity.
By and large, the look was exceptionally perfect and basic – rather exquisite, belying the amazingly low price tag of this amp. The blue LED is, however, a little too bright, which might be a problem for some customers.
By the looks of it, the amplifier does look like it is cheap. However, the looks and the price is massively deceiving when it comes to the performance of this amplifier. Even without a modern look, the sleek design perfectly fits with almost all sound systems.
Dayton Audio Apa150 150w Overview:
The back panel includes a 3-pin IEC input, switchable somewhere in the range of 120V and 230V. Additionally on the back were the pair of 5-way speaker inputs, line level inputs in 1 arrangement, and line-level outputs in the other.
The amplifier lacks a remote control because there is no switching of the inputs. However, I do not care about that much and believe that living without remotes is doable.
Vent slots are also present in the rear panel. These slots are also seldom required. Afterward, there is the auto-on switch, mono switch, and low pass controls.
Considering the elements, adaptability, and wide array of features this is a very thoroughly examined amp. It also conveys enormous value for money, because of the low price.
The amplifier really does it all, being a regular stereo integrated amplifier, a subwoofer amplifier, and a home theater amplifier. This multi-purpose nature of the amp is boasted by a low pass filter that can be varied from 50-150Hz.
The amplifier has a 18dB/octave slope. The amplifier functions at full bandwidth, when in “Flat” mode. To use it as a subwoofer amplifier, the “Lowpass” setting has to be used. The crossover point varies within 50-150Hz.
This APA-150 utilizes a fairly traditional setup and interior construction: Class AB activity with 2 transistors for every channel, introduced on a shut heatsink, associated with a cooling fan that initiates when the inner temperature of the heatsink is excessively high.
However, this only happens when the amplifier is operating at maximum output for straight hours. However, the cooling fan is very silent and does not create any noise.
To set the “Mono” mode on this amplifier, all you have to do is to switch it in the rear panel. Then you’ll be able to receive 150 watts on an 8 Ohm load.
With 25.8 volt yields of output, the amplifier uses a toroidal transformer at 750 watts. The power supply segment is finished by 2 electrolytic 6800 uF/50 volt covers provided by TEC.
It should be considered that this is an amplifier, and not a pre-amp which means sometimes sources might not be able to drive the unit properly. This usually happens because of low input sensitivity and can be corrected by adding an active preamp.
The amplifier provides extensive room control because of the adjustable 50-150Hz low pass crossover. Lastly, the 5-way binding posts are Gold-plated and are built to accept up to 8 AWG wires.
The versatility of the amplifier is the biggest highlight of this product. The amplifier delivers 75 watts into 2 channels, but at the same time can also deliver 150 watts into 8-ohms. For the latter one, the amplifier needs to be in the “Mono” mode.
The amplifier allows bi-amp configurations via a full range line-level output. The amplifier also functions as a subwoofer amplifier through the low-pass filter.
Another feature that is mesmerizing in the amplifier, is its auto-on sensor. The flat sound produced is clear and amplified beautifully. The versatility of the amplifier makes it multi-faceted and exceptional.
- Stereo mode – amplify speakers for surround playback
- Bridge-mono mode – power a center channel speaker
- Low pass filter – for a subwoofer/ tactile transducer
- Full range line-level outputs – bi-amp/daisy chaining amplifiers
Q- are Dayton Audio amplifiers the best?
Given the price range, the amplifiers are exceptionally good. They are highly recommended if one has to use their versatility, where they actually provide the most advantage.
Q – what is a power amplifier?
Any amplifier that converts a low-power signal into a high-power one, is termed as a power amplifier. In easier terms, they increase the magnitude of the power of any given signal.
Dayton Audio APA150 is a powerful amplifier, which is brought to us by Dayton Audio. These manufacturers have aimed at providing a multi-faceted solution to the consumers with different needs, this one-stop solution for a stereo amp, subwoofer amp, or even a bi-amp is far ahead of its time. Given the low price point, it is highly recommended. It can also be used to power multiple channels and has a low pass crossover which allows you maximum room control.
