Dayton Audio DTA-2.1BT2 100W 2.1 Class D Bluetooth Amplifier with Sub Frequency Adjustment

The price isn't justified as 20000 in India. at that price stretch anyone should go with yamaha or cambridge audio stereo receiver or even pioneers.

muy pequeño versatil y bueno por su tamaño

The dayton audio dta2.1bt is a very powerful, very compact unit. I currently have it hooked up to two onkyo bookshelf speakers and an onkyo 200w passive subwoofer. I wasnt expecting much from the 100w subwoofer channel on this amp but it actually shocked me with how loud it was able to get the subwoofer and how clean the sound is even with the volume knob on full gain. The crossover frequency adjustment is also very nice. I have mine set at around 80hz because the bookshelf speakers have very good midrange response, however, raising the crossover to 120hz allows for higher mids and punchier bass if people decide to use smaller satellite style speakers. At around 60-80hz is where i like my crossovers set and it performs very well with notes in that frequency and even lower. The speakers are rated higher than this dayton can push and that being said, there is no distortion i can hear from it even at full volume on very demanding tracks. Awesome unit, easy interface and Bluetooth connectivity, the tone knob accentuates high frequency levels without being too harsh. Very nice unit, i love the all metal frame on it and can tell itll help dissipate heat (even though it did not get even remotely hot after 30 minutes of full volume action).

The media could not be loaded. I've been using Dayton Audio products for over 10 years. The amplifier was paired to a high-end $1,800 gaming laptop via AUX and connected to the Klipsch Reference R-50M speakers and the Dayton Audio Ultimax UM12-22 subwoofer.The power supply that comes with the amplifier is rated at 24VDC at 4.0A. That means the power supply has a power output capacity of 96 watts. If you want exactly 100 watts, I'd recommend replacing the power supply that can output more current. You will destroy the amplifier if the voltage is higher than 24VDC since the amplifier does not have a protection mode. It is not stable at 1-2 ohm. It is also not bridgeable as well but that doesn't make it a bad amplifier.Overall, this is a great amplifier for anybody looking into a 2.1 sound system.

Powerful and solid amp in a small, clean package. I'm using this with two marine speakers and one tactile transducer in our bathroom. TONS of power, I'll probably only ever run this at 1/3 to 1/2 capacity. Dayton Audio makes quality products, and I'm proud to be the owner of several!

I've found this to be a good stand-alone amp for connecting my Alexa to some in-wall speakers and a passive sub (all running 8 ohms). Good high-end volume, no distortion on the levels where I typically run it. Very happy on the amp side.BUT - the unit defaults to bluetooth source after power fail/cycle. My main feed is line-level. So when power goes out, disconnected, etc. you have to physically press the button on the unit to get back to line-level input. Not a show stopper, but the unit is in my basement. So beware of this limitation if you plan on locating the unit in a less-than-convenient location.I chose line-level to avoid latency issues via bluetooth for speaker groups - the amp this replaced had some DSP in the chain that made multi-room audio just enough out of sync it sounded like we were in a stadium.
