DTA-2.1BT2 200W 2.1 Channel Class D Bluetooth Desktop Amp

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).

I tried many audio solutions for my pc, and wanted to run my passive sony speakers (SSCS5) and a passive subwoofer from my old home theatre setup. This ticked all the boxes and sounds great. It is extremely loud for its size too, so much so that I find myself usually using it at about 20% volume or less. The subwoofer frequency crossover knob is great and reminds me of much more expensive amps, and the overall sound is pretty solid for this price range. I tried other similar amps and this one stood out as the best quality to me. My setup uses RCA to 3.5mm because I didn't want any bluetooth audio delay while gaming. I also ended up needing to get a ground loop isolator to prevent the computer noises this amp was amplifying along with the audio signal, but that isn't Dayton Audio's fault, but rather my own homes power being dirty. The bluetooth quality seems high as well, though as I mentioned before, it presents a slight lag while gaming, which doesn't work for me. For music, though, it sounded just fine. Definitely recommended over the cheaper alternatives- save yourself a little time and just go for this one if you have a passive speaker setup like me, I tried a whole bunch of them!

I honestly hate that this doesn’t auto disconnect the prior user if I want to use it and wasn’t the last to be the one listening, but I can’t complain much due to the price. My other two choices cost four times as much, and since this is just used to power my outdoor speakers on the porch, won’t get too bent about it. If I were using this as the amp in a more frequently listened to area, I would hesitate because of the aforementioned feature (unless I lived alone. Then: who cares!). Sound-wise, It shocks me how good it sounds compared to the old Denon I had powering my porch speakers. Bluetooth hasn’t dropped out ever, and it has a nice, small form-factor that isn’t as obtrusive as the receiver that it replaced. Glad I found this for the purpose it serves!

I like Dayton Audion equipment. I purchased this unit to replace a Fosi Audio BT30D that worked for a day and then started crackling. Unfortunately, this unit was another dead-end. I had it hooked to a pair of Polk T-15s (8 ohm) and passive sub (6 ohm). Sound is fed from PC sound card. When I first plugged it in every went fine. Easy to hook up, sound was good. The on/off/select button, as many other reviewers have commented on, worked pretty well I thought - a clever way of saving space. it didn't take long to notice that this unit did not sound as rich and vibrant as the Fosi - that was pretty clear. Good sound quality but not great. Then came "the buzz". I came back a few hours later, turned it on, and quickly noticed noise in the music stream. I killed the music and found a loud tone coming from the amp. Power is coming for a pure sine wave power supply so that wasn't the problem; switched sources anyway and same thing. The signal cable isn't close to any interference - just to be double sure I changed it - no difference. The tone is not on the sub side, just the stereo side - left and right. This tone wasn't there when I first turned it on so I suspect something toasted itself inside the amp or the power supply. I never pushed the unit anywhere near its limits. Personally, I think all these Chinese made mini-amps are a crapshoot. The power ratings are overstated and I wouldn't be surprised if the guts aren't all coming from very few sources, or maybe a single source. If so, if a bad component sneaks in the impact ripples throughout. I'm giving up playing roulette with these mini-amps - went with Made in USA - a lot more expensive, but a lot less headaches.

I purchased the Dayton Audio DTA-2.1 to replace my 15 year old, tired, and partied out Cambridge SoundWorks Model 12 Mick Fleetwood Signature Series 2.1 amp. The DTA Amp is amazing. The amp is half the size, produces no heat, and comes with a crystal clear long range on-board BlueTooth. The clarity, stereo separation, and overall tone meets or exceeds the CSE 2.1 amp. The DTA has plenty of power. Note: I also tried 2 other popular class D 2.1 amps. They both fell way short in either power, tone, and lack of distortion. The DTA amp coupled with the CSW satellite speakers and the sub woofer in the carry case will continue to blow your flip-flops off for the 2020 beach season and beyond. :)

With this connected to an okay set of old-as-heck monitors and an old passive sub I found in the basement—this is seems like a great bang for the buck. Almost two month in, and I love it. It slaves to the TV and gets a lot of use as a Bluetooth. Plenty of power for my average living room if I feel like blowing it up. Sure, could probably drop a buncha money somewhere else, but this didn’t cost much for the power. Haven’t noticed any distortion or odd sound qualities. Bad stereos annoy me, and I haven’t any complaints yet. Oh and it’s tiny! Wish it had a remote.

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.

This unit causes significant audio issues with my analogue audio. Constant buzzing whenever there is draw from the power supply. Seems the power supply has some significant issues. Bluetooth works fine of course, but switching to headphones I still get the buzzing from anything on the same power circuit. Even a power conditioner I purchased did not correct the issue.

muy pequeño versatil y bueno por su tamaño
