Product details

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


The DTA-2.1BT2 is a discrete whole system amplifier that provides output for 2 speakers and a passive subwoofer. This design allows you to create a compact 2.1 setup for virtually any room whether it be an office, bedroom, or even a small home theater. The 2 x 50W output power is more than enough for most bookshelf speakers, and the subwoofer output of 100W is ideal for a small subwoofer.


The reason the DTA-2.1BT2 is able to produce this exceptional power in such a small package is the Class D topology that is being utilized. This amplifier technology also provides high-efficiency for a low power draw on your electrical system.


The DTA-2.1BT2 features the three most popular audio inputs: 3.5 mm, stereo RCA, and of course Bluetooth. The 3.5 mm and RCA inputs are found on the rear of the unit labeled Aux 1 and Aux 2, respectively. The Bluetooth connectivity is extremely convenient for wireless audio playback and is a key feature for any audio enthusiast.


The front plate of the DTA-2.1BT2 features 3 knobs providing a gentile tactile feel. The first knob on the left provides control over the subwoofer output. The second knob is a tone control that allows you to attenuate the sonic signature of your speakers. The final and largest knob is the volume control located on the right of the faceplate. The front plate also features an adjustable crossover frequency to fine tune your system (50-120 Hz). There is a discrete push button power switch/source selector located on the front of the unit on the left-hand side. The DTA-2.1BT aesthetics offer you an attractive black aluminum case that can easily be the focal point of your 2.1 system.



Specificaties voor: DTA-2.1BT2 100W 2.1 Class D Bluetooth Amplifier with Sub Frequency Adjustment

  • Rated power output (RMS) Het elektrisch vermogen uitgedrukt in watt (W) dat een versterker kan uitgeven per uitgangskanaal, zonder dat de versterker beschadigt of gaat 'clippen'. RMS = Root Mean Square. 2 x 50 Watts at 4 ohms + 1 x 100 Watts at 4 ohms
  • Bridged power output (RMS) Het elektrisch vermogen uitgedrukt in watt (W) dat een versterker kan uitgeven per gebrugd uitgangskanaal (2 x stereo naar 1 x mono output), zonder dat de versterker beschadigd of gaat 'clippen'. RMS = Root Mean Squeare. -
  • Minimum load Geeft de minimale belasting weer wat een versterker kan aansturen in ohm's. Een lagere impedantie van een speaker wordt afgeraden wanneer deze lager is dan de minimale impedantie van een versterker. Een versterker werkt het beste wanneer de impedantie van de speaker binnen het impedantie bereik valt wat de versterker voorschrijft (bijvoorbeeld 4 tot 8 ohm). 4 ohm
  • Signal-to-noise ratio (SNR) Geeft de sterkte weer van het gewenste signaal in verhouding tot het vermogen van de aanwezige ruis. Algemeen geldt dat hogere waardes wenselijk zijn. 86 dB

    Nice amp. I have connected with a Bose 2.1 speaker system. I had to connect the sub output to left and right on the sub, working great so far. Bluetooth also works great.

    I bought this amp to replace my cheap Chinese TPA3118 2.1 amp for my boombox project.
    This amp has a good quality case, brushed metal box, nicely painted. The dials are turned with a silent "click", it is a joy to play with them. It is important to note that it has a 24V 4A PSU, that is enough for nearly 90W continuous power.

    I use it with BT connection, using it with a Samsung Galaxy phone. Sound is clear, no background noise during playback. The phone BT input is really powerful at max volume, it easily makes the amp clipping at 66-75% of the volume dial, so I keep my phone BT volume around 80%, allowing me a more granular volume control on the amp.

    I made some measurements in stereo mode (not 2.1) with 2*4 Ohm dummy loads, with its default PSU, in BT mode. I have a cheap DSO150 Oscope, so it might not be 100% accurate, but hope it helps.

    Clean power @1KHz (before visible clipping on the sine wave): 13.5-14V, =45-48W clean power / channel (<1%), that is excellent, knowing that the maximum power is 50W. The power supply is probably capable to deliver far beyond its specs, as 100W clean power would require at least 4.5-4.8A, that it can surely produce, at least for a short time. The PSU became only slightly warm during this, no overload protection kicked at maximum clean power at least not during the stress test (1-2 minutes).

    Frequency response is pretty flat vs. 1kHz, though it fades by -3dB above 16kHz:
    @30Hz -1.1dB,
    @40Hz -0.6dB
    @5kHz -0.3dB
    @10kHz -1.6dB
    @14kHz -2,4dB
    @20kHz -4.6dB

    Overall, I like this amp for the price (it is more pricey in Europe, unfortunately).
    It costs more than its noname cousins, but every piece of it tells about the many hours of engineer efforts, to make a decent product overall.

    Amazing lil fella, great sound in a tiny package! Blown away by the build quality as well.
